INTRODUCTION
The MUX100 is an analog to digital interfacing device. In most applications, it is used to connect different
protocols or interfaces. It can be used to connect international protocols to domestic protocols. It can be used to
enable equipment manufactured in one country to communicate with a domestic network.
The basic configuration of the MUX100 consists of a 3U x 318 mm chassis, which fits into a standard 19 inch
equipment rack. The chassis is equipped with one DSP Module, one CPU Module (to load the protocol and
configuration, perform monitoring functions and provide status and alarm information), one Aggregate Module (to
provide a T1 or E1 interface, and framing), one analog module (i.e. FXS, FXO, 4 wire EM etc.)and one Power
Supply (to provide correct power to each module). Optionally, partial redundancy can be obtained with the addition
of another Power Supply. Addition of a ringing voltage device, will allow FXS cards to ring attached telephones.
2
REDUNDANCY
The addition of analog modules and another DSP can expand the MUX100 to handle up to 30 Voice channels. Full
redundancy can be obtained with the addition of another CPU Module. All modules can be plugged and unplugged
while the power is on and not effect the operation of calls in progress.
3
INTERFACE
The MUX100 can be equipped for either T1 or E1 aggregate modules. The Computer Console Interface provides an
Alarm and a Supervisory Port. The Alarm Port provides form C, dry contact relay outputs. The Supervisory Port
provides the ability to configure the MUX100 and use the Network Monitoring System. The -48 VDC power inputs
are supplied via the DC Input Modules. The DC Input Modules are diode isolated and therefore can be fed from
different power sources for true redundancy.
4
INSTALLATION
The MUX100 can be installed by mounting the unit into a suitable rack and securing it with four screws through the
front mounting brackets. Connect the PCM connections to the Line Interface Module. Connect the Supervisory
Port to a Computer Terminal. Connect the Alarm Port (if used) to the remote monitoring system. Connect -48 VDC
to the DC Input Module. Pinouts of power and DB connectors are shown below.

Apply power to the MUX100 by turning on the power switches on the rear of the unit. The LED indicators on the
front of the unit will turn on. This will indicate the CPU is initializing the unit. All LED’s except the in-service
(and alarm, if any) will turn off. A green LED will remain and ready for service. An opening banner will be
displayed on the computer monitor. The prompt will indicate which CPU is in service. All commands are entered
in lower case letters and must be followed by pressing the enter key. The help command will provide a listing of the
commands needed by an installer, operator or technician.

The "show status" command allows the operator to electronically monitor the condition of the MUX100. This
command gives the operator all the information that would normally be seen if the operator was facing the unit. The
"show status" command indicates each slot, what is populated in that slot, the state of the module, alarm conditions
and clocking information.

The "switchover cpu" command is used to manually switch from the primary to the secondary CPU. This will be
indicated by the in-service LED on the secondary CPU turning on and the primary turning off. This command can
be used to transfer from the secondary CPU to the primary. If there is no secondary CPU installed, the MUX100
will not switch.

The "set timers" command is a global setting for system timers. It is strongly recommended to refrain from
changing these timers unless you fully understand the function of each timer and how it will effect the PSTN
network.

The "config chan (number, , all)" allows the operator to configure the individual channels. Each channel must be
configured to accept a call. The channels can be configured on an individual basis or by using the word "all" in the
place of a number.
The options in the channel configuration menu allow the system to be optimized. The following terms are explained
to allow the user to better understand the use of each option.
Configuration Options:

Rx level (in dBm from -18.5 to +6.9): current 0.0
Changes receive level of the fxs card.
Tx level (in dBm from -18.5 to +6.9): current 0.0
Changes transmit level of the fxs card.

The "reset" command is used to reset the MUX100 after the configuration of all channels. Upon use of this
command, the entire MUX100 will initialize causing all calls in progress to be lost. The new information
configured will be installed from the online CPU. The LED indicators on the front of the Aggregate modules will
turn on momentarily. The opening banner will be displayed on the screen.
7
Alarms
Major alarm contacts are activated when the primary or secondary (if equipped) power supply fails, primary or
secondary (if equipped) Clock fails, primary or secondary (if equipped) CPU fails, any installed Aggregate Module.
Major alarms are also activated in the event of loss of Sync, loss of Multiframe or loss of carrier. Minor alarm
contacts are activated when all 1's (AIS alarm), Multiframe all 1's signal (AIS alarm), Yellow alarm or trunk
Multiframe Yellow alarm OCCURS. The alarm contacts, which are form C dry contacts, can be configured as
normally open or normally closed.
8
LED Indicators
The Central Processor Module is equipped with INS (In-service) indicators. The INS indicator is on during normal
operation. This indicates a module is ready for service.
The Aggregate Modules are equipped with Red, YEL (yellow), AIS and RLSD (received Line Signal Detect)
indicators. The RED indicator becomes active when an out of frame condition occurs for more than 2.5 seconds.
An out of frame condition is declared when the Aggregate Module senses an error in the framing bits or when no
signal is present at the input for 2.5 seconds or more. The red alarm condition is cleared when no out of frame
condition is detected for 2.5 seconds or more. The YEL (yellow) alarm activates when a remote failure is detected.
The yellow alarm is cleared when no remote failure condition is detected for at least 2.5 seconds. The AIS indicator
is activated when a framed or unframed "all-ones" condition is detected. The RLSD (Receive Line Signal Detect)
indicator is activated when a PCM (E1 or T1) is connected properly.
The Power Supply Module is equipped with a -48V IN indicator and a +5V OUT indicator. The -48V IN indicator
is illuminated when -48VDC is applied to the equipment shelf and the power switch for that supply is on. A loss of
-48VDC will cause the -48VDC indicator no to illuminate. The +5VDC is illuminated when +5VDC is available to
each module. The +5VDC is derived from the -48VDC.

Troubleshooting
The MUX100 has built-in non-intrusive test and monitoring capabilities. These capabilities allow the user to
quickly determine if there is a problem and isolate the problem. These software tools reduce down time and cost of
external test equipment.
A loop back can be placed on an individual trunk (E1 or T1) to allow the operator to send the information they are
receiving to the originator. This will not interrupt the information being received by the MUX100. The originator
can now look at the signal they are supplying to the MUX100. The loop back can be placed on either signaling
protocol of the Aggregate Module.
The user must understand the operation of the individual country protocol before making any decisions as to the
nature of a problem or if there is a true problem.

11 Modem Connections
11.1 MUX100 Supervisory Port
The Supervisory port has been designed for use with a dumb terminal connected locally. While it is possible to
connect an external modem to the MUX100, the modem must be configured for use with a serial interface which
provides the physical connections detailed in section Error! Reference source not found. and data port
characteristics detailed in section Error! Reference source not found.. It is the users responsibility to configure
their modem to the physical and port characteristics of the MUX100.
Generally the following are issues which must be addressed. Your choice of modem may have additional
requirements.
1. MUX to Modem connections require a null modem adapter.
2. Enable auto answer. Hayes “AT” command: AT S0=1
3. Disable result codes. Hayes “AT” command: AT Q1
4. Turn local echo off. Hayes “AT” command: AT E0
5. Over-ride Data Terminal Ready (DTR). Hayes “AT” command: AT &D0
6. Disable flow control.
11.2 TSC Flash
TSCFlash program can be used with an internal or external modem connected to a PC. The modem must be set for
the following. Your modem may require additional settings.
1. Turn off flow control
2. serial port rate: 9600 baud
3. parity: none
4. word length: 8
5. stop bits: 1
