3.4A Card Installation
Install the SCS-100 with the card puller up in any one of the five right hand positions of the modem rack.
Connect the 10 position flat cable between the line card and the processor card.
PIN 1 OF THE FLAT CABLE CONNECTOR MUST BE IN THE SAME POSITION ON BOTH THE LINE
CARD AND THE PROCESSOR CARD.
The line number of the line card is determined by the processor card port number.
3.4B Phone Line Installation
Install the RJ11X cable provided with the line card between the RJ11X connector on the front of the line card to
a customer supplied RJ11X jack. Use a standard 103J voice grade line. A slot is provided in the receiver back
plate for the RJ11X cable to pass through.
The SCS-100 is registered with the FCC, registration number CCK8GW-16197-AL-N;
Ringer Equivalence 1.2.
3.4C Phone Line Monitor
The incoming phone line voltage is monitored when the Line Card is configured for digital dialer operation.
During a loss of phone line voltage, the red Phone Line Fail LED is lit and the alert sounds. The alert can be
silenced by pressing the silence switch on the line card. The LED remains lit until the phone line is restored.
3.4D Configuration for MPX or DD
The SCS-100 can be used for either digital dialer or multiplex communication. To change configuration, set the
four jumpers labeled J1, J2, J3, and J4 to the appropriate position. For multiplex communication, set the jumper
labeled J10 for either 2-wire or 4-wire operation. For 4-wire operation, the yellow and black wires of the RJ11X
cable become the receive pair for multiplex.
Always set Jumper J10 for 2-wire operation when using digital dialer communication.
3.4E Power Monitor LED
The green LED labeled PWR is lit when the power supply on the line card is in a good condition.
3.4F Data Communication LEDs
The six yellow LEDs indicate the condition of the line card during the various stages of communication.
A description of each LED is listed below:
TD Transmit Data On when the line card is transmitting to a panel.
RD Receive Data On when the line card is receiving data from a panel.
CD Carrier Detect On when the carrier tone from the panel is detected on the
phone line.
OL On Line On when a line card configured for digital dialer has answered
the phone line. Not used for MPX.
RG Ring Detect On when ringing voltage is detected on phone line. Not used
for MPX.
DT Data Terminal Ready On when the line card is ready to receive.
