I have a serious problem right now. My task is to force the MAX-4000 to answer the incoming calls coming from Alcatel System 12 switch. The problem is that we can use only the R2 signaling in E1 trunks between MAX and S-12. Now the MAX can see the trunks. It shows the good state of E1 lines (all dashes in status window, 's' mark for signaling (16th) time slot and 'LA' status). But any call from the external phone/modem cannot be done into the MAX. I've enabled the trace of the activity of the trunks in Alcatel. When I looked at the log I could see the following: when the switch begins sending digits of the called subscriber, the sequence stops for the following reason: after the first digit complete S-12 waits for the MAX to respond with one of the three signals, according to R2 protocol. The first signal is 'A1' which means that MAX requests the calling subscriber category. The second is the signal to query the next digit of the called number. And the third one is to send the 'B6' signal which gives the switch the 'Subscriber is available' state, and therefore the switch can initiate the 'open line' state. BUT MAX DOESN'T RESPOND ANYTHING after the receiving the first digit of the called number! ALcatel waits for the large amount of time (more that 1000ms) and then clears the call and returns the 'inter-station busy' tone to the handset. I've tried the different setups in Alcatel and MAX4000 (and MAX has a few parameters in E1 line profile). Nothing could I change :-(( Has anybody tested the same configuration (MAX4000 and Alcatel System 12 with R2)? Can it work? Please help me, if you can!
