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.
• TE-Mode:
Auxiliary Port 0 - 2 (input/output)
These pins are individually programmable as
general input/output. The state of the pin can be
read from (input) / written to (output) a register.
• LT-T/LT-S/NT Mode:
CH0-2 - IOM-2 Channel Select (input)
These pins select one of eight channels on the IOM-
2 interface.
Auxiliary Port 3 (input/output)
This pin is programmable as general input/output.
The state of the pin can be read from (input) / written
to (output) a register.
