CX28394/28395/28398 Quad/x16/Octal—T1/E1/J1 Framers The CX28394/28395/28398 is a family of multiple framers for T1/E1/J1 and Integrated Service Digital Network (ISDN) primary rate interfaces operating at 1.544 Mbps or 2.048 Mbps. All framers are totally independent, and each combines a sophisticated framing synchronizer and transmit/receive slip buffers. Operations are controlled through a series of memory-mapped registers accessible via a parallel microprocessor port. Extensive register support is provided for alarm and error monitoring, signaling supervision (including ISDN D-channel/SS7 process), per-channel trunk conditioning, and Facility Data Link (FDL) maintenance. A flexible serial Time Division Multiplexed (TDM) system interface that supports bus rates from 1.536 to 8.
