Detects tributary path trace unstable (trail trace identifier unstable) alarms (TIU) and return
to stable state for each tributary and optionally generates interrupts.
Extracts tributary path signal label for each tributary into internal registers and detects
change of tributary path signal label events (COPSL) of each tributary and optionally
generates interrupts.
Provides individual tributary path signal label register that hold the expected label and
detects tributary path signal label mismatch alarms (PSLM) and return to matched state for
each tributary and optionally generates interrupts.
Detects tributary path signal label unstable alarms (PSLU) and return to stable state for each
tributary and optionally generates interrupts.
Detects tributary unequipped defect (UNEQ) and tributary path defect indication (PDI-V).
Detects assertion and removal of tributary extended remote defect indications (RDI) for
each tributary and optionally generates interrupts.
Calculates and compares the tributary path BIP-2 error detection code for each tributary and
is configurable to accumulate the BIP-2 errors, on a block or bit basis, in internal registers.
Calculates and compares the TU3 path BIP-8 error detection code for each TU3 stream and
accumulates the BIP-8 errors, on block or bit basis, in internal registers.
Accumulates TU11, TU12, TU2, and TU3 tributary remote error indications (REI) on a bit
or a block basis, in internal registers.
Allows insertion of all-zeros or all-ones tributary idle code with unequipped indication
(UNEQ) and valid pointer into any tributary under software control. Identifies tributaries on
the Egress Byte-Wide TelecomBus that are in an idle state by an output signal.
Identifies tributaries on the Egress Byte-Wide TelecomBus that are in AIS state by an output
signal. Allows software to force the AIS insertion on a per tributary basis.
Supports inband error reporting by updating the REI, RDI, and auxiliary RDI bits in the V5
byte (G1 in TU3) with the status of the ingress stream.
Detects ingress positive and negative pointer justifications and provides positive and
negative justification counts on a per tributary basis.
Reports per STS-1/STM-0 LOM (Loss of Multiframe) interrupts.
Provides an excessive error defect (DEXC) and signal degrade (SD) alarm status for each
tributary path.
Provides per-TU (VT) user programmable BER thresholds for each DEXC / SD test that
range from 10
Processes Low Order (LO) tributary defects of a SONET/SDH data stream in order to
generate Signal Failure (SF) conditions. LO includes TU3, VT1.5/TU11, VT2/TU12, VT3
or VT6/TU2 payloads. Signal fail detection is configurable on a per tributary basis to
include or exclude LOP, AIS, an aggregated form of AIS, UNEQ, TIM, TIU, PSLM, PSLU,
LOM, SD, and DEXC. Optionally generates an interrupt on a change in signal fail status.
