1Introduction
1.1 Functional Overview
The Ts2 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 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.
Outputs include IEEE 1588-2008 PTP, selectable FREQ Out, 1PPS, and Time of Day (ToD). Ts2 will provide
holdover depending on the chosen built-in oscillator.
Remote control and monitoring are provided over SSH, Web Interface and SNMP (v2, v3).
1.2 Interfaces
Ts2 Interfaces are shown in Figure 2 and Figure 3along 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.

1.3 Typical Applications
Ts2 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].
1.4 Oscillator Options
Standard: OCXO oscillator, 4-hour holdover for 1.5 µsec accuracy.
Superior: Super OCXO oscillator, 8-hour holdover for 1.5 µsec accuracy.
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. The variants are configured at the factory and cannot be field upgraded at present.
Contact information for ordering the Ts2 with the supportable slave capacities is presented in the
Contact Section of this User Guide on page 44. Section 8 of this User Guide presents all the variants
available.
1.6 Components Block Diagram
The following block diagram defines the main components of the Ts2 system along with the physical
connections to each component.

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.
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.
