Time To Live (Packet
for Peer-to-Peer packets for which TTL is forced to 1 as specified in IEEE
Std 1588-2008 Annex D.3.
1PPS Offset: The 1PPS signal of this option card can be offset from the main
System 1PPS. This offset will be applied to all timestamps created by this
card. It can be set in 8ns increments. Range is -500 ms to +500 ms.
Priority 1: See IEEE 1588-2008, Section 8.10.1, 8.10.2.
Priority 2: See IEEE 1588-2008, Section 8.10.1, 8.10.2.
Enable SyncE: If checked, allows access to the synchronous Ethernet set-
tings. There will always be an ESMC message broadcast if Enable SyncE is
checked.
Note: For full functionality, SyncE requires Fiber Optic
SFP modules. Standard RJ45/ 1000BASE-T modules are gen-
erally not compatible with SyncE.
Enable ESMC: [checkbox]

ESMC message. One of two messages will be broadcast: either
the message selected in the SSM Code dropdown or the QL_

its references.
Output Enabled in
