5 Attaching Brackets to the Rack After the brackets are attached to the router, use the four supplied number-12 Phillips machine screws to securely attach the brackets to the rack, as shown in Figure 3. Caution Make sure that the fans on the side of the chassis are not blocked. Figure 3 Attaching Br...

6 Figure 4 Attaching the Cable Guide to the Router 5 Installing WIC/VIC Cards The router has four card slots that hold Cisco WICs and VICs. Either one or two WICs may be installed, with the remaining slots holding VICs, as desired. If no WICs are present in the slots, up to four VICs may be installe...

7 Caution Do not connect a WAN, telephone or fax cable to the card until you have completed the installation procedure. Card Installation Follow these steps to insert a card in the router: Step 1 Make sure the router is turned off and is disconnected from AC power. Caution Power must be removed from...

8 Note Slots 2 and 3 accept VICs only. These slots have a small metal tab on the right side that interferes with a similar tab on WICs, preventing the insertion of WICs by mistake. Step 6 Tighten the screws that are on the card. Voice Port Verification When the router is connected to a PC and you ar...

9 Warning The ports labeled 10/100-Mbps Ethernet port and Console port are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuits to the telephone net...

10 Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120VAC, 15A U.S. (240VAC, 16A international) is used on the phase conductors (all current-carrying conductors). Warning This equipment needs ...

11 • MOD OK—On when the virtual private network (VPN) module is correctly installed in its slot and is recognized by the system. 8 Connect a PC to the Router Console Port Connect a PC to the router’s console port and establish a console session to view startup messages and verify voice card installa...

12 --- System Configuration Dialog --- At any point you may enter a question mark '?' for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'. Would you like to enter the initial configuration dialog? [yes/no]: To learn how to use the CLI to con...

13 If these messages do not appear, SDM and a default configuration file were installed on the router at the factory. To use SDM to configure the router, see the “Initial Configuration Using Cisco Router and Security Device Manager” section on page 12. Note Be sure to save your configuration changes...

14 10 Use the CLI to Configure VoIP The following sections explain how to set up basic VoIP configurations using the Cisco IOS command line interface (CLI). Note VoIP requires one of the IP/Plus/Voice feature sets from IOS Release 12.2(2)XK, or later. • Information for International Users • Saving t...

15 The router is now configured to start in the new configuration. Configuring the Fast Ethernet Interface To configure the Fast Ethernet interface, follow these steps, beginning in global configuration mode: Configuring a Dial Plan Use a dial plan to map the destination telephone numbers with the v...

16 The destination-pattern command defines the telephone number associated with the VoFR dial peer. The session target command specifies a destination DLCI for the VoFR dial peer. Use the dial-peer voice command to define dial peers and to change to dial peer configuration mode. For examples, see th...

17 • An FXO (foreign exchange office) interface connects local calls to a PSTN central office or to a PBX that does not support E&M signaling. This is the interface a standard telephone provides. Ports on this VIC are pink. • An E&M is a signaling technique for two-wire and four-wire telepho...

18 Note If your router is configured with four 2-port VICs, you can connect a total of eight telephones and fax machines to it. As the router has only four slots, you need to replace one VIC with a WIC to provide an interface for IP connectivity to the WAN and for data traffic. To accommodate more v...

19 West(config)# These commands are summarized in Figure 13. Figure 13 West Router Configured for Local Dial Peers The dial-peer command always takes the argument voice . The number following it is the dial-peer tag, and pots is the type of dial peer. Cisco IOS software refers to a telephone number ...

20 Enter the following commands to configure the local ports on the East router with the dial-peer information in Table 4: East(config)# dial-peer voice 901 pots East(config-dial-peer)# destination-pattern 19195558282 East(config-dial-peer)# port 1/0 East(config)# dial-peer voice 902 pots East(confi...

22 You can simplify this process by configuring number expansion for East router telephone numbers on the West router: West(config)# num-exp 5.... 1919555.... Now users can dial a five-digit extension beginning with 5 from a telephone on the West router to reach a telephone on the East router. These...

23 Checking the Remote Dial Peer Configuration If you configured VoIP dial peers on your router by following these examples, you can place calls from that router to telephones on the remote routers (using just the extension if you configured number expansion). If you have trouble placing calls, ping...

24 Note In this example, West router voice port 1/0 has two separate POTS dial peers associated with it. Dial peer 201 matches calls beginning with the digit 9 and handles PSTN calls originating from the West router. Dial peer 601 matches calls beginning with the digit 7 and handles calls to the PST...

25 In this example, West users can dial 5 and a four-digit extension to reach telephones in the East office. East users can dial 5 and a four-digit extension to reach telephones in the West office. The West router connects to the PBX through an E&M VIC port 0/0. This port is associated with a PO...

26 Configure the East router similar to the West router. The East router connects to the PBX through an E&M VIC port 0/1. Enter the following commands to configure a POTS dial peer for all East telephones: East(config)# dial-peer voice 211 pots East(config-dial-peer)# destination-pattern 1919555...

27 Figure 22 A Network Using ISDN BRI Voice Interfaces Configuring the BRI Layer 1 At the BRI Layer 1, you can configure each port of the VIC to operate in NT (clock source) or TE (clock slave) mode by using the IOS isdn layer1-emulate command in interface configuration mode: isdn layer1-emulate {ne...

28 where high enables the external clock, and low enables the internal clock to drive the VIC. By default, the clock priority is set to high. Note If the VIC loses its external clock source, as when the ISDN line is down, the internal clock source takes over until the external clock is functioning a...

29 Debugging Commands Use the following commands to debug your configuration: • debug bri • debug isdn q921 • debug isdn q931 • debug isdn events • show isdn status bri • show controller bri • show interfaces bri For more information about these commands, see the IOS documentation. Configuring DID I...

30 Prerequisites The following actions are required to support DID: • Obtain DID service from your service provider. • Establish a working network. • Complete your company’s dial plan. • Establish a working telephony network based on your company’s dial plan. • Install the VIC-2DID cards. For more i...

32 Figure 24 Bandwidth Versus Quality of Service IP Precedence Use the ip precedence command to give voice packets a higher priority than other IP data traffic. Every IP packet is given a precedence level: the numbers 1 through 5 identify classes for IP flows; the numbers 6 through 7 are used for ne...

33 Multilink PPP with Link Fragmentation Interleave Multilink PPP with link fragmentation interleave (MLPPP with LFI) allows large packets to be multilink-encapsulated and fragmented into smaller packets, thus ensuring that voice packets are transmitted without delay; small real-time packets, which ...

34 Note When you enter the show running-config command, the format of the ip rtp header-compression command changes to ip rtp header-compression iphc-format .
