Background Information

Step Instruction Command Example
1 Set the card to T1 mode card type t1 slot subslot card type t1 0 0
2a Set the clock source to internal (on each DCE port) controller t1 slot/subslot/port
clock source internal
controller t1 0/0/0
clock source internal
2b Set the clock source to line (on each DTE port) controller t1 slot/subslot/port
clock source line
controller t1 0/0/1
clock source line
3 Set the channel group 0 to include all 24 T1 timeslots controller t1 slot/subslot/port
channel-group 0 timeslots 1-24
controller t1 0/0/0
channel-group 0 timeslots 1-24
4 Set the port framing to esf controller t1 slot/subslot/port
framing esf
controller t1 0/0/0
framing esf
5 Set the linecode to b8zs controller t1 slot/subslot/port
linecode b8zs
controller t1 0/0/0
linecode b8zs

You should now have a Serial0/0/0:0 interface and/or Serial0/0/1:0 interface which you can assign an IP address to and use as with any normal serial interface, make sure to include the :0 on the end of the interface though.
