Cisco Cisco IOS Software Release 12.2(11)YV

The following sections list the new software features supported by the Cisco 1700 series routers for 
Release 12.2(11)YV2.

The following sections describe the new software features supported by the Cisco 1700 series routers for 
Release 12.2(11)YV.

The channel bank feature provides support for the time-division multiplexing (TDM) cross-connect 
functionality on the Cisco 1760 router between analog voice ports and digital DS0s. This feature will 
provide support for 2 to 6 ports cross connected to a T1 channel associated signal (CAS) using a 2-port 
Voice Interface Card (VIC), and a maximum of 12 ports using a 4-port VIC.

To establish a channel bank connection between an analog voice port and a T1 DS0, configure the 
connect command in the global configuration mode. To verify the channel bank connection, use show 
connection all command.

connect connection name voice-port analog voice port T1 T1 endpoint

no connect connection name [voice-port analog voice port T1 T1 endpoint]

connection name ::= name string

analog voice port ::= slot number of port/port number of port

T1 endpoint ::= slot number of controller/port number of controller DS0-group number

The DS0 group must contain only one time slot. The signaling type of the DS0 group must match that 
of the analog voice port.

The channel bank feature is not supported on the Cisco 1751 router.

In the following example, E&M port 2/1 is configured for a Channel Bank connection with timeslot 1 
on T1 1/0.

(config)#controller T1 1/0

(config-controller)#ds0-group 1 timeslot 1 type e&m-wink

(config-controller)#exit

(config)#voice-port 2/1

(config-voiceport)#operation 4-wire

(config-voiceport)#type 2

(config-voiceport)#signal wink

(config-voiceport)#exit

(config)#connect connect2 voice-port 2/1 T1 1/0 1
