In addition, the BSDU Zoom window provides Status LEDs that indicate the status
of the GPS, as described in the table below:

21.2.5. Task 4: Define Synchronization for BSDUs
You can enable synchronization among daisy-chained BSDUs at a Base Station. The
BSDU that controls the synchronization (referred to as
Master BSDU), depends on
whether a GPS is implemented:
GPS implemented: BSDU to which the GPS is physically connected receives
satellite time signals from the GPS, and therefore, controls the synchronization
between the BSDUs. This BSDU is referred to as the
Master BSDU.
Without GPS: one of the BSDUs (1 to 4) can be defined to control
synchronization (i.e. Master BSDU). If no BSDU is defined, then the first
powered-on BSDU automatically controls synchronization.
Notes:
1) Ensure BSDU synchronization ports are connected between BSDUs. For a
detailed description on cabling these ports, refer to the
ASWipLL Hardware
Installation Guide .
2) Ensure identical frequency table size is configured for all BSDUs.
You need to define the number of frequencies composing the frequency table used
for BSR-SPR wireless communication. This is later used for enabling
synchronization of multiple BSRs by the BSDU. In addition, you need to define a
unique synchronization ring ID number for the BSDUs.
In the configuration example, the GPS is connected to BSDU 10.0.0.5, and
therefore, this BSDU will automatically be assigned as the Master (and BSDU
10.0.0.6 as the slave). In the following procedure, you need to assign BSDU 10.0.0.5
ring ID
8 , and BSDU 10.0.0.6 ring ID 5 .
