Is there any way to test an internal or external modem
without anything
except broadband or cellular connections?
It depends if "without anything" is referring to "no additional phone
line / service from an external 3rd party" or "nothing at all added to
the mix".
I know I can't test the acoustic modems, but I was
hoping to be able
to test internal ISA and PCI, as well as external modems from 300
baud to 56k. Perhaps there is some inexpensive gizmo available?
It should be quite possible to test slower modems. However, faster
speeds, 14.4 / 19.2 / 28.8 / 33.6 / 56, will be more problematic to test.
People are reliably getting modems to connect across VoIP using lossless
CODECs, i.e. ULAW / ALAW.
This does take some effort to (initially) set up. But it should be
quite serviceable once it is set up.
I think that some companies make Analog Terminal Adapters (ATA) that
have two ports, one would connect to each modem, and any number dialed
would call (ring) the other port. I /think/ that Grandstream used to
make a Handy Tone that did this. Again, this will take some configuration.
I routinely (almost daily) see @Level29_BBS talking about dialing in
across VoIP.
