PTP page
eth window groups
The following fields apply to both eth window groups. The single-channel encoder will only have one eth window
group.
Configuration and Management Interfaces
Interface
Displays the Ethernet interface associated with the PTP settings.
Domain Number
Enter the domain number in this field. Valid entries are 0 through 127.
Priority 1
Enter the priority number in this field.
Priority 2
Enter the priority number in this field.
IMPORTANT: If a new device is added to the network and the GM changes, a brief outage will
be experienced while all connected devices synchronize with the new clock. Because of this,
Atlona recommends that one unit gets manually defined as the GM and have both Priority 1
and Priority 2 fields be set to 1.
The PTP page provides options for adjust Precision Time Protocol (PTP) for AES67 audio streams. PTP is used by
AES67 to keep all audio streams synchronized.
For a system utilizing PTP, all devices undergo an automatic self-election process to choose the device to be used as
the PTP grandmaster (GM) clock, based on the accuracy of the device’s clock and the device’s configured priority.
A lower priority number means the device is more likely to get selected as the GM. OmniStream runs 1 PTP daemon
per Ethernet interface.
