[nsp] wic-1dsu-t1 back to back

[Zed]

Hello,

We are migrating our test environment to our production, and need to do some
testing.  In order to accomplish this, I need to figure out what kind of
cable/pin-outs/extended commands I need for connecting two 2620's with
WIC-1DSU-t1 back to back.

This doc on cisco's site describes the proceedure for a 2524, but even
though I followed the procedure it did not work. Could someone please inform
me as to the correct procedure/cable etc.?
