Need help configure Cisco routers for private leased line

I have a Cisco 2611 and a 1711 routers. We're currently using the 2 routers to do frame relay (512K). I'll be switching it over to a full T1 leased line next month. I have never configure the routers for this type of connection before. Would appreciate any helps I can get to configure them. Thanks in advance to everyone.

Re: Need help configure Cisco routers for private leased line

are you installing wic-1dsu-t1 cards or using external CSUs?

It would be with internal CSU/DSL on both routers.

Normally on point to point connections it is a dry circuit. On one of your routers, you must provide clocking. On the other end, you will take clocking from the line. You'd end up with something like this:

Router1 (provides clocking)

Interface serial 0/0

service-module t1 clock source internal

service-module t1 timeslots 1-24 speed 64

service-module t1 framing esf

service-module t1 linecode b8zs

ip address 10.1.1.1 255.255.255.0

encapsulation ppp

Router2:

Interface serial 0/0

service-module t1 clock source line

service-module t1 timeslots 1-24 speed 64

service-module t1 framing esf

service-module t1 linecode b8zs

ip address 10.1.1.2 255.255.255.0

encapsulation ppp

Re: Need help configure Cisco routers for private leased line

Thank you so much. I'll give this a try and let you know. So beside this configuration, there's nothing else that I need to type? Thanks again.

That was just an example. There may be some things you have to change:

Your DSU may be in a different slot than s0/0.

Change the IPs to what you want.

Make sure you have routing (either via static routes or dynamic routing) working ok.

-HTH
