Hi again, Andrew, folks, Yup - the X100P (or clone) is a PSTN card for use with single lines. Fine device, and WAY cheaper than a TDM4xx with a single populated FXO module (TDM01B), at least in the UK.
I assumed that you weren't seriously suggesting a TDM01B for a single analogue line (if they weren't back-ordered). Hence I guessed that the use case is "a few lines".
AFAICT, the TDM4xx modules don't do busy detection or call supervision or CLI or have settings for correct impedance right now for use in the UK - all we have is the *potential* to get these working sometime in the *future*.
If one does need a couple of lines, then one may have a choice - PSTN access or ISDN access.
In civilised countries (i.e. not here) it's cheaper to get a BRI than it is to get two analogue lines. Thus, if one needs more than one analogue line, it may be cheaper to go for a BRI from your Comms Provider.
If you DO go for a BRI (or a pair of BRIs) the card(s) WILL be cheaper (and, most important, it works, out of the box).
No grief with whether or not CLI works - it does now. Likewise, no grief about progress/call supervision - it works over here right now.
To sum up, if the use case is more than one line and you don't live in the U.S of A., then don't forget ISDN - it has several advantages (not least of which is that we don't do SPIDs over here).
If the use case is a single analogue line, then the price of an under-populated TDM4xx puts it outside the budget for most people - it's just too expensive at current UK reseller prices.
all the best, Lawrence

Why? Does progress tone/call supervision/CLI work in the UK for the TDM4xx? (at least now CLI works with the X100P :).
The TDM card is a true Digium product, not an OEM card resold by Digium. IIRC
the FXO module is far higher quality too.
In my experience, ISDN works very well with Junghanns's excellent chan_capi (and the AVM passive cards are cheaper) so if a couple of lines is all you need, ...
The X101P doesn't support ISDN. I thought we were talking PSTN here not ISDN?
