Actually, I was referring specifically to the situation with ISDN.
Instead of having a pile of serial controllers, a pile of Bitsurfrs, a
pile of power bars, a pile of serial cables and a pile of phone
cables, get yourself a Portmaster with BRI cards or if you're a larger
operation, something like an Ascend MAX series and run BRI's and PRI's
right into the box. Looking at our machine room, the most problematic
area is the nest of cabling and wires between the modems, the
Portmasters and the bix blocks. I'd love to be able to plug a single
cable into a PRI port and be able to run 23 B channels from there. No
fuss no muss.

I forgot... I also have a regular analog phone connected to the
modem, which serves as a second voice line. :) For the price, a
Bitsurfr is flexible and ideal for casual home use.
