Transmit Sync Input
If the APs in the cluster
• receive sync from a CMMmicro or CMM4, select Sync to Received Signal (Power Port).
• receive sync from a CMM2, select Sync to Received Signal (Timing Port).
• are self timed, select Generate Sync Signal.
Link Mode
For AP to SM frame calculations, select Multipoint Link.
AES, 2X Rate, Encryption Enabled
This value is not settable by the operator.
Max Range
Set to the same value as the Max Range parameter is set in the AP(s).
Platform Type Transmitter
Use the drop-down list to select the hardware series (board type) of the AP.
Platform Type Receiver
Use the drop-down list to select the hardware series (board type) of the SM.
Frequency Band
Use the drop-down list to select the radio frequency band of the AP and SM.
Downlink Data
Initially set this parameter to the same value that the AP has for its Downlink Data parameter
(percentage). Then, as you use the Frame Calculator tool in Procedure 38, you will vary the value
in this parameter to find the proper value to write into the Downlink Data parameter of all APs in
the cluster.
PMP 100 Series APs offer a range of 1% to 99%, and default to 75%. PMP 400 Series APs offer a
range of 1% to 90%, and default to 75%. The value that you set in this parameter has the following
interaction with the value of the Max Range parameter (above):
• The default Max Range value is 5 miles and, at that distance, the maximum Downlink Data
value (90% in OFDM) is functional.
• Where Max Range is set to 6 to 10 miles, Downlink Data should be set to not greater than
85%. This lesser maximum avoids registration problems for nearby SMs. The user interface
of the OFDM AP automatically imposes the lesser maximum.
