This guide from Lawo, provides good material and guidance on how to setup PTP on your AES67 / ST2110-30 network

Some switches support PTP in order to increase clock accuracy. They can work in two modes: transparent and boundary clock.

For Clear-Com systems running IPT antennas for FreeSpeak II or FS Edge , a even tighter tolerance is required to allow for RF roaming
For good roaming IPT antennas require a tolerance of 100ns (± 0.1 µs)
The table below shows the values required for good FreeSpeak II / FS Edge roaming using IPT antennas
PTP parameters | Value (range) | Performance |
---|---|---|
Offset from the master clock (OFM) | ± 100 ns ± 0.1 µs | Excellent |
± 500 ns | Potential for roaming issues | |
± 1,000 ns ± 1 µs | Issues with roaming likely | |
>± 1,000 ns | Cannot roam between transceivers and intermittent loss-of-lock issues |
