Yes, I had a test system with a TDM400P and two FXO modules terminating two BT Featureline Compact lines. However, "had" is the operative word. One of the two FXO modules is now holding the line permanently off-hook - even when the system is powered down. The other module is fine, and the drivers don't see anything wrong with either module. My suspicion is that the one module is dead. I haven't had a chance to pull out the machine and play with it, though. To see if you have a similar problem, connect a phone in parallel with the FXO module. Unplug the module from the line, and check that you get a dial tone with the handset. Hang up, and plug the FXO back in. Then lift the handset again - I get a noisy line with a very quiet dial tone. If you wait long enough, the dial tone will stop and you'll hear the screamer, again very quiet. I've no idea what caused our fault. I don't know of any storms before the failure, and all the other connected equipment is fine.

It's probably worth trying another filter, in case there's a fault with your current one.

That's not terribly suprising. I've noticed a significant effect on ADSL sync speed by connecting a TDM400P through an inferior quality filter. > If I plug it through an ADSL filter, the line > no-longer detects hang ups. I can't say I've noticed that, but the system isn't in service yet. Do you have an alternative ADSL filter you can try? Of the selection I had available, I found the Speedtouch-branded units were the best.

I'm working with refurbished hardware, so don't have much freedom of choice in motherboards. I'm planning on using a fairly good Intel dual- socket-370 server board, but I can't afford to make the wrong choice. > even though the software installation > instructions leave much to be desired for the > inexperienced, Is that inexperienced in telephony, or inex- perienced in Linux?

That's a good point in favour of the A200 - it's cheap to add the hardware echo canceller if it's needed.

[Asterisk-Users] Digium TDM400P vs Sangoma A200 for 2 x FXO
Evening all. I'm looking at building an Asterisk system for one of the projects of the Charity where I'm the SysAdmin. The project has two analogue phone lines - BT Featureline Compact, we're in the UK - that I'd like Asterisk to handle. My current quandary is which FXO interface to use. I've been looking at the Digium TDM400P and Sangoma A200, which are similar prices for two FXO lines. Can anyone comment on the relative merits of those two devices? Are there any other options in the same price range? As we're a small Charity, price is a major consideration. I don't think we can afford the A200's hardware echo-canceller, for instance. Thanks for your help.
