- Provides per receiver, clock recovery, and line performance monitoring.
- Provides transmit and receive jitter attenuation.
- Provides support for redundancy.
- Provides a digitally programmable Shorthaul pulse template per transmitter.
- 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.
