Figure 34 G.8275.2 profile - additional configuration parameters 

 

G.8265.1 Telecom Profile 

This is yet another Telecom profile from ITU-T for providing frequency-only synchronization (or 

syntonization) over packet network. This was specified to support legacy TDM networks like 

(SONET/SDH, etc.). It does not provide time/phase synchronization.  

 

Figure 35 G.8265.1 PTP Profile 

Power version-1 profile 

This profile is specified for the power industry mainly in power system protection, control, automation, 

and data communication applications. This specific Power V1 is according to the IEEE C37.238-2011 

standard. It uses PTP over L2 multicast, P2P delay mechanism and one of the salient features of this 

profile is that it uses priority tagging for VLAN (i.e., VLAN-id = 0, priority = 4). 

In PTP::Clock page, additional configuration parameters are provided that are specific to Power Profile 

v1 as shown below.
