Beginner - Help with routing!


I just started as a network engeneer, and now I already have a problem that I cannot solve... Can anybody help me with the following :

We have 2 cisco routers (1600 series) and we need to switch the 128k leased line tot a 516k leased line ; this does not seem to be very easy for a beginner like me. What do I need to do? (commands?)

When I do sh S0 (after replacing cables), it tells me the line is up, but protocol is down...

Any help is appreciated

Thanks in advance

Re: Beginner - Help with routing!

There should be a setting, if you do SH RUN, on S0 that says something like:

service-module t1 timeslots 1-2 speed 64

Change it to

service-module t1 timeslots 1-8 speed 64

(or whichever channels the telco provisioned for you)

Re: Beginner - Help with routing!

Do a show service-module on your router. For a 128k circuit you should be showing 2 timeslots 1-2.

For a your new circuit you will need to increase the timeslots to 8.

config t

int s0

service-module t1 timeslots 1-8

this will increase your channels to 8. 8x64 being 512K
