Alarm Generation
TC-RDI (Tandem Connection - Remote Defect Indication): Generates a
TC-RDI defect. Bit 8 of the N1/Z6/N2 byte multiframe 73 is set to "1".
ODI (Outgoing Defect Indication): Generates a ODI defect. Bit 7 of the
N1/Z6/N2 byte frame 74 is set to "1".
TC-IAIS (Tandem Connection - Incoming Alarm Indication Signal):
Generates an incoming AIS defect.
For HOP: Bits 1 through 4 of the N1 byte are set to "1110".
For LOP: Bit 4 of the Z6/N2 byte is set to "1".
TC-LTC (Tandem Connection - Loss of Tandem Connection):
Generates a wrong FAS multiframe indicator sequence.
TC-UNEQ (Tandem Connection - Unequipped):
For HOP: Generates an all "0"s pattern in the higher order path signal
label byte (C2), the TCM byte (N1) and the path trace byte (J1), and a
valid BIP-8 bytes (B3).
For LOP: Generates an all "0"s pattern in the lower order path signal
label (bit 5, 6, 7 of byte V5), the TCM byte (Z6/N2) and the path trace
byte (J2), and a valid BIP-2 (bits 1, 2 of V5 byte).
TC Access Point Identifier
Message allows the selection of the APId (Access Point Identifier) message
to be generated. Up to 15 characters are allowed (a CRC-7 byte will be
added in front for a total of 16 bytes). The default setting is EXFO TCM.
Note: The message value should be ACSII suitable characters.
