[Asterisk-Users] Hardwiring a Tellabs echo canceller - help req
Hi All, Greg has been a huge help getting me going with this tellabs echo can, but I'm still having some problems getting it to work... I suspect I wired it up incorrectly, so I thought I'd see if anyone can point me in the right direction. Digium tech support pointed me to this doc for a standard T1 cable: http://www.arcelect.com/RJ48C_and_RJ48S_8_position_jack_.htm which looks like it means: pin1 = recieve ring pin2 = recive tip pin4 = send ring pin5 = send tip So I treated the bottom part of the diagram like a noraml cat5 cable & connected it in this way: Zap side | 2572 side -------------------- pin 1 <=> pin 25 pin 2 <=> pin 21 pin 4 <=> pin 10 pin 5 <=> pin 6 on the T1 side I have: T1 side | 2572 side --------------------- pin1 <=> 26 pin2 <=> 22 pin4 <=> 9 pin5 <=> 5 In the wiki page for these pinouts are listed as T1 side(drop) 5 Send In Tip 9 Send In Ring 22 Receive Out Tip 26 Receive Out Ring Zap side (line) 21 Receive In Tip 25 Receive In Ring 6 Send Out Tip 10 Send Out Ring and I'm not sure what the 'in' & 'out' desinations mean.... can anyone help me or point me in the right direction for wiring this bugger up? perhaps I did do it correctly & the can isn't configured yet (just did that, but can't test till 2night when the office clears out) Thanks in advance for any insights Dan

Dan, Basically you go send tip > send tip, receive tip > receive tip and so forth on both connectors. I needed to use one cat 5 out of the ec to the channel bank, and one crossover t1 cable to the zaptel card. Receive in means receive basically (because it's the incoming signal). You should be able to loop the card to see if it's working, either with a straighthrough or a crossover, I don't recall.... If it loops you'll get AIS Loop on the card (you'll notice it) Greg -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Dan Elder Sent: Friday, January 20, 2006 3:14 PM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] Hardwiring a Tellabs echo canceller - help req Hi All, Greg has been a huge help getting me going with this tellabs echo can, but I'm still having some problems getting it to work...
