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.
