Transmit external Overhead
bits input. The Overhead bit
groups to be inserted through
this pin are programmable.
The options for each mode of
operation are specified in
Section 2.1.1
Used to indicate to the system
when to insert a new
Overhead bit on TEXT pin.
This output has a clock pulse
for each position of Overhead
bits (for the specific DS3/E3
mode) that were chosen to be
inserted through TEXT pin. Its
behavior is specified in
