Hi, I was told the Carrier Access Adit 600 supports ethernet based channel bank right out of the box. But I cannot confirm whether this is true as nobody seems to use the Adit 600 this way.

No wrangling with > zaptel, etc. IAX as the * <-> Channel bank protocol.Yes. Search the list :-) My idea was close, but a little different. I'd like to see an ethernet unit that used the same modules as the TDM400P. Could even be a couple of models: a 6 port, 12 port, and 24 port. Don't know about the 24 port unit as a channel bank eats into that market. The 6 and 12 port modules would be perfect for soho and small business that don't need the port density of a full blown channel bank. This is the market that Asterisk is AWESOME for. Stick * on a small embedded linux box like a linksys router and plug in a 6-port IAXy with 4 FXS and 2 FXO. Need to expand? Add another 6 port IAXy. The modules for the TDM400P are economical enough to do this with and beat out pricing of most of the larger (more than 2 port) SIP gateways AND already have certification (or pending certification.) Of course the big bonus is IAX instead of SIP. Frankly, with all the interupt issues with PCI, especially if you need more than one card, a low-port density alternative to the TDM400P is needed. This should really increase the volume of Digium's sales as there would be a better alternative to the SPA-2000 and 3000. Increased volum drives down the cost of the modules (which if they were made in china should drop to ~10-20 each.) Another reason for going small (6 port) is that you can use a embedded low-power inexpensive processor for codec processing and keep it inexpensive.

It does have an ethernet port and can take an IP but it seems to know nothing about any kind of connection between the DS0s and ethernet. -A.

[Asterisk-Users] Re: Ethernet Channel Bank idea
I hate to waste bandwidth by saying ditto but, big ditto. This would be a great boon for Asterisk. Medium sized installs especially. On the very small side you can slap an FXO port or two in your server and your 4 SIP phones can share without much of a problem. As I see it, the issue comes with the installs just above this. When you need 4 or 6 FXO ports and you also want a some FXS ports, now you are looking at trying to stuff 3 loaded PCI cards into a box. Installing a mux for 9 ports seems like a bit overkill but is really your only option in many cases. The other problem is that, between the T100P and the mux, your bill is getting fairly large (I do not personally know where the $100 channel banks are, especially with a mix of FXO and FXS ports). An Ethernet channel bank would be great, especially to fill this niche. I think the post below hits it on the head. IAX2 back to the server, modular ports, various sized cages...wow. The SBC availability or SNMP monitoring would just be icing on the cake. A dumb box-o-ports is really all that is necessary. IAX2 over Ethernet is the new T1!!
