Here is my set-up:
2 2600 Cisco routers. Both have an available Smart Serial port.
WAN connection via a 56k circuit over X.25 on a 1T WIC w/ separate CSU
We will be upgrading the circuit to T1. Telco has installed the T1 and loop back from CSU to CSU is good.
I was wondering if we could go ahead and add the T1 to an available Smart Serial port on the 2T WIC. On Cisco’s website it looks like it will support that speed. I would like to add the T1 while the 56k is still running so that the planned cut-over goes smooth. Is there any downside of this? Besides setting the Bandwidth to 1544 and Encapsulation to PPP on both routers are there any other settings I need on the routers?
