1 Features

Serial Interface to Line Interface Unit

q Frame alignment/synthesis for 2048 kbit/s (CEPT,

PCM 30) and 1544 kbit/s (T1, PCM 24)

q Meets newest CCITT Rec’s (Blue Book), FTZ Rec’s and

AT&T technical advisories (DMI, August 1986)

q 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)

q Selectable conditions for loss of sync

q Selectable line codes (HDB3, B8ZS, AMI with ZCS)

q Unipolar NRZ for interfacing fibre optical transmission

routes

q Error checking via CRC4 or CRC6 procedures

q Insertion and extraction of alarms and facility signaling

P-LCC-44

Serial Interface to System Internal Highway

P-DIP-40

q System clock frequency of either 4096 kHz or 8192 kHz

q Selectable 2048/4096 kbit/s system internal highway with programmable receive/transmit shifts

q 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)

q One frame elastic transmit memory (PCM 24 mode only) for transmit route clock wander and

jitter compensation

q Two different time-slot assignment procedures in PCM 24 mode

q Support for different signaling schemes

q Channel loop back capabilities

q Channel parity error monitoring

q Clear channel capabilities in PCM 24 mode
