HIGH DENSITY VT/TU MAPPER
AND M13 MULTIPLEXER
1
FEATURES
Sꢀ Integrates a SONET/SDH VT1.5/VT2/TU11/TU12 bit asynchronous mapper,
a full featured M13 multiplexer with DS3 framer, and a SONET/SDH DS3
mapper in a single monolithic device for terminating DS3 multiplexed T1
streams, SONET/SDH mapped T1 streams or SONET/SDH mapped E1
streams.
Sꢀ Five fundamental modes of operation:
Sꢀ Single STS-1, AU3 or TUG3 Bit Asynchronous VT1.5 or TU-11 Mapper
with ingress or egress per tributary link monitoring for 28 T1s.
Sꢀ DS3 M13 Multiplexer with ingress or egress per link monitoring for 28 T1s.
Sꢀ Up to 28 DS3 multiplexed T1 streams are mapped as bit asynchronous
VT1.5 virtual tributaries or TU-11 tributary units, providing a
transmultiplexing (“transmux”) function between DS3 and SONET/SDH
with ingress or egress per tributary link monitoring for 28 T1s.
Sꢀ Single STS-1, AU3 or TUG3 Bit Asynchronous VT2 or TU-12 Mapper with
ingress or egress per tributary link monitoring for 21 E1s or 21 T1s.
Sꢀ Up to 21 E1 streams multiplexed into a DS3 following the ITU-T G.747
recommendation. This E1 mode of operation is restricted to using the
serial clock and data system interfaces.
Sꢀ Up to 28 VT1.5/TU11 or 21 VT2/TU12 tributaries can be passed between the
line SONET/SDH bus and the SBI bus as transparent virtual tributaries with
pointer processing.
Sꢀ When adding and dropping T1 or E1 tributaries the mapper and demapper
blocks allow for up to 28 VT1.5/TU11 or 21 VT2/TU12 tributaries to be
processed from any tributary location within the full STS-3/STM-1. On the
telecom DROP bus side this requires that the STS-3/STM-1 be in locked
mode such that the J1 bytes immediately follow the C1 bytes.
Sꢀ Supports a byte serial Scaleable Bandwidth Interconnect (SBI) bus interface
for high density system side device interconnection of up to 84 T1 streams,
63 E1 streams or 3 DS3 streams. This interface also supports transparent
virtual tributaries when used with the SONET/SDH mapper.
Sꢀ Provides jitter attenuation in the T1 or E1 receive and transmit directions.
