3. Operation and equipment connection to the network is as any IEEE 1588 Ordinary
Clock.
4. Both Master and Slave operations are supported in endpoint mode. Ability to force
Slave or Master roles.
5. Encapsulations: PTP over UDP over IPv4 (IP Endpoint mode) as defined in IEEE
1588-2008 Annex D, PTP over IEEE 802.3 / Ethernet as defined in IEEE 1588-
2008 Annex F.
6. Compatible with unicast, multicast and hybrid transmission with UDP and Ethernet
payloads. Supports unicast negotiation.
7. Support of 1-step and 2-step clock modes both in slave or master emulation.
8. Support of peer-to-peer and end-to-end delay mechanisms.
9. Configuration of Domain, Priority 1, Priority 2 and Clock class. Configuration of
announced capabilities: UTC offset, time and frequency traceability, time-scale
and time source.
10. Setting of message rates for Sync, Delay Request, Peer Delay Request and
Announce messages. Configuration of Announce message time-out.
A.11.PHY Results
A.11.1. Cable Tests
1. For inactive links: Open/short fault indication and distance to fault in meters (accu-
racy: 1 m).
2. For 10/100 Mb/s active links, the following results are reported: current local port
MDI/MDI-X status.
3. For 1 Gb/s active links the following results are reported: current local port MDI/
MDI-X status, pair polarities (normal/inverted), pair skew (ns).
A.11.2. SFP
1. SFP presence, current interface, vendor, and part number.
2. Optical power measurement (transmitted and received power) over compatible
SFP transceivers.
A.11.3. Auto-Negotiation
1. Auto-negotiation results with current bit rate and duplex mode.
2. For 1000BASE-T indication of clock Master and Slave roles
A.11.4. Synchronous Ethernet
1. Measurement of the line frequency (MHz), frequency offset (ppm) and frequency
drift (ppm/s) as specified in ITU-T O.174 (11/2009) clause 10.
2. TIE / MTIE / TDEV measurement on Ethernet interfaces following ITU-T O.172
clause 10.
