Item Function
CHASSIS ID selector
switch
Used to assign the chassis number. Each chassis in the system is assigned a unique
number, starting at 0 and running consecutively.
EXT CLK A and EXT
CLK B connectors
BNC connectors used to obtain synchronization reference clocks for the CT bus from an
external source. The CT bus is the means by which voice and audio data is transmitted
throughout the TMS.
TEST / ON / OFF
switches (slots 5 and 6)
Three position rocker switch used to turn power to the slot on or off, or to test the associated
power supply.
ALARM relays Used to connect to external indicators for major and minor alarms. Common (C), normally
closed (NC), and normally open (NO) contact connections are provided.
EXTERNAL SENSORS
relays
Can be used to connect to external sensors for system indication of up to four separate
events (A,B,C,D). CAUTION: Voltage and current limitations. Do not connect to line
level signals.
PWR ON indicators
(S5, S6, and NIC)
Illuminates green when power is applied to slot or NIC.
NORMAL indicators
(S5, S6, and NIC)
Illuminates green when the module in the associated slot or NIC is operating properly and
there are no alarms or system faults.

indicators (S5, S6, and
NIC)
Flashes yellow when a minor alarm is active for the slot or NIC. Accompanied by audible
indication (beep). To reset, press the RESET switch on the FCP. Use as a troubleshooting
aid - alarms are promulgated to the Alarm Viewer (see Alarm Viewer on page 39).
MAJOR ALARM
indicators (S5, S6, and
NIC)
Flashes red when a major alarm is active for the slot or NIC. Accompanied by audible
indication (beep). To reset, press the RESET switch on the FCP. Use as a troubleshooting
aid - alarms are promulgated to the Alarm Viewer (see Alarm Viewer on page 39).
