I'm having a bit of trouble getting a channelized T1 circuit to work over a dual T1 card. I know the circuit works okay because I had it up on a DSP card a few minutes ago and have been making test calls for a month no problem. Having eyeballed the settings from card to card and transferring them as best I could, I'm still having a problem. The call appears to go through and sieze a modem but the modem LED turns red and all that is heard is a high pitched tone. I plugged all this into 3KB and came up with problem ID:1.0.29434755.2181891: Please follow these steps: 1. Call telephone company and do two-way tone tests on the Quad Modems with them. Within Total Control Manager, open the menu Fault then select Remote Testing for "Send a Tone" and 'Receive a Tone" 2. Upon tone tests see which path is not generating transponder tones at a particular db level and once identified, telco will fix that path and modems will negotiate calls fine thereafter. Note: Possible sources include NULL ANI/DNIS fields or improper DSO call seizure with missing off-hook condition (E&M Type 2 trunks). However, the same circuit worked fine for a month over a HiPerDSP. It's entirely possible that I'm missing something obvious since I have always used PRI for quads up to this point. Is there something obvious that I'm missing? I'm using (and these options work fine on the DSP): ESF, B8ZS, No Dial In Address, Wink Start, eAndMTypeII trunk, and DTMF tones.
