It depends.
What interface does the CSU/DSU have on the Telco (they say "network" side)?
Most CSU/DSUs have an RJ-45/48 jack. Some like Larscom have a DB-15
connector. Yes - you can buy adapters to make it an RJ-45. Not fun to learn

I would check your timing first. If you are getting the T1 from a reliable
telecomm company, use the line's timing. If from somewhere else, set the
timing to internal.

check your service-module t 1 configs. I believe that Cisco defaults to ESF

Did you specify the clock source?

For T-1 CSU/DSU, you're correct it's 1,2 <-> 4,5.

You have to make a T1 crossover cable (Pins 1 and 3 I think, but you should
probably double check) and you will have to configure one of the CSU/DSUs to
provide clocking, usually by setting its clock for internal instead of line.

Use the console cable you get with the routers (at least that's what I use),
and if you use HDLC or PPP on the routers and config the DSU right it will
work like a charm.

Correct me if I am wrong, but he does need a CSU.

Here is what I found from Cisco web site:
http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/cis2600/net_mod2/conntpri.htm#xtocid195789
It says I need a CSU. Any thoughts?

It has been my experience in Europe (where E1 is prevalent) that the PTT (local
telco) provides the CSU. The same thing occurs with the NT1's on ISDN. Only
the US (having gone through divestiture) allows privately owned telco
(CSU/DSU/NT1) equipment.
There are some other issues with Cisco Voice
Sasa,
We've got a 3640 with DB15 E1 connector, E1 line is
Rj45. I thought we should use a CSU, right?
Thanks in advance.

No. For T carrier, you must use DSU/DSU. For E carrier, only
DSU is required, while CSU (or LTU-Line Termination Unit in
E terminology) is not.
So, E1 module that you have includes DSU. DB-15 con
