Summary Information
E1 TRANSCEIVER FEATURES
Monolithic single chip device which integrates a full-featured E1 framer with on-chip analog line interface. Provides frame synchronization and frame generation for a G.704/G.706 2.048 Mbit/s signal with capability to support the optional signalling and CRC multiframes. Supports HDB3 or AMI line coding and accepts gapped data streams to support higher rate demultiplexing. Supports both 75 Ohm and 120 Ohm G.703 line interfaces. Provides Channel Associated Signalling extraction/insertion, programmable idle code substitution, digital milliwatt code substitution, data inversion and up to 3 multiframes of signalling debounce on a per channel basis. Optionally extracts/inserts the datalink from/to timeslot 16 to receive/transmit Common Channel Signalling. Pin compatible with the PM4341A T1XC T1 Transceiver. Software compatible with the PM6344 EQUAD E1 Framer, and PM6388 EOCTL E1 Framer. Provides an 8-bit microprocessor bus interface for configuration, control and status monitoring. Low-power 5V CMOS technology. Available in a high density 80-pin (14 by 14mm) PQFP or in a 68-pin PLCC package.
