A channel bank is a device used to aggregate (or break apart) individual FXS and FXO ports to/from a T1 connection. Basically, channel banks save time, energy, space and wiring mess. They also often give higher FXO/FXS interface quality as well. They cost a little more but IMO if you take everything into account they are by far cheaper in the long run. Anyway as mentioned channel banks are an easy/cheaper way to aggregate lines. Instead of having 24 Sipura boxes or 6 TDM400P cards and all the wiring mess that goes with it, you have a single T1 card and a single cable going to a single channel bank, which will have a single D50 connector that you can terminate directly to a single BIX punchdown strip. Channel banks are also typically (much) higher quality than the cards or low-density ATAs you can buy. I am particuarly fond of Carrier Access Adit600s. -A. _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
