PTP Grandmaster Configuration

This guide briefly describes how to configure Falcon-MX/G and µFalcon-MX/G to operate as a

PTP Grandmaster in compliance with ITU-T G.8275.1, G.8275.2 and G.8265.1 profiles. To

properly source and propagate timing signal the µFalcon-MX/G must first be installed and

connected to a GNSS antenna (for details on antenna installation refer to Technical Note:

GPS/GNSS Antenna Installation Guidelines on www.fibrolan.com Resources webpage).

1Physical Description

2Configuration Steps

2.1 Initial Settings

Before starting with the Timing configuration ensure proper management access via web GUI.

Detailed information on system turnup can be found in the Falcon M class Getting Started quick

guide that can be found in www.fibrolan.com.

2.2 GPS/GNSS Signal

Additional prerequisite is to assure a proper satellite signal. To do that hit the GPS/GNSS port

on the front panel at the GUI home page. This will lead to the GPS/GNSS monitor screen.

Verify the GPS/GNSS module is locked on the incoming signal, no alarms are present and there

is good visibility of satellites in the sky.

2.3 Setting up the SyncCenter

•Hit the SyncCenter button at the GUI top right corner.

•In the SyncCeter page enable source 1 and set it to GPS, as shown below, then press the

Apply at the bottom of the page.

3PTP Configuration

3.1 G.8275.1 Profile

This Precision time protocol telecom profile is intended for phase/time synchronization with full

timing support network. This is an Ethernet multicast profile (layer 2 transport)

•Hit the PTP link from the left side menu: Configuration>Timing>PTP

•Create a new PTP Clock instance and set it to Masteronly type and G.8275.1 Profile.

•Follow the hyperlink of the instance number to the next configuration page.

•Enable the relevant physical interface by checking the checkboxes of the relevant ports.

Notes:

1. G.8275.1 profile default settings are:

•Transport layer: Ethernet

•PTP Domain number: 24

•Message frame rates:

oAnnounce: (-3) or 8/sec

oSync: (-4) or 16/sec

oDelay Response: (-4) or 16/sec

2. Message frame rates can be modified by pressing the “Ports Configuration” link if needed.

3. This profile uses Multicast transmission, packets will be sent on any enabled port, regardless

of whether there is a slave connected to it or not.

•Apply the configuration by pressing the Apply at the bottom of the page.

3.2 G.8275.2 Profile

This Precision time protocol telecom profile is intended for phase/time synchronization with

partial timing support network. This is an UDP/IP unicast profile (layer 3 transport)

•Hit the PTP link from the left side menu: Configuration>Timing>PTP

•Create a new PTP Clock instance and set it to Masteronly type and G.8275.2Profile.

•Follow the hyperlink of the instance number to the next configuration page.

•Enable the relevant physical interface by checking the checkboxes of the relevant ports.

Notes:

1. G.8275.2 profile default settings are:

•Transport layer: IPv4 Unicast

•PTP Domain number: 44

•Message frame rates:

oAnnounce: (-3) or 8/sec

oSync: (-7) or 128/sec

oDelay Response: (-7) or 128/sec

2. In unicast profiles message rates are requested by slave device in dedicated signaling

3. Maximum message rates can be enforced on the Grandmaster per port by pressing the

“Ports Configuration”.

•Apply the configuration by pressing the Apply at the bottom of the page.

3.3 G.8265.1 Profile

This Precision time protocol telecom profile is intended for frequency synchronization. This is

an UDP/IP unicast profile (layer 3 transport)

•Hit the PTP link from the left side menu: Configuration>Timing>PTP

•Create a new PTP Clock instance and set it to Masteronly type and G.8265.1Profile.

•Follow the hyperlink of the instance number to the next configuration page.

•Enable the relevant physical interface by checking the checkboxes of the relevant ports.

Notes:

1. G.8265.1 profile default settings are:

•Transport layer: IPv4 Unicast

•PTP Domain number: 4

•Message frame rates:

oAnnounce: (-3) or 8/sec

oSync: (-7) or 128/sec

oDelay Response: (-7) or 128/sec

2. In unicast profiles message rates are requested by slave device in dedicated signaling

3. Maximum message rates can be enforced on the Grandmaster per port by pressing the

“Ports Configuration”.

•Apply the configuration by pressing the Apply at the bottom of the page.

•Save the configuration by hitting the Save button at the GUI top left corner.

Notes:

1. All Ethernet ports (1-24 and 29-32 on Falcon, 1-8 on µFalcon models) support PTP and SyncE

simultaneously

2. Falcon-MX/G copper port (25-28) are management ports and do not support PTP nor SyncE.

3. Internal ports (33-37 on Falcon, 9-11 on µFalcon models) may be ignored.

4. The default parameters of the profile may be modified as needed (but take care to avoid

misconfiguration)

5. If needed PTP messages can be tagged by setting the port mode to Trunk

6. For more complex or atypical configurations, please Contact Us.
