I am in the process of upgrading our dialup modems, most likely with some
combination of 9600bps and 2400bps modems.  Our telephone switch cannot
handle async speeds over 19.2kbps.  Therefore, the potential 38.4kbps
throughput of V.32/V.42bis modems would probably be wasted.  Is there any
other reason to go with V.42bis on our V.32 modems?

As for 2400bps, for standard dialup applications, is there much to gain by
choosing V.42bis over MNP5?  We plan on setting the DTE rate at a constant
9600bps regardless of the actual speed of the connection.

Finally, does anyone have a recommendation for inexpensive (but reliable)
V.32 and 2400bps modems, preferably rack-mountable, that can be set to a
"manual" mode (where the modem plays dumb and allows our PBX to control it).

Any info would be appreciated...
