Re: (usr-tc) Quad ana/dig modem not taking calls (another case of)
Hi Dan , Am I correct in thinking from your original mail both Analog and Digital were failing, from your Debug you attached in you second mail Analog call connect. What I see from the Debug is a follows Working Analog calls Failed Digital Call Telco Nas Telco Nas I -3 -> I -3 -> A-1 <- A1 ( 5seconds) 0 A1 A-3 3 A1 3 A1 -----> Clear Fwd 3 A1 I-3 A3 ii-1 B6 <- Answer The problem is when a Digital calls comes form your telco, we get the first digit and we respond to it with a A-1, The telco should then should send the next digit but the NAS times out ( normal condition) as no other digits or recieved, the NAS then sends a digit complete , but the telco send a clear forward . Two issues to look into either telco not seeing our A-1 or there is a problem with the telco digital call service. Talk to your telco make sure you service can have a digital service.

You can call me stupid. Yes the e1/cas got the first digit, sent the A-1, but the telco didn't recognize the A-1 so it never sent the other digits. The problem: the e1/cas had the 'companding' setting on 'use modem country code'. Well, the digital modems are for europe (A-law) and the analog/digitals are for US (u-law). I wonder how an A-law encoded signal sounds after decoded with u-law. And viceversa. The 'companding' is set to A-law now, and all the modems are taking calls. Now an unrelated question: the e1/cas shows 'project id' as a=R2 q=Q412, but I can set only one value for 'project id'. As a result, each time I reset the e1/cas card, I have to do it twice, because after first reset the a= and c= values are incorrect (both Q421 or R2), and after the seconde reset it takes about 30s to detect the correct values and start taking calls. Is there anything that can be done?
