HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
Sꢀ 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.
Sꢀ Optionally inserts a datalink in the E1 national use bits.
Sꢀ Supports 4-bit codeword insertion in the E1 national use bits as specified in
ETS 300 233
Sꢀ Supports transmission of the alarm indication signal (AIS) and the Yellow
alarm signal.
Sꢀ Line side interface is the DS3 interface mutiplexed as per the G.747
recommendation.
Sꢀ System side interface is either serial clock and data or H-MVIP
DS3 Receiver Section:
Sꢀ 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).
Sꢀ Decodes a B3ZS-encoded signal and indicates line code violations. The
definition of line code violation is software selectable.
Sꢀ 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.
Sꢀ Detects the DS3 alarm indication signal (AIS) and idle signal. Detection
-3
algorithms operate correctly in the presence of a 10 bit error rate.
Sꢀ Extracts valid X-bits and indicates far end receive failure (FERF).
Sꢀ 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.
