1 1 GENERAL INFORMATION GENERAL INFORMATION
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.
