LED Display Status
Dual-color LED indicators on the front panel give mainte-
nance personnel quick diagnostics of the operational status of
the MUX. (ref. Fig. 10) Table G explains the LED functions in
detail.
ACK Button
The ACK button performs an LED test. While the ACK but-
ton is held in LEDs will illuminate in their solid color. The
ALARMS LEDs and TL1 PORTS LEDs will alternately blink
red and green.
Hardware Connections
The illustrations on pages 6 and 7 show wiring pinouts for
the MUX.
Craft Port Connector
The Craft Port is a female RS232 DB9 connector used as a
direct link into the MUX. It is normally used to configure or
monitor the MUX. See Fig. 11.
NOTE: When the craft port is in use the MUX port is not ac-
tive.
