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…
Link isn't too informative, the product page may be better: https://www.sysmocom.de/products/lab/icE1usb/ Given osmocom's focus I guess the main point to this for them is talking to base stations that have an e1 port.
Indeed, interfacing legacy GSM base stations is the primary use case. However, you can jsut as well use it to interface any other type of E1 equipment, like PBXs etc.
Would it be as simple as writing some high level software that interfaces with readily available libraries or would more possibly be necessary?
I’m fascinated by the opportunity that all of the legacy circuit switched(pardon me and my naïve googling if that’s the wrong term) hardware has left in critical places.

What's the project?
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.
