MP252 Multimedia Home Gateway  8. Configuring VoIP Parameters Version 3.4.0  77  June 2011 8.1.1  Configuring Proxy Redundancy The Redundant Proxy feature allows the configuration of a backup SIP proxy server to increase Quality of Service (QoS). Once this feature is enabled, MP252 identifies cases where the primary proxy does not respond to SIP signaling messages. In these cases, MP252 registers to the redundant proxy and seamlessly continues normal functionality, without any noticeable connectivity failure or malfunction with the primary proxy. The Redundant Proxy feature includes two operational modes:  Asymmetric mode: This mode assigns the primary proxy a higher priority for registration over the redundant proxy. Once MP252 is registered to the primary proxy, it sends keep-alive messages (using SIP OPTIONS messages) to the primary proxy. If the primary proxy does not respond, MP252 registers to the redundant proxy, but continues sending keep-alive messages to the primary proxy. If the primary proxy responds to these keep-alive messages, MP252 re-registers to the primary proxy.  Symmetric mode: In this mode, both proxies are assigned the same priority for registration. Once MP252 is registered to a proxy (primary or redundant), it sends keep-alive messages to this proxy. MP252 switches proxies only once the proxy to which it has registered does not respond.  In both modes, the following applies:  If MP252 is not registered (i.e., if the proxy server - redundant or primary - to which MP252 currently tries to register does not respond), MP252 attempts to register to an alternative proxy. These attempts continue until MP252 successfully registers.  If this feature is enabled and you reboot MP252, it registers to the last proxy to which it was trying to register (not necessarily to the primary proxy). ¾ To configure proxy redundancy: 1.  From the menu bar, click the Voice Over IP menu; the Signaling Protocol tab screen appears. 2.  Define a primary proxy server (under the SIP Proxy and Registrar group): a.  Select the ‘Use SIP Proxy’ check box. b.  In the 'Host Name or Address' field, enter the primary proxy's IP address. c.  In the 'Proxy Port' field, enter the primary proxy's port number. 3.  Define a redundancy proxy server (under the SIP Proxy and Registrar group): a.  Select one of the following check boxes: 'Use SIP Registrar' or 'Use SIP Proxy IP and Port for Registration'. a.  Select the 'Use Redundant Proxy' check box.  b.  In the 'Redundant Proxy Address' field, enter the redundant proxy's IP address or DNS name. c.  In the 'Redundant Proxy Port' field, enter the redundant proxy's port number.

MP252 Multimedia Home Gateway  80  Document #: LTRT-23504  User's Manual  Table 8-2: Dialing Tab Parameters Description Parameter  Description Dialing Parameters Dialing Timeout  Defines the duration (in seconds) of allowed inactivity between dialed digits. When you work with a proxy, the number you have dialed before the dialing process has timed out is sent to the proxy as the user ID to be called. This isuseful for calling remote parties without creating a speed dial entry (assuming the remote party is registered with the proxy). Phone Number Size  Defines the maximum length of shortcut numbers that you can enter and themaximum number of digits that you can dial. Enabled dialing complete key  When selected (default), you can define a key that when pressed forces MP252 to make a call to the dialed digits even if there is no match in the dialplan or digit map. The key is defined in the ‘Complete dialing key’ field, whichappears when this parameter is selected.  Note: This parameter appears only in 'Advanced' mode. Complete dialing key  Defines the key that when pressed forces MP252 to make a call to the dialeddigits even if there is no match in the dial plan or digit map. The default valueis the pound (#) key. Note: This parameter is available only if the ‘Enabled dialing complete key’ isselected. Dial Tone Timeout Defines the duration of the dial tone (in seconds). If the limit is exceeded, thedial tone stops and you a reorder tone is played. Reorder Tone Timeout Defines the duration (in seconds) of the reorder tone. The reorder tone is played, for example, when MP252 receives a SIP 486 response. If the limit isexceeded, the reorder tone stops and a howler tone is played. Note: This parameter appears only in 'Advanced' mode. Unanswered call timeout  Defines the timeout before MP252 automatically sends a SIP CANCEL message. When MP252 makes a call and the other side doesn’t answer, MP252 sends a CANCEL message after this timeout. Note: This parameter appears only in 'Advanced' mode. Howler Tone Timeout  Defines the duration (in seconds) of the howler tone. If the limit is exceeded,the howler tone stops playing. The howler tone informs a user that the user'sphone has been left in an off-hook state. Note: This parameter appears only in 'Advanced' mode. Flash min  Defines the duration (in ms) after which you can begin to perform a flash hook. Flash max  Defines the maximum duration (in ms) that the flash hook button can be pressed, after which the call is disconnected. Enable Re-Answer Timeout  When selected, the ‘Re-Answer Timeout’ field appears, allowing you to define the timeout after on-hooking an active call and then off-hooking it again. Once this time expires and the phone has not been off-hooked again,the call is disconnected. Send DTMF Out-Of- Band Defines how the DTMF tones are sent (‘Inband’, ‘RFC2833’, or ‘Via SIP’). DTMFs are the tones generated by your telephone's keypad. Note: This parameter appears only in 'Advanced' mode.
MP252 Multimedia Home Gateway  8. Configuring VoIP Parameters Version 3.4.0  81  June 2011 Parameter  Description Digit Map  Defines formats (or patterns) for the dialed number. A match to one of the defined patterns terminates the dialed number. For an explanation on digit map syntax, see Section 8.2.1 on page 81. Note: This parameter appears only in 'Advanced' mode. Dial Plan  Defines patterns to translate to specific SIP destination addresses. For dial plan syntax rules for patterns entered to the left of the '=' sign, see Section 8.2.1 on page 81. Note: This parameter appears only in 'Advanced' mode. Key Sequence Flash keys sequence style Defines the key sequence with the flash button:  ‘Flash only’ (default) = uses only the phone's Flash button. There are three scenarios:  9 During an existing call, if the user presses Flash, the call is put on hold, a dial tone is heard and the user is able to initiate a second call.Once the second call is established, on-hooking transfers the first (held) call to the second call.  9 During an existing call, if the user presses Flash, the call is put on hold and a dial tone is heard. The user can initiate a second call andestablish a 3-way conference by again pressing Flash after the second call is initiated.  9 During an existing call, if a call comes in (call waiting), pressing Flashputs the active call on hold and answers the waiting call; pressing Flash again toggles between these two calls.  ‘Flash + digits sequence’ = Flash button with a key sequence: 9 Flash + 1 holds a call or toggles between two existing calls.  9 Flash + 2 makes a call transfer. 9 Flash + 3 establishes a 3-way conference.  'Send Flash Hook Via SIP' = you can modify the SIP INFO message that is sent upon Flash. You can change the Content Type header field and Message Body field. Note: This parameter appears only in 'Advanced' mode. SIP INFO Header When the key sequence is set to 'Send Flash Hook Via SIP', you can modifythe Content Type header field of the SIP INFO message.  For example: "application/broadsoft; version = 1.0" Note: This parameter appears only when the ‘Flash keys sequence style’ field is set to 'Send Flash Hook Via SIP'. SIP INFO Body  When the key sequence is set to 'Send Flash Hook Via SIP', you can modifythe Message Body field of the SIP INFO message.  For example: " event flashhook" Note: This parameter appears only when the ‘Flash keys sequence style’ field is set to 'Send Flash Hook Via SIP'.  8.2.1 Syntax for Digit Maps and Dial Plans Digit maps and dial plans are defined using special syntax rules, configured in the 'Dialing' screen (see Section 8.2 on page 78).  Digit Maps: A phone's digit map allows MP252 to know when an entered telephone number is complete and therefore, when it should initiate the call. If the phone digit map is defined incorrectly, MP252 might start to dial before the telephone user has entered
MP252 Multimedia Home Gateway  82  Document #: LTRT-23504  User's Manual  all the required digits. A digit map is defined either by a (case insensitive) "string" or by a list of strings.  Each string in the list is an alternative numbering scheme, specified either as a set of digits or as an expression over which MP252 attempts to find a shortest possible match.  The syntax that can be used in each numbering scheme is described in the table below.  Dial Plans: A dial plan translates specific patterns into specific SIP destination addresses. For example, dial plan rule "4xxx=Line_\\\@10.1.2.3" sends a dialed number consisting of the digit “4” followed by any three digits to IP address 10.1.2.3. The syntax of the pattern on the left of the '=' sign is described in the table below. Table 8-3: Dial Plan (for Left of '=' Sign) and Digit Map Syntax Type  Syntax Digit  A digit from "0" to "9". DTMF  A digit, or one of the symbols "A", "B", "C", "D", "#", or "*".  Extensions may be defined. Wildcard  The symbol "x" which denotes any digit ("0" to "9"). Range  One or more DTMF symbols enclosed between square brackets ("[" and "]"). Sub-range  Two digits separated by a hyphen ("-") which matches any digit between and including the two. The subrange can only be used inside a range construct, i.e., between "[" and "]". Position A period (".") which matches an arbitrary number, including zero, of occurrences ofthe preceding construct.  For example: [2-9]11|0|100|101|011xxx.|9011xxx.|1[2-9]xxxxxxxxx|91[2-9]xxxxxxxxx|9[2-9]xxxxxx|*xx|[8]xxxx|[2-7]xxx  [2-9]11: 911 rule: 211, 311, 411, 511, 611, 711, 811, 911 are dialled immediately   0: Local operator rule   100: Auto-attendant default extension   101: Voicemail default extension   011xxx.: International rule without prefix   9011xxx.: International rule with prefix   1[2-9]xxxxxxxxx: LD rule without prefix   91[2-9]xxxxxxxxx: LD rule with prefix   9[2-9]xxxxxx: Local call with prefix   *xx: 2-digit star codes   [1-7]xx: A regular 3-digit extension that does not start with 9 or 8 is dialed immediately   [2-7]xx: A regular 3-digit extension that does not start with 9, 8, or 1 is dialed immediately   [2-7]xxx: A regular 4-digit extension that does not start with 9, 8, or 1 is dialed immediately   [8]xxx: A 3-digit extension prefixed with an 8 (routes calls directly to voicemail of extension xxx)    [8]xxxx: A-4 digit extension prefixed with an 8 (routes calls directly to voicemail of extension xxxx)

Figure 8-4: Media Streaming Tab Screen  4.  Configure the parameters, as required. For a description of the parameters displayed on this screen, see Table 8-4. 5.  Click OK to save your settings. Table 8-4: Media Streaming Tab Parameters Description Parameter  Description Media Streaming Parameters Local RTP Port Range - Contiguous Series of 8 Ports Starting From: Defines the port range for Real Time Protocol (RTP) voice transport. DTMF Relay RFC 2833 Payload Type   Defines the RTP payload type used for RFC 2833 DTMF relay packets. The range is 0-255. The default is 101. G.726/16 Payload Type Defines the RTP payload type used for 16 kbps G.726 packets. The range is0-255. The default is 98.
MP252 Multimedia Home Gateway  84  Document #: LTRT-23504  User's Manual  Parameter  Description Quality of Service Parameters Type of Service (Hex)  This is a part of the IP header that defines the type of routing service to be used to tag outgoing voice packets originated from MP252. It is used to inform routers along the way that this packet should get specific QoS. Leavethis value as 0xb8 (default) if you are unfamiliar with the Differentiated Services IP protocol parameter. Codecs 1st - 6th Codec  Defines the voice codec. For more information, see 8.3.1 on page 84.   8.3.1 Configuring Codecs Codecs define the method of relaying voice data. Different codecs have different characteristics, such as data compression and voice quality. For example, G.723 is a codec that uses compression, so it is good for use where bandwidth is limited but its voice quality is not as good compared to other codecs such as the G.711. 8.3.1.1 Supported Codecs To make a call, at least one codec must be enabled. Moreover, all codecs may be enabled for best performance. When you start a call to a remote party, your available codecs are compared against the remote party's to determine the codec used. The priority by which the codecs are compared is according to their order of appearance in the table (descending order). To change the priorities, rearrange the codecs in the required order. If there is no codec that both parties have made available, the call attempt fails. Note that if more than one codec is common to both parties, you cannot force which of the common codecs that were found are used by the remote party's client. If you do wish to force the use of a specific codec, leave only that codec checked. 8.3.1.2 Packetization Time The Packetization Time is the length of the digital voice segment that each packet holds. The default is 20 millisecond packets. Selecting 10 millisecond packets reduces the delay but increases the bandwidth consumption.  8.4  Configuring Voice and Fax The procedure below describes how to configure the voice and fax parameters. ¾ To configure voice and fax parameters: 1.  In the 'Voice Over IP' screen, click the Voice and Fax tab; the following screen appears.  Figure 8-5: Voice and Fax Tab Screen

The AGC mechanism adjusts the level of the received signal to maintain a steady (configurable) volume level. Automatic Gain Control Direction  Defines the AGC direction (local or remote user). Note: This parameter appears only if the ‘Enable Automatic Gain Control’ check box is selected. Target Energy  Defines the signal energy value (in dBm) that the AGC attempts to attain. The range is 0 to -63 dBm. The default value is -19 dBm. Note: This parameter appears only if the ‘Enable Automatic Gain Control’ check box is selected. Jitter Buffer Minimum Delay  Defines the initial and minimal delay of the adaptive jitter buffer mechanism,which compensates for network problems. The value should be set according to the expected average jitter in the network (in milliseconds). The default is 35 msec. Optimization Factor  Defines the adaptation rate of the jitter buffer mechanism.  Higher values cause the jitter buffer to respond faster to increased network jitter. The default is 7. Silence Compression Enable Silence Compression  Enables silence compression, which reduces the network bandwidth consumption. The default is disabled. Enable G.711/G.726 Comfort Noise Enables the Comfort Noise generation feature. When enabled and silence is detected, MP252 transmits a series of parameters called Silence InformationDescriptor (SID), which are used to reproduce the local background noise atthe remote (receiving) side. Note: This parameter appears only if the ‘Enable Silence Compression’ check box is selected. Echo Cancellation Enable Echo Cancellation  Enables (default) echo cancellation (disabling echo cancellation should be done for testing purposes only).  Fax and Modem Settings Fax Transport Mode  Selects the way fax calls are handled: 9 Transparent = Fax is transferred in-band (like a voice call) - can be used if the codec is G.711 9 T.38 Relay = Fax is relayed to the remote side according to the T.38standard 9 Voice Band Data = Switch to G.711 via SIP messaging 9 Bypass = An automatic switch to AudioCodes' proprietary payload type (102, 103). Max Rate Defines the maximum fax rate.   2.4 Kbps, 4.8 Kbps, 7.2 Kbps, 9.6 Kbps, 12 Kbps or 14.4 Kbps (default). Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38 Relay’.
MP252 Multimedia Home Gateway  8. Configuring VoIP Parameters Version 3.4.0  87  June 2011 Parameter  Description Max Buffer Defines the maximum amount of T.38 data stored on the MP252. The valid range is 128 to 2048. The default is 1024. Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38 Relay’. Max Datagram Defines the maximum total size of TCP/UDPTL packets that can be receivedat the remote gateway. The valid range is 160 to 1020. The default is 320. Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38 Relay’. Image Data Redundancy Level Defines the level for output Image Data (2400…14400 bps).   0 = No redundancy  1 to 3 = Redundancy level Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38 Relay’. T30 Control Data Redundancy Level  Defines the redundancy level for output T.30 Control Data (300 bps).  0 = No redundancy  1 to 7 = Redundancy level Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38 Relay’. Fax Relay Jitter Buffer Delay Defines the Fax Relay Jitter Buffer.  0 = Adaptive Jitter Buffer. The MP252 sets the Jitter Buffer size automatically and then adapts it according to network conditions.  1 to 511 = Fixed Jitter Buffer size (in msec). Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38 Relay’. Error Correction Mode Enables (default) fax error correction mode (ECM). Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38 Relay’. Fax Bypass Payload Type Defines the payload type for fax in Bypass mode. Note: This parameter appears only if 'Fax Transport Mode' is set to ‘Bypass’.Modem Transport Mode Selects the way modem calls are handled:  Transparent = Data is transferred in-band (like a voice call). This can be used if the codec is G.711.  Voice Band Data = Switch to G.711 via SIP messaging.  Bypass = An automatic switch to AudioCodes' proprietary payload type (102, 103). Note: If the Fax transport mode is Bypass or VBD, it must match the Modemtransport mode. Modem Bypass Payload Type  Defines the payload type for modems in Bypass mode. Note: This parameter appears only if 'Modem Transport Mode' is set ‘Bypass’. Fax/Modem Bypass Codec  Defines the codec for the VBD and Bypass modes. PCMA (default) or PCMU.  G.711 64 kbps A-Law -OR- G.711 64 kbps u-Law
MP252 Multimedia Home Gateway  88  Document #: LTRT-23504  User's Manual  Parameter  Description CED Transfer Mode   By Fax Relay: When MP252 is the receiver side, Switch to Fax relay is enabled upon CED. This allows a high reliable fax-over-IP call establishment at the beginning of CED tone.   In Voice Or PCM Bypass: When MP252 is the receiver side, to avoid possible conflicts with low-speed modems, the CED (ANS) relay by FoIP protocol may be disabled by setting the CED transfer mode to ‘In Voice Or PCM Bypass’. In this case, MP252 does not initiate the Fax Relay on detecting CED tone in absence of CNG, but switches to VBD or remains in voice mode (depends on the Modem Transport Mode). MP252 switches to FoIP later when it defines exactly that a monitored call is the fax call (CED and CND or V.21 Preamble). Enable CNG Detection  Enables detection of the fax CNG signal. When the local fax machine connected to MP252 receives a fax, MP252 switches to T.38 fax relay upon detection of the CED signal from the remote fax. If the local fax machine sends a fax, MP252 switches to T.38 only after detecting the CNG signal from the local side and the CED signal from the remote side. If this check box is selected, MP252 switches to T.38 relay immediately upon detection of theCNG signal from the local side, without waiting for the CED signal from the remote side. The default is disabled. Switch To Fax Only By The Answering Side Typically, switching to fax mode is the responsibility of the answering side. However, in some cases, the sending machine can also switch to fax mode.If this check box is marked, the sending machine does not switch to fax, but allows the answering side to detect the fax and switch to fax mode.   8.5  Configuring Supplementary Services The procedure below describes how to configure the services parameters. ¾ To configure supplementary services: 1.  In the 'Voice Over IP' screen, click the Services tab; the following screen appears.  Figure 8-6: Services Tab Screen

Version 3.4.0  105  July 2011 MP252 Multimedia Home Gateway  11. Quality of Service 11  Quality of Service Network-based applications and traffic are growing at a high rate, producing an ever-increasing demand for bandwidth and network capacity. For obvious reasons, bandwidth and capacity cannot be expanded infinitely, requiring that bandwidth-demanding services be delivered over existing infrastructure, without incurring additional, expansive investments. The next logical means of ensuring optimal use of existing resources are Quality of Service (QoS) mechanisms for congestion management and avoidance. QoS refers to the capability of a network device to provide better service to selected network traffic. This is achieved by shaping the traffic and processing higher priority traffic before lower priority traffic. As QoS is dependent on the "weakest link in the chain", failure of but a single component along the data path to assure priority packet transmission can easily cause a VoIP call or a Video on Demand (VoD) broadcast to fail miserably. QoS must therefore obviously be addressed end-to-end. The following are the potential bottleneck areas that need be taken into consideration when implementing an end-to-end QoS-enabled service.  The Local Area Network: LANs have finite bandwidth, and are typically limited to 100 Mbps. When given the chance, some applications consume all available network bandwidth. In business networks, a large number of network-attached devices can lead to congestion. The need for QoS mechanisms is more apparent in wireless LANs, where bandwidth is even more limited (typically no more than 20 Mbps on 802.11g networks).  The Broadband Router: All network traffic passes through and is processed by the broadband router. It is therefore a natural focal point for QoS implementation. Lack of sufficient buffer space, memory or processing power, and poor integration among system components can result in highly undesirable real-time service performance. The only way to assure high QoS is the use of proper and tightly-integrated router operating system software and applications, which can effectively handle multiple real-time services simultaneously.  The Broadband Connection: Typically, the most significant bottleneck of the network, this is where the high speed LAN meets limited broadband bandwidth. Special QoS mechanisms must be built into routers to ensure that this sudden drop in connectivity speed is taken into account when prioritizing and transmitting real-time service-related data packets.  The Internet: Internet routers typically have a limited amount of memory and bandwidth available to them, so that congestions may easily occur when links are over-utilized, and routers attempt to queue packets and schedule them for retransmission. One must also consider the fact that while Internet backbone routers take some prioritization into account when making routing decisions, all data packets are treated equally under congested conditions.   Note:  For recommended QoS configuration see Section 11.7 on page 120.
MP252 Multimedia Home Gateway  106  Document #: LTRT-23504  User's Manual  11.1 QoS Wizard The QoS wizard allows you to configure your QoS parameters according to predefined profiles, with just a few clicks. A chosen QoS profile automatically defines QoS rules, which you can view and edit in the rest of the QoS tab screens. The QoS wizard also allows you to define the WAN bandwidth. ¾ To use the QoS Wizard: 1.  From the menu bar, click the QoS menu link; the ‘Quality of Service’ screen appears with the QoS Wizard tab selected by default. Figure 11-1: QoS Wizard Tab Screen  2.  Define bandwidth limitation. From the 'WAN Devices Bandwidth (Rx/Tx)' drop-down list, select ‘User Defined’ if you want to define specific Rx and Tx bandwidth limitations, or select  the Rx/Tx optional values provided in the drop-down list.
MP252 Multimedia Home Gateway  11. Quality of Service Version 3.4.0  107  June 2011 3.  In the QoS Profiles group, select a QoS profile. 4.  Click OK.   Note:  Selecting a new QoS profile deletes all previous QoS settings.   11.2 Traffic Shaping Traffic Shaping is the solution for managing and avoiding congestion where a high speed LAN meets limited broadband bandwidth. A user may have, for example, a 100 Mbps Ethernet LAN with a 100 Mbps WAN interface router. The router may communicate with the ISP using a modem with a bandwidth of 2 Mbps. This typical setup makes the modem, having no QoS module, the bottleneck. The router sends traffic as fast as it is received, while its well-designed QoS algorithms are left unused. Traffic shaping limits the bandwidth of the router, artificially forcing the router to be the bottleneck. A traffic shaper is essentially a regulated queue that accepts uneven and/or bursty flows of packets and transmits them in a steady, predictable stream so that the network is not overwhelmed with traffic. While Traffic Priority allows basic prioritization of packets, Traffic Shaping provides more sophisticated definitions such as:  Bandwidth limit for each device  Bandwidth limit for classes of rules  Prioritization policy  TCP serialization on a device You can also define QoS traffic shaping rules for a default device. These rules are used on a device that has no definitions of its own. This enables the definition of QoS rules on Default WAN, for example, and their maintenance even if the PPP or bridge device over the WAN is removed. MP252 also supports dynamic traffic shaping during a call. Traffic shaping is critical in residential VoIP gateways because of the bottleneck created in the ADSL or Cable modem, mainly in the upload direction. Dynamic traffic shaping ensures a minimum bandwidth for VoIP calls. Without dynamic traffic shaping, traffic shaping limits the bandwidth at all times, even if the user is not making a VoIP call and therefore, the service provider needs to configure the QoS traffic shaping transmit (Tx) bandwidth according to the user's specific upload bandwidth. Configuring a lower value results in a lower upload bandwidth (not only during VoIP calls). Dynamic traffic shaping enables the service provider to configure two upload traffic shaping bandwidth parameters:  "Tx Bandwidth" - for all traffic  "Tx Bandwidth during Call" - for VoIP calls MP252 normally uses the "Tx Bandwidth" value. When the user makes a VoIP call (i.e. any phone/s connected to MP252 is ringing or off-hook), MP252 switches to use the "Tx Bandwidth during Call" value. 11.2.1  Device Traffic Shaping The procedure below describes how to configure traffic shaping. ¾ To add a traffic shaping device: 1.  From the menu bar, click the QoS menu, and then click the Traffic Shaping tab.
MP252 Multimedia Home Gateway  108  Document #: LTRT-23504  User's Manual  Figure 11-2: Quality of Service – Traffic Shaping Screen  2.  Click the New   icon; the 'Add Device Traffic Shaping’ screen appears. Figure 11-3: Add Device Traffic Shaping Screen  3.  From the ‘Device’ drop-down list, select the device for which you want to shape traffic. The list includes all interfaces (e.g., All LAN Devices, All WAN Devices) and VPNs such as PPoE, PPTP and L2TP (if defined). For example, select 'WAN Ethernet', and then click OK; the ’Edit Device Traffic Shaping’ screen appears. Figure 11-4: Edit Device Traffic Shaping Screen
MP252 Multimedia Home Gateway  11. Quality of Service Version 3.4.0  109  June 2011 4.  Under the Tx Traffic Shaping group, from the ‘Tx Bandwidth’ drop-down list, select ‘Specify’ and define the MP252’s maximum transmission bandwidth rate in the corresponding field. The purpose is to limit the bandwidth of the WAN interface to that of the weakest outbound link, for instance, the DSL speed provided by the ISP. This forces MP252 to be the network bottleneck, where sophisticated QoS prioritization can be performed. If the device’s bandwidth is not limited correctly, the bottleneck is an unknown router or modem on the network path, rendering MP252 QoS useless. To configure unlimited bandwidth, select ‘Unlimited’. 5.  Under the Rx Traffic Policing group, from the ‘Rx Bandwidth’ drop-down list, select ‘Specify’ and define the MP252’s maximum receive bandwidth rate in the corresponding field. This limits MP252’s bandwidth receipt rate to that of the DSL modem. 6.  From the ‘TCP Serialization’ drop-down list, select whether to enable TCP serialization. The screen refreshes, displaying the ’Maximum Delay’ field. This allows you to define the maximum allowed transmission time frame (in milliseconds) of a single packet. Any packet that requires a longer time to be transmitted is fragmented to smaller sections. This avoids transmission of large, bursty packets that may cause delay or jitter for real-time traffic such as VoIP. 7.  Select the ‘Enable Dynamic Traffic Shaping’ check box if you want to configure traffic shaping specifically for VoIP calls (see Section 11.2 on page 107). When selected, the ‘Tx Bandwidth During VoIP Call’ field appears. Enter the bandwidth for VoIP calls. MP252 normally uses the "Tx Bandwidth" parameter value. When the user makes a VoIP call (i.e. any phone connected to MP252 is ringing or off-hook), MP252 switches to use the "Tx Bandwidth during Call" parameter value.   11.2.2 Shaping Classes The bandwidth of a device can be divided to reserve constant portions of bandwidth to user-defined traffic types. Such a portion is known as a Shaping Class. When not used by its user-defined traffic type or owner (for example, VoIP), the class is then available to all other traffic. However when needed, the entire class is reserved solely for its owner. Moreover, you can limit the maximum bandwidth that a class can use even if the entire bandwidth is available. When a shaping class is defined for a specific traffic type, two shaping classes are created. The second class is the 'Default Class', responsible for all the packets that do not match the defined shaping class or any other classes that may be defined on the device. This can be viewed in the Class Statistics screen. ¾ To add a shaping class: 1.  From the menu bar, click the QoS menu, and then click the Traffic Shaping tab. 2.  Click the Edit   icon corresponding to the added Device (e.g., WAN); the 'Edit Device Traffic Shaping' screen appears. 3.  Under the Tx Traffic Shaping group, click the New   icon; the 'Add Shaping Class' screen appears. Figure 11-5: Add Shaping Class Screen  4.  In the ‘Name’ field, enter a name for the class, and then click OK; the 'Edit Device Traffic Shaping' screen appears.
MP252 Multimedia Home Gateway  110  Document #: LTRT-23504  User's Manual  5.  Edit the newly added shaping class, by clicking the corresponding Edit  icon; the 'Edit Shaping Class' screen appears. Figure 11-6: Edit Shaping Class  6.  In the ‘Name’ field, modify the class name, if required. 7.  From the ‘Class Priority’ drop-down list, select the priority level for the class, where zero is the highest and seven the lowest. 8.  In the ‘Bandwidth’ field, define the bandwidth for the class: • Reserved: reserved (i.e., guaranteed) bandwidth (Committed Information Rate / CIR) in kbps. • Maximum: specify the maximum bandwidth 9.  From the ‘Policy’ drop-down list, select the policy for routing packets within the class: • Priority: Priority queuing uses multiple queues so that traffic is distributed among queues based on priority. This priority is defined according to packet priority, which can be defined explicitly by a DSCP value or an 802.1p value. • FIFO: First In First Out. This priority queue ignores any previously-marked packet priority. • Fairness: The fairness algorithm ensures no starvation by granting all packets a certain level of priority. • RED: Random Early Detection. Utilizes statistical methods to drop packets in a ‘probabilistic’ way before queues overflow. Dropping packets in this way slows a source down enough to keep the queue steady and reduces the number of packets that would be lost when a queue overflows and a host is transmitting at a high rate. 10.  From the ‘Schedule’ drop-down list, select the scheduler rule (defined in Section 4.5.1 on page 43) that defines the time segments during which the class can be active. By default, the class is always active. 11.  Click OK to save your settings.   11.2.2.1 Class Rules Class rules define which packets belong to the class. Without class rules, the shaping class has no effect. Each class can have outbound and inbound rules for outgoing and incoming traffic respectively. For example, you can define that all outgoing packets from computer A in your LAN belong to your VoIP class. These packets are limited to the class settings (bandwidth, schedule, etc.). In addition, you can define the traffic protocol and priority for each rule (this is not mandatory as in Traffic Priority rules). 11.2.2.1.1 Inbound and Outbound Data
MP252 Multimedia Home Gateway  11. Quality of Service Version 3.4.0  111  June 2011 MP252 can control outgoing data easily. It can queue packets, delay them, give precedence to other packets, or drop them. This helps in resolving upload (Tx) traffic bottlenecks and in most cases is sufficient. However, in the case of download (Rx) traffic bottlenecks, the ability to control the flow is much more limited. MP252 cannot queue packets, since in most cases the LAN is much faster than the WAN and when MP252 receives a packet from the WAN, it passes it immediately to the LAN. QoS for ingress data has the following limitations, which do not exist for outgoing data:  QoS can only be applied to TCP streams (UDP streams cannot be delayed)  No borrowing mechanism  When reserving Rx bandwidth, it is strictly taken from the bandwidth of all other classes
MP252 Multimedia Home Gateway  112  Document #: LTRT-23504  User's Manual  In addition, MP252 cannot control the behavior of its WAN (usually the ISP), which may not have proper QoS handling. Let’s look at a scenario of downloading a large file and surfing the Internet at the same time. Downloading the file is distinguished by small requests, followed by very large responses. This may result in blocking HTML traffic at the ISP. A solution for such a scenario is limiting the bandwidth of low-priority TCP connections (such as file download). To add outbound and inbound class rules, see 11.3 on page 112.   Note:  The hierarchy of the class rules is determined by the order of their addition to the class. For example, if your first rule is match packets with any source address, any destination address, and any protocol to this class; then all packets traversing MP252 are associated with the specific class. Any rules defined later do not have any effect.   11.3 Traffic Priority Traffic Priority allows you to manage and avoid traffic congestion by defining inbound and outbound priority rules for each device on your MP252. These rules determine the priority assigned to packets traveling through the device. QoS parameters (DSCP marking and packet priority) are set per packet, on an application basis. You can set QoS parameters using flexible rules, according to the following parameters:  Source/destination IP address, MAC address or host name  Device  Source/destination ports  Limit the rule to specific days and hours MP252 supports two priority marking methods for packet prioritization:  DSCP  802.1p Priority The matching of packets by rules is connection-based, known as Stateful Packet Inspection (SPI), using the same connection-tracking mechanism used by the firewall. Once a packet matches a rule, all subsequent packets with the same attributes receive the same QoS parameters, both inbound and outbound. A packet can match more than one rule, and therefore:  The first class rule has precedence over all other class rules (scanning is stopped once the first rule is reached).  The first traffic-priority (classless) rule has precedence over all other traffic-priority rules.  There is no prevention of a traffic-priority rule conflicting with a class rule. In this case, the priority and DSCP setting of the class rule (if given) takes precedence.
MP252 Multimedia Home Gateway  11. Quality of Service Version 3.4.0  113  June 2011 Connection-based QoS also allows inheriting QoS parameters by some of the applications that open subsequent connections. For instance, you can define QoS rules on SIP and the rules then apply to both control and data ports (even if the data ports are unknown). This feature applies to all applications that have ALG at firewall:  Any  User Defined (FTP, HTTP, HTTPS, TFTP, IMAP, PING, POP3, SNMP, SMTP, Telnet, L2TP, Traceroute or any other protocol) ¾ To set traffic priority rules: 1.  From the menu bar, click the QoS menu, and then select the Traffic Priority tab; the 'Traffic Priority' screen appears.  Figure 11-7: Traffic Priority Screen  This screen is divided into two identical groups - ’QoS Input Rules’ and ’QoS Output Rules’ - for prioritizing inbound and outbound traffic respectively. Each group lists all the devices on which rules can be set. You can set rules on all devices at once by clicking the New Entry link corresponding to 'All Devices' 2.  After clicking the appropriate New Entry link, the 'Add Traffic Priority Rule' screen appears.

From the ‘Source Address’ drop-down list, select 'Any', 'User Defined' or the host as the source address of the packets sent to or received from the network object. If you have created network objects (see Section 4.5.2 on page 46), then these are also displayed in the list (or you can create one by selecting ‘User Defined’). b.  From the ‘Destination Address’ drop-down list, select the network object for the destination address of the packets sent to or received from the network object. See Step 3 above for a detailed explanation on the options.    c.  From the ‘Protocol’ drop-down list, select the protocol. You can apply the rule to all protocols (i.e., ‘Any’) or select an already defined protocol. You can create a new protocol by selecting ‘User Defined’, and then following the procedure described in Section 4.5.3 on page 47. d.  To match DSCP, select the ‘DSCP’ check box, and then enter the DSCP markings. e.  To match priority, select the ‘Priority’ check box, and then select the priority of the packets.

Select the ‘Set Priority’ check box to add a priority to the rule and then select the priority level (where 0 is the lowest and 7 the highest). This sets the priority of a packet on the connection matching the rule, while routing the packet. c.  Select the ‘Tx Class Name’ check box, and then select the class name that you defined. d.  From the ‘Apply QoS on’ drop-down list, select whether you want to apply the QoS rule on the connection or on the packet. 5.  Select the ‘Log Packets Matched by This Rule’ check box to log the first packet from a connection that matches by this rule. 6.  From the ‘Schedule’ drop-down list, select the time segments during which the rule may be active. By default, the rule is always active (i.e., ‘Always’). If you have defined Scheduler rules (see Section 4.5.1  on page 43), then these are also displayed as options. To define a new one Scheduler rule, select ‘User Defined’. 7.  Click OK to save the settings.  11.4 DSCP Mapping To understand Differentiated Services Code Point (DSCP), one must first be familiarized with the Differentiated Services (DiffServ) model. DiffServ is a Class of Service (CoS) model that enhances best-effort Internet services by differentiating traffic by users, service requirements and other criteria. Packets are specifically marked, allowing network nodes to provide different levels of service, as appropriate for voice calls, video playback or other delay-sensitive applications, via priority queuing or bandwidth allocation, or by choosing dedicated routes for specific traffic flows. DiffServ defines a field in IP packet headers referred to as DSCP. Hosts or routers passing traffic to a DiffServ-enabled network typically mark each transmitted packet with an appropriate DSCP. The DSCP markings are used by DiffServ network routers to appropriately classify packets and to apply particular queue handling or scheduling behavior. MP252 provides a table of predefined DSCP values, which are mapped to 802.1p priority marking method. You can edit or delete any of the existing DSCP setting, as well as add new entries.

In the ‘802.1p Priority’ drop-down list, select an 802.1p priority level (each priority level is mapped to low, medium, or high priority). 5.  Click OK to save your settings.   Note:  The DSCP value overriding the priority of incoming packets with an unassigned value (priority 0, assumed to be a no-priority-set) is ‘0x0’. By default, this value is mapped to 802.1p priority level ‘0 -Low’, which means that such packets receive the lowest priority.
MP252 Multimedia Home Gateway  118  Document #: LTRT-23504  User's Manual  11.5 802.1p Mapping The IEEE 802.1p priority marking method is a standard for prioritizing network traffic at the data link/MAC sub-layer. 802.1p traffic is simply classified and sent to the destination, with no bandwidth reservations established. The 802.1p header includes a 3-bit prioritization field, which allows packets to be grouped into eight levels of priority. MP252 maps these eight levels to three main priorities: high, medium and low. By default, values six and seven are mapped to high priority, which may be assigned to network-critical traffic. Values four and five are mapped to medium priority, which may be applied to delay-sensitive applications, such as interactive video and voice. Values three to zero are mapped to low priority, which may range from controlled-load applications down to ‘loss eligible’ traffic. The zero value is normally used for best-effort traffic. It is the default value for traffic with unassigned priority. ¾ To set 802.1p rules: 1.  From the menu bar, click the QoS menu link, and then click the 802.1p Settings tab; the following screen appears: Figure 11-11: 802.1p Settings Screen  2.

MP252 Multimedia Home Gateway  120  Document #: LTRT-23504  User's Manual  11.7  Configuring Basic VoIP QoS The 'Traffic Shaping' feature only ensures priority to calls that originate from inside MP252. When giving VoIP priority over data, the bottleneck is effectively moved from the Cable / ADSL modem into MP252. To give priority to calls from the LAN, you must define a traffic priority rule (for SIP and RTP from the device on the LAN). This section recommends a minimal QoS configuration that ensures sufficient QoS for VoIP calls when MP252 is connected behind a broadband (cable or DSL) modem with limited uplink bandwidth and the user runs bandwidth-consuming applications on the PC.  Since most modems do not have any priority mechanisms, the Tx bandwidth of MP252 should be limited according to the modem’s uplink bandwidth. Since MP252 automatically gives higher priority to VoIP packets (in its internal queues), it is not necessary to define traffic shaping classes. ¾ To configure basic QoS for VoIP: 1.  From the menu bar, click the QoS menu link, and then click the Traffic Shaping tab; the ‘Traffic Shaping’ screen appears. 2.  Click the New  icon; the screen 'Add Device Traffic Shaping' appears. 3.  From the 'Device' drop-down list, select 'Default WAN Device' (or your PPTP/L2TP connection you have created), and then click OK; the 'Edit Device Traffic Shaping' screen appears. 4.  Limit the Tx bandwidth (in the 'Tx Bandwidth' field) according to your modem’s uplink bandwidth. 5.  To prevent jitter in outgoing RTP packets, from the 'TCP Serialization' drop-down list, select 'Enabled', and then in the 'Maximum Delay' field, define the maximum allowed delay (e.g. 20 milliseconds). This causes long TCP packets to be fragmented when there is an active voice call.

Network Connections 12 Network Connections This chapter provides a detailed description on how to configure the following network connections:  WAN – see Section 12.1 on page 123  LAN – see Section 12.2 on page 143  VLANs – see Section 12.4 on page 173  LAN-WAN Bridging – see Section 12.5 on page 180  12.1  Configuring a WAN Connection This section describes how to configure your WAN Internet (WAN Ethernet or WAN DSL) connection.  The WAN connection is configured in the ‘Network Connections’ screen, which provides a connection wizard that guides you through the network configuration stages.   Notes:  • To quickly configure a basic WAN connection, use the ‘Quick Setup’ screen, as described in Section 7.1 on page 57. • Before configuring the MP252 Internet connection, ensure that you have obtained relevant technical information on the Internet connection type from your Internet Telephony Service Provider (ITSP). For example, whether you are connected to the Internet using a static or dynamic IP address, or what protocols such as PPTP or PPPoE are used to communicate over the Internet. • MP252 automatically detects the physical WAN type (i.e., Ethernet or ADSL). To change the WAN type, you must restore MP252 to factory settings (see Section 18.8). • When connected to ADSL, the LAN4/WAN Ethernet port can be used for Ethernet LAN interface.  • When connected to an external modem through the Ethernet LAN4/WAN port and MP252 obtains an IP address, the ADSL interface is disabled. • If the Automatic Dialer feature is shipped preconfigured (i.e., enabled), then MP252 automatically detects the Internet dialer type and therefore, Internet connection configuration is unnecessary. However, it is recommended to manually configure the Internet connection after the Automatic Dialer process has completed (successfully or not). For more information on the Automatic Dialer feature, see Section 7.2 on page 66.  ¾ To start the Connection Wizard: 1.

Version 3.4.0  185  July 2011 MP252 Multimedia Home Gateway  13. Remote MP252 Management 13  Remote MP252 Management This chapter provides an overview of the MP252 remote configuration and management support. In addition, this chapter describes how to enable and secure remote management, as well configure MP252 through SNMP and TR069. 13.1 Overview MP252 is designed to be mass-deployed. One of the keys to guarantee end-user satisfaction and true toll-quality service in mass field deployment is comprehensive remote configuration and management capabilities:  Automatic and remote configuration updates   Automatic and remote firmware updates  Remote diagnosis of problems reported by the user  Remote collection of statistical information regarding the quality of the service  Remote notifications of problems in the service 13.1.1 Remote Configuration By default, MP252 is provided with factory default settings, which are common to all MP252 devices (except for the MAC address). The factory settings allow the user to connect to MP252's Web interface through the LAN. By default, the WAN interface is configured for DHCP (i.e., automatically obtains its IP address from a DHCP server). The default configuration should not include any VoIP service provider settings (such as a SIP proxy). In some cases, AudioCodes can ship MP252 devices that are pre-configured with some customer-specific parameters. This set of parameters is usually defined as the new "factory settings" for the specific customer. MP252's factory default settings and the current configuration running on MP252 are stored on MP252's non-volatile flash memory. The current configuration can be remotely updated using several configuration interfaces:  HTTP-based Web server  SNMP  TR-069  Configuration file upload/download
MP252 Multimedia Home Gateway  186  Document #: LTRT-23504  User's Manual  Figure 13-1: Remote Management Interfaces  All configuration interfaces access the same internal configuration repository. The configuration file represents the complete set of MP252 configuration parameters. Specific configuration interfaces (e.g. SNMP and TR-069) might support access only to a sub-set of these configuration parameters. At any time, the factory settings can be restored using the Web interface or by pressing the Reset pin-hole button while MP252 is being powered up. The table below lists the main MP252 configuration parameter groups: Table 13-1: Main Configuration Parameter Groups Group  Description VoIP  Parameters relating to the VoIP functionality (e.g. analog interface, SIP signaling, voice and fax, media streaming) WAN Interface   The main WAN Internet connection (this group is also referred to as the "Quick Setup"). Network Connections  Configuration of all network connections (LAN and WAN), including advanced connections such as VLANs. Security  Parameters relating to the internal firewall. QoS  Configuration of Quality of Service parameters such as priorities and traffic shaping. System / Advanced  Configuration of system parameters such as Remote Update and Remote Access and advanced parameters such as Dynamic DNS, UPnP. A typical set of parameters that a service provider may want to configure include the following:  Remote access and/or automatic firmware and configuration update parameters  VoIP configuration: SIP proxy, line settings (User IP, Password)  QoS parameters (e.g. traffic shaping)  13.1.2 Remote Management
MP252 Multimedia Home Gateway  13. Remote MP252 Management Version 3.4.0  187  June 2011 Remote management includes the following:  Firmware upgrade  Status and performance monitoring  Alarms, notifications, and logs 13.1.2.1 Firmware Upgrade Service providers require the ability to update MP252's firmware in the field (e.g. in case of maintenance releases or releases that support new required features). The process is required to be automatic, allowing mass update, which is robust and fail-safe. MP252's firmware is stored on the non-volatile flash memory. MP252's flash memory is capable of storing a recovery firmware that ensures a fail-safe operation (even if the user unplugs the power during the firmware burning process). MP252's firmware can be upgraded using one of the following mechanisms:  The new firmware can be "pushed" (uploaded) to MP252, using the MP252 Web interface  The new firmware can be "pulled" (downloaded) by MP252 from a remote HTTP, FTP, or TFTP server Figure 13-2: Firmware Upgrade Mechanism
MP252 Multimedia Home Gateway  188  Document #: LTRT-23504  User's Manual  The remote firmware download process can be triggered by one of the following:  MP252 checks for a new firmware upon MP252 restart   MP252 periodically checks for a new firmware  Manual trigger using CLI, TR-069, SNMP or Web   Note:  Unless forced, MP252 downloads and upgrades to the new firmware only if its version number is higher than the firmware version currently running on MP252. The version number is not taken from the image file name, but from the header of the image file.  13.1.2.2  Status and Performance Monitoring The ability to remotely monitor the status of MP252 is critical to the service provider, who wants to support users without having to send a technician on site (avoiding the "truck roll"). The service provider may want to know the current status of MP252 (e.g. is it registered to the SIP proxy, is the phone off-hook) or some statistical information (e.g. average packet loss during a call). MP252 maintains a set of status and performance information internally. This information (or parts of it) can be retrieved via the different management interfaces (e.g. Web, or TR-069). The table below describes the status and performance monitoring (statistical) information available in MP252. Table 13-2: Status and Performance Monitoring Parameters Group  Description VoIP   Current status information per line: 9 Phone state 9 Registration status 9 Source, codec and type of current call 9 Packet loss, jitter and delay of current call Network Connections   Current status information per interface: 9 Connection status 9 Allocated IP address 9 Received and transmitted packets System   Software version information  Hardware version information  System Up time
MP252 Multimedia Home Gateway  13. Remote MP252 Management Version 3.4.0  189  June 2011 13.1.2.3  Alarms, Notifications and Logging Instead of periodically polling MP252 to obtain its current status, the service provider may want MP252 to notify abnormal events or to send regular reports to a logging server. Both options are supported by MP252. The table below lists the relevant interfaces for alarms and notifications. Table 13-3: Notifications and Logged Events Group  Notifications and Logged Events VoIP  Notifications: Registration error or timeout  Logged Events: 9 End of call (Call Detail Record logging) 9 SIP messages logging (optional - for debugging) Network Connections  Notifications: Connection up / down Security  Logged Events: Security log (configurable) System  Notifications: 9 System restart 9 Firmware / configuration update  Logged Events: Debug-level logging (optional) Note that the terms Alarm and Notification represent the same thing. The difference between alarm/notification and logging is that an alarm is normally used to represent an abnormal event (e.g. registration error), while logged events can represent either regular events (e.g. end of call) or abnormal events.  The table below lists the event severity levels defined in MP252. Typically, events with severity of Error or Emergency are notified in addition to being logged. Table 13-4: Severity of Logged Events Severity  Description Debug  Debug-level messages. Notice  Normal but significant condition. Notices requiring attention at a later time. Non-error conditions that might require special handling. Error  Recoverable / temporary error condition. Emergency  System is unusable. The most severe messages that prevent continuation ofoperation, such as immediate system shutdown.    13.2  Enabling Remote Management You can access and manage MP252 not only from within the home network, but also from the Internet. This allows you to view or change settings while travelling. It also enables you to allow your ISP to change settings or help you troubleshoot functionality or communication issues from a remote location. Remote access to MP252 is blocked by default to ensure the security of your home network. However, remote access is supported by the following services, and you may use the 'Remote Access Configuration' screen to selectively enable these services if they are needed.
MP252 Multimedia Home Gateway  190  Document #: LTRT-23504  User's Manual   Notes:  • Telnet and Web-Management can be used to modify the settings of the firewall or to disable it. You can also change local IP addresses and other settings, making it difficult or impossible to access MP252 from the home network. Therefore, remote access to Telnet or HTTP services should be blocked and should only be permitted when absolutely necessary. • Encrypted remote administration is done using a secure SSL connection that requires an SSL certificate. When accessing MP252 for the first time using encrypted remote administration, you are prompted by your browser with a warning regarding certificate authentication. This is because MP252's SSL certificate is self generated. When encountering this message under these circumstances, ignore it and continue. It should be noted that even though this message appears, the self-generated certificate is safe, and provides you with a secure SSL connection. You can also assign a user-defined certificate to MP252.   ¾ To enable remote access to MP252 services: 1.  In the 'Advanced' screen, click the Remote Administration  icon; the 'Remote Administration' screen appears.

MP252 Multimedia Home Gateway  13. Remote MP252 Management Version 3.4.0  197  June 2011 13.4  Remote Configuration and Management Interfaces MP252 supports the following remote configuration and management interfaces:  Web server (GUI) over HTTP/HTTPS  TR-069 and TR-104  SNMP  Syslog  Firmware or configuration file download through HTTP/HTTPS and FTP/TFTP  CLI over Telnet/SSH The table below lists the possible operations over these different interfaces: Table 13-5: Operations per Configuration/Management Interface Operation  Web GUI  TR-069  SNMP  Syslog  File D/L  CLI Configuration Update  Yes Yes Yes  No Yes Yes Firmware Upgrade  Yes Yes Yes  No Yes Yes Status Monitoring  Yes Yes Yes No No Yes Debugging and Diagnostics  Yes  No  No Yes No Yes  Service providers can choose to combine several management interfaces, for example, automatic file download for configuration and firmware updates plus SNMP for alarms.    13.4.1  Embedded Web Server MP252 provides an embedded Web server with a rich Graphical User Interface (GUI). The Web server can be accessed from the local LAN interface (e.g. by the home user) or from the WAN interface (e.g. by the service provider support personnel). The Web GUI provides easy and intuitive configuration of all MP252 parameters (i.e., VoIP, network interfaces, security, QoS and advanced system settings). In addition, the Web GUI provides status monitoring pages, diagnostic pages and enabled firmware upgrade. Typically, service providers do not want to configure each MP252 manually and therefore, they do not use the Web server in live deployments. However, the Web server is still useful for:  Trying different configurations in the lab during the integration phases  Creating mass-configuration template files  Debugging special customer problems (by accessing the Web server from the WAN interface) Since the Web server allows all configuration and management operations, it is important to protect it. The following security measures are available:  The Web server is user and password protected. Several users can be defined. A special user with limited-access (only to the 'Quick Setup' screen) can be defined.  The access to the Web server can be blocked from the WAN and/or LAN interfaces.  Access to the Web server can be limited to specific IP addresses.   Secured HTTP (HTTPS) is supported. It is possible to enable HTTPS-only, if required.
MP252 Multimedia Home Gateway  198  Document #: LTRT-23504  User's Manual   The HTTP and/or HTTPS port can be modified (from the default 80 and 8080).  13.4.2  TR-069 and TR-104 CPE WAN Management Protocol TR-069 is a WAN management protocol intended for communication between Customer Premise Equipment (CPE) or residential devices (such as MP252), and an Auto-Configuration Server (ACS), residing on the service provider's side. It defines a mechanism that encompasses secure auto configuration of CPE, and also incorporates other CPE management functions into a common framework. In simpler terms, TR-069 is a protocol that enables remote server management of theMP252. Such a protocol is useful, for example, for remotely and securely controlling MP252 by the CPE provider. The standard is published by the DSL Forum. TR-069 runs over SOAP/HTTP and enables device configuration, management (including firmware upgrade), and status monitoring. TR-104 is an extension of TR-069 for VoIP configuration and monitoring. The TR standards are published by the DSL forum:  TR-069: http://www.broadband-forum.org/technical/download/TR-069.pdf   TR-104: http://www.broadband-forum.org/technical/download/TR-104.pdf  Figure 13-12: TR-069 CPE WAN Management Protocol  The TR-069 protocol allows an ACS to provision a CPE or collection of CPE based on a variety of criteria. The provisioning mechanism includes specific provisioning parameters and a general mechanism for adding vendor-specific provisioning capabilities as needed. The provisioning mechanism allows CPE provisioning at the time of initial connection to the broadband access network, and the ability to re-provision at any subsequent time. This includes support for asynchronous ACS-initiated re-provisioning of CPE. TR-069 defines several Remote Procedure Call (RPC) methods, as well as a large number of parameters, which may be set or read. Some of these methods and parameters are defined as mandatory.    Notes:  • MP252 was tested for interoperability with two ACS vendors – Motive and FriendlyTR69. Working with other ACS types may require specific interoperability effort. • The parameter values in the subsequent tables are sample values only taken from an ACS.

MP252 contains an embedded SNMP agent and supports SNMPv1, SNMPv2 and partially supports SNMPv3. For monitoring of the network interfaces, the standard SNMP MIB-II (RFC 1213) is supported. For more options, a proprietary MIB, AC-MP20X-MIB includes the following sections:  acMP20xConfig: for changing MP252's configuration  acMP20xStatus: for monitoring MP252's status The figure below shows the SNMP network architecture: Figure 13-13: SNMP Network Architecture   13.4.3.1  Enabling SNMP in the Web Interface Simple Network Management Protocol (SNMP) enables Network Management Systems (NMSs) to remotely configure and monitor your MP252. Your ISP may use SNMP to identify and resolve technical problems. Technical information regarding the properties of MP252's SNMP agent should be provided by your ISP. The procedure below describes how to configure the SNMP agent embedded on  the MP252. ¾ To configure MP252's SNMP agent: 1.  In the 'Advanced' screen, click the Simple Network Management Protocol (SNMP)  icon; the 'Simple Network Management Protocol (SNMP)' screen appears.
MP252 Multimedia Home Gateway  13. Remote MP252 Management Version 3.4.0  213  June 2011 Figure 13-14: Simple Network Management Protocol (SNMP) Screen   2.  Select the 'Enabled' check box to enable SNMP. 3.  Select the ‘Allow Incoming WAN Access to SNMP’ check box to allow access to MP252's SNMP agent over the Internet. 4.  In the ‘Read-Only Community Names’ and ‘Read-Write Community Names’    fields, enter the SNMP community strings. These strings are passwords used in SNMP messages between the management system and MP252. A read-only community allows the manager to monitor MP252. A read-write community allows the manager to monitor and configure MP252. 5.  From the ‘Trusted Pair’ drop-down list, enter the IP address, or subnet of addresses that identify which remote management stations are allowed to perform SNMP operations on MP252. 6.  Under the SNMP Traps group, select the ‘Enabled’ check box to allow MP252 to send messages (traps) to a remote management station to notify the manager about the occurrence of important events or serious conditions.   • Version: SNMP version - SNMP v1 or SNMP v2c traps. • Destination: remote management station's IP address. • Community: community name that is associated with the trap messages. 7.  Click OK to save your settings.   13.4.3.2  Configuring MP252 via SNMP The acMP20xConfig MIB section is structured in a similar hierarchy as MP252's Web GUI. Each parameter in the MIB has a matching parameter in the Web GUI and a matching parameter in the gateway’s configuration file. The MIB file defines the valid range and the default value for each parameter. Typically, the customer integrates the MP20x MIB into the customer's Network Management System (NMS) to automate the configuration process.  Note:  A special MIB object is defined to allow MP252 firmware upgrade triggered by SNMP. The object acMP20xRemoteUpdate triggers a remote upgrade from the SNMP-configured URL.
MP252 Multimedia Home Gateway  214  Document #: LTRT-23504  User's Manual  13.4.3.3  Status Monitoring of System and Network Interfaces via SNMP SMNP can be used to monitor the status of MP252. Status monitoring of the system and network interfaces can be done via the standard MIB-II (iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1)). The following table shows some of the information elements available via MIB-II: Table 13-17: Table  3-13: Information Elements Available via MIB-II Section  Available Information system  Description  Version Information  Up-time interfaces Information per network interface:  Description  Type  Speed  MAC address  Traffic statistics  Errors ip Assigned IP addresses and IP-related parameters icmp, udp, tcp Transport-protocol specific statistical information ifMIB Information about network interfaces per RFC 2233   13.4.3.4  Security Concerns and Measures Since SNMP allows write-access to configuration parameters, it is important to protect this interface. The following security measures are available:  A community string (password) can be defined for read-only access and for read/write access.  It is possible to limit access to SNMP to a trusted peer (single IP address or a range of addresses).  SNMPv3 provides an significant security improvement over SNMPv1/2. Version 2.8.0 will support SNMPv3 and will allow the service provider to configure SNMPv3 security parameters.  SNMP traffic can be allowed over an IPSec secured connection – check availability with AudioCodes.
MP252 Multimedia Home Gateway  13. Remote MP252 Management Version 3.4.0  215  June 2011 13.4.4 Syslog Syslog is a standard protocol for reporting and logging of messages over IP network and is defined by RFC 3164. MP252 enables the service provider to configure a Syslog server and a severity level above which errors are sent to the server. Typically, only error-level messages should be sent to the Syslog server (in order not to flood it with irrelevant debug-level information). For debugging, it is possible to temporarily allow logging for debug-level messages (e.g. for SIP messages). Many free Syslog servers exist, including Kiwi Syslog Daemon' (http://www.kiwisyslog.co'm http://www.kiwisyslog.com).   Note:  Since Syslog is used only to output messages from MP252, it does not contain any security concerns.  13.4.5  Automatic File Download A practical, straight-forward and easy to implement method for mass configuration and firmware update is automatic file download from a remote file server (via HTTP, FTP, or TFTP). This method is used by many service providers.  13.4.5.1 Firmware File Download MP252's firmware files contain information about the target product type and the firmware version information.  13.4.5.2  Configuration File Download MP252 supports two configuration file formats, a *.conf file and an *.ini file. Both files define the same parameters, but in a different format; the *.conf file has a hierarchical tree-like structure and the *.ini file is "flat" (defining the full path for each parameter). As with the firmware file, the configuration file can be “pushed” to MP252 via the Web server or “pulled” by MP252 from a remote server. This section refers only to the second option. When MP252 downloads a file from a remote server, it performs the following actions:  Decrypts the file, if it is encrypted.  Checks that the file version is later than the current configuration file version (if it is not later, the new configuration is not used).  Checks the software version with which the configuration file was created (if the file was created with a later software version, it is not used).
MP252 Multimedia Home Gateway  216  Document #: LTRT-23504  User's Manual   Merges the configuration file with the current configuration: • Parameters that appear in the new file are modified or added • Parameters that do not appear in the new file remain in their existing value   Notes:  • It is recommended that the configuration file (that is downloaded from the network), contains only the small subset of parameters that the service provider needs to update remotely. • To create the configuration file, it is recommended to use a MP252 that is restored to factory settings, modify the required parameters using the Web GUI, and then upload the configuration file from MP252 with the option to get only the modified configuration fields enabled.   13.4.5.3  Security Concerns and Measures The main security hazard in automatic file download is that a hacker can force MP252 to download a file from the hacker's server instead of the service provider’s legitimate server. Another concern is exposing information such as the SIP proxy IP address and user and password information in the configuration file (if the hacker is sniffing the network). The following security measures are available to prevent this:  The configuration file can be encrypted using 3DES with pre-configured key. This prevents the user from learning the format of the file and obtaining information from it.  HTTPS can be used to further encrypt the transport.  HTTPS certificates can be used to allow MP252 to authenticate the server and also to prevent the user from acquiring the file from the server. 13.4.6 Telnet CLI MP252 features a Command Line Interface (CLI) over Telnet. The CLI enables the service provider to manage MP252 (e.g. reboot, force a firmware upgrade), to obtain information about the status of the device (e.g. VoIP calls, network interfaces, version information), to change the configuration and to perform different debugging tasks (e.g. enable debug logging, enable packet recording). Typically, the CLI interface is only used for debugging and diagnostics, since it does not allow mass configuration and monitoring. Since the CLI allows all configuration and management operations, it is important to protect it. The following security measures are available:  The CLI is user and password protected (same as the Web).  Telnet access can be blocked from the WAN and/or LAN interfaces.  It is possible to limit Telnet access to specific IP addresses.  Future versions will support SSH.
Version 3.4.0  217  July 2011 MP252 Multimedia Home Gateway  14. Security 14 Security MP252's security suite includes comprehensive and robust security services: Stateful Packet Inspection Firewall, user authentication protocols and password protection mechanisms. These features together allow users to connect their computers to the Internet and simultaneously be protected from the security threats of the Internet. The firewall, which is the cornerstone of your MP252's security suite, has been exclusively tailored to the needs of the residential/office user and has been pre-configured to provide optimum security. Figure 14-1: Firewall in Action  MP252 firewall provides both the security and flexibility that home and office users seek. It provides a managed, professional level of network security while enabling the safe use of interactive applications, such as Internet gaming and video-conferencing. Additional features, including surfing restrictions and access control, can also be easily configured locally by the user through a user-friendly Web-based interface, or remotely by a service provider. MP252 firewall supports advanced filtering, designed to allow comprehensive control over the firewall's behavior. You can define specific input and output rules, control the order of logically similar sets of rules and make a distinction between rules that apply to WAN and LAN network devices. The Web-based management screens in the Security section feature the following:  The 'General' screen allows you to choose the security level for the firewall (see' General Security Level Settings' on page 218).  The 'Access Control' screen can be used to restrict access from the home network to the Internet (see 'Local Servers (Port Forwarding)' on page 221).  The 'Port Forwarding' screen can be used to enable access from the Internet to specified services provided by computers in the home network and special Internet applications (see 'Port Forwarding' on page 221).  The 'DMZ Host' screen allows you to configure a LAN host to receive all traffic arriving at your MP252, which does not belong to a known session (see' Port Triggering' on page 227).  The 'Port Triggering' screen allows you to define port triggering entries, to dynamically open the firewall for some protocols or ports. (see 'Remote Administration' on page 253).  The 'Website Restrictions' allows you to block LAN access to a certain host or web site on the Internet (see 'Website Restrictions' on page 229).  'Advanced Filtering' allows you to implicitly control the firewall setting and rules (see 'Advanced Filtering' on page 236).
MP252 Multimedia Home Gateway  218  Document #: LTRT-23504  User's Manual   'Security Log' allows you to view and configure the firewall Log (see Security Log).  14.1  General Security Level Settings Use the 'Security Settings' screen to configure the MP252's basic security settings. Figure 14-2: General Security Level Settings  The firewall regulates the flow of data between the home network and the Internet. Both incoming and outgoing data are inspected and then either accepted (allowed to pass through MP252) or rejected (barred from passing through MP252) according to a flexible and configurable set of rules. These rules are designed to prevent unwanted intrusions from the outside, while allowing home users access to the Internet services that they require. The firewall rules specify what types of services available on the Internet may be accessed from the home network and what types of services available in the home network may be accessed from the Internet. Each request for a service that the firewall receives, whether originating in the Internet or from a computer in the home network, is checked against the set of firewall rules to determine whether the request should be allowed to pass through the firewall. If the request is permitted to pass, then all subsequent data associated with this request (a "session") are also allowed to pass, regardless of its direction. For example, when you point your Web browser to a Web page on the Internet, a request is sent out to the Internet for this page. When the request reaches MP252, the firewall identifies the request type and origin--HTTP and a specific PC in your home network, in this case. Unless you have configured access control to block requests of this type from this computer, the firewall allows this request to pass out onto the Internet (see 'WAN PPPoE' on page 173 for more on setting access controls). When the Web page is returned from the Web server the firewall associates it with this session and allows it to pass, regardless of whether HTTP access from the Internet to the home network is blocked or permitted.
MP252 Multimedia Home Gateway  14. Security Version 3.4.0  219  June 2011 Note that it is the origin of the request, not subsequent responses to this request, that determines whether a session can be established or not. You can choose from among three pre-defined security levels for MP252: Minimum, Typical, and Maximum (the default setting). The table below summarizes the behavior of MP252 for each of the three security levels. Table 14-1: Behavior for the Three Security Levels Security Level  Requests Originating  in the WAN  (Incoming Traffic) Requests  Originating  in the LAN  (Outgoing Traffic) Maximum Security (Default) Blocked: No access to home network from Internet, except as configured in the Local Servers, DMZ host and Remote Access screens Limited: Only commonly- used services, such as Web- browsing and e-mail, are permitted Typical Security  Blocked: No access to home network from Internet, except as configured in the Local Servers, DMZ host and Remote Access screens Unrestricted: All services are permitted, except as configured in the Access Control screen Minimum Security  Unrestricted: Permits full access from Internet to home network; all connection attempts permitted. Unrestricted: All services are permitted, except as configured in the Access Control screen These services include Telnet, FTP, HTTP, HTTPS, DNS, IMAP, POP3 and SMTP.  The list of allowed services at 'Maximum Security' mode can be edited in the screen' 'Access Contro'l on page 220'. Some applications (such as some Internet messengers and Peer-To-Peer client applications) tend to use these ports if they cannot connect with their own default ports. When applying this behaviour, these applications are not blocked outbound, even at Maximum Security Level.
MP252 Multimedia Home Gateway  220  Document #: LTRT-23504  User's Manual  ¾ To configure MP252's security settings: (See the figure 'General Security Level Settings') 1.  Choose from among the three predefined security levels described in the table above. 'Maximum Security' is the default setting. Using the Minimum Security setting may expose the home network to significant security risks, and thus should only be used, when necessary, for short periods of time. 2.  Check the 'Block IP Fragments' check box to protect your home network from a common type of hacker attack that could make use of fragmented data packets to sabotage your home network. Note that some UDP-based services make legitimate use of IP fragments. You need to allow IP fragments to pass into the home network to make use of these select services. 3.  In the 'TCP Session timeout' field, enter the time-to-live (TTL) in units of seconds for TCP sessions. The valid range is 1 to 3600 hours (default is an hour). 4.  Click OK to save the changes.  14.2 Access Control You may want to block specific computers within the home network (or even the whole network) from accessing certain services on the Internet. For example, you may want to prohibit one computer from surfing the Web, another computer from transferring files using FTP, and the whole network from receiving incoming e-mail. Access Control defines restrictions on the types of requests that may pass from the home network out to the Internet, and thus may block traffic flowing in both directions. In the e-mail example given above, you may prevent computers in the home network from receiving e-mail by blocking their outgoing requests to POP3 servers on the Internet. There are services you should consider blocking, such as popular game and file sharing servers. For example, to ensure that your employees do not put your business at risk from illegally traded copyright files, you may want to block several popular P2P and file sharing applications. ¾ To view and allow/restrict these services: 1.  From the menu bar, click the Security menu, and in the screen 'Security', click the Access Control tab; the screen 'Access Control' opens. Figure 14-3: Access Control  2.  Click the New  icon; the screen 'Add Access Control Rule' opens (see the figure below). Figure 14-4: Add Access Control Rule

The parameter 'Address' enables you to specify the computer or group of computers for which you would like to apply the access control rule. You can select between any or a specific computer address in your LAN. If you choose the 'Specify Address' option, the screen refreshes, and an 'Add' link appears. Click it to specify a computer address. Specify an address by creating a 'Network Object'. 4.  The parameter 'Protocol' lets you select or specify the type of protocol to be used. In addition to the list of popular protocols it provides, you may also choose any or a specific protocol. If you choose option 'Specify Protocol', the screen refreshes and an 'Add' link appears. Click it to specify a protocol address.  5.  The parameter 'Schedule' allows you to define the time period during which this rule takes effect. You can select between 'Always' or a specific schedule. If you choose the option 'Specify Schedule', the screen refreshes and an 'Add' link appears. Click it to specify a schedule.  6.  Click OK to save your settings; the 'Access Control' screen displays a summary of the rule that you just added. Click the Edit   icon to edit the access control rule for the service; the screen 'Edit Service' opens. 7.  Select the network group to which you would like to apply the rule and the schedule during which the rule takes effect. 8.  Click OK to save your changes and return to the 'Access Control' screen. You can disable an access control rule and make the service available without having to remove the service from 'Access Control'. This can be useful when making the service only temporarily available and when expecting to reinstate the restriction in the future.  To temporarily disable rule, clear the check box adjacent to the service name.  To reinstate the restriction at a later time, recheck it.  To remove a rule, click the Remove  icon for the service; the service is removed from 'Access Control'.   Note:  When Web Filtering is enabled, HTTP services cannot be blocked by Access Control.   14.3 Port Forwarding By default, MP252 blocks all external users from connecting to or communicating with your network. Therefore, the system is safe from hackers who may try to intrude on the network and damage it. However, you may want to expose your network to the Internet in certain limited and controlled ways to enable some applications to work from the LAN (game, voice and chat applications, for example) and to enable Internet access to servers in the home network. The Port Forwarding feature supports both of these functionalities.
MP252 Multimedia Home Gateway  222  Document #: LTRT-23504  User's Manual  The 'Port Forwarding' screen lets you define the applications that require special handling by MP252. You must select the application's protocol and the local IP address of the computer using or providing the service. If required, you can add new protocols in addition to the most common ones provided by MP252. For example, to use an FTP application on one of your PCs, select 'FTP' from the list and enter the local IP address or host name of the designated computer; all FTP-related data arriving at MP252 from the Internet is then forwarded to the specified computer. Similarly, to grant Internet users access to servers inside your home network, you must identify each service that you want to provide and the PC that provides it. For example, to host a Web server inside the home network you must select 'HTTP' from the list of protocols and enter the local IP address or host name of the computer that hosts the Web server. When an Internet user points her browser to the external IP address of MP252, it forwards the incoming HTTP request to the computer that is hosting the Web server. Additionally, port forwarding enables you to redirect traffic to a different port instead of the one to which it was designated. If for example you have a Web server running on your PC on port 8080 and you want to grant access to this server to anyone who accesses MP252 via HTTP, do the following:  Define a port forwarding rule for the HTTP service, with the PC's IP or host name.  Specify 8080 in the field 'Forward to Port'. All incoming HTTP traffic is now forwarded to the PC running the Web server on port 8080. When setting a port forwarding service, you must ensure that the port is not already in use by another application, which may stop functioning. A common example is when using SIP signaling in Voice over IP - the port used by MP252's VoIP application (5060) is the same port on which port forwarding is set for LAN SIP agents.   Note:  Some applications, such as FTP, TFTP, PPTP and H323, require the support of special specific Application Level Gateway (ALG) modules in order to work inside the home network. Data packets associated with these applications contain information that allows them to be routed correctly. An ALG is needed to handle these packets and ensure that they reach their intended destinations. MP252 is equipped with a robust list of ALG modules in order to enable maximum functionality in the home network. The ALG is automatically assigned based on the destination port.
MP252 Multimedia Home Gateway  14. Security Version 3.4.0  223  June 2011 ¾ To add a new port forwarding service : 1.  From the menu bar, click the Security menu, and in the screen 'Security', click the Port Forwarding tab; the screen 'Port Forwarding' opens.  Figure 14-5: Port Forwarding Screen  2.

Select the 'Specify Public IP Address' check box if you want to apply this rule on MP252’s non-default IP address defined in the ‘NAT’ screen (see Section 14.7 on page 232). Enter the additional external IP address in the 'Public IP Address' field. Figure 14-8: Specifying Public IP Address  b.  By default, MP252 forwards traffic to the same port as the incoming port. If you wish to redirect traffic to a different port, then from the 'Forward to Port' drop-down list, select the 'Specify', and then enter the port number in the field provided. c.  By default, the rule is always active. However, you can select a schedule rule that defines the time during which the rule may be active. From the 'Schedule' drop-down list, select a defined Schedule rule (defined in Section 4.5.1 on page 43) or define a new one quickly by selecting 'User Defined'. 6.  Click OK to save changes. You can disable a port forwarding rule to make a service unavailable without having to remove the rule from the screen 'Port Forwarding'. This can be useful when making the service temporarily unavailable and when expecting to reinstate it in the future.

MP252 Multimedia Home Gateway  226  Document #: LTRT-23504  User's Manual  14.4 DMZ Host The DMZ (Demilitarized) Host feature allows one local computer to be exposed to the Internet. Designate a DMZ host to:  Use a special-purpose Internet service, such as an on-line game or video-conferencing program, that is not present in the Local Servers list and for which no port range information is available.  To expose one computer to all services, without restriction, irrespective of security. Warning: A DMZ host is not protected by the firewall and may be vulnerable to attack. Designating a DMZ host may also put other computers in the home network at risk. When designating a DMZ host, you must consider the security implications and protect it if necessary. An incoming request for access to a service in the home network, such as a Web-server, is fielded by MP252. MP252 forwards this request to the DMZ host (if one is designated) unless the service is being provided by another PC in the home network (assigned in Local Servers), in which case that PC receives the request instead. ¾ To designate a local computer as a DMZ Host: 1.  From the menu bar, click the Security menu, and in the screen 'Security', click the DMZ Host tab; the screen 'DMZ Host' opens. Figure 14-10: DMZ Host  2.  Enter the local IP address of the computer to be designated as a DMZ host. Note that only one LAN computer can be a DMZ host at any time. 3.  Click OK to save your changes and return to the screen 'DMZ Host'. You can disable the DMZ host so that it does not fully exposed to the Internet, but keep its IP address recorded on the 'DMZ Host' screen. This may be useful if you wish to disable the DMZ host but expect that you may want to enable it again in the future.  To disable the DMZ host so that it is not fully exposed to the Internet, clear the check-box next to the DMZ IP designation and click OK.  To re-enable the DMZ host later, recheck the check-box.
MP252 Multimedia Home Gateway  14. Security Version 3.4.0  227  June 2011 14.5 Port Triggering Port triggering can be used for dynamic port forwarding configuration. By setting port triggering rules, you can allow inbound traffic to arrive at a specific LAN host, using ports different than those used for the outbound traffic. This is called port triggering since the outbound traffic triggers to which ports inbound traffic is directed. For example, consider a gaming server that is accessed using UDP protocol on port 222. The gaming server responds by connecting the user using UDP on port 333 when starting gaming sessions. In such a case you must use port triggering, since this scenario conflicts with the following default firewall settings:  The firewall blocks inbound traffic, by default.  The server replies to MP252's IP, and the connection is not sent back to your host, since it is not part of a session. To solve this, you need to define a Port Triggering entry, which allows inbound traffic on UDP port 333, only after a LAN host generated traffic to UDP port 222. This results in accepting the inbound traffic from the gaming server and sending it back to the LAN Host which originated the outgoing traffic to UDP port 222. ¾ To view port triggering settings: 1.  From the menu bar, click the Security menu, and in the screen 'Security', click the Port Triggering tab; the screen 'Port Triggering' opens. The screen lists all port triggering entries.

When enabling multiple computers on your network to access the Internet using a fixed number of public IP addresses, you can statically define which LAN IP address will be translated to which NAT IP address and/or ports. By default, MP252 operates in NAPT routing mode. However, you can control your network translation by defining static NAT/NAPT rules. Such rules map LAN computers to NAT IP addresses. The NAT/NAPT mechanism is useful for managing Internet usage in your LAN, or complying with various application demands. For example, you can assign your primary LAN computer with a single NAT IP address, in order to assure its permanent connection to the Internet. Another example is when an application server with which you wish to connect, such as a security server, requires that packets have a specific IP address – you can define a NAT rule for that address.

Version 3.4.0  243  July 2011 MP252 Multimedia Home Gateway  15. Advanced Networking Features 15 Advanced Networking Features This chapter describes various advanced networking features such as DHCP. 15.1  IP Address Distribution The MP252's Dynamic Host Configuration Protocol (DHCP) server makes it possible to easily add computers that are configured as DHCP clients to the home network. It provides a mechanism for allocating IP addresses and delivering network configuration parameters to such hosts. MP252's default DHCP server is the LAN bridge. A client (host) sends out a broadcast message on the LAN requesting an IP address for itself. The DHCP server then checks its list of available addresses and leases a local IP address to the host for a specific period of time and simultaneously designates this IP address as `taken'. At this point, the host is configured with an IP address for the duration of the lease. The host can choose to renew an expiring lease or let it expire. If it chooses to renew a lease then it also receives current information about network services, as it did with the original lease, allowing it to update its network configurations to reject any changes that may have occurred since it first connected to the network. If the host wishes to terminate a lease before its expiration it can send a release message to the DHCP server, which then makes the IP address available for use by others. The MP252 embedded DHCP server provides the following features:  Displays a list of all DHCP host devices connected to MP252  Defines the range of IP addresses that can be allocated to the LAN  Defines the length of time for which dynamic IP addresses are allocated  Provides the above configurations for each LAN device and can be configured and enabled / disabled separately for each LAN device  Can assign a static lease to a LAN PC so that it receives the same IP address each time it connects to the network even if this IP address is within the range of addresses that the DHCP server may assign to other computers  Provides the DNS server with the host name and IP address of each PC that is connected to the LAN In addition, MP252 can act as a DHCP relay, escalating DHCP responsibilities to a WAN DHCP server. In this case, MP252 acts merely as a router, while its LAN hosts receives their IP addresses from an external DHCP server on the WAN. With MP252's optional Zero Configuration Technology feature, the IP Auto Detection method detects statically-defined IP addresses in addition to MP252's DHCP clients. It learns all the IP addresses on the LAN and integrates the collected information with the database of the DHCP server. This allows the DHCP server to issue valid leases, thus avoiding conflicting IP addresses used by other computers in the network.
MP252 Multimedia Home Gateway  244  Document #: LTRT-23504  User's Manual  ¾ To view services currently provided by the DHCP server:  In the 'Advanced' screen, click the IP Address Distribution    icon; the 'IP Address Distribution' screen appears.  Figure 15-1: DHCP Server Summary    Note:  If the 'Service' column displays “Disabled”, then DHCP services are not being provided to hosts connected to the network through that MP252 interface. This means that MP252 does not assign IP addresses to these computers, which is useful if you wish to work with static IP addresses only.
MP252 Multimedia Home Gateway  15. Advanced Networking Features Version 3.4.0  245  June 2011 15.1.1  DHCP Server Parameters The procedure below describes how to edit a service provided by the DHCP server. ¾ To edit the DHCP server settings for a device: 1.

Figure 15-2: DHCP Settings Screen  2.  From the 'IP Address Distribution' drop-down list, select whether to disable the MP252 DHCP server, or enable DHCP (MP252 serves as a DHCP server or DHCP relay). 3.  In the ‘Start IP Address’ and ‘End IP Address’ fields, define the IP address range. This determines the number of hosts that may be connected to the network in this subnet. The 'Start IP Address' field specifies the first IP address that may be assigned in this subnet; the 'End IP Address' field specifies the last IP address in the range. 4.  In the ‘Subnet Mask’ field, define the subnet to which an IP address belongs (e.g., 255.255.0.0). 5.  In the ‘Lease Time in Minutes’ field, define the time for which each device is assigned an IP address by the DHCP server when it connects to the network. When the lease expires, the server determines if the computer has disconnected from the network. If it has, then the server may reassign this IP address to a newly-connected computer. This feature ensures that IP addresses that are not in use become available for other computers on the network. 6.  Select the ‘Provide Host Name If Not Specified by Client’ check box to enable the MP252 to assign clients a default name if they do not have a host name. 7.  Click OK.

The DNS server does not require configuration. However, you can view the list of computers known by the DNS, edit the host names or IP addresses of computers in the list, or manually add a new computer to the list. DNS provides a service that translates domain names into IP addresses and vice versa. MP252's DNS server is an auto-learning DNS, which means that when a new computer is connected to the network, the DNS server learns its name and automatically adds it to the DNS table. Other network users may immediately communicate with this computer using either its name or its IP address. The MP252 DNS server also provides the following functionalities:  Shares a common database of domain names and IP addresses with the DHCP server.  Supports multiple subnets within the LAN simultaneously.  Automatically appends a domain name to unqualified names.  Allows new domain names to be added to the database using MP252's Web interface.  Permits a computer to have multiple host names.  Permits a host name to have multiple IPs (needed if a host has multiple network cards).

Click OK to save your changes. ¾ To remove a host from the DNS table:  Click the Remove   icon corresponding to the host that you want to delete; the entry is removed from the table. 15.3 Dynamic DNS The Dynamic DNS (DDNS) feature allows you to alias a dynamic IP address to a static hostname, allowing your computer to be more easily accessible from various locations on the Internet. Typically, when you connect to the Internet, your ITSP assigns an unused IP address from a pool of IP addresses, and this address is used only for the duration of a specific connection. Dynamically assigning addresses extends the usable pool of available IP addresses, whilst maintaining a constant domain name. When using the DDNS service, each time the IP address provided by your ITSP changes, the DNS database changes accordingly to reflect the change. In this way, even though your IP address changes often, your domain name remains constant and accessible.
MP252 Multimedia Home Gateway  15. Advanced Networking Features Version 3.4.0  251  June 2011 To be able to use the Dynamic DNS (DDNS) feature, you must first open a free DDNS account at http://www.dyndns.org/account/create.html. When applying for an account, you need to specify a user name and password. Have them readily available when customizing MP252's DDNS support. For detailed information on DDNS, see http://www.dyndns.org. ¾ To open a dynamic DNS account: 1.

In the ‘Gateway’ field, enter the MP252's IP address. 6.  In the ‘Metric’ field, enter the measurement of the preference of a route. Typically, the lowest metric is the most preferred route. If multiple routes exist to a given destination network, the route with the lowest metric is used. 7.  Click OK to save your settings.   15.4.2 Routing Protocols MP252 supports IGMP multicasting, which allows hosts connected to a network to be updated whenever an important change occurs in the network. A multicast is simply a message that is sent simultaneously to a pre-defined group of recipients. When you join a multicast group you receive all messages addressed to the group, similar to an e-mail message sent to a mailing list. IGMP multicasting enables UPnP capabilities over wireless networks and may also be useful when connected to the Internet through a router. When an application running on a computer in the home network sends out a request to join a multicast group, MP252 intercepts and processes the request. If MP252 is set to 'Minimum Security', no further action is required. However, if MP252 is set to 'Typical Security' or 'Maximum Security', you must add the group's IP address to MP252's 'Multicast Groups' screen. This allows incoming messages addressed to the group to pass through the MP252 firewall and on to the correct LAN computer. ¾ To configure routing protocols: 1.  In the 'Advanced' screen, under the Internet Group Management Protocol (IGMP) group, do the following:  a.  Select the 'Enabled' check box to enable IGMP multicasting.  b.  Select the ‘IGMP Fast Leave' check box if you want MP252 to stop forwarding traffic to a host that is the only subscriber, immediately upon request (without query delay). c.  Select the 'IGMP Multicast to Unicast' check box to enable MP252 to convert the incoming multicast data stream into unicast format to route it to the specific LAN host that requested the data. In this way, MP252 prevents flooding the rest of the LAN hosts with irrelevant multicast traffic. 2.  Under the Packet Streaming Engine group, from the ‘Software Acceleration’ drop-down list, select the packet flow speed:  • None: Packet Streaming Engine (PSE) is disabled • Medium: PSE is active (recommended) • High: PSE traffic is prioritized over other traffic 3.  Click OK.  15.5 PPPoE Relay PPPoE relay enables MP252 to relay packets on PPPoE connections while keeping its designated functionality for any additional connections.  ¾ To enable PPPoE relay:

Version 3.4.0  257  July 2011 MP252 Multimedia Home Gateway  16. Home Media 16 Home Media 16.1  Universal Plug and Play Universal Plug-and-Play (UPnP) is a networking architecture that provides compatibility among networking equipment, software, and peripherals. UPnP-enabled products can seamlessly connect and communicate with other UPnP-enabled devices without the need for user configuration, centralized servers, or product-specific device drivers. This technology leverages existing standards and technologies, including TCP/IP, HTTP 1.1 and XML, facilitating the incorporation of UPnP capabilities into a wide range of networked products for the home.  UPnP technologies are rapidly adopted and integrated into widely-used consumer products such as Windows XP. Therefore it is critical that today's Residential Gateways be UPnP-compliant. Your MP252 is at the forefront of this development, offering a complete software platform for UPnP devices. This means that any UPnP-enabled control point (client) can dynamically join the network, obtain an IP address and exchange information about its capabilities and those of other computers on the network. They can subsequently communicate with each other directly, thereby further enabling peer-to-peer networking. And this all happens automatically, providing a truly zero-configuration network. 16.1.1  Enabling UPnP on MP252 The procedure below describes how to enable the UPnP feature on MP252. ¾ To enable UPnP: 1.  In the 'Advanced' screen, click the Universal Plug and Play   icon; the 'Universal Plug and Play' screen appears. Figure 16-1: Advanced - Universal Plug n Play  2.  Select the ‘Allow Other Network Users to Control MP252’s Network Features’ to enable the UPnP feature. This allows you to define UPnP services on any of the LAN hosts. 3.  Select the ‘Enable Automatic Cleanup of Old Unused UPnP Services’ to enable automatic cleanup of invalid rules. This feature checks the validity of all UPnP services every five minutes, and removes old and obsolete services, unless a user-defined rule depends on them. 4.  From the ‘WAN Connection Publication’ drop-down list, select which WAN information is published by MP252. By default, MP252 publishes only its main WAN connection, which is controllable by UPnP entities. However, you may select the 'Publish All WAN Connections' option if you wish to grant UPnP control over all of MP252’s WAN connections.

MP252 Multimedia Home Gateway  17. Add-On Servers and Disk Management Version 3.4.0  275  June 2011 17.2.3 RAID Management MP252 supports Redundant Array of Independent Disks (RAID) on storage devices connected to it by USB or by FireWire. A RAID device is a logical device that has physical devices underlying it. These physical devices are disk partitions. The supported RAID levels are:   Level 0 – Provides data striping, or spreading out blocks of each file across multiple disk drives, but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.  Level 1 – Provides disk mirroring. This is a technique in which data is written to two duplicate disks simultaneously, providing data redundancy. This method improves performance and delivers fault tolerance.  Level 5 – With a minimum of three disks, this level provides data striping and utilizes one disk for backup information, which enables it to restore any other disk in the array. Before creating the RAID device, you must create disk partitions (as described previously) on the different disk drives. Each RAID device can have multiple underlying devices (partitions). When using RAID1, it is recommended that these partitions be of the same size to avoid disk-space loss due to mirroring. A disk partition configured with RAID can no longer be managed as a regular partition, but only be controlled by the RAID device. From the moment RAID is configured, it is the RAID device that can be shared, scanned, formatted and mounted as a regular partition. 17.2.3.1 Creating a RAID Device The procedure below describes how to create a RAID device. ¾ To create a RAID device: 1.  In the RAID Devices table in the ‘Disk Management’ screen, click the Add RAID Device link; the 'RAID Properties' screen appears: Figure 17-18: RAID Properties Screen  2.  From the ‘RAID Level’ drop-down list, select the RAID level (RAID0, RAID1 or RAID5). 3.  In the 'Mount Point' field, enter a name for the mount point of the RAID device. 4.  Choose the underlying devices (your pre-configured partitions) in the next drop-down lists. For RAID1 you may choose only one device and later add another one.

Select the format type, and then click Next; the 'Partition Summary' screen displays a summary of the chosen device properties.  Figure 17-21: Partition Summary Screen  8.  Click the Finish button to execute the RAID device creation. As soon as a RAID device is created, its formatting begins. If the device is RAID1 and has two underlying devices, its re-synchronization process (partition mirroring) begins simultaneously. During re-synchronization the RAID device is fully usable and can be mounted and used.
MP252 Multimedia Home Gateway  17. Add-On Servers and Disk Management Version 3.4.0  277  June 2011 The figure below depicts a successful configuration of two RAID devices as they appear in the  Raid Devices table in the 'File Server' screen. The first is RAID0, consisting of two underlying partitions (one on each disk), and the second is RAID1, consisting of another set of underlying partitions. Note that the RAID0 total space is the sum of the two partitions, while the RAID1 total space is the size of one partition (due to mirroring). Figure 17-22: Added RAID Devices  17.2.3.2  Using a RAID Device When RAID is configured over the existing partitions, these partitions are no longer independent. It is therefore necessary that you update the location of the system storage area: 1.  In the 'Disk Management' screen, verify that the 'Automatically Create System Storage Area' check box is selected. If you wish to define the system storage area manually, clear the check box and enter the name of the designated mount point. 2.  Click OK to save the settings. 17.2.3.3  Maintaining a RAID Device A RAID device differs from a regular partition by not being part of a physical disk. It therefore resides and is maintained on MP252. RAID maintenance is divided into two aspects:  Maintaining the RAID device itself: • In the RAID Device table in the 'Disk Management' screen, click the Edit  icon of the RAID device; the 'RAID Properties' screen appears in which you can: ♦ Enable or disable the RAID device using the 'Enabled' check box. ♦ Change the mount point assigned to the device. ♦ Add or remove the underlying devices (can be done for RAID1 and RAID5 only).  Maintaining the partition: • In the 'RAID Properties' screen, click the device name; the 'Partition Properties' screen appears in which you can check and format the RAID partition. 17.2.3.4 Replacing RAID Underlying Devices Adding or removing a RAID underlying device can only be performed on RAID1 and RAID5 configurations. RAID1 can operate with just one device (although mirroring is unavailable), and RAID5 can operate with one device less than its original amount of devices. The names of the RAID underlying devices appear on the 'RAID Properties' screen. Each device is followed by a status:  Active: The device is controlled by RAID.  Inactive: The device failed to join the RAID array or does not exist.  Faulty: The device joined the RAID array but was marked as faulty due to an error. It is inactive and should be replaced. Replacing a device on RAID1 or RAID5 is done by first removing the faulty device and then adding a new one. The new device's size must be at least the size of the existing one.
MP252 Multimedia Home Gateway  278  Document #: LTRT-23504  User's Manual  ¾ To remove a faulty device from RAID1: 1.  In the 'RAID Properties' screen, click the faulty device's Delete icon. 2.  Click OK. ¾ To add a new device instead of the one removed: 1.  In the RAID Device table in the 'Disk Management' screen, click the Edit  icon of the RAID device; the 'RAID Properties' screen appears with a drop-down list allowing you to choose the new partition to be added. 2.  Choose the partition, and then click OK. After adding a new device, RAID1 starts a recovery process in which the content of the existing partition is mirrored to the new device. If the addition or recovery fails, the device status is set to inactive (this status appears in the 'RAID Properties' screen. In such cases, the device should be removed and another may be added. You can manipulate your disk partitions. However, it is recommended to configure your disks before setting up RAID. Once RAID is configured, you will not be able to delete an underlying partition, or create a new partition on a disk that one of its partitions is underlying RAID, unless you disable or delete the RAID device. Changing a disk's partition table when its partitions are under RAID (even if RAID is disabled) may result in the need to reconstruct the RAID.

MP252 Multimedia Home Gateway  308  Document #: LTRT-23504  User's Manual  18.4 Configuration File The  Configuration File  icon allows you to view, save, and load the MP252 configuration file. Therefore, you can backup and restore your current configuration.  MP252 also supports configuration file encryption, allowing you to load encrypted configuration files (using the file name extensions *.cfx or *.inx). For more information on encrypting a configuration file, see Section 18.4.3 on page 313. MP252 allows you to use un-encrypted passwords in the configuration file (*.cfg or *.ini) that you want to load, and then encrypt the passwords before burning to flash. This is achieved by using the format {“<value>”} in the configuration file for password fields which are normally encrypted. Below are two examples of this feature:  ini file: rg_conf/voip/line/1/auth_password={"foobaa"}  cfg file: (auth_password({"foobaa"})) ¾ To save and restore the configuration file: 1.  In the 'Advanced' screen, click the    icon; the 'Configuration File' screen appears, showing the entire contents of the configuration file. Figure 18-7: Configuration File Screen  2.  You can customize the displayed configuration file, by selecting the following check boxes: • Display modified configuration fields only: Displays only the configuration parameters that have values other than default values.
MP252 Multimedia Home Gateway  18. Maintenance Version 3.4.0  309  June 2011 • Display configuration in flat ini-file format: Displays the configuration file in flat INI-file format. 3.  To back up your current configuration to a file on your PC, click Download Configuration File. The saved configuration file can be used as a backup for the specific MP252's configuration for creating a configuration file for remote configuration update, and for debugging and diagnostics. When creating a configuration backup, disable the two display check boxes (i.e. save a full configuration file in the hierarchic conf format). This file can be loaded back to the same MP252, using the procedure described in Section 18.4.1 on page 310.   Note:  The file is generated according to the selected display option (in Step 2).  4.  To restore your configuration from a file saved on your PC, click Upload Configuration File.   Note:  Do not load this file to a different MP252 as it includes the MAC address, which is unique to MP252 from where it was saved.  When creating a file for remote configuration update, it is recommended to only select the 'Display modified configuration fields only'. This ensures that the file includes only parameters that were modified from their default value. You can choose the conf format or the flat ini-file format. In both cases, it is recommended to review the file and ensure that only the parameters that the user has intended to modify appear. This file can be placed on an FTP or HTTP server for mass configuration update, as described in Remote Configuration Download.   Note:  When rebooting, MP252 restores the settings from its configuration file. However, if reboot attempts fail three times consecutively, MP252 resets the configuration file by restoring factory defaults before attempting to reboot.

Except for the analog or VoIP interfaces, the recovery image supports all interfaces and enables MP252 to reconnect to the Internet and then download the primary software.
MP252 Multimedia Home Gateway  312  Document #: LTRT-23504  User's Manual  18.4.2  Uploading from a Remote Server The procedure below describes how to upload a configuration file to MP252 from a remote server. This allows you to keep your configuration up-to-date, by performing daily checks for a newer configuration file each time MP252 restarts (i.e., automatic update), or manually checking for a newer configuration file. ¾ To upload MP252's configuration file from a remote server: 1.  Click the Upload Configuration File; the screen 'Upload Configuration File' opens. Figure 18-11: Upload Configuration File  2.  Under the 'Load the Configuration File From Remote Server' group, select the checking method and interval: • Automatically check for new configuration file   • Automatic configuration file check disabled 3.  In the 'Remote Configuration File URL' field, enter the URL address of the remote server where the configuration file is located. The URL format is as follows: protocol://server/filename.<conf/ini>, for example: • ftp://10.10.10.10/MP20x_<MAC>.conf • http://20.20.20.20/MP20x_<MAC>.ini Where <MAC> is the MAC address of MP252's WAN. 4.  In the 'Check every' field, enter the interval (in hours) for which MP252 periodically checks for a new configuration file. If set to 0, MP252 checks only once for a new configuration file, and this occurs after it restarts. 5.  From the ‘SSL Mode’ drop-down list, select the type of Secure Socket Layer (SSL) certificate's validation method for accessing the remote server using HTTPS for the following purposes: downloading a new firmware file, downloading a new configuration file, and TR-069. Upon connection, MP252 validates the server's certificate using the selected method: • None: Do not validate the server's certificate (if you do not have a certificate). • Chain: Validate the entire certificate chain (if you have a certificate, but not necessarily signed by a root CA).  • Direct: Ensure that the server's certificate is signed by the root certificate (CA).
MP252 Multimedia Home Gateway  18. Maintenance Version 3.4.0  313  June 2011 6.  Click OK; the download process begins. When downloading completes, a confirmation screen appears, prompting you to confirm loading the new version. 7.  Click  OK to confirm. The upgrade process begins and takes about one minute to complete. At the conclusion of the upgrade process, MP252 automatically reboots and the new software version runs. If a new version is unavailable, click the Check Now button to perform an immediate check (instead of waiting for the next scheduled one). The screen displays a green "Check in progress..." message.  Notes: • For additional security, MP252 can be configured to use HTTPS client-server certification when connecting to a remote server (see Section 13.3 on page 192).• The configuration file can have one of the following two formats: a hierarchical conf file (indicated by file extension *.conf) or a flat ini file (indicated by file extension .ini). • The parameter ‘/rmt_config/version’ defines the version of the configuration file. MP252 uses the new configuration file only if the version that is defined in this fileis later than the current version. By default, the ‘version’ is set to 0. This means that each time Service Providers’ operations personnel require MP252 to download a new configuration file, they need to increment the ‘version’ parameter in the new file (in the .conf file, the ‘version’ parameter is under the section ‘rmt_config’). To simplify the procedure, it is possible to use the current date in YYYYMMDD format as the version field. • The remote configuration file must include only a subset of the complete MP20x.conf file. A recommended procedure is to start with a MP252 restored to its factory settings, modify using the embedded Web server the parameters that should appear in the remote configuration file, and then upload (save) the configuration file. You must save only the modified parameters, as described in 'Remote Administration' on page 253. • The string <MAC> enables the ISP to pre-configure all its deployed MP252s with the same URL and file details (under rmt_config/url) and still have each MP252 download its unique configuration file. Once the URL is configured with the string <MAC>, MP252 that is trying to update its configuration file automatically replaces <MAC> with its own unique MAC address. For example, if there’s a MP252 with a WAN MAC address 00:01:02:03:04:05, the ISP can configure the url to http://myserver.com/my_conf_file_<MAC>.conf - and place a file called ‘my_conf_file_00_01_02_03_04_05.conf’ on the server. • Downloading a configuration file from a remote server can also be performed from the CLI: 1)  Using Telnet, access MP252, and then enter the user name and password.2)  Enter the command rmt_config, for example: rmt_config –u http://myserver.com/my_conf_file.conf 3)  Enter rmt_config without any arguments for more help information.   18.4.3  Encrypting a Configuration File Using CLI Encrypted files include the file name extension *.cfx (instead of *.cfg) or *.inx (instead of *.ini). After MP252 loads the encrypted file from the HTTP server, it automatically identifies the encrypted file by its file name extensions *.cfx or *.inx, and subsequently decrypts the file before saving it to flash memory.  The following procedure describes how to encrypt configuration files. ¾ To encrypt a configuration file:  Run the following CLI shell command (on Linux or Windows PC with OpenSSL installed):
MP252 Multimedia Home Gateway  314  Document #: LTRT-23504  User's Manual  openssl des3 -in <original file> -out <encrypted file> -k <password> -S <salt value> Where, • <original file> is the original clear-text configuration file (*.cfg or *.ini file). • <encrypted file> is the output file (an encrypted *.cfx or *.inx file). • <password> is the password that is used to encrypt the file. • <salt value> is the 8 bytes of a special key value that is combined with the password. The format is 16 hexadecimal digits [0-9,A-F]. An example of this command is shown below: openssl des3 -in c:\temp\try_enc_conf.cfg -out c:\temp\try_enc_conf.cfx -k MyPassword123456 -S 0123456789ABCDEF   Notes:  • You can choose any <salt value> – MP252 does not have to know about it.• A password can be pre-configured in MP252, using the following CLI command: rg_conf_set_obscure /rmt_config/password <password> • You can also define the password in a configuration file that you download from the server. • If you don’t define a password in the configuration file, a default password is used. Different default passwords are defined per customer, according to the config-file url hostname.
MP252 Multimedia Home Gateway  18. Maintenance Version 3.4.0  315  June 2011 18.4.4 Automatic Upload using SIP NOTIFY Message You can enable automatic configuration update for MP252 from a remote server, using the SIP NOTIFY message. The contents of the configuration file can initiate (“push”) the remote server to update MP252 to a desired configuration version. ¾ To “push” a configuration file when a change of parameter is needed: 1.  Create a new configuration file with the required change. 2.  Place the file on the HTTP server. 3.  Send the SIP NOTIFY message to MP252; MP252 integrates the contents of the new file and reboots. ¾ To “push” a configuration file and initiate an upgrade or downgrade: 1.  Create a new configuration file that includes two important entries: a.  In rg_conf/rmt_upd/chech_sync_version, configure the details of the version to which you want MP252 to upgrade or downgrade, for example: (rmt_upd      (check_sync_version(2.6.0_build_1)) ) b.  You may need to update the URL address from where MP252 is downloading the firmware (the path is configured in rmt_upd/url).    Note:  In the case of a downgrade, the service provider MUST provide a configuration file based on a template that matches the version to which the MP252 is downgrading.  2.  Place the file on the HTTP server. 3.  Send the SIP NOTIFY message to MP252; MP252 integrates the contents of the new file and reboots. After rebooting, MP252 compares the currently running version with the version which is configured in rmt_upd/chech_sync_version and then determines whether to connect to the rmt_upd/url for downloading the new *.rmt file. Once the file is downloaded, its headers are parsed, and only if it represents the same version which was configured in the value of rmt_upd/chech_sync_version, does the upgrade/downgrade process begin.  18.5 Firmware Upgrade MP252 provides a built-in mechanism for upgrading its software image. There are two methods for upgrading the software image:  Upgrading from a Computer on the Network: This method uses a software image file that is pre-downloaded on a PC's disk drive or located on an accompanying CD. (See Section 18.5.1 on page 317.)  Upgrading from the Internet: This method also referred to as 'Remote Update', upgrades your firmware by remotely downloading an updated software image file. (See Section 18.5.2 on page 318.) MP252 provides a flash memory of 8 MB, which is capable of storing two firmware images. In addition to the primary firmware, MP252 also stores a recovery firmware, which is used only if the primary image is missing or damaged (e.g. if the user unplugs the power during firmware upgrade). Except for the analog or VoIP interfaces, the recovery image supports all interfaces and enables MP252 to reconnect to the Internet and download the primary firmware.
