When powered-up at the customer site, MP252 first detects the physical WAN type (ADSL or Ethernet) and then attempts the relevant WAN connection methods. The indication for a successful result is connection (i.e., receipt of an IP address) and a ping test. This section describes the recommended process for using the Automatic Dialer. Notes: 7.2.1 • If the Automatic Dialer feature is shipped pre-configured (i.e., enabled), then MP252 automatically detects the Internet dialer type and therefore, configuration of the Internet connection is not necessary. However, it is recommended to manually configure the Internet connection after the Automatic Dialer process has completed (successfully or not). • If you manually configure the Internet connection in the Web interface, the Automatic Dialer feature becomes disabled. Recommended Configuration The recommended factory settings for the Automatic Dialer feature are shown below: (auto_dialer_detect (enabled(1)) (done(0)) (connection_type (0 (type(DHCP)) (enabled(1)) (max_dialer_conn_time(20)) (1 (type(L2TP)) (enabled(1)) (server_ip( )) (username( )) (password( )) (max_dialer_conn_time(120)) (2 (type(PPPOE)) MP252 Multimedia Home Gateway 72 Document #: LTRT-23504 MP252 Multimedia Home Gateway 7.

Version 3.4.0 83 June 2011 User's Manual 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). 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. b. c. 3. Select the ‘Use SIP Proxy’ check box. In the 'Host Name or Address' field, enter the primary proxy's IP address. In the 'Proxy Port' field, enter the primary proxy's port number. Define a redundancy proxy server (under the SIP Proxy and Registrar group): a. a. b. c. Select one of the following check boxes: 'Use SIP Registrar' or 'Use SIP Proxy IP and Port for Registration'. Select the 'Use Redundant Proxy' check box. In the 'Redundant Proxy Address' field, enter the redundant proxy's IP address or DNS name. In the 'Redundant Proxy Port' field, enter the redundant proxy's port number. MP252 Multimedia Home Gateway 84 Document #: LTRT-23504 MP252 Multimedia Home Gateway d. e. 8.

To configure dialing parameters: 1. In the 'Voice Over IP' screen, click the Dialing tab; the following screen appears. Figure 8-3: Dialing Tab Screen 2. Configure the parameters, as required. For a description of the parameters displayed on this screen, see Table 8-2. 3. Click OK to save your settings. MP252 Multimedia Home Gateway 86 Document #: LTRT-23504 MP252 Multimedia Home Gateway 8. Configuring VoIP Parameters 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 is useful 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 the maximum 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 dial plan or digit map. The key is defined in the ‘Complete dialing key’ field, which appears 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 dialed digits even if there is no match in the dial plan or digit map. The default value is the pound (#) key. Note: This parameter is available only if the ‘Enabled dialing complete key’ is selected. Dial Tone Timeout Defines the duration of the dial tone (in seconds). If the limit is exceeded, the dial 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 is exceeded, 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's phone 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-OfBand 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. Version 3.4.0 87 June 2011 User's Manual 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 88. 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 88. 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: 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. 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 and establish a 3-way conference by again pressing Flash after the second call is initiated. During an existing call, if a call comes in (call waiting), pressing Flash puts 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: Flash + 1 holds a call or toggles between two existing calls. Flash + 2 makes a call transfer. 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 modify the 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 modify the 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 85). 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 88 Document #: LTRT-23504 MP252 Multimedia Home Gateway 8. Configuring VoIP Parameters 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 of the 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]x xxx|[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) Version 3.4.0 89 June 2011 User's Manual 8.3 Configuring Media Streaming The procedure below describes how to configure the media streaming parameters.

Contiguous Series of 8 Ports Starting From: DTMF Relay RFC 2833 Defines the RTP payload type used for RFC 2833 DTMF relay packets. The Payload Type 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 is 0-255. The default is 98. MP252 Multimedia Home Gateway 90 Document #: LTRT-23504 MP252 Multimedia Home Gateway 8. Configuring VoIP Parameters 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. Leave this value as 0xb8 (default) if you are unfamiliar with the Differentiated Services IP protocol parameter. Codecs st th 1 - 6 Codec 8.3.1 Defines the voice codec. For more information, see 8.3.1 on page 91. 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. To configure voice and fax parameters: 1. In the 'Voice Over IP' screen, click the Voice and Fax tab; the following screen appears.

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: Transparent = Fax is transferred in-band (like a voice call) - can be used if the codec is G.711 T.38 Relay = Fax is relayed to the remote side according to the T.38 standard Voice Band Data = Switch to G.711 via SIP messaging 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’. Version 3.4.0 93 June 2011 User's Manual 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 received at 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 Modem transport 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.

Configuring VoIP Parameters Parameter CED Transfer Mode Description Enable CNG Detection 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). 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 the CNG signal from the local side, without waiting for the CED signal from the remote side. The default is disabled. Switch To Fax Only By Typically, switching to fax mode is the responsibility of the answering side. 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. To configure supplementary services: 1. In the 'Voice Over IP' screen, click the Services tab; the following screen appears.

Note: This parameter appears only if Call Waiting is enabled. Enable Caller ID Type II Enables caller ID of a waiting call (Called Caller ID type 2). Note: This parameter appears only if Call Waiting is enabled. Call Forward Enabled Enables call forwarding. The Call Forward feature permits a user to redirect incoming calls addressed to another number. The user’s ability to originate calls is unaffected by Call Forward. Note: The Call Forward feature is functional only when MP252 is registered to a proxy. Call Forward Type Defines the type of call forwarding: Unconditional: Incoming calls are forwarded independently of the status of the endpoint. Busy: Incoming calls are forwarded only if the endpoint is busy, i.e., if all lines are active. No Reply: Incoming calls are forwarded only if the endpoint does not answer before a user-defined timeout (see ‘Time for No Reply Forward’ parameter). Note: This parameter appears only if Call Forward is enabled. Time for No Reply Forward Defines the timeout after which the call is forwarded if the endpoint does not answer. If you specify 5 seconds, for example, and 'No Reply' is selected for parameter 'Call Forward Type' (see above), incoming calls are forwarded only after 5 seconds lapse. Note: This parameter is available only when ‘No Reply’ is selected for the parameter 'Call Forward Type'. Key Sequence The default is *72 but users can modify to any sequence of up to 2 digits, i.e., *n or *nm. Do Not Disturb Enabled Enables the Do Not Disturb (DND) feature. This feature allows you to prevent incoming calls from ringing at your phone. When enabled, callers receive a busy signal or an announcement. The DND is activated using the phone keypad. The default is disabled. Key Sequence Defines the key sequence to activate and deactivate the DND feature. 3 Way Conference 3 Way Conference Mode Selects how 3-way conference calls are handled: Local: locally by MP252 Remote: by a remote media server (RFC 4240) Media Server Address The address of the remote media server that handles conference calls.

Configuring VoIP Parameters Configuring Line Settings Before you can make phone calls, you need to configure lines. Lines are SIP logical ID numbers (i.e., telephone numbers), which are registered to the SIP proxy server, and for which you are charged for calls you make on it. MP252 supports two line-configuration modes: One-Line Configuration: In this mode, only one line is configured to represent all the physical telephone extensions on MP252 (i.e., two analog phones and five DECT handsets): • When you receive an incoming call, all the extensions on the line ring, and you can answer from any one of them. When you do answer, the other extensions stop ringing. • If you receive another incoming call when you already have an established call on one extension, all the idle extensions ring, and the busy extension hears a call waiting tone. • You can make outgoing calls from any of the extensions. • You can make multiple concurrent calls (i.e., each extension makes a call to a different destination and at the same time). Three-Lines Configuration: In this mode, three lines can be configured: • Line 1 for the analog telephone connected to the MP252 port labeled Phone 1 • Line 2 for the analog telephone connected to the MP252 port labeled Phone 2 • Line 3 for all the DECT handsets (up to five) To configure lines: 1. In the 'Voice Over IP' screen, click the Line Settings tab; the following screen appears. Figure 8-7: Line Settings Tab Screen 2.

MP252 Multimedia Home Gateway 112 Document #: LTRT-23504 MP252 Multimedia Home Gateway 11 11. Quality of Service 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 128. Version 3.4.0 113 July 2011 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. 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 114 Document #: LTRT-23504 MP252 Multimedia Home Gateway 11. Quality of Service 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. To add a traffic shaping device: 1. Version 3.4.0 From the menu bar, click the QoS menu, and then click the Traffic Shaping tab. 115 June 2011 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 116 Document #: LTRT-23504 MP252 Multimedia Home Gateway 11. Quality of Service 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 115). 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. 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 screen appears. icon; the 'Add Shaping Class' Figure 11-5: Add Shaping Class Screen 4.

Edit the newly added shaping class, by clicking the corresponding Edit Shaping Class' screen appears. icon; the 'Edit 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: 9. • Reserved: reserved (i.e., guaranteed) bandwidth (Committed Information Rate / CIR) in kbps. • Maximum: specify the maximum bandwidth 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 47) 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 118 Document #: LTRT-23504 MP252 Multimedia Home Gateway 11. Quality of Service 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 Version 3.4.0 119 June 2011 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 120. 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 120 Document #: LTRT-23504 MP252 Multimedia Home Gateway 11. Quality of Service 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) 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. Version 3.4.0 After clicking the appropriate New Entry link, the 'Add Traffic Priority Rule' screen appears. 121 June 2011 User's Manual Figure 11-8: Add Traffic Priority Rule Screen 3.

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 47), then these are also displayed as options. To define a new one Scheduler rule, select ‘User Defined’. 7. Click OK to save the settings. 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. Version 3.4.0 123 June 2011 User's Manual To view and set DSCP rules: 1. From the menu bar, click the QoS menu link, and then click the DSCP Settings tab; the following screen appears: Figure 11-9: DSCP Settings Screen MP252 Multimedia Home Gateway 124 Document #: LTRT-23504 MP252 Multimedia Home Gateway 2. 11. Quality of Service To edit an existing entry, click its corresponding Edit icon. To add a new entry, click icon. In both cases, the ’Edit DSCP Settings’ screen appears: the New Figure 11-10: Edit DSCP Settings 3. In the ‘DSCP Value (hex)’ field, enter a hexadecimal number for the DSCP value. 4. 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. Version 3.4.0 125 June 2011 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. 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. The eight 802.1p values are pre-configured with the three priority levels: high, medium and low. You can change these levels for each of the eight values in their respective drop-down list. 3. Click OK to save the settings. MP252 Multimedia Home Gateway 126 Document #: LTRT-23504 MP252 Multimedia Home Gateway 11.6 11. Quality of Service Class Statistics MP252 provides accurate, real-time information on the traffic passing through your defined device classes. For example, the amount of packets sent, dropped, or delayed are just a few of the parameters that you can monitor per each shaping class. Note: Class statistics are available only if you have defined at least one class (otherwise no information is displayed). To view your class statistics: From the menu bar, click the QoS menu link, and then click the Class Statistics tab; the following screen appears: Figure 11-12: Class Statistics Screen Version 3.4.0 127 June 2011 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. 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 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. icon; the screen 'Add Device Traffic Shaping' appears.

Network Connections Network Connections This chapter provides a detailed description on how to configure the following network connections: 12.1 WAN – see Section 12.1 on page 131 LAN – see Section 12.2 on page 151 VLANs – see Section 12.4 on page 181 LAN-WAN Bridging – see Section 12.5 on page 188 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 63. • 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 72. To start the Connection Wizard: 1.

Note: This parameter appears only if On Demand is selected. Time Between Reconnect Attempts Specify the duration between PPP reconnected attempts, as provided by your ISP. PPP Authentication PPP supports four authentication protocols: Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), Microsoft CHAP version 1, and Microsoft CHAP version 2. This section allows you to select the authentication protocols your MP252 may use when negotiating with a PPTP server. Select all the protocols if no information is available about the server's authentication protocols. Note that encryption is performed only if 'Microsoft CHAP', 'Microsoft CHAP version 2', or both are selected. Login User Name: login username according to ISP Login Password: login password according to ISP Support Un-encrypted Password (PAP): PAP is a simple, plaintext authentication scheme. The username and password are requested by your networking peer in plain text. PAP, however, is not a secure authentication protocol. Man-in-the-middle attacks can easily determine the remote access client's password. PAP offers no protection against replay attacks, remote client impersonation, or remote server impersonation. Support Challenge Handshake Authentication (CHAP): CHAP is a challenge-response authentication protocol that uses MD5 to hash the response to a challenge. CHAP protects against replay attacks by using an arbitrary challenge string per authentication attempt. Support Microsoft CHAP: Select this check box if you are communicating with a peer that uses Microsoft CHAP authentication protocol. Support Microsoft CHAP Version 2: Select this check box if you are communicating with a peer that uses Microsoft CHAP Version 2 authentication protocol. PPP Compression The PPP Compression Control Protocol (CCP) is responsible for configuring, enabling, and disabling data compression algorithms on both ends of the point-to-point link. It is also used to signal a failure of the compression/ decompression mechanism in a reliable manner. For each compression algorithm, select one of the following from the drop down menu. Reject: Reject PPP connections with peers that use the compression algorithm. Allow: Allow PPP connections with peers that use the compression algorithm. Require: Ensure a connection with a peer is using the compression algorithm. 12.3.8 PPTP tab The PPTP tab displays the PPTP settings. Note: This tab is applicable only to PPTP connections.

Physical Address The physical address of the network card used for your network. MTU MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission. In the default setting, Automatic, the Telephone Adapter selects the best MTU for your Internet connection. In case you change to manual, you can enter the largest packet size, you should leave this value in the 1200 to 1500 range. Underlying Connection The Ethernet device that the connection is implemented over. Select one of the following Internet Protocol options from the 'Internet Protocol' drop down menu: Version 3.4.0 183 June 2011 User's Manual No IP Address Obtain an IP Address Automatically Use the Following IP Address Note that according to the selection you make in the 'Internet Protocol' drop down menu, the screen refreshes and displays relevant configuration settings. No IP Address: Select 'No IP Address' if you require that your Telephone Adapter has no IP address. This can be useful if you are working in an environment where you are not connected to other networks, such as the Internet. Obtain an IP Address Automatically: Your WAN connection is configured by default to act as a DHCP client. You should keep this configuration in case your service provider supports DHCP, or if you are connecting using a dynamic IP address. The server that assigns the Telephone Adapter with an IP address also assigns a subnet mask. You can override the dynamically assigned subnet mask by selecting the 'Override Subnet Mask' and specifying your own mask instead. You can click the Release button to release the current leased IP address. Once the address has been released, the button text changes to 'Renew'. Use the Renew button to renew the leased IP address. Use the Following IP Address: Your WAN connection can be configured using a permanent (static) IP address. Your service provider should provide you with this IP address, subnet mask and the default Telephone Adapter IP address. 12.4.1.1 IP Address Distribution The 'IP Address Distribution' section allows you to configure the device's Dynamic Host Configuration Protocol (DHCP) server parameters. The DHCP automatically assigns IP addresses to network PCs. If you enable this feature, make sure that you also configure your network PCs as DHCP clients. For a comprehensive description of this feature, see Section 10.28. Select one of the following options from the 'IP Address Distribution' drop-down list: Table 12-7: IP Address Distribution Parameters Parameter Description DHCP Server Start IP Address The first IP address that may be assigned to a LAN host. Since the device's default IP address is 192.168.2.1, this address must be 192.168.2.2 or greater. End IP Address The last IP address in the range that can be used to automatically assign IP addresses to LAN hosts. Subnet Mask A mask used to determine to what subnet an IP address belongs. An example of a subnet mask value is 255.255.0.0. Lease Time In Minutes Each device is assigned an IP address by the DHCP server for a this amount of time, when it connects to the network. When the lease expires the server determines if the computer has disconnected from the network. If it has, 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. Provide Host Name If If the DHCP client does not have a host name, the device automatically assigns Not Specified by one for him.

Network Connections Table 12-10: Routing Parameters Parameter Description Routing Select 'Advanced' or 'Basic' routing. Routing Mode Select one of the following Routing modes: Route: Use route mode if you want your device to function as a router between two networks. NAT: Network Address Translation (NAT) translates IP addresses to a valid, public address on the Internet. This adds security since internal LAN addresses are not transmitted over the Internet. In addition, NAT allows many addresses to exist behind a single valid address. Use the NAT routing mode if your LAN consists of a single device, otherwise collisions may occur if more than one device attempts to communicate using the same port. NAPT: Network Address and Port Translation (NAPT) refers to network address translation involving the mapping of port numbers, allowing multiple machines to share a single IP address. Use NAPT if your LAN encompasses multiple devices, a topology that necessitates port translation in addition to address translation. Device Metric The device metric is a value used by the device to determine whether one route is superior to another, considering parameters such as bandwidth, delay, and more. Default Route Select this check box to define this device as a the default route. Multicast IGMP Proxy Internal IGMP proxy enables the system to issue IGMP host messages on behalf of hosts that the system discovered through standard IGMP interfaces.

Remote MP252 Management 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 Version 3.4.0 193 July 2011 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 194 Document #: LTRT-23504 MP252 Multimedia Home Gateway 13. Remote MP252 Management 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 Version 3.4.0 195 June 2011 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 Network Connections System Current status information per line: Phone state Registration status Source, codec and type of current call Packet loss, jitter and delay of current call Current status information per interface: Connection status Allocated IP address Received and transmitted packets Software version information Hardware version information System Up time MP252 Multimedia Home Gateway 196 Document #: LTRT-23504 MP252 Multimedia Home Gateway 13. Remote MP252 Management 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 Network Connections Notifications: Registration error or timeout Logged Events: End of call (Call Detail Record logging) SIP messages logging (optional - for debugging) Notifications: Connection up / down Security Logged Events: Security log (configurable) System Notifications: System restart 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 of operation, 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. Version 3.4.0 197 June 2011 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. To enable remote access to MP252 services: 1. In the 'Advanced' screen, click the Remote Administration Administration' screen appears.

When a service provider implements remote provisioning in which a unique configuration file (per MP252) is placed on a server located on the WAN, the service provider can ensure that only its deployed MP252 units are able to connect to the HTTP server via HTTPS. This is performed by using a certification validation process (client-server). There are two types of certificates: Self-signed certificates Certificate Authority (CA) signed certificates The procedure below describes how to operate with self-signed certificates. To operate with self-signed certificates: 1. In the 'Advanced' screen, click the icon; the 'Certificates' screen appears. Figure 13-4: New Certificates Screen 2. Create a self-signed certificate: Note: You can also create a self-signed certificate using the OpenSSL utility, downloaded from http://sial.org/howto/openssl/self-signed. a. b. Select the MP252’s Local tab. Click the Create Self Signed Certificate button; the 'Create Self Signed X509 Certificate' screen appears. MP252 Multimedia Home Gateway 200 Document #: LTRT-23504
