Hello, I want to link several * boxes together. Some of them are dedicated as "user" servers (SIP and IAX clients connect to them) and some are used as PRI servers (where the PRIs are hooked onto). I think TDMoE is the only channel type where you can group different Interfaces into a single group. E.g. for using Dial(ZAP/g1/12345), I think you cannot group different IAX accounts and use them via Dial(IAX/g1/12345). Or am I wrong?? So I looked at the WIKI and it shows an example using "em" signalling. What other signallings are supported by TDMoE? How many TDMoE trunks with 30 channels each may I run on a 100 Mbit/s LAN dedicated to TDMoe??? Regards, Marc
Hi, Unless you have a very large configuration, the bandwidth of a 100Mbps ethernet will not be the issue. Theoretically you could have 10 E1's worth of TDMoE traffic on a single 100Mbps wire. I have sucessfully used EuroISDN with one 31 channel TDMoE (E1 is 32 64Kbps channels, where one is used for framming, so you have 31 useable channels). You could use Trunked IAX2 as well, the advantage is to avoid cross-coding, as TDMoE can only use uLaw/aLaw, while trunked IAX2 can use any useable Asterisk codec. However TDMoE to PRI/FXS/FXO connections are more efficient, as they can use zaptel bridging.

Or am I wrong??IAX with groups doesn't make sense. IAX being a network protocol is not physical port limited like PSTN hardware. Your trick here is to understand that you can dial via IAX from one machine to another and the second machine then takes the incoming call and does it's own Dial(Zap/g1/12345). Or with the use of a switch command, the IAX connections to the other side is implied and the remote side says it can complete the call so the "user" machine says, okay, do it. TDMoE has a limitation of X channels per link, and some people have noted troubles when trying to use more than one TDMoE circuit. IAX has no trouble talking to mulitple places and multiple calls. -- Steven Critchfield <critch@basesys.com>
