7.4.2.1.2 PTP Instances

There are two types of PTP Instances used in a gPTP domain:

  1. PTP End Instance

  2. PTP Relay Instance

A PTP Instance operates in a single Bridge Component or End Station Component within exactly one gPTP domain. A UAFX Station can contain more than one PTP Instance in the same gPTP domain (see 7.4.2.1.4).
