Chapter 6 Configuring the 8-Port and 16-Port FXS RJ-21 Modules
Sample Configuration
Using the configuration template above, you could configure the Cisco 2600 as follows:
[Configure the fast ethernet interface]
2600# conf t
Enter configuration commands, one per line. End with CNTL/Z.
2600(config)# interface FastEthernet0/0
2600(config-if)# ip address 172.20.59.61 255.255.255.0
[Configure the POTS call leg, as shown in the template above]
2600(config-if)# dial-peer voice 1 pots
2600(config-dial-peer)# destination-pattern 10
2600(config-dial-peer)# port 1/1/0
[Configure the VOIP call leg, as shown in the template above]
2600(config-dial-peer)# dial-peer voice 2 voip
2600(config-dial-peer)# destination-pattern 20
2600(config-dial-peer)# session target ipv4:172.20.59.93
Similarly, the 8-Port RJ-21 FXS module could be configured as follows:
[Configure the fast ethernet interface]
gateway# conf t
Enter configuration commands, one per line. End with CNTL/Z.
gateway(config)# interface FastEthernet5/0
gateway(config-if)# ip address 172.20.59.93 255.255.0.0
[Configure the POTS call leg as shown in the template above]
gateway(config-if)# dial-peer voice 1 pots
gateway(config-dial-peer)# destination-pattern 20
gateway(config-dial-peer)# port 4/0
[Configure the VOIP call leg, as shown in the template above]
gateway(config-dial-peer)# dial-peer voice 2 voip
gateway(config-dial-peer)# destination-pattern 10
gateway(config-dial-peer)# session target ipv4:172.20.59.61
At this point, you should be able to send a fax or phone call from the Cisco 2600 to the FXS module,
and vice versa.

1. Assigns a unique number (1, 2,...) to a dial peer. Has only local significance.
2. Assigns phone numbers to dial peers. The router directs voice calls based on these patterns.
3. Identifies the remote end of the VoIP call, which can be specified using an IP address (as shown in the configuration) or a
DNS name.
