WIC-1DSU-T1 Crossover Config


This post is in the category: Configurations

Posts here will mostly contain full configuration files for my own reference and will not likely not have much explanation. See posts in the Guides category for more explanational posts.


T1 cards can be used to make direct connections for lab purposes.

Like a standard serial interface, one will have to provide the clocking. The configuration would look something like this.

interface Serial0/2
 ip address 10.0.0.1 255.255.255.252
 encapsulation ppp
 service-module t1 clock source internal
 service-module t1 timeslots 1-24
 no peer neighbor-route
 no shutdown

For the side of the connection without clocking, omit this line:

service-module t1 clock source internal

You will likely need to make a cable to connect the two cards. This is not a standard crossover. It needs to have the below mapping.
