Motorola PTP 500 Series User Manual page 132

The Wireless Configuration page contains the following fields:
Target MAC Address
This is the MAC Address of the peer unit that will be at the other end of the wireless link. This
is used by the system to ensure the unit establishes a wireless link to the correct peer. The
MAC Address can be found embedded within the serial number of the unit. The last six
characters of the serial number are the last three bytes of the unit's MAC address.
NOTE
A PTP 500 Series system is shipped as a pair of units with pre-loaded correct MAC
addresses. Target MAC addresses will only need to be entered if an existing unit has
to be replaced in the field or the units configuration has been erased.
Master Slave Mode
At this point it is necessary to decide which end will designate a Master. The Master unit is the
controlling unit with respect to the point-to-point link and its maintenance. The master
transmits until the link is made, while the Slave listens for its peer and only transmits when the
peer has been identified.
Link Mode Optimization
Optimizes the link behavior according to the type of traffic that will be bridged. There are two
modes to choose from: IP and TDM. For more information, see 3.8 "Link Mode Optimization".
Tx Max Power
This attribute controls the maximum transmit power the unit is permitted to use when installing
and executing the wireless link. The maximum setting for a particular region or country is
controlled by the License Key.
Platform Variant
Chooses between an integrated unit or a connectorized unit that requires an external
antenna.
Channel Bandwidth
Users can choose a variable channel bandwidth for the available spectrum. Values of 5 MHz,
10 MHz and 15 MHz can be selected.
Link Symmetry
(Master only) Values of "Adaptive", "3 to 1", "1 to 1" and "1 to 3" can be selected. The
adaptive setting allows link symmetry to vary dynamically in response to offered traffic load.
The remaining values select three options for fixed division between transmit and receive time
in the TDD frame of the master ODU. The first number in the ratio represents the time allowed
for the transmit direction and the second number represents the time allowed for the receive
direction.
The appropriate matching Link Symmetry is set at the slave ODU automatically. For example,
if Link Symmetry is configured as "3 to 1" at the master ODU, then the slave ODU will be set
automatically as "1 to 3". In this example, the master-slave direction has triple the capacity of
the slave-master direction.
