Configure TLV Settings
With the C37.238-2017 profile, neither the ATOI TLV or the C37.238 TLV are required on incoming traffic. The
ATOI TLV can be included in outgoing traffic using the 'ALTERNATIVE TIME OFFSET IN OUTGOING' setting,
and the C37.238 TLV is always included in outgoing traffic. The C37.238 TLV includes two configurable
settings — the C37.238 Grandmaster ID, and the C37.238 Network Time Inaccuracy.
GrandMaster ID
Set the C37.238 Grandmaster ID setting using the 'C37.238 GRANDMASTER ID' setting.
This is the “GMIdentity” (or “Grandmaster Identity”) as defined in C37.238-2017. Grandmaster Identity is
transmitted in IEEE_C37_238 TLV (2 bytes). The configurable range is 0 to 65,535. By default it is set to 3.
C37.238 Network Time Inaccuracy
Set the C37.238 Network Time Inaccuracy setting using the 'C37.238 NETWORK TIME INACCURACY''
setting.
This configurable field sets the “networkTimeInaccuracy” as defined in C37.238-2011. It will set the estimated
worst-case error in nanoseconds from the Grandmaster. The configurable range is 0 (default) to 2,147,483,647
ns.
