I actually have a bunch of converters.
2 are Black Box level converters with some basic diagnostics and I also
have an odd bunch of cenverters I presumed to be modems.

They look like wall-wart power transformers and have a 9 pin DIN plug
and 2 modular phone type connectors on the bottom and no real markings.

I bought them surplus from someplace I once worked.

I presumed they were modems and got them for embedded/home automation
type projects.
I tore one apart and realized they weren't modems and the ICs in them
were 422 converters.

The current firmware on my router may support a telnet connection
after it is configured and given an IP address.

Another issue is the router sends status info and telephone/ISDN
info out the serial port and I'd like to interface that to a homebuilt
PBX system.

I am a bit concerned about the security issues, but it is not that
big of a worry to me.
