EdgeSync Figure 1 The EdgeSync 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. Outputs include IEEE 1588-2008 PTP, selectable FREQ Out, 1PPS, and Time of Day (ToD).
Table 1 EdgeSync Rear Panel Interfaces Typical Applications EdgeSync is a small form factor IEEE-1588-2008 PTP Edge Grand Master and Boundary Clock that can be used for smart grid transmission and distribution substations. This Multi-Sync Gateway platform is designed for small cell clusters, C-RAN, and edge applications. For more information about PTP, see [1].
EdgeSync+: HP OCXO oscillator, 8-hour holdover for 1.5 µsec accuracy. PTP Slave Capacity The EdgeSync has two variants that can support different unicast slave capacity (32 or 128) slaves at up to 128 sync / delay packets per second when the Managed Clock Engine (MCE) is operated as a master clock depending on the product SKU.
Area Network (LAN) or Wide Area Network (WAN) dedicated to transporting PTP timing messages. Environmental Requirements The EdgeSync operating temperature is 0°C to 50° C (-32°F to 122° F). Use only shielded cable for all signal wiring, including I/O, clocks and Ethernet. Use the Ground connector to appropriately ground the EdgeSync to earth ground.
PWR A and PWR B. EdgeSync comes equipped with 2 Phoenix connectors to supply PWR A and PWR B and the user needs to connect the two terminals of it to their DC +/- supplies. The EdgeSync can also be powered by two VAC power sources, with 28 – 40 VAC supply.
Console A mini-USB connector labelled Console is available for EdgeSync to have a serial connection to a PC or laptop. The user can connect to EdgeSync console via terminal emulation applications on PC like Tera Term, PuTTy, minicom or Procomm to access the CLI over the serial port.
Logging in with the console Log into EdgeSync using the mini-USB console. Default set-up is 115200 baud, 8 bits, no parity, and one stop bit. Login is admin and password are admin. Terminal emulation software like Tera Term, PuTTY, minicom and Procomm can be used for this purpose.
Web Interface This chapter deals with the Web Interface of EdgeSync. A topic for each page in the web interface is provided, with an explanation of each tab, button and selection on each page. The Login Webpage and Home Webpage are presented as a starting point for accessing the Web Interface.

The following safety consideration should be used when handling and installing the EdgeSync. • When installing or working on the EdgeSync equipment, ESD wrist straps should be worn. Use the specified power supply and ground for the EdgeSync equipment as stated in the Power • and Ground Connections section.
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 EdgeSync 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.
ToD-input signal and the clock become a PTP master. When the EdgeSync engine is running in GNSS Only mode or PTP Only mode, the clock class is automatically changed to either PRC_SYNC (6) or APP_SYNC (13) and the clock accuracy is set to WITHIN_100_NS.
After holdover interval expires, the clock switches to the FREE RUNNING state, and its accuracy is reset to UNKNOWN (0xFE). UNKNOWN/ERROR State The EdgeSync clock has entered a failed or error condition and the sync state is unknown. Unicast Operations By default, unicast operations are disabled and the EdgeSync port operates in multicast mode. After unicast mode is enabled no multicast communications are possible.
Unicast BOTH mode of operation The PTP port on EdgeSync can be configured to automatically assume either the role of a unicast Master or a unicast Slave when the port mode is unicast BOTH. For example, if a port is in unicast Master mode and has GNSS reference and if the GNSS reference is lost, it can switch over to unicast Slave to another GM in the network.
The EdgeSync 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 EdgeSync as a two-port gateway or boundary clock. For more information about Gateway and Boundary Clocks, see [1].
PTP messages from an external Grand Master (GM) Clock. The PTP Clock Webpage is used to set the EdgeSync clock as a boundary clock, described in PTP :: Clock Section of this User Guide. The following figure illustrates the difference between a Gateway Clock and a Boundary Clock. The slaves connected to a Gateway Clock will only recognize the Gateway Clock as a Grand Master and not any other upstream masters.

Frequency Out The syntonized frequency that will be output on the FREQ Out port on the EdgeSync Front Panel. The valid options are 10MHz (default), 1.54MHz (T1 frequency) and 2.048 (E1 frequency). SNTP Besides PTP timing protocol, EdgeSync supports SNTP (Simple Network Time Protocol) for those applications where very high precision (i.e., sub-microsecond accuracy) synchronization is not a...
SNTP server. EdgeSync can operate as a PTP grandmaster or as a NTP Stratum-1 server, by getting time reference from GNSS and distributing that over the network to PTP slaves or NTP clients. If SNTP is enabled, then EdgeSync can service both, PTP slaves as well as NTP clients.
EdgeSync provides the flexibility and ease for customers to select one of the many PTP profiles provided to set the EdgeSync timing engine mode of operation. In the current release, both ports will be set to the same profile and not independently.
With EdgeSync, the user can select one of these PTP profiles for the timing engine to operate in. To make it user friendly, once the profile is selected, internally EdgeSync software will set up the most of the PTP profile specific parameters to default values for that profile and it is up to the customer if they want to customize it further (like a power user).

Synchronization Messaging Channel (ESMC). This ESMC message is to convey the reference clock quality and traceability information in the form of Quality Level (QL).

SyncE feature can be deployed as described below. The PHY’s used in EdgeSync support SyncE in terms of supporting clock recovery on Ethernet Rx and being able to provide 125MHz clock externally for Ethernet Tx. This is supported with native RJ45 (1000BASE-T) PTP port interfaces and with optical 1GE SFP modules.
In this mode of operation, EdgeSync is in GNSS-only operating mode where it gets 1pps and ToD signals from a GNSS receiver (internal or external to EdgeSync), 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 both ports for frequency with ESMC/QL message distribution to next downstream L2 network node.

Open RAN, ORAN deployment scenarios EdgeSync is a simple yet powerful and flexible stand-alone timing and synchronization solution for todays and next generation networks. Specifically with the advent of commercial off the shelf hardware (COTS), open-source software and disaggregation concepts and technologies into Radio Access Network (RAN).
Regardless of whether the network operator deploys a disaggregated multi-vendor or the legacy single-vendor infrastructure, precise timing and synchronization is critical. Shown below is how EdgeSync can be deployed for the different configurations as specified in Synchronization plane (or S-plane) of ORAN Workgroup-4. The configurations are specified as LLS-C1 through LLS-C4, where LLS = low-level split.

RJ45 ports. These ports have been designed for standard SFP 1GE modules and dual-rate SFP+ modules operating at 1GE speed. Orolia has verified the operation with modules from leading vendors as shown below: Finisar: FTRJ8519P1BNL, FCLF-8521-3, FTLF1318P3BTL (available from Orolia as SFP-FIBER-SM)
FiberStore (FS): H3C SFP-10GSR-85 (SFP+ dual-rate configured for 1GE) NOTE: SFP Copper modules are also available and will work with EdgeSync. 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.
