Hi,
This is a sample configuration for your information.
card type t1
controller T1 0
framing esf
linecode b8zs
tdm-group 2 timeslots 13-24
!
controller T1 1
framing esf
clock source internal
linecode b8zs
tdm-group 3 timeslots 1-12
!
connect dfw1 T1 0 2 T1 1 3
The following shows a configuration for the Cisco 2651 router in Figure 2:
controller T1 0/0
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 13-24
!
interface Serial 0/0:0
ip address 209.165.200.253 255.255.255.224
The following shows a configuration for the Cisco 3640 router in Figure 2:
controller T1 0/0
framing esf
linecode b8zs
channel-group 2 timeslots 1-12
!
interface Serial 0/0:0
ip address 209.165.200.252 255.255.255.224
Please note the following:
?The tdm-group 2 timeslots 13-24 command defines drop-and-insert capability by setting the time slots from each T1 that will be used in the digital cross-connection.
?The connect dfw1 T1 0 2 T1 1 3 command activates the drop-and-insert digital cross-connection between the T1s. The dfw1 parameter is a name for the cross-connection; the name can be any word, any number, or any series of letters.
?You can verify drop-and-insert connections by using the show connection all command.
Verifying Controller Settings
The show controller t1/e1 command displays the status of T1 or E1 controllers and displays information about clock sources for the ports:
Router#show controller t1
T1 0 is up.
Applique type is Channelized T1
Cablelength is long gain36 0db
No alarms detected.
alarm-trigger is not set
Version info Firmware: 20011109, FPGA: 15
Framing is ESF, Line Code is B8ZS, Clock Source is Line.
Data in current interval (708 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
