Just for the record, this is generally a correct statement. I can't speak for every T1 interface out there, but every T1 interface I've personally used does respond to the so-called "hard loopback" that is described elsewhere in this thread. The hard loopback really is just a layer one test. On Zaptel you should definitely see a green light when you plug in a loopback test plug. This is kind of a sanity test - not necessarily for the equipment but rather for the guy trying to make it run! :) It is a very basic test, and it fits in with "is the computer plugged in and turned" and "did the zaptel driver(s) get loaded" and such. A green light simply means that the layer one connection is working - the physical connection, the framing and coding, timing, etc. Obviously this needs to be working before you can get meaningful traffic moving over the interface... Happy T1/E1-ing. -MC _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
