1. DETAILED DESCRIPTION
The DS3150 performs all the functions necessary for interfacing at the physical layer to DS3, E3, and
STS-1 lines. The device has independent receive and transmit paths and a built-in jitter attenuator
(Figure
inversion (AMI) signal and monitors for loss-of-signal. The receiver optionally performs B3ZS/HDB3
decoding and outputs the recovered data in either NRZ or bipolar format. The transmitter accepts data in
either NRZ or bipolar format, optionally performs B3ZS/HDB3 encoding, and drives standards-compliant
waveforms onto the outgoing 75Ω coaxial cable. The jitter attenuator can be mapped into the receiver
data path, mapped into the transmitter data path, or disabled. The DS3150 conforms to the
telecommunication standards listed in
proper operation.
