Wow, I was looking for a T1/E1 adapter recently for a side project and couldn’t hardly find anything. Sangoma seems to own most of the cards nowadays, and they’re awfully expensive and just awful in general. The only remotely affordable line for me was the Digium line and the documentation for their DAHDI driver outside the brief read me is basically telling you to contact support. And unless you’re using them for an Asterisk setup (I’m not) community support seems to be useless. I ended up paying around $500 for a single port Digium card which I’m not even sure will be able to do what I want now. Other than the expensive Sangoma lines, I was able to find what seemed like a perfect option from GL, except I was quoted $10k, which wasn’t happening. Only other manufacturer I could remotely find was a company making PRI cards that wanted you to fax or email your credit card info. Nice to know there’s another option now.

- the_only_law 6y agoI have a handful of old ISDN videoconferencing terminals that use the H.320 standard. I’m creating a server that will do things like implement things like multipoint conferencing and bridging to modern video conferencing solutions, although right now I’m stuck decoding the mess of a serial interface they use to connect to the network, which appears to be a slightly non standard V.35 right now. The equipment for the project has been growing. Outside the expensive E1 device, I still need to get what I need to really simulate that line, including some DCE to take whatever the serial interface on the phone is to an E1 line. I’ve also bought a few old protocol analyzers which weren’t completely necessary, but fun if not mildly useful.
