HIGH DENSITY VT/TU MAPPER
AND M13 MULTIPLEXER
Sꢀ Frames to TTC JT-G.704 multiframe formatted J1 signals. Supports the
alternate CRC-6 calculation for Japanese applications.
Sꢀ Accepts gapped data streams to support higher rate demultiplexing.
Sꢀ Provides Red, Yellow, and AIS alarm integration.
Sꢀ Provides performance monitoring counters sufficiently large as to allow
performance monitor counter polling at a minimum rate of once per second.
Optionally, updates the performance monitoring counters and interrupts the
microprocessor once per second, timed to the receive line.
Sꢀ A pseudo-random sequence user selectable from 211 –1, 215 –1 or220 –1, may
be detected in the T1 stream in either the ingress or egress directions. The
detector counts pattern errors using a 24-bit non-saturating PRBS error
counter. The pseudo-random sequence can be the entire T1 or any
combination of DS0s within a framed T1.
Sꢀ Line side interface is either from the DS3 interface via the M13 multiplex or
from the SONET/SDH Drop bus via the VT1.5, TU-11, VT2 or TU-12
demapper.
Sꢀ System side interface is either serial clock and data or SBI bus.
Sꢀ Frames in the presence of and detects the “Japanese Yellow” alarm.
Sꢀ Provides external access for up to two de-jittered recovered T1 clocks.
Each one of 21 E1 performance monitoring sections:
Sꢀ Frames to ITU-T G.704 basic and CRC-4 multiframe formatted E1 signals.
The framing procedures are consistent ITU-T G.706 specifications.
Sꢀ Provides performance monitoring counters sufficiently large as to allow
performance monitor counter polling at a minimum rate of once per second.
Optionally, updates the performance monitoring counters and interrupts the
microprocessor once per second, timed to the receive line.
Sꢀ A pseudo-random sequence user selectable from 211 –1, 215 –1 or220 –1, may
be detected in the E1 stream in either the ingress or egress directions. The
detector counts pattern errors using a 24-bit non-saturating PRBS error
counter. The pseudo-random sequence can be the entire E1 or any
combination of timeslots within the framed E1.
