1. Introduction
Functional Overview
The EdgeSync is a small form factor, highly accurate Multi-Sync Gateway that provides IEEE 1588-
2008 PTP Grand Master and Boundary Clock functionality. IEEE 1588-2008 PTP is also known as PTP
Version 2.
Figure 1 The EdgeSync
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).
EdgeSync will provide holdover depending on the chosen built-in oscillator.
Remote control and monitoring are provided over SSH, Web Interface and SNMP (v2, v3).
Interfaces
EdgeSync Interfaces are shown in following images, along with a brief description of them in the tables
below them. Detailed description of the interfaces is provided in the REF section of this User Guide

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].

Oscillator Options
EdgeSync:OCXO oscillator, 4-hour holdover for 1.5 µsec accuracy.
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. The variants are configured at the factory and cannot be
field upgraded at present. Section 10 of this User Guide presents the two variants available.
Components Block Diagram
The following block diagram defines the main components of the EdgeSync system along with the
physical connections to each component.
Figure 4 EdgeSync 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.

•User Interface and Control Plane Processor, which supports all the user access and connectivity
to the entire system. The Processor supports DHCP, HTTP webpage/CLI access, SSH, SFTP,
XML and SNMP (v2, v3).
•GNSS Receiver – GPS Receiver combined with either a Beidou or Glonass or Galileo Receiver
with external antenna input. The selection of the constellation is user configurable.
2. Installation
Before the EdgeSync is installed, review the information in this section. If difficulties are encountered
during the installation process, contact Orolia Customer Support, with the contact information
provided in the Contact Section of this User Guide.
Security Recommendations
The EdgeSync Management port and PTP Timing ports should be installed behind the company’s
firewall to prevent public access. Additionally, the PTP Timing ports should be connected to a Local
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.
Packaging List and Unpacking
The EdgeSync box contains the following:
•The EdgeSync Multi-Sync Gateway
•AC/DC power supply and spare terminal block connector
GNSS antenna and accessories, rack mounting bracket and secondary AC/DC power supplies are
available.
The EdgeSync is packaged to be protected from normal shock, vibration, and handling damage during
shipment. Unpack and inspect the box contents as follows:
1. Wear a properly grounded protective wrist strap or suitable ESD protection.
2. Inspect the shipping box for signs of damage. If the box appears to be damaged, notify both the
carrier, and Orolia or your Orolia distributor. Retain the shipping box and packaging material for
the carrier to inspect.
3. Open the box, being careful to cut only the packaging tape.
4. Locate and save the printed packaging list and paperwork that is included in the box.
5. Remove the EdgeSync from the box and place the unit on an anti-static surface.
6. Locate and set aside additional parts which may be contained in the box.

10 | EdgeSync Manual rev 1 orolia.com
7. Remove and dispose of the anti-static packaging from the EdgeSync and parts.
8. Verify that the model and serial number shown on the packaging list agrees with the model and
serial number on the EdgeSync. The model number can be found on a label affixed on the back
of EdgeSync. Contact Orolia or your Orolia distributor if the model or serial number do not
match.
Rack Mounting the EdgeSync
The EdgeSync is half of a 19-inch rack, and occupies 1.75 in (4.5 cm, 1RU) of vertical rack space. An
optional mounting bracket is available.
Warning: When rack mounting the EdgeSync, use the original mounting screws provided with the
mounting bracket so that the EdgeSync case will not be damaged. Do not substitute other mounting
screws.
Power and Ground Connections
Power
The EdgeSync uses two VDC power sources, primary and backup. One or both power sources can be
used. The power source can be 34 – 60 VDC. The VDC power connector uses two power feed lines,
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.
IMPORTANT NOTE:
All operation, test and performance references and specifications that Orolia, Inc. makes in its
EdgeSync customer documents, and on its label, and to certification authorities are based on actual
measurements ONLY when operated with the power supplies that Orolia provides or offers as an
optional accessory. If operated with other brands and/or different specifications of power supplies,
Orolia will NOT guarantee EdgeSync’s proper operation, functionality or its compliance with the stated
standards!
Ground
The EdgeSync ground is a 4 mm ground stud and is identified with the international ground marking as
shown on Figure
3 . This ground wire should be routed to earth ground.
Input / Output Signal Connections
Management
Using a standard CAT5 cable, connect the cable to the port labelled MGMT of the front panel to your
network. The data rate is 10/100 Base-T shielded RJ45 receptacle. The Management port supports
both forms of IP address assignment, static or DHCP.
