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.
Note: You need to adjust multiple lines of this configuration for the correct slot numbering on the router you are working on. In particular our 1900 series routers have serial cards in slot 0 subslot 0 and our 4000 series routers have cards in slot 0 subslot 1.
Sample Two Card Configuration
Note: You need to adjust multiple lines of this configuration for the correct slot numbering on the router you are working on. In particular our 1900 series routers have serial cards in s0/0 and our 4000 series routers have cards in s0/1.
