We have several TC chassis with quad modems that we want to convert to PRI.
One of chassis has a DSP (2.1.9) card that works fine with a PRI. They all
have HyperArc with 5.0.99 software.
The process I went through on a chassis was to load the current PRI software
on the T1/PRI card, and set the trunk setting b8zs,esf, switch type 5ess,
(although I believe they have a CTI switch). The other settings match
(dnis,eandmtypeII, wink, etc) the CT1 settings. Then on the Quad modems I
set the "Line Interface Source" from t1Tdm to priTdm. Save and reboot.
When everything is connected, I have all green lights, and the switch guy
sees the d channel come up. When we dial into that line, the switch guy
sees the call come in on the first trunk but the modem doesn't answer. I
don't see any lights flash on the modem card to indicate a call coming in.
The default config on the PRI card is round robin allocation of modems as
opposed to fixed assignment which I didn't change. The DSP card is using
fixed assignment routing.
If the switch guy converts it back to a CT1, and I load the CT1 software
back in, and switch the line interface source on the quad cards, then it
works fine.
Can anyone tell me what I am missing, or point me in a direction to look?
Thanks.
