| Features, Applications |
The 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 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. 16 T1/E1/J1 Framers in one package Extensive support of various protocols T1: SF, ESF, SLC�96, T1DM, TTC G.706, G.732, ISDN primary rate (ETS300 011, INS 500) Extracts and inserts signaling bits Dual HDLC controllers per framer for data link and LAPD/SS7 signaling Two-frame transmit and receive PCM slip buffers Separate or multiplexed system bus interfaces Parallel 8-bit microprocessor port supports Intel or Motorola buses BERT generation and counting B8ZS/HDB3/Bit 7 zero suppression (CX28394 and CX28398 only) Operates from a single +3.3 Vdc � 5% power supply Low-power CMOS technology Receive Dual Rail or NRZ RX Slip Buffer Receive System BusApplications Multiline T1/E1 Channel Service Unit/Data Service Unit (CSU/DSU) Digital Access Cross-Connect System (DACS) T1/E1 Multiplexer (MUX) PBXs and PCM channel bank ISDN Primary Rate Access (PRA) Frame Relay Switches and Access Devices (FRADS) SONET/SDH add/drop multiplexers T3/E3 channelized access concentrators All Rights Reserved.
