Never configured a Paradyne CSU, but if it is anything like the Adtran

Most CSU/DSUs have an RJ-45/48 jack. Some like Larscom have a DB-15

manualy connecting from a switch or router
First thoughts are that if I needed to connect to a CSU that I'd connect to
its console port. To do that I'd do reverse telnet using the aux port of the
router. Biggest issue would be verifying the pin outs. Might have to build a
custom cable or adapter. HTH

Rest of the lab consists of:
2503, 2504, 2509, 2513, and a 4000 as the frame relay switch.
Thanks a bunch for any suggestions or information
Working on an old 2524 w/T1 CSU/DSU on S0. This CSU/DSU is very different
that that for the 2600.
I am having trouble following the instruction at this URL

Can anyone share some experience ?
Thanks

layer protocol. In
addition, each serial link is entirely separate from the others and
can
have differing clockrates.
Be sure that you set your clockrate on the DCE side only. The DTE
side
does not need to be specified because it is, by definition, listening
to
the clock from the DCE.
There are two different issues here that people tend to get confused
about. Remember the OSI 7-layer model, particularly the lower two layers?
OK. Physical layer. The clocking on the wire is a physical-layer
function. If you have a back-to-back cable between 2 routers (no csu/dsu),
then one
Hi folks,
I am wondering how do you out together CSU/DSU, DTE/DCE and a router =
into a neat physical arrangement. I am familiar with each one of them =
look wise. But that's it. Could someone come forward to explain=20

Subha,
Well a typical configuration looks somehting like this
1. how the physical arrangement is done in a most basic WAN connection?
A1. ( WAN CLOUD )=CSU/DSU--Router
2. What role does CSU/DSU play? What is the role of DTE/DCE.

2. What role does CSU/DSU play? What is the role of DTE/DCE.
A2. The CSU is a device that performs protective and diagnostic functions
for a telecommunications line. The DSU is a device that connects
a terminal
to a digital line. Typically, the two devices are packaged as a
single unit

If I connect my routers via serial interfaces using a crossover serial cable
, do I need to set a clock rate even if I'm running fame relay? If I do need
to use a clock rate do all the routers need to be set for the same clock
rate?
Thanks

What are the disadvantages of setting up a lab with 4 or 5 routers all
connected via Serial interfaces without using CSU/DSUs?
Thanks!

All,
Does anyone know if I can connect my 2-2524's via their 4-wire 56K
CSU/DSU's? I know I can connect them via the 5-in-1 modules with a DB60
back-to-back cable, but I don't know if a 56K will connect to another 56K
module.
Thanks,
Bob

Thanks Jack. Do you know, or does anyone for that matter, for sure that
this works? I
currently only have 1 56K CSU/DSU module and would like to purchase
another, though
I want to be sure it works prior to purchasing.
Thanks again,
Bob
