Semiconductor Group
Frame alignment/synthesis for 2048 kbit/s (CEPT,
PCM 30) and 1544 kbit/s (T1, PCM 24)
Meets newest CCITT Rec’s (Blue Book), FTZ Rec’s and
AT&T technical advisories (DMI, August 1986)
Programmable formats for
PCM 30: Doubleframe, CRC Multiframe
PCM 24: 4-Frame Multiframe (F4), 12-Frame Multiframe
(F12, D3/4), Extended Superframe (ESF), Remote Switch
Mode (F72)
Selectable conditions for loss of sync
Selectable line codes (HDB3, B8ZS, AMI with ZCS)
Unipolar NRZ for interfacing fibre optical transmission
routes
Error checking via CRC4 or CRC6 procedures
Insertion and extraction of alarms and facility signaling
IDLE code insertion for selectable channels
System clock frequency of either 4096 kHz or 8192 kHz
Selectable 2048/4096 kbit/s system internal highway with programmable receive/transmit shifts
Two-frame deep elastic receive memory for receive route clock wander and jitter compensation
(can be reduced to one-frame length for PCM 30 master-slave applications)
One frame elastic transmit memory (PCM 24 mode only) for transmit route clock wander and
jitter compensation
Two different time-slot assignment procedures in PCM 24 mode
Support for different signaling schemes
Channel loop back capabilities
Channel parity error monitoring
Clear channel capabilities in PCM 24 mode
