PROPRIETARY AND CONFIDENTIAL
· Extracts 4-bit codewords from the E1 national use bits as specified in
· V5.2 link indication signal detection.
· Provides performance monitoring counters sufficiently large as to allow
· Provides a two-frame elastic store buffer for backplane rate adaptation that
· Frames to the E1 signaling multiframe alignment when enabled and extracts
· Can be programmed to generate an interrupt on change of signaling state.
· Provides trunk conditioning which forces programmable trouble code
· A pseudo-random sequence user selectable from 2
· Line side interface is the DS3 interface mutiplexed as per the G.747
· System side interface is either serial clock and data or H-MVIP.
· Provides external access for up to two de-jittered recovered E1 clocks.
Each one of 28 T1 transmitter sections:
· May be timed to its associated receive clock (loop timing) or may derive its
· Provides minimum ones density through Bell (bit 7), GTE or “jammed bit 8”

Optionally, updates the performance monitoring counters and interrupts the
microprocessor once per second, timed to the receive line.
