The volume of news is getting pretty high, and phone bills are starting to soar. I recall there was some interest expressed a while back about using 2400 baud modems to cut the cost in half, but there wasn't enough serious interest. Now with volume so high, it may well be worthwhile. How would the backbone sites feel about each buying one 2400 baud modem (presumably with auto-answer/auto-dial capabilities) and using that for (at least) their news backbone links. I'm guessing such a modem would cost around $2000, but this figure may be high. I haven't looked into what's available. Selection of which modem is important. From what I can see, there hasn't been any standard emerging, and I don't see any signs of one. So in effect we will be setting a standard by choosing one. We might even be able to go to 4800 baud if there is a wonderful modem available. We should make the choice carefully. Mark Horton

I know we're seriously interesting in getting a 2400-baud modem. The
one we are looking at in particular is the Concord Data one. The choice
is partly a matter of compatibility -- one of our news feeds, linus,
already has them -- and partly a matter of cost. The Concord Data
modems are not noticeably more expensive than triple modems (although
they lack 300 baud and R-V 1200 protocol), whereas the R-V quadruple
modems are outlandishly expensive and reportedly hard to get delivery
on. We need one more good modem to get rid of our last 300-only line,
and the odds are very good that it's going to be from Concord Data.
(For people who want info... The relevant model is the Concord Data
224 Autodial. It speaks 2400 and 212. The autodialer looks fairly
good. The US price is $1195, rather lower than Mark thought. Concord

Using 2400 baud modems instead of 1200 baud would help, but things could also be improved if we make better use of high-speed dedicated networks. The Bell Labs Interlocation Computing Network has high-speed links between NJ, Chicago, Denver, North Carolina, Columbus, and a few other places. If these could be used more effectively it would probably cut down total network cost, without too much impact on the network occupancy. Bill Stewart, AT&T Bell Labs ------- This is of course my personal opinion, and does not imply any commitment of resources on the part of AT&T Bell Labs, or the Holmdel Comp. Center, (or even myself, for that matter.)

Has anyone modified UUCP to work with (ugh, shudder) half-duplex modems?
Before you barf, please note that 9600 baud DIAL-UP modems (synchronous
only, unfortunately) are now available fairly cheaply (see net.dcom).
Now THAT could help a bit, no?
