Description
The External Clock Output
Timeslot parameter is used
to set the output timeslot for
the S1 byte of the external
clock source. The external
clock source transmits the S1
overhead byte through
certain timeslots. After
starting the SSM protocol,
make sure that the timeslot
for receiving the S1 byte is
consistent with the timeslot
for transmitting the S1 byte
so that the S1 byte can be
received correctly.

detailed information.
The External Source
Output Threshold
parameter is used to set the
output quality threshold of
the external clock source.
When the output quality of
the external clock source is
inferior to the threshold, the
action specified for 2M
phase-locked source failure
is invoked to control the
external clock source output.
