Does the system you are connecting to have a digital interface (T1) or is it truly a 2/4 Wire E&M system? If it is T-1 then you do not need a channel bank however if it is the analog interface then you will. There are several choices of banks available and there are also several drop and insert muxes that can provide you a smaller number of channels that you can use instead of using all 24 from a channel bank.

You typically do not need a channel bank when using E&M. However, you will probably need a T1 crossover cable, if you are not connecting to the outside world (i.e. cross 1&2 with 4&5). -Tilghman _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
