Hi, Can anybody with previous experience with it guide me on how to setup asterisk with analog e&m to connect it to an old style e&m system which uses 4 pair cables on RJ 45 jacks. All the analog cards I know of use RJ 11 jacks. And there is no choice of modernization of the customer equipment. Cable pin out are as follows: 1. M lead 2. E lead 3. Tip1 4. Ring 5. Tip 6. Ring1 7. SG 8. SB Zeeshan A Zakaria -- Sent from my Android phone with K-9 Mail. -------------- next part -------------- An HTML attachment was scrubbed...

The only way to provide analog E&M support from Asterisk over DAHDI is to connect a port on a T-1 card to a channel bank with E&M cards in it. These should be pretty easy to find on the used market. -- Kevin P.

Thanks Kevin for your reply. We tried this option with two MultiVoIP devices but results were not satisfactory. I was hoping I could do it without any external device. My team doesn't want to take any more third party-asterisk integration risk for this mission critical communication system after bad MultiVoIP experience. I know there is an Adtran device which does it all in one box, and we have it deployed at some sites and they work flawlessly, but they are expensive too.

Thank you for this info. I'll look into this equipment and other similar. Zeeshan A Zakaria -- Sent from my Android phone with K-9 Mail. On 2010-04-22 6:27 PM, "Kevin P.

Look for a Carrier Access ADIT 600 or something similar; pretty much any modular T1 channel bank should have E&M cards available. E&M will be expensive (somewhat) no matter which route you take, because it's not something that was deployed in massive volumes like FXS/FXO are, and it was primarily used for trunking between large expensive PBXes. -- Kevin P.
