HIGH DENSITY VT/TU MAPPER
AND M13 MULTIPLEXER
Sꢀ Line side interface is from the SONET/SDH Drop bus via the VT2 or TU-12
demapper.
Sꢀ System side interface is either serial clock and data or SBI bus.
Sꢀ Provides external access for up to two de-jittered recovered E1 clocks.
SONET/SDH Tributary Path Processing Section:
Sꢀ Interfaces with a byte wide Telecom Add/Drop bus, interfacing directly with
the PM5362 TUPP-PLUS and PM5342 SPECTRA-155.
Sꢀ Compensates for pleisiochronous relationships between incoming and
outgoing higher level (STS-1, AU4, AU3) synchronous payload envelope
frame rates through processing of the lower level tributary pointers.
Sꢀ Optionally frames to the H4 byte in the path overhead to determine tributary
multi-frame boundaries and generates change of loss-of-frame status
interrupts.
Sꢀ Detects loss of pointer (LOP) and re-acquisition for each tributary and
optionally generates interrupts.
Sꢀ Detects tributary path alarm indication signal (AIS) and return to normal state
for each tributary and optionally generates interrupts
Sꢀ Detects tributary elastic store underflow and overflow and optionally
generates interrupts.
Sꢀ 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.
Sꢀ Detects tributary path signal label unstable alarms (PSLU) and return to
stable state for each tributary and optionally generates interrupts.
Sꢀ Detects assertion and removal of tributary extended remote defect indications
(RDI) for each tributary and optionally generates interrupts.
Sꢀ Calculates and compares the tributary path BIP-2 error detection code for
each tributary and configurable to accumulate the BIP-2 errors on block or bit
basis in internal registers.
Sꢀ Allows insertion of all-zeros or all-ones tributary idle code with unequipped
indication and valid pointer into any tributary under SW control.
