DPS TL1 MUX-8 User manual

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.)

Typical MUX Applications
The illustration in Fig. 4 shows the TL1 MUX-8 interfacing
8 Network Elements to a T/MonXM WorkStation equipped
with TL1 interrogating ports. The T/MonXM WorkStation is
capable of gathering TL1 messages through as many as 15
ports, displaying the alarm data, filtering it and passing it on to
an OSS.
Shipping List
Verify the following items were included in the shipment:
¤TL1 MUX-8 in a 1 rack unit case
¤2 Mounting Brackets
¤1 Real Fuse; 1 Dummy Fuse (for shipping)
¤Configuration Cable
¤TL1 MUX-8 Operation Guide
Installation
¤Unpack the MUX and all accessories.
¤Attach the mounting brackets for the required rack width.
¤Mount the MUX case to the Rack.
¤Remove fuse
¤WIre wrap models: Connect power wires to the wire
wrap connector J2 at the back of the MUX.
Connectorized models: Connect power wires to the
power terminal block on the back of the MUX. See
Hardware Connections section on pages 6 amnd 7.
¤Connect communications lines to other devices to the
MUX.
¤Verify that the power is correct for the option. (-24 or -48
VDC) See Options and Model Number section at the end
of this Operation Guide.
¤Insert the fuse. (NOTE: Some units are shipped withn a
dummy fuse installed.)
¤Connect the MUX craft port to a PC and load the T/MUX
software. Refer to the Configuration section below for
more information.
¤When configuration is complete, disconnect the
computer. The MUX will continue operation with no
furthur intervention.
Configuration
The MUX is configured with a program callled T/MUX.
T/MUX runs under a host program called T/Config, which can
host configuration software for a variety of DPS products.
T/Config is included on the disk supplied with the MUX
unit. If T/MUX is being run on a computer that already has
T/Config installed, we recommend that you re-install the
T/Config on the T/MUX disk to be sure the latest version is
running.
T/Config and T/MUX Install
Place the T/MUX disk in the A drive and type a:<ENTER>.

Modem Tuning
If the MUX is equipped with modems on any of the ports, set
the modem levels while in the monitor mode. Press F7 to access
the Modem Tuning Window (Fig. 7). Use the + (plus) and - (mi-
nus) keys to select the port (selected port is displayed in the first
field of the window). With a level meter on the port to be ad-
justed, use the keys listed in the window to control the transmit
and raise or lower the level, as needed. The receive portion of
the modem has an AGC input, so requires no adjustment.
NOTE: Do not tune above -4dbm or below -34dBm as the
waveforms become distorted at those levels.
Reports
Use this menu item to run configuration reports to the screen,
printer or file. Such reports are useful in creating records and
reference files. Such files allow future reference to see how a
particular unit is configured. Several configurations can be re-
ported. A query box will ask for starting and ending configura-
tion names (press Tab to see a default box listing of existing
configurations), report destination and file name (if outputting
to file).
Software Parameters
Before a configuration can be downloaded, it is necessary to
set the configuration computer*s com port to match the MUX
craft port parameters. That is done in the Software Parameters
function. See Fig. 9.
A sub-menu appears when this function is selected. Select
“Communications” from this sub-menu. The “Parameters”
item in th sub-menu does not apply to the MUX. Communica-
tions field values are listed in Table E.
