The multiplexer combines data traffic from up to eight sources into a high-speed
composite link. Channel speeds supported are from 75bps to 19,200bps with an
automatic channel speed detection (AUTOBAUD) option up to 9,600bps. The
buffer management allows storage of 16K bytes to be shared on demand by the
channels. Each channel is assigned a minimum of 372 bytes of buffer space to
prevent lockout. Because of the buffering action of the 2031, the data rates on the
channel side of the multiplexer may total several times the actual link rate without
data loss. The multiplexer will handle an aggregate of 76,800 bps in constant full-
duplex traffic (with flow control) and a 64,000K bps link without loss of data.
The multiplexer can transmit control messages end-to-end to handle such things
as break propagation, EIA signal propagation, and autobaud speeds. The control
messages are transparent to the user. In addition, any of the EIA interface outputs
can be forced high or low through the user interface.
Multiplexer configuration and operation monitoring is accomplished in a variety
of ways. An ASCII asynchronous terminal can be attached to the supervisory port
on the back panel or to a data channel that has the supervisory access enabled, or
the front panel push-buttons and LCD display can be used. Another method of
access is from a remote multiplexer in a point-to-point or a DCX network applica-
tion. Access to the supervisory function can be password protected for security.
All parameters are contained in nonvolatile storage.
The 3028 Turbo (CTS 3028 Turbo (CTS 2031 Turbo))
multiplexer is designed to be a
cost-effective point-to-point multiplexer. At the same time, it is fully compatible
with the CTS 2031 and the AT&T Paradyne DCX family of multiplexers and can
serve as an 8-channel node in a DCX network.
