Hi Michelle, You should be able to use the G.703 interface on the 3Com NETBuilder, but you need to find out if it supports the signaling that Morocan Telecom provide.... The other modules, like Kentrox usually have X.21 on the rear, so you would need to have a router with an X.21 Interface... Does the 3Com stuff really work?
A Kentrox DataSMART 456 should do the trick if you need x.21 on the other end... The DigitalLink (now quickeagle) also work ok. http://www.quickeagle.com/solutions/soloe1dsu.asp As for using the G.703 card on the 3Com... You are very reliant on 3com to provide you with BUG free software, that it doesnt keep dropping the line
