On the
AV-OS units, only analog phone lines can be used. Digital phone lines can
damage or destroy the AccuVote's internal modem. It is unknown at this
time as to when we would be able to produce a modem internal to the unit that
could handle digital phone lines. There are adapters available to
connect an analog modem to a digital phone line. I've used them
before. The problem is that they require more to set up than just
switching it on and that's more than we want the pollworker to do.
There might also be "digital line capable" modems available to plug into the
AccuVote's serial port. You'd have to redirect your communication from the
modem to the main serial port. I don't know of the existence of a "digital
line capable" modem but I'm sure that could be looked into if attaching an
external modem to the AccuVote was an acceptable solution.
On the
AV-TS R6 units, the modem's capabilities are limited only by what's available in
PCMCIA card format, and the price you're willing to pay for it. There may
be ballot station software considerations to account for, but others could
answer that better than I.
