UK WAN module

[rcalhoun]

We are going to be installing a link to an office in the United Kingdom. We are new to that part of the world and are unsure if they use the T1 standard or the E1 standard. If they use the E1 standard, what type of module do I need to use in a 2621 series router? Do the E1 modules have a built in DSU? And what are the settings for E1? Any help on this would be great. The connection is strictly a data connection. No voice on it.

In the UK it is normal for the carrier to supply a CSU/DSU & it remains their property.

You want a WIC-1T or WIC-2T for the router, and the appropriate X.21 DTE cable most likely, though check with the carrier - 3 out of the several hundred UK E1's I've seen were presented as G.703 twin 75 ohm. X.21 is the norm.
