CX28394/28395/28398

Quad/x16/Octal鈥擳1/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 8.192 MHz is featured.

Extensive test and diagnostic functions include a full set of loopbacks, Pseudo Random

Bit Sequence (PRBS) test pattern generation, Bit Error Rate (BER) meter, and forced

error insertion.
