PM4325 OCTLIU ST Octal Short Haul T1/E1/J1 Low Latency Transport Line Interface FEATURES • 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. • 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. • 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 bipolar DS-1 signal and HDB3 or AMI decoding when processing a bipolar E1 signal. • Detects line code violations (LCVs), B8ZS/HDB3 line code signatures, and four (E1), eight (T1+B8ZS), or sixteen (T1 AMI) successive zeros. • Provides a programmable depth FIFO buffer for jitter attenuation, rate conversion, and latency optimization in the receive path. SYSTEM INTERFACE • Supports transfer of transmitted single rail PCM and signaling data from 1.544 Mbit/s and 2.048 Mbit/s backplane buses or a SBI/SBI TR interface for low pin count interconnection of up to 11 OCTLIU STs to the high-density PM5366 TEMAP 84 T1/E1 framer. RECEIVE SECTION • Supports T1/E1 signal reception for distances with up to 12dB of cable attenuation at nominal conditions using PIC 22 gauge cable emulation. • Supports G.772 compliant non-intrusive protected monitoring points. TRANSMIT SECTION • Generates DSX-1 short haul pulses with programmable pulse shape compatible with AT&T, ANSI, and ITU requirements.
