6.2.3.3. Status LEDs
The Status LEDs indicate various synchronization and GPS functioning, as
described in the table below.
Table 6-8: Status LED Description
LED Color Status Meaning
HSP (Hop
Synchronization
Process)
Green
On
BSDU synchronization process is
active
Only right LED is on Synchronization process is starting
Both LEDs are on BSDU is the master unit
Only left LED is on BSDU is a slave unit
State (two LEDs)
Green
Both LEDs are off
BSDU synchronization pulse lost
(i.e. no synchronization)
On
GPS antenna is connected to the
BSDU
GPS Green
Blinking Receiving a satellite signal via GPS

Process Pulse)
Green
On Change state for the HSP pulse
6.3. SDA-1/48V
The SDA-1/48V is a compact indoor adapter especially designed for use when
available power source is 48VDC (i.e. no AC power supply), and when no
synchronization is required (i.e. in licensed bands). The SDA-1/48V connects to the
BSR by a standard CAT 5 cable, providing Etherent and power interfaces.
6.3.1. Physical Dimensions
The SDA-1/48V physical dimensions are described in the table below.
