Okay here is the set up.
I have a PM-3, with 2 CT-1's feeding it. Running 3.5.1b8. Our company is both
the ISP and a local rural telco.
I am going to be supplying service to a telephone exchange several hundred
miles from
here. The phone calls from that exchange are forwarded across our fiber optic
telephone network to our main CO/modem location.
If I call the PM-3 from my main telephone exchange where the PMs are located:
works great.
If I call the PM-3 from the remote telephone exchange:
works great.
If I make a long distance call from my main location to the telephone number
at the remote exchange: the call goes through, but the modems fail to train.
The failed phone calls leave my main phone switch, go across the US West
toll network, hit my remote exchange and then get forwarded back to my PM-3s.
Some of the phone goes say it is the cumulative propagation delays that are
causing the failure. I disagree. I think it is some conditioning in the phone
network that is causing the problem.
I would appreciate any input from users who have more telephone network
knowledge or experience in similiar situations. I will probably open a ticket
with livingston today, but thought I would start here.
Thanks,
