3640 WAN Simulation

[cpc]

I have 2 cisco 3640 routers which each have a (WIC 1 DSU/CSU T1) module installed in them. First, can I connect the ports back to back with a cross-over cable without causing any damage to the modules, due to transmit power levels ? Finally, What would the pin out be for a cross-over cable of this type?

Thanks in Advance

Look at the serial port FAQ here in the forum. It has the details you need for this

Yes,

You can hook up both routers back to back (I have done it to confirm my hardware is working).

You need to make a "T1" x-over cable... To find out how to make this, just go to:

http://www.google.com

and do a search for T1 x-over.

Good luck!

From memory, the last one I made was:

1 - 4
2 - 5

For a T1 x-over.....

1 - 5
2 - 4
4 - 2
5 - 1

You need to cross both pairs RX and TX
