Phil, It sounds like your carrier is just using a channel bank to split off six of your E1 channels into analog FXO ports. You will want this for fax lines, security systems, and dialup connections since doing this over VoIP/Asterisk can be problematic. It is best to keep these lines out of the PBX. I have done several implementations on IBM x305 and x306 servers and they work great. I cannot comment on the x100 though, since I have no experience with it.

We use the analog lines but what is confusing is there's no mention of these analog lines in any documentation or on the bill. The problem I have is I need to supply similar in our new premesis and need to understand how it works. I'm looking to replace our current telephone system with Asterisk. I'll deal with the configuration later :-) Also, I'm looking at an IBM xSeries x100 server for Asterisk to run on. It has a 3 gig processor and I was wondering if this would be ok to handle about 8 consecutive calls. The card I'm looking at is the Wildcard TE110P. Has anyone had any echo problems with this card? Would this setup work? Hope all this makes sense! Thank you in advance Phil.
