TWELVE CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCHRONIZER
REV. 1.0.3
FEATURES
RECEIVER
R3
Technology
(Reconfigurable,
Relayless
Redundancy)
On chip Clock and Data Recovery circuit for high
input jitter tolerance
Meets E3/DS3/STS-1 Jitter Tolerance Requirement
Detects and Clears LOS as per G.775
Receiver Monitor mode handles up to 20 dB flat
loss with 6 dB cable attenuation
On chip B3ZS/HDB3 encoder and decoder that can
be either enabled or disabled
On-chip clock synthesizer provides the appropriate
rate clock from a single 12.288 MHz Clock
Provides low jitter output clock
TRANSMITTER
R3
Technology
(Reconfigurable,
Relayless
Redundancy)
Compliant with Bellcore GR-499, GR-253 and ANSI
T1.102 Specification for transmit pulse
Tri-state Transmit output capability for redundancy
applications
Each Transmitter can be independently turned on
or off
