Authentication and authorization in TLS PSK 128-bit or TLS PSK 256-bit occur as a single step,
based on the secret pre-shared key. Both ends of the link must be configured for the same key
size. Each unit will connect only to a remote unit that shares the same secret.

License keys and regulatory bands
The PTP 670 license key specifies the country of operation for the ODU, and lists the regulatory
bands that are licensed by regulators in that country. If a license key provides access to more
than one regulatory band, PTP 670 provides a choice between the available bands. In each
regulatory band, PTP 670 sets the following aspects of wireless operation to comply with the
applicable regulations:
•
Maximum transmit power
•
Radar avoidance
