Description

When sharing AoIP amongst different products, having a common time base is not only desirable, it's critical. In a mixed system, you might have several different time requirements. For example, some Axia devices will still require a Livewire Clock. Wheatnet systems will require a Wheatnet clock. Dante devices use IEEE1588 clocks (PTPv1) and AES67 devices use IEEE1588-2008 (PTPv2)

Something has to lock all of these clocks so they share a common time base.


Confirming Proper Clock

We'll use Dante Controller in this example. Controller for your product may differ or be integrated with software from your manufacturer.
  1. Open Dante Controller and allow it to complete the discovery process.
  2. Click on the Clock Status tab

Note that one of our devices (the AVIOUSB device) is the Leader for the v1 clock. All of your other Dante devices should show Passive for v1.

If you have a proper PTPv2 clock, then all of your devices will show Follower for v2.

Having a single Dante device as Leader for v1, and a Follower to v2, means that we now have our AES67 PTPv2 clock being the source for the Dante v1 clocks, thereby locking those to clocks together.
