<>The December issue of "Teleconnect" (a telephone interconnect
industry publication - Harry Newton, Publisher) has a roundup on
Data PBXs.  They are enthusiastic about these things, and after
a general discussion (semitechnical) they have short discussions
(~1-2 pages each) about a number of data PBX manufacturers.  The
discussions briefly discuss the origin of the company and the
type of products made.

  The companies covered are:
M/A-COM - developed data pbxs to support their data comm/microwave 
MICOM - also does stat muxes, have acquired Interlan
DEVELCON - old timer in data pbx; will switch synch and asynch
GANDALF - started with port selectors in 1972, broad product line
INFOTRON - high aggregate data rate data pbxs
WESTERN TELEMATIC - very small data pbxs

  There are a number of new active companies which they didn't
cover (like Network Products and Equinox.)

  I found it interesting that *both* M/A-Com and Infotron claim
to have the largest (in terms of number of lines) data PBX on
the market.  (M/A-Com's IDX 3000 has a capacity of 3,072 lines,
while Infotron's INX4400 has a capacity of 4,000 lines.)

  Teleconnect makes a point of the price advantage of data pbxs
(often as low as $100-$150 per channel) vs. either LANs or
voice/data pbxs.
