PTP packets payload on the network, where: The transmissions initiated by the Master
(Announce, Sync/Follow-Up) run in Multicast mode.
The transmissions initiated by the Slaves (Delay_Req/Delay_Resp) run in Unicast mode.
Multicast
cast Sync and Announce messages to the Multicast address (as long as it is
the Best Master on the network). Deactivating this option will remove the
messages. When the PTP module is set in multicast mode, this will deny the
requests from the Slaves Clocks to running in unicast mode.
Checking this box will cause two additional fields to display that will
allow you to configure the:
Multicast
respond to multicast Delay Requests (as long as it is the Best Master on the
network). Deactivating this option will prevent the Master from responding
to these.
Unicast

Unicast Auto-Negotiation process. This setting is always enabled.

The Telecom profile uses different clock class values than the default profile. It uses clock classes in the
range from 80 to 110, and these values map to the SSM Quality level that is broadcast in the ESMC message,
as defined in Section 6.7.3.1 of G8265.1. If the user enables Sync-E, and broadcasting of the ESMC message,
the parameter that controls which SSM quality level is broadcast when the unit is in sync is user-accessible.
This will appear both in the ESMC message, and in the Clock Class (if the "Clock Class Set" is set to ITU). It is
also possible to control whether the ESMC message chosen degrades to QL-DNU when out of sync.
