2620 Point to Point T1 Requirements

[techshoot]

I have a pair of 2620 Routers that had been used as frame relay/T1 connections between two locations. We are now installing a Point to Point connection between the two with a new vendor. I am at a loss on Cisco configurations, though have managed to squeak by a few issues so far. One unit has a T1 DSU/CSU module installed along with 56K DSU/CSU modules and one has a T1 Drop&Insert (2 port) daughter card and a 56K DSU/CSU and a High Density Voice port adapter, 0 ports installed. Are these sufficient for this configuration or is there something in addition that I need. There used to be another frame relay connection to the one with the drop&Insert card which is gone and it handled an 800 line across the T1 which is also gone.

so your going from a frame to a point to point. No problem that I see because you have a T1 wic on say router A and a drop insert im guessing a external csu/dsu V.35 connection if this is so than you are ok. Encapsulation HDLC rather than PPP lets insert a config here to give you an idea

You can setup a Route 0.0.0.0 0.0.0.0 next hop (ser int)

I hope this helps !!!

The router B configuration went pretty much fine for the router with the T1 DSU/CSU card in it, but the configuration for router A with the Channelized T1 would not accept very much at all.

Router B would not accept any ipx paraqmeters at all but the rest went in fine.

Router A configuration has "controller T1 0/1" and "controller T1 0/2" parameters to configure and the 56K DSU/CSU has been "serial 0/0" and "serial 0/1" and I cannot get a "serial1" or "serial2" entry to input. Below is the previous configuration from the frame relay.

See if this works for you on your ipx problem, or
if it's a serial interface you will use hdlc by
default.

 

[techshoot]

Is the ipx actually needed for my configuration since I don't have Novell?

The sample was for a working router that was running IPX, if your not using ipx do not add the statment Jeter@LasVegas.com

Maybe I misunderstood you.
You did say that you were entering ipx commands..
You don't need ipx for an ip only config...

I made that comment and figured that much at the start but was asking for confirming. I tried a different configuration on the Channelized T1 router and it looked like it was going to work but had a problem with the one with the T1 DSU/CSU saying the serial was down and the line protocol was down indicating no CD. It was past business hours there so I couldn't have anyone check the cabling. Since the router works with the other line (which is still up until we get the new one working) it isn't a hardware problem.
