We use 2800 series routers and WIC-T1DSU/CSU to terminate multiple t1s with MLPPP in the US and Canada. Now I am looking at 3 E1s in the UK (London). I found several very old posts on this. The newest one directly talking about how to terminate an E1 was from 2007. They talked about the VWIC-1MFT-E1 which (and 2MFT). Is that what I need for 3 E1s in a 2821? What kind of CSUs are available/recommendad for E1s? Am I wrong to assume I can still use MLPPP?
