PM4344 Features

• Monolithic single-chip device that integrates four full-featured T1 framers and transmitters for terminating duplex DS1 signals.
• Supports SF, ESF, T1DM (DDS), and SLC®96 format DS1 signals.
• Supports unframed mode. Supports B8ZS or AMI line codes.
• Supports transfer of PCM and signalling data to/from 1.544 Mbit/s, 2.048 Mbit/s, 12.352 Mbit/s, or 16.384 Mbit/s backplane buses.
• Supports n x DS0 backplane interface for fractional T1.
• Provides robbed-bit signalling extraction/insertion, programmable idle and digital milliwatt code substitution, and two superframes of signalling debounce on a per-channel basis.
• Provides trunk conditioning which forces programmable trouble code substitution and signalling conditioning on all/selected channels.
• Provides ESF bit-oriented code detection/generation, and an HDLC interface for terminating/generating the ESF data link.
• Software and functionally compatible with the PM4341A T1XC Single T1 Transceiver. Pin-compatible with the PM6344 EQUAD Quad E1 Framer.
• Provides an 8-bit microprocessor bus interface for configuration, control, and status monitoring.
• Low power 5 V CMOS technology.
• Available in a rectangular 128-pin PQFP (14 by 20 mm) package.
