Overview
The DPS TL1 MUX-8 is a specialized data multiplexer for
combining up to 8 data lines using Bellcore (tm) Transaction
Language 1 (TL1) onto a single TL1 line. By observing the de-
lineating semi-colon at the end of each TL1 data packet, the
processor in the TL1 MUX-8 is able to store and stack incom-
ing data. The TL1 packets are then sent to the common port in
the order received and transmitted to the interrogator
one-at-a-time. AID and TID information, as well as alarm data,
remains intact, giving the interrogating element manager undis-
turbed and complete alarm data. Incoming packets are stored in
a 256 K buffer. Packets from the interrogator side are broadcast
to all network elements, with full address information.
The TL1 MUX-8 consists of nine interface ports intercon-
nected and controlled by a processor. Associated with each port
is a “docking module” socket that allows the physical interface
to the outside world to be configured to match the associated
communications channel or device. The TL1 MUX-8 is avail-
able with 202T Modems or RS 232 interfaces on each port.
Other models are available with RS 422/485 and TTL inter-
faces, or to accept plug-in 202 and 212-type modems. The mo-
dems are sold separately so that each port can be equipped with
the desired type modem.
The TL1 MUX-8 is housed on a plug-in board that fits in a
1-3/4" rack-mount housing. The back of the housing provides
DB9 connectors for connecting the associated devices. The ac-
tual MUX board can be changed rapidly without removing any
of the connections.
The front panel of the TL1 MUX-8 provides LEDs for moni-
toring unit activity and a craft port for configuration. There is a
fuse alarm indicator on the front panel and a fuse alarm output
relay that activates when the fuse blows.
The MUX is configured locally with T/MUX software run-
ning on a PC. T/MUX software is included with the MUX.
The TL1 MUX-8 operates on either -24 or -48 Volts DC, de-
pending on the option. (Options are described in the Options
and Model Numbers section of page 8.)
