Meinberg SyncBox PTPv2 - Manual (Page 6)

PTPv2 Slave with high accuracy Oscillator
The SyncBox provides a high precision time base (OCXO HQ) with multiple
outputs for 10MHz, PPS and IRIG via TCP/IP network, synchronized by a PTP
IEEE1588 grandmaster reference clock. The SyncBox act as a PTP slave with high
precision oscillator to produce different timing and frequency outputs. SyncBox is a
set of equipment composed of a PTP IEEE1588 Time Stamp Unit (TSU) and a power
supply, all installed in a metal DIN rail mounted chassis and ready to operate. Two
user configurable outputs for 1 PPS, 10 MHz and unmodulated time code (IRIG) can
be set up next to a modulated time code (IRIG) output. Also two capture inputs are
integrated to get high precision time stamps of external events. A simplified LINUX
operating system is installed on the single-board computers flash disk. After the
network connection has been established the timeserver can also be configured and
monitored remotely from a workstation via TELNET or SSH. An integrated HTTP
server enables access to the SyncBox by using an ordinary WEB browser.
The Modular System SyncBox
The SyncBox is a set of equipment composed of a PTP IEEE1588 Time Stamp
Unit (TSU) and a power supply unit, all installed in a metal rail mount case and ready
to operate. The interfaces provided by the SyncBox are accessible via connectors in
the front panel of the case. Details of the components are described below.
Front View SYNCBOX/AHS
SyncBox has one PTP IEEE1588 network interface. The outputs of the SyncBox
(10MHz, PPS and IRIG) will be enabled if the System has been synchronized by an
external PTP grandmaster once and the internal oscillator (OCXO HQ) has warmed
up. The SyncBox will start with a non valid time until it it synchronized by an
external PTP IEEE1588 gradmaster once. Next to PTP IEEE1588 a the Linux system
supports a number of further network protocols: HTTP(S), SSH and Telnet. Because
of this remote configuration or status requests can come from any WEB browser.
