DESCRIPTION

The PM5366 High Density 84/63 Channel VT/TU Mapper and M13 Multiplexer (TEMAP-84) is a feature-rich device for use in any applications requiring high density link termination over T1 and E1 (G.747) channelized DS3 or T1 and E1 channelized SONET/SDH facilities.

FEATURES

• Integrates three SONET/SDH VT1.5/VT2/TU11/TU12 bit asynchronous or byte synchronous mappers, three full featured M13 multiplexers with DS3 framers, three E3 framers, and three SONET/SDH DS3 mappers in a single monolithic device for terminating 84-1.544 Mbit/s or 63-2.048 Mbit/s data streams.

• Each SPE/DS3 independently programmable to allow the following modes of operation:

• Five T1 modes of operation:

• Three STS-1, AU3 or TUG3 Bit Asynchronous VT1.5 or TU-11 Mappers with ingress or egress per tributary link monitoring.

• Up to 84 T1 streams mapped as byte synchronous VT1.5 virtual tributaries into three STS-1 SPEs or TU-11 tributary units into three STM-1/VC3 or TUG3 from a STM-1/VC4.

• DS3 M13 Multiplexer with ingress or egress per link monitoring. Includes the option to asynchronously map the DS3s into three STS-1/STM-0 SPEs.

• Up to 84 DS3 multiplexed 1.544 Mbit/s streams are mapped as bit asynchronous VT1.5 virtual tributaries or TU-11 tributary units, providing a transmultiplexing function between DS3 and SONET/SDH.

• Up to 63 T1 streams mapped as bit asynchronous TU-12 tributary units into three STM-1/VC3 or TUG3 from a STM-1/VC4.

• Four E1 modes of operation:

• Three STS-1, AU3 or TUG3 Bit Asynchronous VT2 or TU-12 Mappers with ingress or egress per tributary link monitoring.

• Up to 63 E1 streams mapped as byte synchronous VT2 virtual tributaries into three STS-1 SPE or TU-12 tributary units into a STM-1/VC3 or TUG3 from a STM-1/VC4.

• Up to 63 2.048 Mbit/s streams multiplexed into three DS3s following the ITU-T G.747 recommendation. Includes the option to asynchronously map the DS3s into three STS-1/STM-0 SPEs.

• Up to 63 DS3 multiplexed 2.048 Mbit/s streams are mapped as bit asynchronous VT2 virtual tributaries or TU-12 tributary units, providing a transmultiplexing function between DS3 and SONET/SDH.

• Two unchannelized DS3 modes of operation:

• Standalone unchannelized DS3 framer mode for access to the entire DS3 payload.

• Up to three DS3 streams are mapped bit asynchronously into VC-3s.

• Standalone unchannelized E3 framer mode (ITU-T Rec. G.751 or G.832) for access to the entire E3 payload.

• Up to 84 VT1.5/TU11 or 63 VT2/TU12 tributaries can be passed between the line SONET/SDH bus and the SBI bus as transparent virtual tributaries with pointer processing.

• 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, 3 DS3 streams or 3 E3 streams. This interface also supports transparent virtual tributaries when used with the SONET/SDH mapper.

• Supports insertion and extraction of arbitrary rate (eg. fractional DS3) data streams to and from the SBI bus interface.

• Provides jitter attenuation in the T1 or E1 receive and transmit directions.

• Provides three independent de-jittered 1.544 MHz or 2.048 MHz recovered clocks for system timing and redundancy.

• Provides per link diagnostic and line loopbacks.

• Provides an on-board programmable binary sequence generator and detector for error testing at DS3 and E3 rates. Includes support for patterns recommended in ITU-T O.151.

• Also provides PRBS generators and detectors on each tributary for error testing at 1.544 Mbit/s and 2.048 Mbit/s rates as recommended in ITU-T O.151 and O.152.

• Supports the M23 and C-bit parity DS3 formats.
