With 25-pin connectors, I'd guess serial ports. They may have full modem
control signals, but I don't think you have any modems internal to the unit.
Unless this is where the RS-232 fed in, and you have RJ connectors on the
other side.

Modem ports would probably be a RJ connector, or screw terminals.
I have seen some modems with a 9-pin connector (MultiTech rack
mount). Some really old devices I used had 25 pin connectors, but this
doesn't look as badly built as those were.
