Figure 4 Attaching the Cable Guide to the Router PVD M 0 PVD M 1 SLO T 0 SLO T 1 Cable guide screw 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.
Do not connect a WAN, telephone or fax cable to the card until you have completed the installation procedure. Caution Card Installation Follow these steps to insert a card in the router: Make sure the router is turned off and is disconnected from AC power. Step 1 Power must be removed from the system prior to installing or removing WICs or VICs to avoid damaging them.
As an example of voice port numbering, if you install VICs in both slot 1 and slot 2 of the router, the ports in each of these slots would be numbered as follows: Slot 1—1/0 and 1/1 Slot 2—2/0 and 2/1 Figure 7 shows the Cisco 1760 router front panel and slot numbering. Figure 7 Cisco 1760 Router Front Panel PVDM 0...
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 network voltage (TNV) circuits. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information for Cisco 1700 Routers document that came with the router.) Caution...

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 to be grounded. Use a green-and-yellow 14 AWG ground wire to connect the host to earth ground during normal use.
• MOD OK—On when the virtual private network (VPN) module is correctly installed in its slot and is recognized by the system. 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 installation.

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: Command Step 1 Router(config)# interface fastethernet 0/0 Step 2 Router(config-if)# ip address 20.20.20.20 255.255.255.0 Step 3 Router(config-if)# no shutdown...

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 the “Configuring FXS Interfaces”...

Figure 12 shows a basic voice network. A small business uses a Cisco 1760 router (named West) to provide telephone and fax connections among employees in its office. Two of these telephones are connected to an FXS VIC port in the West router.

Table 2 West Router Telephone Numbers and Voice Ports Telephone Number Voice Port 408 555-3737 408 555-4141 If your router is configured with four 2-port VICs, you can connect a total of eight telephones and fax machines to it. Note 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.

Figure 16 IP Connection Between Routers 408 555-3737 FXS VIC 192.168.19.27 West FXS VIC 408 555-4141 Look at the connection between the West router and the IP network. This connection does not include a voice port or an attached telephone—it leads from a WAN interface to a remote destination somewhere on the IP network. IP routers can locate IP addresses on the network, but they cannot locate telephone numbers.
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.
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 the remote router to make sure you have IP connectivity, or use the show dial-peer voice command to verify that the data you configured is correct.
In this example, West router voice port 1/0 has two separate POTS dial peers associated with it. Dial peer 201 matches Note 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 PSTN originating from the East router.

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 POTS dial peer for incoming calls.

(ETSI) Net3 switch type. The BRI VIC presents an ISDN S/T physical interface that connects to a network termination (NT) or terminal equipment (TE) device. With the ISDN BRI VIC, you can connect the Cisco 1760 router to a PBX network in NT or TE mode, or to a PSTN in TE mode.

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 again.

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 are not multilink-encapsulated, are transmitted between fragments of the large packets. The interleaving feature also provides a special transmit queue for the smaller, delay-sensitive packets, enabling them to be transmitted earlier than other flows.
