I'm looking for line (two or four wire) multiplexers, that would allow me to evenly device a 9600 bps line into to two 4800 bps lines, or a 2400 baud line into two 1200 baud lines. I recall the good ol' Bell 209A modem used to have this capability. I CANNOT use Stat-MUX's because its flow control (XON/XOFF/whatever) would make the line non-transparent to the protocol(s) going over it. I need to lines to appear as if they each had a dedicated circuit of their own. Any suggestions for such equipment appreciated. Thanks, Geoff Goodfellow Anterior Technology 415-328-5615 geoff@fernwood.mpk.ca.us

Just to grab one of the catalogs here, I see that Black Box has a 2-channel sync TDM for $245, and 4-channel sync TDM for $425, and a 2-channel async TDM for $495. -- Toby Nixon, Principal Engineer | Voice +1-404-840-9200 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.
