PM4325 www.DataSheet4U.com OCTLIU ST Octal Short Haul T1/E1/J1 Low Latency Transport Line Interface FEATURES Monolithic device integrating eight T1/J1 or E1 short haul line interface units. Software switchable between T1/J1 and E1 operation on a per-device basis. Meets or exceeds T1/J1 and E1 short haul network access specifications including ANSI T1.102, T1.403, T1.408, AT&T TR 62411, ITU-T G.703, G.704 as well as ETSI 300-011, TBR 4, TBR 12, and TBR 13. In conjunction with the TEMAP 84 (PM5366), allows Add Drop Multiplexers and Terminal Multiplexers to meet GR253, GR496, and G.783. Optional encoding/decoding of B8ZS, HDB3, and AMI line codes. Provides receive equalization, clock recovery, and line performance monitoring. Provides transmit and receive jitter attenuation. Provides digitally programmable pulse templates. Provides a selectable, per channel independent de-jittered T1 or E1 recovered clock for system timing and redundancy. Provides PRBS generators and detectors on each tributary for error testing at DS1 and E1 rates as recommended in ITU-T O.151. Uses line rate system clock. Recovers clock and data using a digital phase locked loop for high jitter tolerance. Tolerates more than 0.4 UI peak-topeak high frequency jitter as required by AT&T TR 62411 and Bellcore TR-TSY-000170. Outputs dual rail recovered line pulses, a single rail DS-1/E1 signal, or parallel data in SBI/SBI TR bus format. Performs B8ZS or AMI decoding when processing a bi...
