Serial 4A/S vs: WIC 1DSU-T1

                   After searching and reading many documents I still can not confirm the following:

Serial 4A/S vs: WIC 1DSU-T1

What is the difference between these 2 cards, is it just cabling? DCE-DTE vs: RJ-48?

The lab I'm doing (Split-Horizon) calls for 3 routers w/ 1 serial port and 1 router with 3 serial port. Not sure what serial port network module the lab book is referring too, or if it matters. I'm assuming its referring to the Serial 4A/S due to the cable requirements being DCE/DTE backto back cables.

Can I use in the router needing 3 seial ports, 2 off of the Serial 4A/S and 1 off of the WIC DSU-T1 card to create this frme-relay network?

Thanks

Jeff

If you're talking about dce/dte cables, that's definitely the a/s card. The dsu is there to provide signaling, timing and line coding when you connect up to a provider network.

You could cross-connect two routers with dsu cards by using a cross t-1 cable. Google for the pinouts.
