OCTAL T1/E1/J1 Short Haul Line Interface Device
FEATURES
Monolithic device which integrates 8 T1/J1 or E1 short haul line interface circuits. Software-selectable 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, CTR4, CTR-12 and CTR-13. Provides encoding and decoding of B8ZS, HDB3 and AMI line codes. Provides clock recovery and line performance monitoring. Provides transmit and receive jitter attenuation. Provides support for redundancy. 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. Provides an 8-bit microprocessor bus interface for configuration, control, and status monitoring. Provides line and digital loopback modes. Supports programmable inband loopback codes. Uses line rate system clock. Provides an IEEE 1149.1 (JTAG) compliant test access port (TAP) and controller for boundary scan test. Provides a microprocessor-readable general purpose input pin and a microprocessor-writable general purpose output pin.
