Livewire+ AES67
Livewire+ is Telos Alliance's low-latency audio-over-IP platform for broadcast facilities. It carries uncompressed audio, control, GPIO, and program-associated data and includes AES67 interoperability, while native Livewire discovery and control remain part of the Livewire ecosystem.

Gotchas & IT Notes
- ⚠Do not apply every Telos product port to every endpoint. Native Livewire clock/advertisement services differ from AES67.
- ⚠Other Livewire products may use additional legacy clock and control services; scope the selected product and firmware.
