Priority 2: See IEEE 1588-2008, Section 8.10.1, 8.10.2.
Enable SyncE : If checked, allows access to the synchronous Ethernet settings.
There will always be an ESMC message broadcast if Enable SyncE is checked.
Note: For full functionality, SyncE requires Fiber Optic SFPmodules.
Standard RJ45/ 1000BASE-T modules are generally not compatible
with SyncE.
Enable ESMC: [checkbox]
ESMC Signal Control: Determines which SSM to use in the ESMC
message. One of two messages will be broadcast: either the message
selected in the SSM Code dropdown or the QL_DNU code. The user
may set one of the following broadcasting options:
Output Always Enabled: Always broadcasts the selected SSM
code, even when SecureSync is not synchronized to its ref-
erences.
Output Enabled in Holdover: The output uses the selected
SSM code unless SecureSync is not synchronized to its ref-
erences (the output is present while in the Holdover mode).
While SecureSync is not synchronized, QL-DNU SSM code will
be broadcast.
Output Disabled in Holdover: The output uses the selected
SSM code unless the SecureSync references are considered not
qualified and invalid (the output is not present while in the Hol-
dover mode). While references are invalid, QL-DNU SSM code
will be broadcast.
Output Always Disabled: The output is not present, even if any
SecureSync references are present and considered qualified.
QL-DNU SSM code is broadcast.
SSM Code : The Sync Status Messaging (SSM) code to be used.
Choice of code is made through the drop-down list.
