Cell Site Hardware LED Descriptions
CPI x
Red Lighted momentarily during the
self-test initiated upon powerup or
after a system reset and is off after
successful completion of the
self-test; lighted during normal oper-
ation if software detects a CPI fail-
ure or the CPI is insane.
NCI x
Red Lighted momentarily during the
self-test initiated upon powerup or
after a system reset and is off after
successful completion of the
self-test; lighted during normal oper-
ation if there is no valid TDM bus
clock source or the NCI is insane.
DS1 x
Red Lighted during the self-test initiated
upon powerup or after a reset and
goes off after successful comple-
tion of the self-test; lighted during
normal operation if the DS1 is
insane.
Yellow Lighted if the DS1 detects an alarm
other than a minor, misframe, or slip
alarm on the connected T1 line.
Green The DS1 selected as the synchroni-
zation reference for the TDM bus
(TDM0, TDM1) has this LED lighted;
only one DS1 (or DFI) on the TDM
bus can have the green LED
lighted; if the local oscillator on the
CAT is the synchronization refer-
ence, no DS1 (or DFI) will have its
green LED lighted for the bus.
Note:
TDM buses are always installed
"red stripe up."
