Line Unit fuse may have blown, or the HDSL line(s)
may be open.

•
TEST LED Indicator

been activated at any unit in the system.
Off—there are no tests activated in the system.
•
FAULT LED Indicator
Red—there is a fault in the system.
Off—no faults are detected in the system.
•
ACO Pushbutton
Pressing this pushbutton will silence any audible
indicators in the central office resulting from a PG-
Flex major or minor alarm. This pushbutton also
functions as an LED test by turning on all LEDs
when pressed and held for at least 2 seconds. When
the pushbutton is released, LEDs resume their
normal status indications. The LEDs remain active
for 2 minutes, at which time the channel unit LEDs
turn off to conserve power at the remote terminal.
•
RS-232 DB-9F Connector
This connector is used by technicians to check the
configuration and status of the PG-Flex. This is a
DCE interface and requires DTE active from the
terminal to prevent automatic log off.
