HP-TC-AIS
Tandem Connection-Alarm Indication Signal. Indicates if IEC
bits 1110 are being received from upstream TCM equipment.
(Bits 1-4 of the N1 byte are the IEC bits.) This is an alarm
LED.
HP-TC-UNEQ
Tandem Connection-Unequipped. Indicates that a 00h
pattern has been detected in the N1 byte of a Tandem
Connection. This is an alarm LED.
HP-TC-LOF
Tandem Connection-Loss of Frame. Indicates the loss of a
valid multiframe frame alignment signal (FAS) pattern from
upstream TCM equipment. This is an alarm LED.
The following describes the TCM LEDs that appear when the
TC Overhead
Processing
is configured for "
LP Enable
".
LED
Description
LP-TC-BIP
Tandem Connection-Bit Interleaved Parity error. Indicates a
BIP error count is being received from downstream TCM
equipment. Bits 1-2 of the N2 byte are used for this indicator.
This is an error LED.
LP-TC-REI
Tandem Connection-Remote Error Indication. Indicates that
an error has occurred at the downstream TCM equipment.
The unit is receiving an error. Bit 5 of the N2 byte is used for
this indicator. This is an error LED.
LP-TC-OEI
Tandem Connection-Outgoing Error Indication. Indicates that
the unit is sending an OEI error to upstream TCM equipment.
Bit 6 of the N2 byte is used for this indicator. This is an error
LED.
LP-TC-RDI
Tandem Connection-Remote Defect Indication. Indicates that
a defect has occurred at the downstream TCM equipment.
The unit is receiving an alarm. Bit 8 in multiframe 73 of the
N2 byte is used for this indicator. This is an alarm LED.
LP-TC-ODI
Tandem Connection-Outgoing Defect Indicator. Indicates that
the unit is sending an ODI alarm to upstream TCM
equipment. Bit 7 in multiframe 74 of the N2 byte is used for
this indicator. This is an alarm LED.
LP-TC-AIS
Indicates that the unit is sending an AIS alarm to upstream
TCM equipment. Bit 4 of the N2 byte is used for this indicator.
This is an alarm LED.
