T1 Link with VWIC-2MFT-T1

First insert the new VWIC card when router is power off.
fix screws tightly
Connect the T1 cable which is from the ISP side to the controller you want to configure
power up the router

log in to router using prefer method (telnet / console/etc)

configure controller as follow


MPLS(config)#controller T1 0/0
MPLS(config-controller)# framing esf
MPLS(config-controller)# linecode b8zs
 MPLS(config-controller)#channel-group 0 timeslots 1-24 speed 64

In here you have to calculate/inquire the speed before you configure the speed under channel-group.

calculate is simple as follows
 speed = bandwidth / number of channels

if you configure controller then issue a sh run and see the virtual serial is appeared or not. if not you did not configure it correctly or your controller is not active

ex:
interface Serial0/0:0

then you can configure the serial interface according to ISP given settings

after that you can issue sh ip interface brief command and see the interface and line protocol is up or not.
If you configure wrong speed under channel-group line won't  come up...
