User s Guide 31CHAPTER  1 Getting Started1.1  About Your WiMAX Modem The WiMAX Modem has a built-in switch and one phone port. It allows you to access the Internet by connecting to a WiMAX wireless network. You can use a traditional analog telephone to make Internet calls using the WiMAX Modem’s Voice over IP (VoIP) communication capabilities. You can configure firewall and content filtering as well as a host of other features. The web browser-based Graphical User Interface (GUI), also known as the web configurator, provides easy management.See Chapter 21 on page 223 for a complete list of features for your model.1.1.1  WiMAX Internet AccessConnect your computer or network to the WiMAX Modem for WiMAX Internet access. See the Quick Start Guide for instructions on hardware connection.In a wireless metropolitan area network (MAN), the WiMAX Modem connects to a WiMAX base station (BS) for Internet access. The following diagram shows a notebook computer equipped with the WiMAX Modem connecting to the Internet through a WiMAX base station (marked BS).Figure 1   Mobile Station and Base StationWhen the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network.
Chapter 1Getting StartedUser s Guide32Use content filtering to block access to web sites with URLs containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude particular computers on your network from content filtering. For example, you could block access to certain web sites for the kids.1.1.2  Make Calls via Internet Telephony Service ProviderIn a home or small office environment, you can use the WiMAX Modem to make and receive the following types of VoIP telephone calls:•Peer-to-Peer calls - Use the WiMAX Modem to make a call directly to the recipient’s IP address without using a SIP proxy server.Figure 2   WiMAX Modem s VoIP Features - Peer-to-Peer Calls•Calls via a VoIP service provider - The WiMAX Modem sends your call to a VoIP service provider’s SIP server which forwards your calls to either VoIP or PSTN phones.Figure 3   WiMAX Modem s VoIP Features - Calls via VoIP Service Provider

A LAN, as its name implies, is limited to a local area such as a home or office environment. LANs have different topologies, the most common being the linear bus and the star configuration.IP AddressIP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts.Subnet MaskThe subnet mask specifies the network number portion of an IP address. Your device will compute the subnet mask automatically based on the IP Address that
Chapter 5The Setup ScreensUser s Guide54you entered. You do not need to change the computer subnet mask unless you are instructed to do so.DaytimeA network protocol used by devices for debugging and time measurement. A computer can use this protocol to set its internal clock but only if it knows in which order the year, month, and day are returned by the server. Not all servers use the same format.TimeA network protocol for retrieving the current time from a server. The computer issuing the command compares the time on its clock to the information returned by the server, adjusts itself automatically for time zone differences, then calculates the difference and corrects itself if there has been any temporal drift.NTPNTP stands for Network Time Protocol. It is employed by devices connected to the Internet in order to obtain a precise time setting from an official time server. These time servers are accurate to within 200 microseconds.5.1.3  Before You Begin•Make sure that you have made all the appropriate hardware connections to the WiMAX Modem, as described in the Quick Start Guide.•Make sure that you have logged in to the web configurator at least one time and changed your password from the default, as described in the Quick Start Guide.5.2  Set IP AddressClick the SETUP icon in the navigation bar to set up the WiMAX Modem’s IP address and subnet mask.

 Chapter 6The LAN Configuration ScreensUser s Guide 676.6.1  IP Address and Subnet MaskSimilar to the way houses on a street share a common street name, computers on a LAN share one common network number.Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the Network Address Translation (NAT) feature of the WiMAX Modem. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network.Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your WiMAX Modem, but make sure that no other device on your network is using that IP address.The subnet mask specifies the network number portion of an IP address. Your WiMAX Modem will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the WiMAX Modem unless you are instructed to do otherwise.6.6.2  DHCP SetupDHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the WiMAX Modem as a DHCP server or disable it. When configured as a server, the WiMAX Modem provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on your LAN, or else each computer must be manually configured.The WiMAX Modem is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool). See the product specifications in the appendices. Do not assign static IP addresses from the DHCP pool to your LAN computers.These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), see Section 6.3 on page 62.
Chapter 6The LAN Configuration ScreensUser s Guide686.6.3  LAN TCP/IPThe WiMAX Modem has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability.These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), see Section 6.2 on page 60.6.6.4  DNS Server AddressDNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a machine before you can access it. The DNS server addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP address and subnet mask.There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up. If your ISP gives you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup, otherwise, leave them blank.Some ISPs choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation. The WiMAX Modem supports the IPCP DNS server extensions through the DNS proxy feature.If the Primary and Secondary DNS Server fields in the LAN Setup screen are notspecified, for instance, left as 0.0.0.0, the WiMAX Modem tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the WiMAX Modem, the WiMAX Modem forwards the query to the real DNS server learned through IPCP and relays the response back to the computer.Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the LAN Setup screen. This way, the WiMAX Modem can pass the DNS servers to the computers and the computers can query the DNS server directly without the WiMAX Modem’s intervention.
 Chapter 6The LAN Configuration ScreensUser s Guide 696.6.5  RIP SetupRIP (Routing Information Protocol) allows a router to exchange routing information with other routers. The RIP Direction field controls the sending and receiving of RIP packets.  When set to:•Both - the WiMAX Modem will broadcast its routing table periodically and incorporate the RIP information that it receives.•In Only - the WiMAX Modem will not send any RIP packets but will accept all RIP packets received.•Out Only - the WiMAX Modem will send out RIP packets but will not accept any RIP packets received.•None - the WiMAX Modem will not send any RIP packets and will ignore any RIP packets received.The Version field controls the format and the broadcasting method of the RIP packets that the WiMAX Modem sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology.Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.6.6.6  MulticastTraditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1.IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address 224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers group.The WiMAX Modem supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the WiMAX Modem queries all directly connected
Chapter 6The LAN Configuration ScreensUser s Guide70networks to gather group membership. After that, the WiMAX Modem periodically updates this information. IP multicasting can be enabled/disabled on the WiMAX Modem LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces.

Mobile stations use the IEEE 802.16e standard and are able to maintain connectivity while switching their connection from one base station to another base station (handover) while subscriber stations use other standards that do not have this capability (IEEE 802.16-2004, for
Chapter 7The WAN Configuration ScreensUser s Guide72example). The following figure shows an MS-equipped notebook computer MS1moving from base station BS1’s coverage area and connecting to BS2.Figure 24   WiMax: Mobile StationWiMAX technology uses radio signals (around 2 to 10 GHz) to connect subscriber stations and mobile stations to local base stations. Numerous subscriber stations and mobile stations connect to the network through a single base station (BS), as in the following figure. Figure 25   WiMAX: Multiple Mobile StationsA base station's coverage area can extend over many hundreds of meters, even under poor conditions. A base station provides network access to subscriber stations and mobile stations, and communicates with other base stations.The radio frequency and bandwidth of the link between the WiMAX Modem and the base station are controlled by the base station. The WiMAX Modem follows the base station’s configuration.

User s Guide 83CHAPTER  8 The NAT Configuration Screens8.1  OverviewUse these screens to configure port forwarding and trigger ports for the WiMAX Modem. You can also enable and disable SIP, FTP, and H.323 ALG.Network Address Translation (NAT) maps a host’s IP address within one network to a different IP address in another network. For example, you can use a NAT router to map one IP address from your ISP to multiple private IP addresses for the devices in your home network.8.1.1  What You Can Do in This Chapter•The General screen (Section 8.2 on page 83) lets you enable or disable NAT and to allocate memory for NAT and firewall rules.•The Port Forwarding screen (Section 8.3 on page 84) lets you look at the current port-forwarding rules in the WiMAX Modem, and to enable, disable, activate, and deactivate each one.•The Trigger Port screen (Section 8.4 on page 88) lets you maintain trigger port forwarding rules for the WiMAX Modem.•The ALG screen (Section 8.5 on page 91) lets you enable and disable SIP (VoIP), FTP (file transfer), and H.323 (audio-visual) ALG in the WiMAX Modem.8.2  GeneralClick ADVANCED > NAT Configuration > General to enable or disable NAT and to allocate memory for NAT and firewall rules.Figure 32   ADVANCED > NAT Configuration > General
Chapter 8The NAT Configuration ScreensUser s Guide84The following table describes the labels in this screen.8.3  Port Forwarding A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world.Use the ADVANCED > NAT Configuration > Port Forwarding screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.Table 24   ADVANCED > NAT Configuration > GeneralLABEL DESCRIPTIONEnable Network Address Translation Select this if you want to use port forwarding, trigger ports, or any of the ALG.Max NAT/Firewall Session Per User When computers use peer to peer applications, such as file sharing applications, they may use a large number of NAT sessions. If you do not limit the number of NAT sessions a single client can establish, this can result in all of the available NAT sessions being used. In this case, no additional NAT sessions can be established, and users may not be able to access the Internet. Each NAT session establishes a corresponding firewall session. Use this field to limit the number of NAT/firewall sessions each client computer can establish through the WiMAX Modem. If your network has a small number of clients using peer to peer applications, you can raise this number to ensure that their performance is not degraded by the number of NAT sessions they can establish. If your network has a large number of users using peer to peer applications, you can lower this number to ensure no single client is using all of the available NAT sessions.

Chapter 8The NAT Configuration ScreensUser s Guide888.4  Trigger PortSome services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address, Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The WiMAX Modem records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the WiMAX Modem's WAN port receives a response with a specific port number and protocol ("incoming" port), the WiMAX Modem forwards the traffic to the LAN IP address of the computer that sent the request. After that computer’s connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application.Click ADVANCED > NAT Configuration > Trigger Port to maintain trigger port forwarding rules for the WiMAX Modem.Figure 36   ADVANCED > NAT Configuration > Trigger Port

Chapter 8The NAT Configuration ScreensUser s Guide908.4.1  Trigger Port Forwarding ExampleThe following is an example of trigger port forwarding. In this example, J is Jane’s computer and S is the Real Audio server.Figure 37   Trigger Port Forwarding Example1Jane requests a file from the Real Audio server (port 7070).2Port 7070 is a “trigger” port and causes the WiMAX Modem to record Jane’s computer IP address. The WiMAX Modem associates Jane's computer IP address with the "incoming" port range of 6970-7170.3The Real Audio server responds using a port number ranging between 6970-7170.4The WiMAX Modem forwards the traffic to Jane’s computer IP address. 5Only Jane can connect to the Real Audio server until the connection is closed or times out. The WiMAX Modem times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). Two points to remember about trigger ports:1Trigger events only happen on data that is coming from inside the WiMAX Modem and going to the outside.2If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN can’t trigger it.
 Chapter 8The NAT Configuration ScreensUser s Guide 918.5  ALGSome applications, such as SIP, cannot operate through NAT (are NAT un-friendly) because they embed IP addresses and port numbers in their packets’ data payload. Some NAT routers may include a SIP Application Layer Gateway (ALG). An Application Layer Gateway (ALG) manages a specific protocol (such as SIP, H.323 or FTP) at the application layer. A SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses embedded in the data stream.Click ADVANCED > NAT Configuration > ALG to enable and disable SIP (VoIP), FTP (file transfer), and H.323 (audio-visual) ALG in the WiMAX Modem.Figure 38   ADVANCED > NAT Configuration > ALGThe following table describes the labels in this screen.Table 29   ADVANCED > NAT Configuration > ALGLABEL DESCRIPTIONEnable SIP ALG Select this to make sure SIP (VoIP) works correctly with port-forwarding and port-triggering rules.Enable FTP ALG Select this to make sure FTP (file transfer) works correctly with port-forwarding and port-triggering rules.Enable H.323 ALG Select this to make sure H.323 (audio-visual programs, such as NetMeeting) works correctly with port-forwarding and port-triggering rules.Apply Click to save your changes.CancelClick to return to the previous screen without saving your changes.

If you leave this blank, the domain name obtained by DHCP from the ISP is used. While you must enter the host name (System Name) on each individual computer, the domain name can be assigned from the WiMAX Modem via DHCP.DNS Server Address AssignmentUse DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The WiMAX Modem can get the DNS server addresses in the following ways:1The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in the SYSTEM General screen.2If the ISP did not give you DNS server information, leave the DNS Server fields in the SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the DNS server IP addresses.

Chapter 9The System Configuration ScreensUser s Guide969.3  Dynamic DNSDynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access your FTP server or Web site on your own computer using a domain name (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address.First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name. The Dynamic DNS service provider will give you a password or key.Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname.Note: If you have a private WAN IP address, then you cannot use Dynamic DNS.Retype to Confirm Enter the new password again.ApplyClick to save your changes.ResetClick to restore your previously saved settings.Table 30   ADVANCED > System Configuration > General (continued)LABEL DESCRIPTION

User s Guide 103CHAPTER 10The Service ConfigurationScreens10.1  OverviewThe VOICE > Service Configuration screens allow you to set up your voice accounts and configure your QoS settings.VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows you to make phone calls and send faxes over the Internet at a fraction of the cost of using the traditional circuit-switched telephone network. You can also use servers to run telephone service applications like PBX services and voice mail. Internet Telephony Service Provider (ITSP) companies provide VoIP service. A company could alternatively set up an IP-PBX and provide it’s own VoIP service.Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to handle a telephone call. VoIP can use advanced voice coding techniques with compression to reduce the required bandwidth.10.1.1  What You Can Do in This Chapter•The SIP Settings screen (Section 10.2 on page 105) lets you setup and maintain your SIP account(s) in the WiMAX Modem.•The Advanced SIP Settings screen (Section 10.2.1 on page 107) lets you set up and maintain advanced settings for each SIP account•The QoS screen (Section 10.3 on page 113) lets you set up and maintain ToS and VLAN settings for the WiMAX Modem.10.1.2  What You Need to KnowThe following terms and concepts may help as you read through this chapter.SIPThe Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and
Chapter 10The Service Configuration ScreensUser s Guide104multimedia sessions over the Internet. SIP signaling is separate from the media for which it handles sessions. The media that is exchanged during the session can use a different path from that of the signaling. SIP handles telephone calls and can interface with traditional circuit-switched telephone networks.SIP IdentitiesA SIP account uses an identity (sometimes referred to as a SIP address). A complete SIP identity is called a SIP URI (Uniform Resource Identifier). A SIP account's URI identifies the SIP account in a way similar to the way an e-mail address identifies an e-mail account. The format of a SIP identity is SIP-Number@SIP-Service-Domain.SIP NumberThe SIP number is the part of the SIP URI that comes before the “@” symbol. A SIP number can use letters like in an e-mail address (johndoe@your-ITSP.com for example) or numbers like a telephone number (1122334455@VoIP-provider.com for example).SIP Service DomainThe SIP service domain of the VoIP service provider (the company that lets you make phone calls over the Internet) is the domain name in a SIP URI. For example, if the SIP address is 1122334455@VoIP-provider.com, then “VoIP-provider.com” is the SIP service domain.SIP Register ServerA SIP register server maintains a database of SIP identity-to-IP address (or domain name) mapping. The register server checks your user name and password when you register. RTPWhen you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to handle voice data transfer. See RFC 1889 for details on RTP.Use NATIf you know the NAT router’s public IP address and SIP port number, you can use the Use NAT feature to manually configure the WiMAX Modem to use a them in the SIP messages. This eliminates the need for STUN or a SIP ALG. You must also configure the NAT router to forward traffic with this port number to the WiMAX Modem.
 Chapter 10The Service Configuration ScreensUser s Guide 10510.1.3  Before you Begin•Ensure that you have all of your voice account information on hand. If not, contact your voice account service provider to find out which settings in this chapter you should configure in order to use your telephone with the WiMAX Modem.•Connect your WiMAX Modem to the Internet, as described in the Quick Start Guide. If you have not already done so, then you will not be able to test your VoIP settings.10.2  SIP SettingsClick VOICE > Service Configuration > SIP Setting to setup and maintain your SIP account(s) in the WiMAX Modem.

 Chapter 10The Service Configuration ScreensUser s Guide 10710.2.1  Advanced SIP SettingsThis section describes the features of the Advanced SIP settings screen.10.2.1.1  STUNSTUN (Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators) allows the WiMAX Modem to find the presence and types of NAT routers and/or firewalls between it and the public Internet. STUN also allows the WiMAX Modem to find the public IP address that NAT assigned, so the WiMAX Modem can embed it in the SIP data stream. STUN does not work with symmetric NAT routers or firewalls. See RFC 3489 for details on STUN.The following figure shows how STUN works. 1The WiMAX Modem (A) sends SIP packets to the STUN server (B).2The STUN server (B) finds the public IP address and port number that the NAT router used on the WiMAX Modem’s SIP packets and sends them to the WiMAX Modem.3The WiMAX Modem uses the public IP address and port number in the SIP packets that it sends to the SIP server (C).Figure 46   STUN Example10.2.1.2  Outbound ProxyYour VoIP service provider may host a SIP outbound proxy server to handle all of the WiMAX Modem’s VoIP traffic. This allows the WiMAX Modem to work with any type of NAT router and eliminates the need for STUN or a SIP ALG. Turn off a SIP ALG on a NAT router in front of the WiMAX Modem to keep it from re-translating the IP address (since this is already handled by the outbound proxy server).10.2.1.3  Voice CodingA codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital signals back into voice signals. The WiMAX Modem supports the following codecs.ABCNAT1
Chapter 10The Service Configuration ScreensUser s Guide108•G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures analog signal amplitudes at regular time intervals (sampling) and converts them into digital bits (quantization). Quantization “reads” the analog signal and then “writes” it to the nearest digital value. For this reason, a digital sample is usually slightly different from its analog original (this difference is known as “quantization noise”). G.711 provides excellent sound quality but requires 64kbps of bandwidth.•G.723 is an Adaptive Differential Pulse Code Modulation (ADPCM) waveform codec. Differential (or Delta) PCM is similar to PCM, but encodes the audio signal based on the difference between one sample and a prediction based on previous samples, rather than encoding the sample’s actual quantized value. Many thousands of samples are taken each second, and the differences between consecutive samples are usually quite small, so this saves space and reduces the bandwidth necessary. However, DPCM produces a high quality signal (high signal-to-noise ratio or SNR) for high difference signals (where the actual signal is very different from what was predicted) but a poor quality signal (low SNR) for low difference signals (where the actual signal is very similar to what was predicted). This is because the level of quantization noise is the same at all signal levels. Adaptive DPCM solves this problem by adapting the difference signal’s level of quantization according to the audio signal’s strength. A low difference signal is given a higher quantization level, increasing its signal-to-noise ratio. This provides a similar sound quality at all signal levels. G.723 provides high quality sound and requires 20 or 40 kbps.•G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec. It uses a filter based on information about how the human vocal tract produces sounds. The codec analyzes the incoming voice signal and attempts to synthesize it using its list of voice elements. It tests the synthesized signal against the original and, if it is acceptable, transmits details of the voice elements it used to make the synthesis. Because the codec at the receiving end has the same list, it can exactly recreate the synthesized audio signal.G.729 provides good sound quality and reduces the required bandwidth to 8kbps.10.2.1.4  MWI (Message Waiting Indication)Enable Message Waiting Indication (MWI) enables your phone to give you a message–waiting (beeping) dial tone when you have one or more voice messages. Your VoIP service provider must have a messaging system that sends message-waiting-status SIP packets as defined in RFC 3842.

G.711 provides high voice quality but requires more bandwidth (64 kbps).•G.711A is typically used in Europe.•G.711u is typically used in North America and Japan.•G.723 provides good voice quality, and requires 20 or 40 kbps.•G.729 requires only 8 kbps.The WiMAX Modem must use the same codec as the peer. When two SIP devices start a SIP session, they must agree on a codec.For more on voice compression, see Voice Coding on page107DTMF Mode Control how the WiMAX Modem handles the tones that your telephone makes when you push its buttons. You should use the same mode your VoIP service provider uses.•RFC 2833 - send the DTMF tones in RTP packets•PCM - send the DTMF tones in the voice data stream. This method works best when you are using a codec that does not use compression (like G.711). Codecs that use compression (like G.729) can distort the tones.•SIP INFO - send the DTMF tones in SIP messagesSTUNActiveSelect this if all of the following conditions are satisfied.•There is a NAT router between the WiMAX Modem and the SIP server.•The NAT router is not a SIP ALG.•Your VoIP service provider gave you an IP address or domain name for a STUN server.•Otherwise, clear this field.Table 37   VOICE > Service Configuration > SIP Settings > Advanced (continued)LABEL DESCRIPTION

Only stations within the same group can communicate with each other. Your WiMAX Modem can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to the network. This allows the WiMAX Modem to communicate with a SIP
Chapter 10The Service Configuration ScreensUser s Guide114server that is a member of the same VLAN group. Some ISPs use the VLAN tag to identify voice traffic and give it priority over other traffic.Click VOICE > Service Configuration > QoS to set up and maintain ToS and VLAN settings for the WiMAX Modem.

A calls B. 1A sends a SIP INVITE request to B. This message is an invitation for B to participate in a SIP telephone call. 2B sends a response indicating that the telephone is ringing.3B sends an OK response after the call is answered. 4A then sends an ACK message to acknowledge that B has answered the call. 5Now A and B exchange voice media (talk). 6After talking, A hangs up and sends a BYE request. 7B replies with an OK response confirming receipt of the BYE request and the call is terminated.Table 40   SIP Call ProgressionA B1. INVITE2. Ringing3. OK4. ACK 5.Dialogue (voice traffic)6. BYE7. OK
Chapter 10The Service Configuration ScreensUser s Guide11610.4.2  SIP Client ServerSIP is a client-server protocol. A SIP client is an application program or device that sends SIP requests. A SIP server responds to the SIP requests. When you use SIP to make a VoIP call, it originates at a client and terminates at a server. A SIP client could be a computer or a SIP phone. One device can act as both a SIP client and a SIP server. 10.4.3  SIP User Agent A SIP user agent can make and receive VoIP telephone calls. This means that SIP can be used for peer-to-peer communications even though it is a client-server protocol. In the following figure, either A or B can act as a SIP user agent client to initiate a call. A and B can also both act as a SIP user agent to receive the call.Figure 49   SIP User Agent10.4.4  SIP Proxy ServerA SIP proxy server receives requests from clients and forwards them to another server.In the following example, you want to use client device A to call someone who is using client device C. 1The client device (A in the figure) sends a call invitation to the SIP proxy server (B).AB
 Chapter 10The Service Configuration ScreensUser s Guide 1172The SIP proxy server forwards the call invitation to C.Figure 50   SIP Proxy Server10.4.5  SIP Redirect ServerA SIP redirect server accepts SIP requests, translates the destination address to an IP address and sends the translated IP address back to the device that sent the request. Then the client device that originally sent the request can send requests to the IP address that it received back from the redirect server. Redirect servers do not initiate SIP requests. In the following example, you want to use client device A to call someone who is using client device C. 1Client device A sends a call invitation for C to the SIP redirect server (B).2The SIP redirect server sends the invitation back to A with C’s IP address (or domain name).ACB12
Chapter 10The Service Configuration ScreensUser s Guide1183Client device A then sends the call invitation to client device C.Figure 51   SIP Redirect Server10.4.6  NAT and SIPThe WiMAX Modem must register its public IP address with a SIP register server. If there is a NAT router between the WiMAX Modem and the SIP register server, the WiMAX Modem probably has a private IP address. The WiMAX Modem lists its IP address in the SIP message that it sends to the SIP register server. NAT does not translate this IP address in the SIP message. The SIP register server gets the WiMAX Modem’s IP address from inside the SIP message and maps it to your SIP identity. If the WiMAX Modem has a private IP address listed in the SIP message, the SIP server cannot map it to your SIP identity. See Chapter8 The NAT Configuration Screens for more information.Use a SIP ALG (Application Layer Gateway), Use NAT, STUN, or outbound proxy to allow the WiMAX Modem to list its public IP address in the SIP messages.10.4.7  DiffServDiffServ is a class of service (CoS) model that marks packets so that they receive specific per-hop treatment at DiffServ-compliant network devices along the route based on the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the level of service desired. This allows the intermediary DiffServ-compliant network devices to handle the packets differently depending on the code points without the need to negotiate paths or remember state information for every flow. In addition, applications do not have to request a particular service or give advanced notice of where the traffic is going.ACB132
 Chapter 10The Service Configuration ScreensUser s Guide 11910.4.8  DSCP and Per-Hop Behavior DiffServ defines a new DS (Differentiated Services) field to replace the Type of Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define up to 64 service levels. The following figure illustrates the DS field. Figure 52   DiffServ: Differentiated Service FieldDSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping. The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different priorities of forwarding. Resources can then be allocated according to the DSCP values and the configured policies.DSCP(6-bit)Unused(2-bit)

This lets the WiMAX Modem reduce the bandwidth that a call uses by not transmitting “silent packets” when you are not speaking.When using VAD, the WiMAX Modem generates comfort noise when the other party is not speaking. The comfort noise lets you know that the line is still connected as total silence could easily be mistaken for a lost connection.Echo Cancellation G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk.

On newer telephones, there should be a "flash" key (button) that generates the signal electronically. If the flash key is not available, you can tap (press and immediately release) the hook by hand to achieve the same effect. However, using the flash key is preferred since the timing is much more precise. The WiMAX Modem may interpret manual tapping as hanging up if the duration is too longYou can invoke all the supplementary services by using the flash key. 11.5.2  Europe Type Supplementary Phone ServicesThis section describes how to use supplementary phone services with the Europe TypeCall Service Mode.

User s Guide 137CHAPTER 13The Certificates Screens13.1  OverviewUse the TOOLS > Certificates screens to manage public key certificates on the WiMAX Modem.The WiMAX Modem can use public key certificates (also sometimes called “digital IDs”) to authenticate users. Certificates are based on public-private key pairs. A certificate contains the certificate owner’s identity and public key. Certificates provide a way to exchange public keys for use in authentication.Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a certificate authority such as VeriSign, Comodo, or Network Solutions (to name a few) receives a certificate request from a website operator, they confirm that the web domain and contact information in the request match those on public record with a domain name registrar. If they match, then the certificate is issued to the website operator, who then places it on his site to be issued to all visiting web browsers to let them know that the site is legitimate.13.1.1  What You Can Do in This Chapter•The My Certificates screen (Section 13.2 on page 138) lets you generate and export self-signed certificates or certification requests and import the WiMAX Modem’s CA-signed certificates.•The Trusted CAs screen (Section 13.3 on page 147) lets you display a summary list of certificates of the certification authorities that you have set the WiMAX Modem to accept as trusted.13.1.2  What You Need to KnowThe following terms and concepts may help as you read through this chapter.Certificate AuthoritiesA Certification Authority (CA) issues certificates and guarantees the identity of each certificate owner. There are commercial certification authorities like CyberTrust or VeriSign and government certification authorities. You can use the

 Chapter 13The Certificates ScreensUser s Guide 15313.4.1  Certificate AuthoritiesWhen using public-key cryptology for authentication, each host has two keys. One key is public and can be made openly available. The other key is private and must be kept secure. These keys work like a handwritten signature (in fact, certificates are often referred to as “digital signatures”). Only you can write your signature exactly as it ought to look. When people know what your signature ought to look like, they can verify whether something was signed by you, or by someone else. In the same way, your private key “writes” your digital signature and your public key allows people to verify whether data was signed by you, or by someone else. This process works as follows.1Tim wants to send a message to Jenny. He needs her to be sure that it comes from him, and that the message content has not been altered by anyone else along the way. Tim generates a public key pair (one public key and one private key). 2Tim keeps the private key and makes the public key openly available. This means that anyone who receives a message seeming to come from Tim can read it and verify whether it is really from him or not. 3Tim uses his private key to sign the message and sends it to Jenny.4Jenny receives the message and uses Tim’s public key to verify it. Jenny knows that the message is from Tim, and she knows that although other people may have been able to read the message, no-one can have altered it (because they cannot re-sign the message with Tim’s private key).5Additionally, Jenny uses her own private key to sign a message and Tim uses Jenny’s public key to verify the message.The WiMAX Modem uses certificates based on public-key cryptology to authenticate users attempting to establish a connection, not to encrypt the data that you send after establishing a connection. The method used to secure the data that you send through an established connection depends on the type of connection. For example, a VPN tunnel might use the triple DES encryption algorithm.The certification authority uses its private key to sign certificates. Anyone can then use the certification authority’s public key to verify the certificates.A certification path is the hierarchy of certification authority certificates that validate a certificate. The WiMAX Modem does not trust a certificate if any certificate on its path has expired or been revoked.
Chapter 13The Certificates ScreensUser s Guide154Certification authorities maintain directory servers with databases of valid and revoked certificates. A directory of certificates that have been revoked before the scheduled expiration is called a CRL (Certificate Revocation List). The WiMAX Modem can check a peer’s certificate against a directory server’s list of revoked certificates. The framework of servers, software, procedures and policies that handles keys is called PKI (public-key infrastructure).13.4.1.1  Advantages of CertificatesCertificates offer the following benefits.•The WiMAX Modem only has to store the certificates of the certification authorities that you decide to trust, no matter how many devices you need to authenticate. •Key distribution is simple and very secure since you can freely distribute public keys and you never need to transmit private keys.13.4.1.2  Self-signed CertificatesYou can have the WiMAX Modem act as a certification authority and sign its own certificates.13.4.1.3  Factory Default CertificateThe WiMAX Modem generates its own unique self-signed certificate when you first turn it on. This certificate is referred to in the GUI as the factory default certificate. 13.4.1.4  Certificate File FormatsAny certificate that you want to import has to be in one of these file formats:•Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.•PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters, uppercase letters and numerals to convert a binary X.509 certificate into a printable form.•Binary PKCS#7: This is a standard that defines the general syntax for data (including digital signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The private key is not included. The WiMAX Modem currently allows the importation of a PKS#7 file that contains a single certificate. •PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable form.Note: Be careful to not convert a binary file to text during the transfer process. It is easy for this to occur since many programs use text files by default.
 Chapter 13The Certificates ScreensUser s Guide 15513.4.2  Verifying a CertificateBefore you import a certificate into the WiMAX Modem, you should verify that you have the correct certificate. This is especially true of trusted certificates since the WiMAX Modem also trusts any valid certificate signed by any of the imported trusted certificates.13.4.2.1  Checking the Fingerprint of a Certificate on Your ComputerA certificate’s fingerprints are message digests calculated using the MD5 or SHA1 algorithms. The following procedure describes how to check a certificate’s fingerprint to verify that you have the actual certificate. 1Browse to where you have the certificate saved on your computer. 2Make sure that the certificate has a “.cer” or “.crt” file name extension. (On some Linux distributions, the file extension may be “.der”.)Figure 66   Remote Host Certificates

User s Guide 157CHAPTER 14The Firewall Screens14.1  OverviewUse the TOOLS > Firewall screens to manage WiMAX Modem’s firewall security measures.Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term "firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from an untrusted network. Of course, firewalls cannot solve every security problem.A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-security policy. In addition, specific policies must be implemented within the firewall itself.14.1.1  What You Can Do in This Chapter•The General screen (Section 14.2 on page 158) lets you configure the basic settings for your firewall.•The Services screen (Section 14.3 on page 161) lets you enable service blocking, set up the date and time service blocking is effective, and to maintain the list of services you want to block.14.1.2  What You Need to KnowThe following terms and concepts may help as you read through this chapter.About the WiMAX Modem FirewallThe WiMAX Modem firewall is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated. The WiMAX Modem's purpose is to allow a private Local Area Network (LAN) to be securely connected to
Chapter 14The Firewall ScreensUser s Guide158the Internet. The WiMAX Modem can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The WiMAX Modem is installed between the LAN and a WiMAX base station connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.The WiMAX Modem has one Ethernet (LAN) port. The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, “inbound access” is not allowed (by default) unless the remote host is authorized to use a specific service.14.2  Firewall SettingThis section describes firewalls and the built-in WiMAX Modem’s firewall features.14.2.1  Firewall Rule DirectionsFigure 68   Firewall Rule DirectionsLAN-to-WAN rules are local network to Internet firewall rules. The default is to forward all traffic from your local network to the Internet. You can block certain LAN-to-WAN traffic in the Services screen (click the Services tab). All services displayed in the Blocked Services list box are LAN-to-WAN firewall rules that block those services originating from the LAN. Blocked LAN-to-WAN packets are considered alerts. Alerts are “higher priority logs” that include system errors, attacks and attempted access to blocked web sites. Alerts appear in red in the View Log screen. You may choose to have alerts e-mailed immediately in the Log Settings screen.
 Chapter 14The Firewall ScreensUser s Guide 159LAN-to-LAN/WiMAX Modem means the LAN to the WiMAX Modem LAN interface. This is always allowed, as this is how you manage the WiMAX Modem from your local computer.WAN-to-LAN rules are Internet to your local network firewall rules. The default is to block all traffic from the Internet to your local network. How can you forward certain WAN to LAN traffic? You may allow traffic originating from the WAN to be forwarded to the LAN by:•Configuring NAT port forwarding rules.•Configuring WAN or LAN & WAN access for services in the Remote MGMTscreens or SMT menus. When you allow remote management from the WAN, you are actually configuring WAN-to-WAN/WiMAX Modem firewall rules. WAN-to-WAN/WiMAX Modem firewall rules are Internet to the WiMAX Modem WAN interface firewall rules. The default is to block all such traffic. When you decide what WAN-to-LAN packets to log, you are in fact deciding what WAN-to-LANand WAN-to-WAN/WiMAX Modem packets to log. Forwarded WAN-to-LAN packets are not considered alerts.14.2.2  Triangle RouteWhen the firewall is on, your WiMAX Modem acts as a secure gateway between your LAN and the Internet. In an ideal network topology, all incoming and outgoing network traffic passes through the WiMAX Modem to protect your LAN against attacks.Figure 69   Ideal Firewall Setup

Chapter 14The Firewall ScreensUser s Guide16214.4  Technical ReferenceThe following section contains additional technical information about the WiMAX Modem features described in this chapter.14.4.1  Stateful Inspection Firewall.Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises.Blocked Services This is a list of services (ports) that are inaccessible to computers on your LAN when service blocking is effective.

 Chapter 14The Firewall ScreensUser s Guide 16314.4.2  Guidelines For Enhancing Security With Your Firewall1Change the default password via web configurator.2Think about access control before you connect to the network in any way.3Limit who can access your router.4Don't enable any local service (such as Telnet or FTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network.5For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces.6Protect against IP spoofing by making sure the firewall is active.7Keep the firewall in a secured (locked) room.14.4.3  The “Triangle Route” ProblemA traffic route is a path for sending or receiving data packets between two Ethernet devices. You may have more than one connection to the Internet (through one or more ISPs). If an alternate gateway is on the LAN (and its IP address is in the same subnet as the WiMAX Modem’s LAN IP address), the “triangle route” (also called asymmetrical route) problem may occur. The steps below describe the “triangle route” problem. 1A computer on the LAN initiates a connection by sending out a SYN packet to a receiving server on the WAN.2The WiMAX Modem reroutes the SYN packet through Gateway Aon the LAN to the WAN. 3The reply from the WAN goes directly to the computer on the LAN without going through the WiMAX Modem.
Chapter 14The Firewall ScreensUser s Guide164As a result, the WiMAX Modem resets the connection, as the connection has not been acknowledged.Figure 72   !Triangle Route" Problem14.4.3.1  Solving the “Triangle Route” ProblemIf you have the WiMAX Modem allow triangle route sessions, traffic from the WAN can go directly to a LAN computer without passing through the WiMAX Modem and its firewall protection. Another solution is to use IP alias. IP alias allows you to partition your network into logical sections over the same Ethernet interface. Your WiMAX Modem supports up to three logical LAN interfaces with the WiMAX Modem being the gateway for each logical network. It’s like having multiple LAN networks that actually use the same physical cables and ports. By putting your LAN and Gateway A in different subnets, all returning network traffic must pass through the WiMAX Modem to your LAN. The following steps describe such a scenario.1A computer on the LAN initiates a connection by sending a SYN packet to a receiving server on the WAN. 2The WiMAX Modemreroutes the packet to Gateway A, which is in Subnet 2. 3The reply from the WAN goes to the WiMAX Modem.

Chapter 16The Remote Management ScreensUser s Guide176The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects. The WiMAX Modem supports MIB II that is defined in RFC-1213 and RFC-1215. The focus of the MIBs is to let administrators collect statistical data and monitor status and performance.SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations: •Get - Allows the manager to retrieve an object variable from the agent. •GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. •Set - Allows the manager to set values for object variables within an agent. •Trap - Used by the agent to inform the manager of some events.16.5.1  SNMP TrapsThe WiMAX Modem sends traps to the SNMP manager when any of the following events occurs:          Table 67   SNMP TrapsTRAP # TRAP NAME DESCRIPTION0coldStart (defined in RFC-1215)A trap is sent after booting (power on).1warmStart (defined in RFC-1215)A trap is sent after booting (software reboot).4 authenticationFailure (defined in RFC-1215)A trap is sent to the manager when receiving any SNMP get or set requirements with the wrong community (password).6whyReboot  A trap is sent with the reason of restart before rebooting when the system is going to restart (warm start).6a For intentional reboot: A trap is sent with the message "System reboot by user!" if reboot is done intentionally, (for example, download new files, CI command "sys reboot", etc.).6b For fatal error:  A trap is sent with the message of the fatal code if the system reboots because of fatal errors.

If an outside user attempts to probe an unsupported port on your WiMAX Modem, an ICMP response packet is automatically returned. This allows the outside user to know the WiMAX Modem exists. Your WiMAX Modem supports anti-probing, which prevents the ICMP response packet from being sent. This keeps outsiders from discovering your WiMAX Modem when unsupported ports are probed.If you clear this, your WiMAX Modem replies with an ICMP Port Unreachable packet for a port probe on unused UDP ports and with a TCP Reset packet for a port probe on unused TCP ports.

Chapter 16The Remote Management ScreensUser s Guide18016.8  CWMP-TR069TR-069 is an abbreviation of “Technical Reference 069”, a protocol designed to facilitate the remote management of Customer Premise Equipement (CPE), such as the WiMAX Modem. It can be managed over a WAN by means of an Auto Configuration Server (ACS). TR-069 is based on sending Remote Procedure Calls (RPCs) between the ACS and the client device. RPCs are sent in Extensible Markup Language (XML) format over HTTP or HTTPS. An administrator can use an ACS to remotely set up the WiMAX Modem, modify its settings, perform firmware upgrades, and monitor and diagnose it. In order to do so, you must enable the TR-069 feature on your WiMAX Modem and then configure it appropriately. (The ACS server which it will use must also be configured by its administrator.)Figure 83   TR-069 ExampleIn this example, the WiMAX Modem receives data from at least 3 sources: A SIP server for handling voice calls, an HTTP server for handling web services, and an ACS, for configuring the WiMAX Modem remotely. All three servers are owned and operated by the client’s Internet Service Provider. However, without the configuration settings from the ACS, the WiMAX Modem cannot access the other two servers. Once the WiMAX Modem receives its configuration settings and implements them, it can connect to the other servers. If the settings change, it will once again be unable to connect until it receives its updates from the ACS.The WiMAX Modem can be configured to periodically check for updates from the auto-configuration server so that the end user need not be worried about it.SIPACSHTTP

If you do not enable this feature then the WiMAX Modem can only be updated automatically when the ACS initiates contact with it and if you selected the Active checkbox on this screen.Periodic Inform IntervalEnter the time interval (in seconds) at which the WiMAX Modem connects to the auto-configuration server.Periodic Inform Time Enter a time interval that the WiMAX Modem will trigger a periodic inform interval. This works in tandem with the Periodic Inform Interval and is not mutually exclusive of it.The Periodic Inform Time must be in the following format: yyyy-mm-ddThh:mm:ss where yyyy is a four digit year (“2009”), mm is a two digit month (01~12), dd is a two digit day (01~28), hh is a two-digit hour in 24-hour format (01~24), mm is a two digit minutes value (01-60) and ss is a two digit seconds value (01-60).Note: You must separate the day information from the hour information with a !T".This feature gives the WiMAX Modem abaseline from which to begin calculating when each periodic inform happens. If the inform time is set for some point in the past, the WiMAX Modem interpolates the inform interval forward to the current time and begins its periodic inform at the appropriate time based on this interpolation.If the inform time is set for some point in the future, then the WiMAX Modem interpolates backwards to the current time and actually begins at the appropriate time based on this interpolation.Apply Click to save your changes.Reset Click to restore your previously saved settings.Table 71   TOOLS > Remote Management > CWMP-TR069LABEL DESCRIPTION
User s Guide 183CHAPTER 17QoS17.1  OverviewQuality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and the networking methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical application such as video-on-demand.17.2  GeneralClick TOOLS > QoS to open the screen as shown next.

A classifier groups traffic into data flows according to specific criteria such as the source address, destination address, source port number, destination port number or incoming interface. For example, you can configure a classifier to select traffic from the same protocol port (such as Telnet) to form a flow.You can give different priorities to traffic that the WiMAX Modem forwards out through the WAN interface. Give high priority to voice and video to make them run more smoothly. Similarly, give low priority to many large file downloads so that they do not reduce the quality of other applications.

Some categories such as System Errors consist of both logs and alerts.Syslog LogsThere are two types of syslog: event logs and traffic logs. The device generates an event log when a system event occurs, for example, when a user logs in or the device is under attack. The device generates a traffic log when a "session" is terminated. A traffic log summarizes the session's type, when it started and stopped the amount of traffic that was sent and received and so on. An external log analyzer
Chapter 18The Logs ScreensUser s Guide188can reconstruct and analyze the traffic flowing through the device after collecting the traffic logs. The following table shows RFC-2408 ISAKMP payload types that the log displays. Please refer to the RFC for detailed information on each type.

WiMAX (Worldwide Interoperability for Microwave Access) is a wireless networking standard providing high-bandwidth, wide-range secured wireless service. The WiMAX Modem is a WiMAX mobile station (MS) compatible with the IEEE 802.16e standard.FirewallThe WiMAX Modem is a stateful inspection firewall with DoS (Denial of Service) protection. By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the LAN. The WiMAX Modem’s firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts, reports and logs.Content FilteringThe WiMAX Modem can block access to web sites containing specified keywords. You can define time periods and days during which content filtering is enabled and include or exclude a range of users on the LAN from content filtering.Network Address Translation (NAT) Network Address Translation (NAT) allows the translation of an Internet protocoladdress used within one network (for example a private IP address used in a local network) to a different IP address known withinanother network (for example a public IP address used on the Internet).Dynamic DNS SupportWith Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to be more easily accessible from various locations on the Internet. You must register for this service with a Dynamic DNS service provider.Table 102   Radio Specifications (continued)
 Chapter 21Product SpecificationsUser s Guide 225DHCPDHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. Your device has built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP clients. IP AliasIP alias allows you to partition a physical network into logical networks over the same Ethernet interface. Your device supports three logical LAN interfaces via its single physical Ethernet interface with the your device itself as the gateway for each LAN network.Multiple SIP AccountsYou can configure multiple voice (SIP) accounts.SIP ALGYour device is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass through NAT for devices behind it (such as a SIP-based VoIP software application on a computer).Dynamic Jitter BufferThe built-in adaptive buffer helps to smooth out the variations in delay (jitter) for voice traffic (up to 60 ms). This helps ensure good voice quality for your conversations.Voice Activity Detection/Silence Suppression Voice Activity Detection (VAD) reduces the bandwidth that a call uses by not transmitting when you are not speaking. Comfort Noise GenerationYour device generates background noise to fill moments of silence when the other device in a call stops transmitting because the other party is not speaking (as total silence could easily be mistaken for a lost connection). Echo Cancellation You device supports G.168 of at least 24 ms.This an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk.Time and DateGet the current time and date from an external server when you turn on your WiMAX Modem.

The caller must still pay while the call is parked.When you park the call, you enter a number of your choice (up to eight digits), which you must enter again when you pick up the call. If you do not enter the correct number, you cannot pickup the call. This means that only someone who knows the number you have chosen can pick up the call. You can have more than one call on hold at the same time, but you must give each call a different number.Call ReturnWith call return, you can place a call to the last number that called you (either answered or missed). The last incoming call can be through either SIP or PSTN.Country CodePhone standards and settings differ from one country to another, so the settings on your WiMAX Modem must be configured to match those of the country you are in. The country code feature allows you to do this by selecting the country from a list rather than changing each setting manually. Configure the country code feature when you move the WiMAX Modem from one country to another.Do not Disturb (DnD) This feature allows you to set your phone not to ring when someone calls you. You can set each phone independently using its keypad, or configure global settings for all phones using the command line interpreter.Auto DialYou can set the WiMAX Modem to automatically dial a specified number immediately whenever you lift a phone off the hook. Use the Web Configurator to set the specified number. Use the command line interpreter to have the WiMAX Modem wait a specified length of time before dialing the number. Phone configThe phone configuration table allows you to customize the phone keypad combinations you use to access certain features on the WiMAX Modem, such as call waiting, call return, call forward, etc. The phone configuration table is configurable in command interpreter mode.Firmware update enable / disable If your service provider uses this feature, you hear a recorded message when you pick up the phone when new firmware is available for your WiMAX Modem. Enter *99# in your phone’s keypad to have the WiMAX Modem upgrade the firmware, or enter #99# to not upgrade. If your service provider gave you different numbers to use, enter them instead. If you enter the code to not upgrade, you can make a call as normal. You will hear the recording again each time you pick up the phone, until you upgrade. Table 104   Standards Supported  (continued)STANDARD DESCRIPTION

User s Guide 231APPENDIX  A WiMAX SecurityWireless security is vital to protect your wireless communications. Without it, information transmitted over the wireless network would be accessible to any networking device within range.User Authentication and Data EncryptionThe WiMAX (IEEE 802.16) standard employs user authentication and encryption to ensure secured communication at all times.User authentication is the process of confirming a user’s identity and level of authorization. Data encryption is the process of encoding information so that it cannot be read by anyone who does not know the code. WiMAX uses PKMv2 (Privacy Key Management version 2) for authentication, and CCMP (Counter Mode with Cipher Block Chaining Message Authentication Protocol) for data encryption. WiMAX supports EAP (Extensible Authentication Protocol, RFC 2486) which allows additional authentication methods to be deployed with no changes to the base station or the mobile or subscriber stations.PKMv2PKMv2 is a procedure that allows authentication of a mobile or subscriber station and negotiation of a public key to encrypt traffic between the MS/SS and the base station. PKMv2 uses standard EAP methods such as Transport Layer Security (EAP-TLS) or Tunneled TLS (EAP-TTLS) for secure communication. In cryptography, a ‘key’ is a piece of information, typically a string of random numbers and letters, that can be used to ‘lock’ (encrypt) or ‘unlock’ (decrypt) a message. Public key encryption uses key pairs, which consist of a public (freely available) key and a private (secret) key. The public key is used for encryption and the private key is used for decryption. You can decrypt a message only if you have the private key. Public key certificates (or ‘digital IDs’) allow users to verify each other’s identity.
Appendix AWiMAX SecurityUser s Guide232RADIUSRADIUS is based on a client-server model that supports authentication, authorization and accounting. The base station is the client and the server is the RADIUS server. The RADIUS server handles the following tasks:•Authentication Determines the identity of the users.•AuthorizationDetermines the network services available to authenticated users once they are connected to the network.•AccountingKeeps track of the client’s network activity. RADIUS is a simple package exchange in which your base station acts as a message relay between the MS/SS and the network RADIUS server. Types of RADIUS MessagesThe following types of RADIUS messages are exchanged between the base station and the RADIUS server for user authentication:•Access-RequestSent by an base station requesting authentication.•Access-RejectSent by a RADIUS server rejecting access.•Access-AcceptSent by a RADIUS server allowing access. •Access-ChallengeSent by a RADIUS server requesting more information in order to allow access. The base station sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the base station and the RADIUS server for user accounting:•Accounting-RequestSent by the base station requesting accounting.•Accounting-ResponseSent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password they both know. The key is not sent over
 Appendix AWiMAX SecurityUser s Guide 233the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. DiameterDiameter (RFC 3588) is a type of AAA server that provides several improvements over RADIUS in efficiency, security, and support for roaming. Security AssociationThe set of information about user authentication and data encryption between two computers is known as a security association (SA). In a WiMAX network, the process of security association has three stages.•Authorization request and replyThe MS/SS presents its public certificate to the base station. The base station verifies the certificate and sends an authentication key (AK) to the MS/SS.•Key request and replyThe MS/SS requests a transport encryption key (TEK) which the base station generates and encrypts using the authentication key. •Encrypted trafficThe MS/SS decrypts the TEK (using the authentication key). Both stations can now securely encrypt and decrypt the data flow.CCMPAll traffic in a WiMAX network is encrypted using CCMP (Counter Mode with Cipher Block Chaining Message Authentication Protocol). CCMP is based on the 128-bit Advanced Encryption Standard (AES) algorithm. ‘Counter mode’ refers to the encryption of each block of plain text with an arbitrary number, known as the counter. This number changes each time a block of plain text is encrypted. Counter mode avoids the security weakness of repeated identical blocks of encrypted text that makes encrypted data vulnerable to pattern-spotting.‘Cipher Block Chaining Message Authentication’ (also known as CBC-MAC) ensures message integrity by encrypting each block of plain text in such a way that its encryption is dependent on the block before it. This series of ‘chained’ blocks creates a message authentication code (MAC or CMAC) that ensures the encrypted data has not been tampered with.
Appendix AWiMAX SecurityUser s Guide234AuthenticationThe WiMAX Modem supports EAP-TTLS authentication.EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection (with EAP-TLS digital certifications are needed by both the server and the wireless clients for mutual authentication). Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2.

User s Guide 273APPENDIX  D IP Addresses and SubnettingThis appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts.Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.Introduction to IP AddressesOne part of the IP address is the network number, and the other part is the host ID. In the same way that houses on a street share a common street name, the hosts on a network share a common network number. Similarly, as each house has its own house number, each host on the network has its own unique identifying number - the host ID. Routers use the network number to send packets to the correct network, while the host ID determines to which host on the network the packets are delivered.StructureAn IP address is made up of four parts, written in dotted decimal notation (for example, 192.168.1.1). Each of these four parts is known as an octet. An octet is an eight-digit binary number (for example 11000000, which is 192 in decimal notation). Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal.
Appendix DIP Addresses and SubnettingUser s Guide274The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID.Figure 146   Network Number and Host IDHow much of the IP address is the network number and how much is the host ID varies according to the subnet mask.  Subnet MasksA subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term “subnet” is short for “sub-network”.A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the corresponding bit in the IP address is part of the network number. If a bit in the subnet mask is “0” then the corresponding bit in the IP address is part of the host ID. The following example shows a subnet mask identifying the network number (in bold text) and host ID of an IP address (192.168.1.2 in decimal).Table 107   IP Address Network Number and Host ID Example1STOCTET:(192)2NDOCTET:(168)3RDOCTET:(1)4TH OCTET(2)IP Address (Binary)11000000101010000000000100000010Subnet Mask (Binary) 111111111111111111111111 00000000Network Number 110000001010100000000001Host ID00000010
 Appendix DIP Addresses and SubnettingUser s Guide 275By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.Subnet masks can be referred to by the size of the network number part (the bits with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes.Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks. Network SizeThe size of the network number determines the maximum number of possible hosts you can have on your network. The larger the number of network number bits, the smaller the number of remaining host ID bits. An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 with a 24-bit subnet mask, for example). An IP address with host IDs of all ones is the broadcast address for that network  (192.168.1.255 with a 24-bit subnet mask, for example).As these two IP addresses cannot be used for individual hosts, calculate the maximum number of possible hosts in a network as follows:Table 108   Subnet MasksBINARYDECIMAL1STOCTET2NDOCTET3RDOCTET4THOCTET8-bit mask 11111111 00000000 00000000 00000000 255.0.0.016-bitmask 11111111 11111111 00000000 00000000 255.255.0.024-bitmask 11111111 11111111 11111111 00000000 255.255.255.029-bitmask 11111111 11111111 11111111 11111000 255.255.255.248Table 109   Maximum Host NumbersSUBNET MASK HOST ID SIZE MAXIMUM NUMBER OF HOSTS8 bits255.0.0.024 bits224 – 21677721416 bits255.255.0.016 bits216 – 26553424 bits255.255.255.08 bits28 – 225429 bits255.255.255.248 3 bits23 – 26
Appendix DIP Addresses and SubnettingUser s Guide276NotationSince the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/” followed by the number of bits in the mask after the address. For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128. The following table shows some possible subnet masks using both notations. SubnettingYou can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons.In this example, the company network address is 192.168.1.0. The first three octets of the address (192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum of 28 – 2 or 254 possible hosts.Table 110   Alternative Subnet Mask NotationSUBNET MASKALTERNATIVE NOTATIONLAST OCTET (BINARY)LAST OCTET (DECIMAL)255.255.255.0 /24 0000 0000 0255.255.255.128/25 1000 0000 128255.255.255.192/26 1100 0000 192255.255.255.224/27 1110 0000 224255.255.255.240/28 1111 0000 240255.255.255.248/29 1111 1000 248255.255.255.252/30 1111 1100 252
 Appendix DIP Addresses and SubnettingUser s Guide 277The following figure shows the company network before subnetting.  Figure 147   Subnetting Example: Before SubnettingYou can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or /25).The “borrowed” host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25.
Appendix DIP Addresses and SubnettingUser s Guide278The following figure shows the company network after subnetting. There are now two sub-networks, A and B.Figure 148   Subnetting Example: After SubnettingIn a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address).192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126. Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.Example: Four Subnets The previous example illustrated using a 25-bit subnet mask to divide a 24-bit address into two subnets. Similarly, to divide a 24-bit address into four subnets, you need to “borrow” two host ID bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192.
 Appendix DIP Addresses and SubnettingUser s Guide 279Each subnet contains 6 host ID bits, giving 26 - 2 or 62 hosts for each subnet (a host ID of all zeroes is the subnet itself, all ones is the subnet’s broadcast address).

 Appendix DIP Addresses and SubnettingUser s Guide 281The following table is a summary for subnet planning on a network with a 16-bit network number. Configuring IP AddressesWhere you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. You must also enable Network Address Translation (NAT) on the WiMAX Modem. Once you have decided on the network number, pick an IP address for your WiMAX Modem that is easy to remember (for instance, 192.168.1.1) but make sure that no other device on your network is using that IP address.The subnet mask specifies the network number portion of an IP address. Your WiMAX Modem will compute the subnet mask automatically based on the IP Table 117   16-bit Network Number Subnet PlanningNO. “BORROWED” HOST BITS SUBNET MASK NO. SUBNETS NO.

Appendix DIP Addresses and SubnettingUser s Guide282address that you entered. You don't need to change the subnet mask computed by the WiMAX Modem unless you are instructed to do otherwise.Private IP AddressesEvery machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only between two branch offices, for example) you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks:•10.0.0.0     — 10.255.255.255•172.16.0.0   — 172.31.255.255•192.168.0.0 — 192.168.255.255You can obtain your IP address from the IANA, from an ISP, or it can be assigned from a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses.Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.IP Address ConflictsEach device on a network must have a unique IP address. Devices with duplicate IP addresses on the same network will not be able to access the Internet or other resources. The devices may also be unreachable through the network. Conflicting Computer IP Addresses ExampleMore than one device can not use the same IP address. In the following example computer Ahas a static (or fixed) IP address that is the same as the IP address that a DHCP server assigns to computer B which is a DHCP client. Neither can access the Internet. This problem can be solved by assigning a different static IP
 Appendix DIP Addresses and SubnettingUser s Guide 283address to computer A or setting computer A to obtain an IP address automatically.  Figure 149   Conflicting Computer IP Addresses ExampleConflicting Router IP Addresses ExampleSince a router connects different networks, it must have interfaces using different network numbers. For example, if a router is set between a LAN and the Internet (WAN), the router’s LAN and WAN addresses must be on different subnets. In the following example, the LAN and WAN are on the same subnet. The LAN computers cannot access the Internet because the router cannot route between networks.Figure 150   Conflicting Computer IP Addresses ExampleConflicting Computer and Router IP Addresses ExampleMore than one device can not use the same IP address.

User s Guide 285APPENDIX  E Importing CertificatesThis appendix shows you how to import public key certificates into your web browser. Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few, receives a certificate request from a website operator, they confirm that the web domain and contact information in the request match those on public record with a domain name registrar. If they match, then the certificate is issued to the website operator, who then places it on the site to be issued to all visiting web browsers to let them know that the site is legitimate.Many products issue their own public key certificates. These can be used by web browsers on a LAN or WAN to verify that they are in fact connecting to the legitimate device and not one masquerading as it. However, because the certificates were not issued by one of the several organizations officially recognized by the most common web browsers, you will need to import the certificate into your web browser and flag that certificate as a trusted authority.Note: You can see if you are browsing on a secure website if the URL in your web browser s address bar begins with  https:// or there is a sealed padlock icon () somewhere in the main browser window (not all browsers show the padlock in the same location.)In this appendix, you can import a public key certificate for:•Internet Explorer on page 286•Firefox on page 296•Opera on page 302•Konqueror on page 310

User s Guide 315APPENDIX  F  SIP PassthroughEnabling/Disabling the SIP ALGYou can turn off the WiMAX Modem SIP ALG to avoid retranslating the IP address of an existing SIP device that is using STUN. If you want to use STUN with a SIP client device (a SIP phone or IP phone for example) behind the WiMAX Modem, use the ip alg disable ALG_SIP command to turn off the SIP ALG.Signaling Session TimeoutMost SIP clients have an “expire” mechanism indicating the lifetime of signaling sessions. The SIP UA sends registration packets to the SIP server periodically and keeps the session alive in the WiMAX Modem. If the SIP client does not have this mechanism and makes no call during the WiMAX Modem SIP timeout default (60 minutes), the WiMAX Modem SIP ALG drops any incoming calls after the timeout period. You can use the ip alg siptimeout command to change the timeout value.Audio Session TimeoutIf no voice packets go through the SIP ALG before the timeout period default (5 minutes) expires, the SIP ALG does not drop the call but blocks all voice traffic and deletes the audio session. You cannot hear anything and you will need to make a new call to continue your conversation.
