Announce receipt timeout

OMICRON
Use this field to specify the number of "Log Announce Interval" intervals
that have to pass without the receipt of an Announce message before an
ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES event occurs. See
"announceReceiptTimeout" in in IEEE 1588-2008.
Can only be changed for the PTP profiles Default P2P, Default E2E, and
Power (C37.238-2011):
- Default E2E and Default P2P: Value between 2 and 10
- Power (C37.238-2011): 2 or 3
For the PTP profiles Power (C37.238-2017) and Power utility
(61850-9-3:2016), this value is fixed.
Only available for PTP profiles Default E2E and Default P2P, and if
Transport is set to "UDP IPv6".
For UDP IPv6 transport, select the multicast scope that shall be used for
all PTP messages except peer delay mechanism messages. For more
detailed information, see IEEE 1588-2008, clause E.3, and IETF RFC
4921 (2006), section 2.7.
For peer delay mechanism messages the IPv6 multicast address
FF02::6B is used. For all other messages the IPv6 multicast address
FF0X::181 is used, where the value of X is selected by the IPv6
multicast scope setting.
All clocks in a network that shall be synchronized via PTP over
UDP IPv6 must use the same multicast scope setting. In
earlier versions of the OTMC 100 firmware this setting is not
available. The multicast scope is permanently set to "0x5: Site-
Local scope" on these devices. Configure your OTMC 100 to
"0x5: Site-Local scope" to allow synchronization to such
devices or update older devices with a new firmware image
(see section Running a software update for OTMC 100
page 28).
OTMC 100 allows configuration of the Differentiated Services Code
Point (DSCP, see RFC 2474) value of IPv4 and IPv6 PTP packets. Use
these fields to specify the DSCP value for PTP general messages and
PTP event messages. If your network does not use Differentiated
Services according to RFC 2474, use the default value (zero). Only
available for PTP profiles Default E2E and Default P2P, and if Transport
is set to "UDP IPv4" or "UDP IPv6".
