Hi all I'm trying to configure a TE410P in Europe with three E1s and a T1 channel bank (already bought in the US) to receive and make calls through *. I managed to get the E1s to work, but I'm having trouble with the channel bank (a Rhino). I have tried the bank in spans 1 and 4 changing jumpers in the card (always with no PRI connected, as I have no PRI where I'm testing now, so I'm trying to make the bank work "alone"). I've tried AutoT1 and also configuring it myself, as ESF and D4, with B8ZS and AMI, changing ZAPTEL and ZAPATA. When I plug the channel bank, it goes ok, framing and signalling lighting green, but after a few seconds, signalling starts blinking, alarm lights red, with display saying "Loss of carrier - (LOS - no T1), Asterisk and zttool detecting yellow alarm. The upper right corner of the displays says WINK ESF. Any ideas? Thanks in advance!
