Hi all, I am not a new user of asterisk. I have been working on sip only configuration for about 2 years. Now im planning to explore and see how to use E1 lines with asterisk. I have read the ATFOT but it talks about the TDM cards. I want to install E1 card on asterisk. How do i install and configure it. Right now im planning to buy a 2 port E1 card. Can anybody help me out on this and show me the right direction? I have adequate knowledge of E1 lines (32 lines coming in on a single wire). How do we separate each line out in asterisk? What kind of machine do i need to process 32 calls (or 64 calls incase i buy a 2 port E1 card). -- Best Regards Rizwan Hisham -------------- next part -------------- An HTML attachment was scrubbed...

Can anybody > help me out on this and show me the right direction?Generally, only 30 channels of that E1 are usable for voice. One of the channels is devoted to timing and another one of the channels is generally used for signalling. The channels are usually signalled thusly: zaptel.conf (upcoming as /etc/dahdi.conf) bchan=1-15,17-31,33-48,50-62 dchan=16,47 and: zapata.conf (upcoming as /etc/asterisk/chan_dahdi.conf) pri_cpe=1-15,17-31,33-48,50-62 The channels are accessible in Asterisk as Zap/1, Zap/2, etc. up to Zap/62. Note that you MUST keep the gaps for the D channels.> I have adequate knowledge of E1 lines (32 lines coming in on a single > wire).

Single core, 1.2GHz should handle it fine, and any extra hardware you throw at it will be gravy. -- Tilghman

Thanx a lot Tzafrir and Tlighman. But i need to clear some more concepts before starting to implement anything. In ATFOT i read about configuring an analogue pstn line, by configuring /etc/zaptel.conf and some other things in etc/asterisk/zapata.conf, that was just one line. if I configure the E1 card then ,correct me if im wrong, i will have similar 32 channels like that single pstn line in TDM card, The only difference will be the number of channels? what are b & d channels and whats the difference between them? Talighman.. Can a 1.2GH machine handle 62 CONCURRENT zap calls? If you can provide me a good source where i can find all the necessary info then it will be more easier and faster for me.

I was giving you an example generated by genzaptelconf for a T1, I am assuming that if you set the jumpers on the board to E1 or it is an E1 card, genzaptelconf will create the appropriate settings. I know the Sangoma scripts do. If you have issues with your setup, sometimes crc4 can cause issues. The LED on the card flashes from greed to red quickly was the symptom I found. Thanks, Steve Totaro
