Protocol model

Ethernet bridging behavior at each end of the wireless link is equivalent to a three-
port, managed, transparent MAC bridge where the three ports are:
x
Ethernet Management Port
x
Ethernet Data Port
x
Wireless Port
Frames are transmitted at the Wireless port over a proprietary point-to-point
circuit-mode link layer between ends of the PTP 800 link. Ethernet frames received
at the data or management ports, or generated internally within the management
agent, are encapsulated within a lightweight MAC layer for transmission over the
wireless link.
In out-of-band local mode
management network (shown in red) is isolated from the customer data network
(shown in blue). In out-of-band mode, the management network is isolated from the
customer data at the wireless port by use of a separate service access point and
associated dedicated logical channel. Ethernet frames will not leak between
management and data networks, even in the presence of configuration errors.
