Hopping Sequence (Shift) Range and Default Value
The permitted range for the Hopping Sequence (Shift) parameter is from
0 to N-1, where N is the number of hopping frequencies.
The default is 0

status of the unit and allows defining a new status. When several
AUs that use the same hopping set and different hopping sequences
(or the same hopping frequencies and different hopping shifts when
in HDM mode) are co-located, their operation should be
synchronized in terms of hopping sequence initialization and
timing. If a BS-GU GPS module is not used for synchronization,
then one AU must be specified as a Master unit and all other units
must be specified as Slave units. When a BS-GU is used, all AUs
must be configured to Slave mode. Available options are:
" Idle – No synchronization (stand-alone operation)
" Master – The AU that serves as a Master unit providing
synchronization signals to the Slave units
" Slave – An AU that operates as a Slave
The default is Idle.
WARNING:
When using a GPS system for synchronization, all AUs in the chassis must be set
to Slave.
NOTE:
Synchronization is not allowed by the radio regulations in certain countries. In units
using such standards, the Hopping Sync option is not supported. See Table 2-3‚
page 2-40 for information on synchronization support in the standards of various
countries.
ESSID Parameters
The ESSID is a string used to identify a wireless network. It prevents the
unintentional merging of two co-located wireless networks. An SU can
only associate with an AU that has an identical ESSID. To facilitate easy
additions of SUs to existing deployments, where different ESSIDs are
used in neighboring sectors, a secondary "global" ESSID, namely
Operator ESSID, is available in the AU.
! ESSID – The ESSID (Extended Service Set ID) of the unit. Use
different ESSIDs to segment the wireless access network and add
security to your network.
Valid values: A string of up to 31 printable ASCII characters, case
sensitive.
