HIGH DENSITY VT/TU MAPPER
AND M13 MULTIPLEXER
Sꢀ Allows SW to force the AIS insertion on a per tributary basis.
Sꢀ Inserts valid H4 byte and all-zeros fixed stuff bytes. Remaining path overhead
bytes (J1, B3, C2,G1, F2, Z3, Z4, Z5) are set to all-zeros.
Sꢀ Inserts valid pointers and all-zeros transport overhead bytes on the outgoing
telecom Add bus, with valid control signals.
Sꢀ Support in-band error reporting by updating the FEBE, RDI and auxiliary RDI
bits in the V5 byte with the status of the incoming stream and remote alarm
pins.
Sꢀ Calculates and inserts the tributary path BIP-2 error detection code for each
tributary.
SONET/SDH VT/TU Mapper Section:
Sꢀ Inserts up to 28 bit asynchronous mapped VT1.5 virtual tributaries into an
STS-1 SPE from T1 streams.
Sꢀ Inserts up to 28 bit asynchronous mapped TU-11 tributary units into a STM-
1/VC4 TUG3 or STM-1/VC3 from T1 streams.
Sꢀ Inserts up to 21 bit asynchronous mapped VT2 virtual tributaries into an STS-
1 SPE from E1 streams.
Sꢀ Inserts up to 21 bit asynchronous mapped TU-12 tributary units into an STM-
1/VC4 TUG3 or STM-1/VC3 from E1 or T1 streams.
Sꢀ Bit asynchronous mapping assigns stuff control bits for all streams
independently using an all digital control loop. Stuff control bits are dithered to
produce fractional mapping jitter at the receiving desynchronizer.
Sꢀ Sets all fixed stuff bits for asynchronous mappings to zeros or ones per
microprocessor control
Sꢀ Extracts up to 28 bit asynchronous mapped VT1.5 virtual tributaries from an
STS-1 SPE into T1 streams via an optional elastic store.
Sꢀ Extracts up to 28 bit asynchronous mapped TU-11 tributary units from an
STM-1/VC4 TUG3 or STM-1/VC3 into T1 streams via an optional elastic
store.
Sꢀ Extracts up to 21 bit asynchronous mapped VT2 virtual tributaries from an
STS-1 SPE into E1 streams via an optional elastic store.
