Function
Bit Clock/S-Clock
TE-Mode:
Bit clock output, identical to IOM-2 data
rate (DCL/2).
LT-T Mode:
1.536 MHz output synchronous to S-
interface.
NT / LT-S Mode:
Bit clock output derived from the DCL
input clock divided by 2.
Data Downstream
IOM-2 data signal in downstream
direction.
Data Upstream
IOM-2 data signal in upstream direction.
Serial Data Strobe 1
Programmable strobe signal for time slot
and/or D-channel indication on IOM-2.
Serial Data Strobe 2
Programmable strobe signal for time slot
and/or D-channel indication on IOM-2.
