Is the PTP 600 Series an 802.11a device? No, although similar, the PTP 600 Series
uses different encoding and radio transmission systems from 802.11a. In areas where
802.11a systems are operating, the PTP 600 Series will detect the 802.11a radio
signals and choose a clear channel away from any interference.
How much power does the PTP 600 Series transmit? At all times the PTP 600
Series operates within country / region specific regulations for radio power emissions.
In addition, the PTP 600 Series uses a technique known as Transmit Power Control
(TPC) to ensure that it only transmits sufficient radio power such that the other
antenna can receive a high quality signal.
How does the PTP 600 Series avoid interference from other devices nearby? At
initialization, the PTP 600 Series monitors the available frequency channels to find a
channel that is clear of interference. In operation 600 Series continuously monitors the
spectrum to ensure it is operating on the cleanest channel.
How does the PTP 600 Series integrate into my data network? The PTP 600
Series acts as a transparent bridge between two segments of your network. In this
sense, it can be treated like a virtual wired connection between the two buildings. The
PTP 600 Series forwards 802.3 Ethernet packets destined for the other part of the
network and filters packets it does not need to forward. The system is transparent to
higher-level management systems such as VLANs and Spanning Tree.
How does the PTP 600 Series provide security for data traffic? The PTP 600
Series has a range of security features. At installation time each link must be
programmed with the serial ID of its partner. The two ends of the link will only
communicate with one another, eliminating any chance of "man in the middle" attacks.
Over the air security is achieved through a proprietary scrambling mechanism that
cannot be disabled, spoofed or snooped by commercial tools.
Can I use Apple Macintosh OS X to control and monitor my 600 Series? Yes, but
there are some restrictions. Mozilla 1.6 or higher is recommended.
