PM4325

• 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.
