service-module t1 linecode b8zs
My question is that cisco website says there are two type of cable connections for this type of config --
which are --
Set one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.
For my network connection which type of config i should use??
Secondly i try to connect these ports by normal crossover cable it did not work.
So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.
I check cable from ebay which is
RJ45 RJ48 cross over -- will this cable work in my router to router connection.
Thanks

Mahesh,
Yes, this would work too. If you are close to an electronic store, you can usually pick them up at the store, but ebay is cheaper. Get 2 or 3 6 FT cables.
What part of Canada you live in?
Thanks,
Reza

Hi Mahesh,
All you need is a T1 Cross over cable. Your modules are T1 with build in CSU/DSU. Don't worry about the 56k CSU/DSU configuration.
You can make your own or buy one.
Here is one:
