Cell Site Hardware LED Descriptions
DFI 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 DFI is
insane.
Yellow Lighted if the DFI detects an alarm
other than a minor, misframe, or slip
alarm on the connected T1 line, or
other than a 10e-6 error-ratio or slip
alarm on the connected E1 line.
Green The DFI selected as the synchroni-
zation reference for the TDM bus
(TDM0, TDM1) has this LED lighted;
only one DFI (or DS1) on the TDM
bus can have the green LED
lighted; if the local oscillator on the
CAT is the synchronization refer-
ence, no DFI (or DS1) will have its
green LED lighted for the bus.
Note:
TDM buses are always installed
"red stripe up."
CAT 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 CAT has a
board error or is insane.
Green The on-line (active) CAT has this
LED lighted; the off-line CAT has its
green LED off. (The active CAT pro-
vides TDM bus clocks.)
