Grand Master and Boundary Clock functionality. IEEE 1588-2008 PTP is also known as PTP Version 2. Figure 1 The Ts2 Ts2 gets its time from the built-in GNSS receiver or 1PPS/ToD input or IEEE 1588-2008 PTP as input references. PTP algorithms are leveraged to deliver stringent timing for frequency and phase profiles.
Page 9: Typical Applications
1.5 PTP Slave Capacity The Ts2 has variants that can support different unicast slave capacity (32, 128, 256, ..) slaves at up to 128 sync / delay packets per second when the MCE is operated as a master clock depending on the product SKU.
Page 10: Figure 4 Ts2 Components Block Diagram
Qg 2 Multi-Sync Gateway User Guide Introduction Figure 4 Ts2 Components Block Diagram  Managed Clock Engine (MCE) is a full packet network-based synchronization engine supporting IEEE 1588-2008 Precise Time Protocol. The MCE is where IEEE 1588-2008 PTP packet communication processing runs, and port / BNC provisioning is applied. GNSS signals and User Interface Processor (UIP) commands are sent to the MCE.

Page 26: Safety Considerations
 When installing or working on the Ts2 equipment, ESD wrist straps should be worn.  Use the specified power supply and ground for the Ts2 equipment as stated in the Power and Ground Connections section.  Refer to the Applying Power section when applying power to the Ts2 equipment.
Page 27: Managed Clock Engine Overview
PRC_DEGRADATION_B (187) or APP_DEGRADATION_B (193), so clock can potentially become a PTP slave if a better clock appears on the network. This mode means that the Ts2 clock has the GNSS-signal as its primary source of synchronization and the PTP as a backup source, i.e. when no GNSS-signal present.
Page 28: Gnss Interface
UNKNOWN/ERROR 6.3.1 FREE RUNNING State The Ts2 clock comes into this state upon initialization. The Ts2 clock time is not set, the clock class is DEFAULT (248), clock accuracy is UNKNOWN (0xFE). The timescale is PTP, the UTC offset is initially set to 37 secs, leap flags are FALSE. In Free Running state, the clock frequency comes from the on-board oscillator.
Page 29: Unicast Operations
(if valid) and leap flags are also set to master’s values and the time source is set to PTP. 6.3.4 HOLDOVER State The Ts2 clock enters this state when the synchronization source is lost. If the clock was synchronized with PTP master its clock class remains unchanged. Otherwise the clock class is modified according the engine’s operational mode and the clock accuracy is changed based on the time spent in the holdover...
Page 30: Gateway And Boundary Clock
6.5 Gateway and Boundary clock The Ts2 Multi-Sync Gateway has the capability of using both of its Ethernet ports (Port 1 and Port 2) as PTP ports. This opens the possibility of using the Ts2 as a two-port gateway or boundary clock. For more information about Gateway and Boundary Clocks, see [1].
Page 31: Ptp Servo Configuration Parameters
Qg 2 Multi-Sync Gateway User Guide Managed Clock Engine Overview Another capability of the Ts2 is for both ports to be configured as master ports. In that configuration, each port would have its own IP address and be associated with different subnets. However, both ports would have the same PTP Clock Identity.
Page 32: Synchronous Ethernet (Synce)
(e.g. 300 sec) would be a better setting. A longer time constant requires a more stable oscillator to be effective. For example, a time constant above 500 sec requires the Ts2 super OCXO. The default value is 100 sec.
Page 33: Figure 17 Synce Off
Figure 18 SyncE in Master Mode In this mode of operation, Ts2 is in GNSS-only operating mode where it gets 1pps and ToD signals from a GNSS receiver (internal or external to Ts2), which was originally extracted from GNSS L1 signal . In this mode, the frequency, phase and time references are extracted from GNSS signal, and SyncE is output on SJC-DEV7250-HR Rev.

PTP-aware and participates in the PTP protocol. When Ts2 is put in Boundary Clock mode in this network, the input SyncE from upstream is used as frequency reference and used directly for SyncE distribution on downstream port.

Figure 22 SyncE in BC mode for G8275.2, ref input on Port-2 6.7.6 SyncE – additional notes Some additional notes regarding SyncE feature in Ts2: 1. Synchronous Ethernet is supported only for 1GE interface speed. If user had configured previously on Interfaces::PTP webpage for a different Auto-Negotiation and speed parameters, they will be reset to 1000Mbps Full-duplex.

When Hard Reset Button is pushed and held for a longer duration (approx. 10 seconds), it will do a factory reset of the unit followed by a reboot. The current configuration of Ts2 will NOT be preserved and the user should save and restore their configuration as needed.

FiberStore (FS): H3C SFP-10GSR-85 (SFP+ dual-rate configured for 1GE) NOTE: SFP Copper modules are also available and will work with Ts2. The user should be aware that in that case, the PHY is inside the SFP Copper and in most cases will not fully support Synchronous Ethernet feature.
