- Here's an arrangment I would like to see:
-
- customers | POTS | C.O. | ISDN link | my house
-
- end user modem ------ modem --|-------------|
- end user modem ------ modem --| |
- end user modem ------ modem --| multiplexer | +---------------+
- end user modem ------ modem --| |=========| my BBS server |
- end user modem ------ modem --| | +---------------+
- end user modem ------ modem --|-------------|
-
- I don't see how we could eliminate the modems, but we should be able to
- move them to the c.o., and have only one 2B+D line from the c.o. to the
- host, no?
-
- Does anybody know what one would need to put in my box labelled
- 'multiplexer?' Of course, we would also need some sort of demultiplexing
- ISDN software/hardware in the host. In theory, one should be able to
- multiplex 8 v.32bis lines (8 x 14.4 = 115.2) into one 2B+D connection.
- That would sure cut down on phone bills!
-
- I have no idea what this would take. Just an idea....
