HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
· A pseudo-random sequence user selectable from 211 –1, 215 –1 or 220 –1,
may be inserted into the E1 stream in either the ingress or egress directions.
The pseudo-random sequence can be inserted into the entire E1 or any
combination of timeslots within the framed E1.
· Optionally inserts a datalink in the E1 national use bits.
· Supports 4-bit codeword insertion in the E1 national use bits as specified in
ETS 300 233
· Supports transmission of the alarm indication signal (AIS) and the Yellow
alarm signal.
· Line side interface is the DS3 interface mutiplexed as per the G.747
recommendation.
· System side interface is either serial clock and data or H-MVIP
DS3 Receiver Section:
· Frames to a DS3 signal with a maximum average reframe time of less than
1.5 ms (as required by TR-TSY-000009 Section 4.1.2 and TR-TSY-000191
Section 5.2).
· Decodes a B3ZS-encoded signal and indicates line code violations. The
definition of line code violation is software selectable.
· Provides indication of M-frame boundaries from which M-subframe
boundaries and overhead bit positions in the DS3 stream can be determined
by external processing.
· Detects the DS3 alarm indication signal (AIS) and idle signal. Detection
algorithms operate correctly in the presence of a 10-3 bit error rate.
· Extracts valid X-bits and indicates far end receive failure (FERF).
· Accumulates up to 65,535 line code violation (LCV) events per second,
65,535 P-bit parity error events per second, 1023 F-bit or M-bit (framing bit)
events per second, 65,535 excessive zero (EXZ) events per second, and
when enabled for C-bit parity mode operation, up to 16,383 C-bit parity error
events per second, and 16,383 far end block error (FEBE) events per
second.
