THREE CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCRONIZER
REV. 1.0.4
TRANSMIT INTERFACE CHARACTERISTICS
Accepts either Single-Rail or Dual-Rail data from Terminal Equipment and generates a bipolar signal to the
line
Integrated Pulse Shaping Circuit
Built-in B3ZS/HDB3 Encoder (which can be disabled)
Accepts Transmit Clock with duty cycle of 30%-70%
Generates pulses that comply with the ITU-T G.703 pulse template for E3 applications
Generates pulses that comply with the DSX-3 pulse template, as specified in Bellcore GR-499-CORE and
ANSI T1.102_1993
Generates pulses that comply with the STSX-1 pulse template, as specified in Bellcore GR-253-CORE
Transmitter can be turned off in order to support redundancy designs
RECEIVE INTERFACE CHARACTERISTICS
Integrated Adaptive Receive Equalization (optional) for optimal Clock and Data Recovery
Declares and Clears the LOS defect per ITU-T G.775 requirements for E3 and DS3 applications
Meets Jitter Tolerance Requirements, as specified in ITU-T G.823_1993 for E3 Applications
Meets Jitter Tolerance Requirements, as specified in Bellcore GR-499-CORE for DS3 Applications
Declares Loss of Signal (LOS) and Loss of Lock (LOL) Alarms
Built-in B3ZS/HDB3 Decoder (which can be disabled)
Recovered Data can be muted while the LOS Condition is declared
Outputs either Single-Rail or Dual-Rail data to the Terminal Equipment
