Adding additonal DSU/CSU T1 module on Cisco2600 router

[Springman]

#143199

We have a single private T1 bridging between the Boston office and San Fran office. We are adding another T1 line to expend the bandwidth. I have ordered the DSU/CSU module to put in. I need your help to make the new config working.

Current config for Boston office

=================

I guess after I add the 2nd module in, for interface serial1/0 I can pretty much copy the config from s0/0 over but with a different ip address. Correct me if this is wrong.

Here is the IP addresses for the serial interfaces.
San Fran Boston
192.168.1.1 192.168.1.2
192.168.1.3 192.168.1.4 < --- new My question is more on routing. I don’t know how to modify the route to make the WAN double the capacity. Please help.
