VERY IMPORTANT!!! Determine what type of TX102, TX104, or
TX108 you have purchased. There are two different types of Telplex:
multi-drop
(Rev. 3.03) and
standard
(Rev. 1.04). Multi-drop units are
identified by a
TYPE A
sticker on the rear panel. Standard units do
not have a
TYPE A
sticker. Certain parts of this manual will pertain
only to a multi-drop unit and not the standard unit or vice versa. You
will be instructed to disregard certain parts of this manual if the
corresponding information is not relevant to a specific type of Telplex.
The Telplex TX102, TX104 and TX108 statistical multiplexer (stat
mux) units are used to link EIA-232 serial devices (e.g., computers,
terminals and printers) located at multiple sites together over single
telephone lines or cables. Such devices are connected to
terminal
ports
on the Telplex. A local TX102, TX104, or TX108 is connected to
a remote Telplex via a
composite port
.
The remote Telplex may be a TX102, TX104, TX108, TX4, TX28, or
TX60 for multi-drop units. The TX28 and TX60 are expandable units
that may have up to twenty-eight and sixty terminal ports respectively.
The TX28 and TX60 may have multiple composite ports installed to
allow connections to multiple sites. A standard TX102, TX104, or
TX108 will connect to an identical unit at the remote site.
The TX102, TX104, or TX108 will multiplex two, four, or eight lines of
data respectively. The multiplexed data is sent sequentially over a
single telephone line or cable via the local unit's composite port. The
data is automatically demultiplexed by a remote Telplex with
distribution of data to designated terminal ports.
