Introducing MultiVoice Gateway concepts What is MultiVoice for the MAX? In addition to data, packets contain addressing information, which routing devices use to send information to its destination. Routing devices maintain tables which instruct them how to direct packets. Dynamic protocols, like RIP or OSPF, define methods that routing devices use to update each other as networking environments change. In the past, the PSTN was the only network supporting voice communication.
Introducing MultiVoice Gateway concepts What is MultiVoice for the MAX? 3 MultiVoice Gateway 1 forwards the phone number and PIN authentication to the MultiVoice Access Manager. 4 The Gatekeeper authenticates Caller A and, if successful, forwards the IP address of MultiVoice Gateway 2 to MultiVoice Gateway 1. 5 MultiVoice Gateway 1 establishes a session with MultiVoice Gateway 2. 6 MultiVoice Gateway 2 forwards the call request to Caller B.
Introducing MultiVoice Gateway concepts What is MultiVoice for the MAX? As illustrated in Figure 1-3, two MultiVoice Gateways connect Caller A to Caller B. Either of the systems running the MultiVoice Access Manager can be the Gatekeeper. Figure 1-3.
Introducing MultiVoice Gateway concepts What is MultiVoice for the MAX? • The MultiVoice Gateway goes into a slow poll mode, in which it attempts to register with the primary Gatekeeper at 30-second intervals, if no valid IP address is configured for the 2nd GK IP parameter. Reregistration policy Once the MultiVoice Gateway registers with the secondary Gatekeeper, it periodically attempts to reregister with the primary Gatekeeper.
Introducing MultiVoice Gateway concepts What is MultiVoice for the MAX? Figure 1-4 shows an example of a MultiVoice network using overlapping coverage areas. Two Gateways provide coverage to area code 516. The MultiVoice Access Manager is the Gatekeeper. Figure 1-4.
Introducing MultiVoice Gateway concepts What is MultiVoice for the MAX? Since one DSP can only process one call at a time, the Gatekeeper will attempt to assign calls to each MultiVoice Gateway based upon DSP availability, alternating call assignments between covering Gateways.
Introducing MultiVoice Gateway concepts MultiVoice applications MultiVoice applications MultiVoice supports a variety of applications, including: • Basic public long-distance service • Local 800 service • Point-to-Point Private Branch Exchange (PBX) trunk extensions • PBX trunk intraflow • PC-to-phone over a VPN Basic public long-distance service Basic public long-distance service is the most beneficial to Competitive Local Exchange Carriers (CLECs) and Internet Service Providers (ISPs) that: •

Introducing MultiVoice Gateway concepts MultiVoice applications This architecture can also support PBX intraflow. The PBX can be configured to routes calls to the alternative path when all trunks between PBXs are in use. PBX intraflow reduces the number of inter-PBX trunks the company needs, while ensuring that users can make calls even during busy periods. PC-to-Phone calls Figure 1-10 shows how to PC-to-Phone calls could be connected using either a virtual private network (VPN) or an ISP’s PoP.

Configuring the WAN Interfaces Configuring T1 lines • ISDN NFAS (Non-Facility Associated signalling)—Enables two or more T1 lines to share a D channel. One of the lines must be configured as the primary D channel and one as the secondary (backup) D channel. Assigning an interface ID to NFAS lines The NFAS ID Num is a different interface ID for each NFAS line. In most cases, the default 1 for the first line and 2 for the second line are correct.
Configuring the WAN Interfaces Configuring T1 lines You cannot use FDL reporting on a line configured for D4 framing. However, you can obtain D4 and ESF performance statistics in the FDL Stats windows, even if you do not choose an FDL protocol. Cable length and the amount of attenuation required The Length parameter specifies the length of the physical T1 line in feet from the external Channel Service Unit (CSU) to the MultiVoice Gateway.

Configuring IP Routing Introduction to IP routing and interfaces For example, a class C address such as 198.5.248.40 has 24 network bits, so its default mask is 24. The 24 network bits leave 8 bits for the host portion of the address. So one class C network can support up to 253 hosts. Figure 8-1. A class C IP address 11111111111111111111111100000000 Default 24 bits As shown in Table 8-1, a mask has a binary 1 in each masked position.
Configuring IP Routing Introduction to IP routing and interfaces Zero subnets Early implementations of TCP/IP did not allow zero subnets. That is, subnets could have the same base address that a class A, B, or C network would have. For example, the subnet 192.168.8.0/30 was illegal because it had the same base address as the class C network 192.168.8.0/24, while 192.168.8.4/30 was legal (192.168.8.0/30 is called a zero subnet, because like a class C base address, its last octet is zero).
Configuring IP Routing Introduction to IP routing and interfaces IP routes At system start-up, the MultiVoice Gateway builds an IP routing table that contains configured routes. When the system is up, it can use routing protocols such as RIP or OSPF to learn additional routes dynamically. In each routing table entry, the Destination field specifies a destination network address that may appear in IP packets, and the Gateway field specifies the address of the next-hop router to reach that destination.
Configuring IP Routing Introduction to IP routing and interfaces the metric fields and uses the route with the lowest metric.
Configuring IP Routing Configuring the local IP network setup Interface Description Multi-cast Have a destination address with a value of 224 for the first octet. The MultiVoice Gateway does not support Multi-casting, and the MultiVoice Gateway ignores Multi-cast entries in its routing table. Configuring the local IP network setup The Ethernet profile contains system-global parameters that affect all IP interfaces in the MultiVoice Gateway.
Configuring IP Routing Configuring the local IP network setup Primary IP address for the Ethernet interface The IP Address parameter specifies the MultiVoice Gateway unit’s IP address for the local Ethernet interface. When specifying IP addresses for the MultiVoice Gateway’s Ethernet interfaces, you must specify the subnet mask. IP address and subnet mask are required settings for the MultiVoice Gateway to operate as an IP router.
Configuring IP Routing Configuring the local IP network setup Enabling RIP on the Ethernet interface You can configure the IP interface to send RIP updates (inform other local routers of its routes), receive RIP updates (learn about networks that can be reached through other routers on the Ethernet), or both. Note: Ascend recommends that you run RIP version 2 (RIP-v2) if possible. You should not run RIP-v2 and RIP-v1 on the same network in such a way that the routers receive each other’s advertisements.
Configuring IP Routing Configuring the local IP network setup Ethernet > Mod Config > TServ Options. SLIP BOOTP makes it possible for a computer connecting to the MultiVoice Gateway over a SLIP connection to use the Bootstrap Protocol. A MultiVoice Gateway can support BOOTP on only one connection. If both SLIP BOOTP and BOOTP relay are enabled, you will receive an error message. You can specify the IP address of one or two BOOTP servers, but you are not required to specify a second BOOTP server.
Configuring IP Routing Configuring the local IP network setup For Frankfurt, which is 1 hour behind UTC, the time would be: UTC -0100 Specifying SNTP server addresses The Host parameter lets you specify up to three server addresses. The MultiVoice Gateway attempts to communicate with the first address. It attempts the second only if the first is inaccessible, and the third only if the second is inaccessible.
Configuring IP Routing Configuring the local IP network setup You can place the MultiVoice Gateway on a subnet of that network by entering a subnet mask in its IP address specification. For example: 1 Open Ethernet > Mod Config > Ether Options. 2 Specify the IP subnet address for the MultiVoice Gateway on Ethernet. For example: Ethernet Mod Config Ether options… IP Adrs=10.2.3.

Configuring IP Routing Configuring the local IP network setup Editing the local DNS table To edit the DNS table entries, you access the DNS table editor from the terminal server. While the editor is in use, the system cannot look up addresses in the table or perform automatic updates. A table entry is one of the eight table indexes. It includes the host name, IP address (or addresses), and information fields.
Configuring IP Routing Configuring IP routes and preferences Configuring IP routes and preferences The IP routing table contains routes that are configured (static routes) and routes that are learned dynamically from routing protocols such as RIP or OSPF. The following example shows the parameters for configuring static routes: Ethernet Static Rtes Name=route-name Active=Yes Dest=10.2.3.0/24 Gateway=10.2.3.
Configuring IP Routing Configuring IP routes and preferences Route’s gateway address The Gateway parameter specifies the IP address of the router or interface through which to reach the target network. Metrics, costs, and preferences The Metric parameter specifies the hop count (a number of from 1 to 15) for this route. Hop count refers to the number of routers that have to be crossed to reach the destination.
Configuring IP Routing Configuring IP routes and preferences Static route preferences By default, static routes and RIP routes have the same preference, so they compete equally. ICMP redirects take precedence over both, and OSPF take precedence over everything. If a dynamic route’s preference is lower than that of the static route, the dynamic route can overwrite (hide) a static route to the same network. In the IP routing table, the hidden static route has an h flag, indicating that it is inactive.
Configuring IP Routing Configuring IP routes and preferences Active=Yes Dest=0.0.0.0/0 Note: The name of the first IP Route profile is always Default, and its destination is always 0.0.0.0 (you cannot change these values). 2 Specify the router to use for packets with unknown destinations. For example: Gateway=10.9.8.10 3 Specify a metric for this route, the route’s preference, and whether the route is private. For example: Metric=1 Preference=100 Private=Yes 4 Close the IP Route profile.
Configuring IP Routing Configuring the MultiVoice Gateway for dynamic route updates Example of route preferences configuration The following example increases the preference value of RIP routes, instructing the router to use a static route first if one exists. 1 Open Ethernet > Mod Config > Route Pref. 2 Set Rip Preference to 150: Ethernet Mod Config Route Pref… Rip Preference=150 3 Close the Ethernet profile.
Configuring IP Routing Configuring the MultiVoice Gateway for dynamic route updates Ignoring the default route You can configure the MultiVoice Gateway to ignore default routes advertised by routing protocols. This configuration is recommended, because you typically do not want the default route changed by a RIP update. The default route specifies a static route to another IP router, which is often a local router such as a Cisco router or another kind of LAN router.

Configuring OSPF Routing Introduction to OSPF Problem Description and solution Excessive routing traffic and slow convergence RIP creates a routing table and then propagates it throughout the internet of routers, hop by hop. The time it takes for all routers to receive information about a topology change is called convergence. A slow convergence can result in routing loops and errors. A RIP router broadcasts its entire routing table every 30 seconds. On a 15-hop network, convergence can be as high as 7.
Configuring OSPF Routing Introduction to OSPF Security All OSPF protocol exchanges are authenticated. This means that only trusted routers can participate in the AS’s routing. A variety of authentication schemes are available. In fact, different authentication types can be configured for each area. In addition, authentication provides added security for the routers that are on the network.
Configuring OSPF Routing Introduction to OSPF Exchange of routing information OSPF uses a topological database of the network and propagates only changes to the database. Part of the SPF algorithm involves acquiring neighbors, then forming an adjacency with one neighbor, as shown in Figure 9-2. Figure 9-2. Adjacency between neighboring routers An OSPF router dynamically detects its neighboring routers by sending its Hello packets to the multicast address All SPFRouters.
Configuring OSPF Routing Introduction to OSPF dedicate the MultiVoice Gateway to WAN processing. The administrator chooses a DR and BDR on the basis of the device’s processing power and reliability. To reduce the number of adjacencies each router must form, OSPF calls one of the routers the designated router. A designated router is elected as routers are forming adjacencies, and then all other routers establish adjacencies only with the designated router.
Configuring OSPF Routing Introduction to OSPF example, for a single B-channel connection, the cost would be 24 times greater than for a T1 link. Note: Be careful when assigning costs. Incorrect cost metrics can cause delays and congestion on the network. Hierarchical routing (areas) If a network is large, the size of the database, time required for route computation, and related network traffic become excessive.
Configuring OSPF Routing Introduction to OSPF In a stub area, routing to AS-external destinations is based on a per-area default cost. The per-area default cost is advertised to all routers within the stub area by a border router, and is used for all external destinations. If the MultiVoice Gateway supports external routes across its WAN links, you should not configure it in a stub area.
Configuring OSPF Routing Introduction to OSPF 6 Refer to the documentation that came with your MultiVoice Gateway. 7 In this static route profile, specify whether you want to advertise this route outside the NSSA: – To advertise this route outside the NSSA, set NSSA-Type to Advertise. – To not advertise this route outside the NSSA, set NSSA-Type to DoNotAdvertise. 8 Exit and save the Static Rtes profile. 9 Reset the MultiVoice Gateway.
Configuring OSPF Routing Introduction to OSPF separate from the Link-state data. Also, each external route can be tagged by the advertising router, enabling the passing of additional information between routers on the boundary of the AS. Table 9-2.

Configuring OSPF Routing Configuring OSPF routing in the MultiVoice Gateway Parameters Description Priority Value used by the routers in the network to elect a Designated Router (DR) and Backup Designated Router (BDR). Assigning a priority of 1 would place the MultiVoice Gateway near the top of the list of possible designated routers. (Currently, you should assign a larger number.) Acting as a DR or BDR significantly increases the amount of OSPF overhead for the router.
Configuring OSPF Routing Configuring OSPF routing in the MultiVoice Gateway Example of configuration adding the MultiVoice Gateway to an OSPF network This section describes how to add a MultiVoice Gateway to your OSPF network. It assumes that you know how to configure the MultiVoice Gateway with an appropriate IP address as described in Chapter 8, “Configuring IP Routing.” The procedures in this section are examples based on Figure 9-7.
Configuring OSPF Routing Configuring OSPF routing in the MultiVoice Gateway RIP=Off Ignore Def Rt=Yes Proxy Mode=Always Filter=0 IPX Frame=N/A Note that RIP is turned off. It is not necessary to run both RIP and OSPF, and turning RIP off reduces processor overhead. OSPF can learn routes from RIP, incorporate them in the routing table, assign them an external metric, and tag them as external routes. (For more information, see Chapter 8, “Configuring IP Routing.
Configuring OSPF Routing Administering OSPF Administering OSPF This section describes how to work with OSPF information in the routing table and how to monitor OSPF activity in the terminal-server command-line interface. To invoke the terminal-server interface, select System > Sys Diag > Term Serv and press Enter. Working with the routing table The OSPF routing table includes routes built from the router’s link-state database as well as those added by external routing protocols such as RIP.
Configuring OSPF Routing Administering OSPF Multipath routing A MAX running OSPF can alternate between two equal cost gateways. When OSPF detects more than one equally good gateway, in terms of routing costs, each equal-cost gateway is put on an equal-cost list. The router will alternate between all the gateways on the list. This is called equal-cost multipath routing. For example, if router A has two equal-cost routes to example.
Configuring OSPF Routing Administering OSPF The following example shows how to configure a static route for OSPF to advertise a third-party gateway: 1 Open a static route in Ethernet > Static Rtes. 2 Set Third-Party to Yes. 3 Set the Gateway to the forwarding address. Ethernet Static Rtes Name=third-party Silent=No Active=Yes Dest=10.212.65.0/24 Gateway=101.2.3.4 Metric=3 Preference=100 Private=No Ospf-Cost=1 LSA-Type=Type1 ASE-tag=c00000000 Third-Party=Yes 4 Close the static route.
Configuring OSPF Routing Administering OSPF • A statically configured IP Route has a default of Preference=100. You can modify the default in the IP Route profile. When choosing which routes should be put in the routing table, the router first compares the Preference values, preferring the lowest number. If the Preference values are equal, the router compares the Metric field, and uses the route with the lowest Metric.

MultiVoice Gateway System Administration Terminal-server commands To return to the command line, press 0 (zero). Terminal-server security must be set up to allow the operator to toggle between the command line and menu mode, or the Menu command has no effect. Specifying raw TCP hosts To specify IP addresses or DNS names of hosts to which you establish a raw TCP connection, proceed as follows: 1 Open the Ethernet > Mod Config > TServ options menu.
MultiVoice Gateway System Administration Terminal-server commands Telnet command The Telnet command initiates a login session to a remote host. It uses the following format: telnet [-a|-b|–t] hostname [port-number] If DNS is configured in the Ethernet profile, you can specify a hostname: ascend% telnet myhost If you do not configure DNS, you must specify the host’s IP address instead. There are also several options in Ethernet > Mod Config > TServ Options that affect Telnet.
MultiVoice Gateway System Administration Terminal-server commands Telnet session commands The commands in this section can be typed at the Telnet prompt during an open session. To display the Telnet prompt during an active login to the specified host, press Ctrl-] (hold down the Control key and type a right-bracket). To display information about Telnet session commands, use the Help or ? command. For example: telnet> ? To open a Telnet connection after invoking Telnet, use the Open command.
MultiVoice Gateway System Administration Terminal-server commands If DNS has not been configured, you must specify the host’s IP address instead. Rlogin must also be enabled in Ethernet > Mod Config > TServ Options. The arguments to the Rlogin command are: Argument Description hostname If you configure DNS, you can specify the remote system’s hostname. Otherwise, hostname must be the IP address of the remote station. -e char Sets the escape character to char. For example: rlogin -e$ 10.2.3.

Troubleshooting ISDN cause codes ISDN cause codes ISDN cause codes are numerical diagnostic codes sent from an ISDN switch to a DTE. These codes provide an indication of why a call failed to be established or why a call was terminated. The cause codes are part of the ISDN D-channel signaling communications supported by the Signaling System 7 supervisory network (WAN).

(In REL: Call cleared down as a result of local errors; for example, invalid messages or parameters, expiry of timeout. In SUS REJ: The link must not be suspended because another facility is already active. In RES REJ: No suspended call available.
Troubleshooting Common problems and their solutions The MultiVoice Gateway cannot dial out on a T1 or E1 line To verify that a profile is correctly configured: 1 Make certain that you have entered the correct phone number to dial. 2 Verify that the Data Svc parameter specifies a WAN service available on your line. If you request a WAN service that is not available on your line, the WAN rejects your request to place a call. 3 Check whether the channels using the requested WAN service are busy.
Troubleshooting Common problems and their solutions 2 Check the flow control settings on your VT100 terminal. If you are not communicating at all with the MultiVoice Gateway, see whether you can establish communication after you have turned off all transmit and receive flow control at your terminal or terminal emulator. 3 Determine whether you need a null-modem cable converter. In general, it is not required for communications to the MultiVoice Gateway.
Troubleshooting Common problems and their solutions If the line interface is not equipped with an internal CSU, the Length parameter is displayed. It can specify a cable length, of 1-133, 134-266, 267-399, 400-533, or 534-655, in feet, which should correspond to the distance between the MultiVoice Gateway and the WAN interface equipment, typically a CSU or multiplexer.
Troubleshooting Common problems and their solutions Four-digit dialing involves the last four digits of your phone number. For example, if your phone number is (415) 555-9015, four-digit dialing requires that you type only the last four digits—9015. Seven-digit dialing specifies that you dial the digits 5559015, and ten-digit dialing requires 4155559015. If you are sending the incorrect number of digits, the MultiVoice Gateway cannot route the call.
Troubleshooting Common problems and their solutions • Check the switch, or PBX. If it cannot pass the DNIS to the Gateway, change the setting on the MultiVoice Gateway for the Single Dial Enable parameter to No. Callers will dial the Gateway and destination telephone numbers separately. • If the switch, or PBX, passes the DNIS to the Gateway, check the switch configuration, and the Gateway configuration. Make sure the Gateway is using the proper settings for the Net/T1 or Net/E1 parameters.
Troubleshooting Common problems and their solutions Change the value to the other available option and check to see whether the Red Alarm condition goes away within 30 seconds. 2 If the Red Alarm state persists, check the cabling. You might have a crossover cable installed when a straight-through cable is required, or vice versa. If the MultiVoice Gateway is connected through bantam plugs, reverse the transmit and receive plugs.
