I spent some time looking at the the performance monitor on the PRI card. The performance monitor on the 1st DS0 indicated, when i dialed into it, "incoming dialing" and it assigned a quad I modem as the device. There would be several seconds of silence, and then the status would change to "DSO tear down" and I would hear a busy signal. So, it would appear that the call is being routed to the modem, but for some reason the modem is not hearing it and/or not picking up the call. On the HiperArc, the list interfaces shows all the slots/modems as being up/up. The performance monitor indicates that all the DS0's are InService. The PRI card is using fixedassignment and all the DS0's are mapped to a modem. The Line interface is set to "priTdm" and that is the only change I made on the modem card that was working on the CT1. Any ideas would be greatly appreciated.

Hi,
Just went through the same thing...
Spent some time trying to find my mistake, then started poking around the "performance monitor" both on the PRI level and timeslot level. I found that the modems were showing "remote out of service" on all lines. Passed this on to the switch tech, and he did something (switch is a DMS-100) and the lines went to "in service". The whole time my D-channel was up, switch saw it up as well.
Anyhow, looking at the line status in performance monitor in TCM may point you in the right direction...

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.
