PRISM 3301 Front Panel
Item Function
Power
This green LED illuminates when there is power to the unit and the power supply is operating normally.
Test
This amber LED illuminates when the unit is in loopback or loopup test modes.
Clock Loss
This red LED illuminates when the unit stops receiving the transmit timing clock sent by the DTE.
BPV
This red LED illuminates when a BPV rate greater than 10
-6
ocurs over a one second interval.
PAR ERR
This red LED illuminates when the C-bit parity error rate exceeds 10
-6
for 10 minutes.
REM PAR ERR This amber LED illuminates when the remote unit C-bit parity error rate exceeds 10
-6
for 10 minutes.
TX YEL
This red LED illuminates when a yellow alarm is present.
TX AIS
This red LED illuminates when a signal is transmitted in place of the normal signal to maintain tranmission continuity and
to indicate to the destination terminal that there is a transmission fault at or upstream from the source terminal.
LOSS SIG
This red LED illuminates when a signal loss condition of 128 consecutive zeros is encountered.
LOSS FRM
This red LED illuminates when three errors in 16 conseutive F-bits are detected or when there is an error in the M-bit pat-
tern in two out of three (or two out of four) consecutive M-frames.
RX YEL
This red LED illuminates when a yellow alarm is present.
RX AIS
This red LED illuminates when a signal is transmitted in place of the normal signal to maintain tranmission continuity and
to indicate to the destination terminal that there is a transmission fault at or upstream from the source terminal.
