Arguments
This command requires the following argument(s):
Timing Reference
Priorities
Enter the timing reference priority. The clock reference with the
highest priority is used to lock the timing. In case of failure, the next
highest priority source is used. The valid range is 4 to 0 (4 = highest, 1
= lowest, 0 = disabled).
External Reference Type
Enter the external reference type. This refers to the type of signal
present used for the external references. It can be either DS1 or E1.
Note:
These are standard communication terms.
ODS1 Framing Type
Enter the framing type. This option is based on the type selected for
the external reference type.
DS1--> Can be either SF (superframe) or ESF (extended
superframe).
E1 --> framing or no framing.
Wait Time to Restore
When a higher priority clock reference returns, this is the time to wait
before restoring this clock source as the current reference. This wait
time ensures the source is stable before using it as the clock source.
OCN Port/Line TMG
References
The Primary and Secondary OC-N references are selected from any of
the 32 ports on the Cajun A500.
