As a complete newcomer to Asterisk, Digium and PBX, I have several questions. But I'll start with this. To setup a simple system with only a couple of POTS lines, I gather I will need a TDM400 board with FXO and/or FXS modules. So, a TDM400 card will support up to two analog (POTS) lines? joea
FXO is coming from the PSTN, FXS is what devices connect to (like a analog phone). If you are using VOIP phone then you dont need the FXS modules, just FXO.

So you can handle 4 FXO lines, or 4 FXS, or 2FXO and 2 FXS .... but its recommended to use only one tdm400 card per computer.> > joea > _______________________________________________ > --Bandwidth and Colocation provided by Easynews.com -- > > asterisk-users mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users
a TDM400 card will hold up to four modules, which can be FXO or FXS. depending on the modules purchased you can connect up to four phones (using FXS modules) or four incoming phone lines (using FXO modules), or any combination thereof. joea, j4computers wrote:> As a complete newcomer to Asterisk, Digium and PBX, I have several questions. > > But I'll start with this. > > To setup a simple system with only a couple of POTS lines, I gather I will need a TDM400 board with FXO and/or FXS modules. > > So, a TDM400 card will support up to two analog (POTS) lines? > > joea > _______________________________________________ > --Bandwidth and Colocation provided by Easynews.com -- > > asterisk-users mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users > > > !DSPAM:500,44ee20ea208361132923654! >-- Mojo <mojo@horanappraisals.com> Office Manager, Horan & Company, LLC (907) 747-6666 x112
You will need a TDM400 with an FXO module for each line you want. A TDM400 supports up to four lines or analog stations. For two lines, you should get a TDM04B. -----Original message----- From: "joea, j4computers" joea@j4computers.com Date: Thu, 24 Aug 2006 14:58:21 -0700 To: asterisk-users@lists.digium.com Subject: [asterisk-users] Idiot questions> As a complete newcomer to Asterisk, Digium and PBX, I have several questions. > > But I'll start with this. > > To setup a simple system with only a couple of POTS lines, I gather I will need a TDM400 board with FXO and/or FXS modules. > > So, a TDM400 card will support up to two analog (POTS) lines? > > joea > _______________________________________________ > --Bandwidth and Colocation provided by Easynews.com -- > > asterisk-users mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users >Adam Collard President Digital Telecom of Michigan, Inc. acollard@dtmi.net (517) 233-1072 Direct Office (800) 420-3803 x4101 Office (517) 766-5902 Fax This email may be confidential.

Thanks for all the replies. I take it that with one of these FXO boards, one would need an "IP phone" as there is no FXS ? BTW, cheapest I've seen is $19.95.

I actually had a look at one on ebay. What concerned me was the fact that the seller had set it on a carpet for the pictures. I was concerned about static damage. Too late now, tho. I'm still conflicted about it.

Ah, I forgot to add that. I asked explicitly about warranty and a couple of other things. To me no answer to the warranty question meant no warranty. For the price it sold for, I' rather get a new one. I think one of the $20.00 ebay "OEM"'s in the ticket for now. joea Brandon Galbraith<brandon.galbraith@gmail.com> Boldly Declared: 8/25/2006 3:09 PM:> As long as they provide some sort of DOA guarantee, I wouldn't worry too > much about it. > > -brandon >
