  • G.8275.1 Telecom profile and PTP over Ethernet encapsulation support (ACX2100 and ACX2200)—Starting in Junos OS Release 21.2R1, ACX2100 and ACX2200 routers support Precision Time Protocol (PTP) over Ethernet encapsulation and G.8275.1 Telecom profile.

    The G.8275.1 Telecom profile supports the architecture defined in ITU-T G.8275 to enable the distribution of phase and time with full timing support. This profile requires all devices in the network to operate in combined or hybrid modes, which means that PTP and Synchronous Ethernet are enabled on all devices.

    PTP over Ethernet enables the effective implementation of packet-based technology that enables the operator to deliver synchronization services on packet-based mobile backhaul networks.
