I've not encountered that particular piece, but it sure sounds neat.. and
really complex. The Viking unit gets by with a single PIC micro (I think
it's a 16C84) and a set of 8 DIP switches.
Depending on DIP settings, the last digit of the number you dial on one
port determines the behavior of the "network" and the other port - do you
ring-through normally, with a distinctive ring, with / without Caller ID,
get a busy, get a reorder tone (howler), SIT tones, etc.
The DIP sets basic behaviors, like automatic ring-down (hotline service),
rings then ring-down, and a few other options. Like most Viking products,
it's intended as an accessory for PBX, small / home office or
problem-solving device for an installer or designer. They also handle
paging system integration, call sequencers, etc. line concentrators, etc.

As for modems that are capable of 300 bps calls, as far as I know,

I know I was using a 2400 baud modem to my university during the summer of
'96, too - I'd graduated that year, but my account still worked until
September or so. Faster modems were still relatively expensive, and the
calls weren't free anyway, limiting the amount of time I wanted to spend
online for the few weeks of the year that I wasn't in reach of the campus.

any dialup service should support 300 bps.
Not so, at least not exactly. Most commercial services that support 56k
dialup will have issues with low speeds; back when my university went to
56k in the late 90s, 2400 baud modems like the one I owned at the time
were not supported, and when I phoned to ask why, they were openly
incredulous that anyone would be using something slower than 14.4k
(remember, this was 1996).
