BCS II Simplex Repeater User Manual

DS3 Input

Data Rate: 44.736 Mb/s + 100 ppm

Data Format: Bipolar with B3ZS coding

Jitter Tolerance: Meets requirements of Telcordia GR-499-CORE, Issue 1, December, 1995

Equalization: Selectable normal or high sensitivity receive equaliza- tion, based on receive cable length

DS3 Output

Data Rate: Same as input signal, transmit clock is recovered from in-

put signal. Under AOS condition (no valid input): 44.736 Mb/s + 100 ppm
