Example 4: 4 Channels of Robbed-Bit signaling to a T1 Interface
This example connects four channels from T1 0/2 to four channels on T1 1/1. They will be robbed-bit
signaling. The NetVanta 950 is loop timed from T1 0/1. The settings in this example are common, and
most of the settings are the default settings.

Enter configuration mode for T1 interface 0/2
4
IAD (config-t1 0/2)# tdm-group 2
timeslots 13-16
Create a TDM group of timeslots 13 through 16
on T1 0/2
5
IAD (config-t1 0/2)# no shutdown
Activate T1 0/2
6
IAD (config-t1 0/2)# exit
Exit to Global configuration mode
7
IAD (config)# interface t1 1/1
Enter configuration mode for T1 interface 1/1
8
IAD (config-t1 1/1)# tdm-group 1
timeslots 1-4
Create a TDM group of timeslots 1 through 4 on
T1 1/1
9
IAD (config-t1 1/1)# no shutdown
Activate T1 1/1
10
IAD (config-t1 1/1)# exit
Exit to Global configuration mode
11
IAD (config)# clock source t1 0/1
Set the system clock source to T1 interface 0/1
12
IAD (config)# cross-connect 37 t1 0/2 2
t1 1/1 1 rbs
Create a connection between T1 0/2 TDM group
2 and T1 1/1 TDM group 1 and preserves
robbed-bit signaling
13
IAD (config)# exit
Exit Global configuration mode
This configuration must be saved to maintain settings after a unit reboot. Type
copy
running-config startup-config
to save the running configuration to the start-up
configuration.
The same script may be used for four channels of clear channel instead of robbed-bit
signaling by omitting the
rbs
flag on the cross-connect command.
