TRANSMIT INTERFACE CHARACTERISTICS
Accepts either Single-Rail or Dual-Rail data from
Terminal Equipment and generates a bipolar signal
Integrated Pulse Shaping Circuit
Built-in B3ZS/HDB3 Encoder (which can be dis-
abled)
Contains Transmit Clock Duty Cycle Correction Cir-
cuit on-chip
Generates pulses that comply with the ITU-T G.703
pulse template (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) and Timing Recovery
Declares and Clears the LOS alarm 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 dis-
abled)
Recovered Data can be automatically muted while
the LOS Condition is declared
Outputs either Single-Rail or Dual-Rail data to the
Terminal Equipment
Receiver can be powered down in order to con-
serve power in redundancy designs
