Flexible Hopping Definition Mode

General
The process of setting the hopping sequence using the Flexible Hopping
Definition mode includes the following steps:
1. Select the frequencies to be used using the Flexible Hopping
Definition menu
2. Define the method of generating the basic hopping sequence based
on the set of selected
sub-menu. The method of generating the basic sequen
defines the hopping shift mechanism for generating d
hopping sequences.
3. If two or more AUs (and/or CXs) are co-located, configure the
Spanning Factor parameter to define a different hopping sequence
for each AU in orde
The Flexible Hopping Definition menu enables defining the hopping
frequencies and the method of scrambling the selected frequencies for
generating the basic hopping sequence. It also enables to view the
selected hopping frequencies and the current hopping sequence (based
on the previous selections made before the last reset). The new
selections will come into effect only after the next reset.
The default selection (including the case where all frequencies were
deleted) is a single frequency, 915 MHz.
Both CX/AU and all SU that will be associated to the CX/AU must be
configured to the same hopping parameters. The SU does not learn the
hop channels from the AU.
NOTE
The CX/AU and all SU that that will be associated to the CX/AU must be
configured to the sam
channels from the AU.
Refer to the technical bulletin, "BreezeACCESS 900 Co-location
Installation Guidelines", for specific instructions on how to properly
install and configure the CX and AU units for operation in environments
where more than one unit will be operating.
