The final straw.....
I had followed some guidance in an article and wired up a double female jack as a T1 cross-over. I had also tried a couple of different combinations based on seeing confusing recommendations about some systems reversing T/R polarity for certain cross-overs. Had my usual...
I read the last post, followed the link, and wanted to scream!
As many times as I've been on the voip-info site and various forums and articles I'd never stumbled on that one that made the process seem cut and dried. So I tried it... and still have an ailing D channel...
One thing I am a little...
Finally got a chance to get back in the closet with my Magix chassis and Asterisk box. I maybe should repeat the Magix, maybe there are significant differences between Magix and Legend. It seems that there are 3 layers to the system setup; DS1, PRI and then B-channel group.
My DS1 settings are...
Thanks, I'll check that.
Can easily wait till Tuesday, been working on this on and off for almost 3 months now so a few more days won't hurt.
Good Luck!

Hi Telecomboy
Tried your suggestion for NI1-custom today and Asterisk wouldn't start. I haven't been able to find that option documented anywhere, can you point me to a source? But; with the channels manually defined, direct cross-over cabling and switchtype at ni1 we at least went from a...
My apologies for turning this discussion totally Asterisk and I'd be happy to take it off-line if requested but could I get one more clarification? The option for NI1 Custom is in zapata.conf, correct? The Asterisk config file?
We had thought that the card and Zaptel config needed to be able to...
WOW!
Some very good feedback.
I've spent some time on Avaya's site, read the feature and programmer's reference but not the network manual, will get a copy.
Then I also need to find some quality closet time to see if using NI1 works in my situation.
Thanks All!
I'll be sure to post my...
Thanks for that
Yes, it took quite a while to come to the conclusion that wiring was a likely culprit and make a proper cross-over connector. I found a post somewhere where the person used a double female jack to make a crossover coupler and that is what finally got me a solid connection between...
Yes, one of the first things we tried was to loop-back the Digium card. Now, with the CSU in place I also did loop-back testing from it (but now that I think about it, I only did the loop-back towards Asterisk, not to Magix); next attempt, thanks.
Just found this thread today and it comes close...
Kwing: I've tried every possible combination of cable (straight, T1 cross- normal polarity and T1 cross-reverse polarity) and always had the same red alarm on the Digium T1 card. Some say that's an indication of a wiring error. The connection between the Digium card and CSU is solid now but I...
Project Update:
After searching many forums and talking to a few systems integrators it seemed that a CSU would be necessary to successfully connect an Asterisk T1 to my Magix 100 DS1 port. I now have an Adtran TSU 120 connected between the systems and a solid link between the Adtran and...
G' morning Tim
I didn't take your reply to mean you were dissing the system, just that it had limitations, don't they all.
I was able to dig up an old cut sheet that I'm pretty sure still applies to this T.
D channel: N/A
B channels: 6242-2544 thru 3725
Configuration:
Channels
Frame: ESF

Thanks Tim and Jim
Hope it's appropriate in this forum to respond to both in one reply.
I'm much more of an ethernet guy and hope any analogies I make are understood. I'm starting to gain a limited understanding that the 24 DS0s in a DS1 can be used to carry much more diverse traffic than I had...
This has probably been answered many times before but not where I've been able to find.
I've read too many articles on T1 specs but none of them seem to mention loop vs ground start signaling. All that I have seen seems to indicate that only applies to analog lines.
I'm asking because during a...
Hope someone here can point me in the right direction.
As several others have mentioned I'm also a PBX newbie, more of a networking / data guy that ended up "owning" the phone system too.
I have 3 older Avaya systems; 2 are Magix R2 and 1 is a Legend (not sure of the revision off hand) These are...
