The BSR connects to the provider’s backbone network through either the WipLL
BSDU or WiPLL SDA Ethernet switch, depending on the Base Station’s
configuration:
 Base Station consisting of a single BSR: connection to the backbone may be
through an SDA
 Base Station consisting of multiple BSRs: connection to the backbone is
through a BSDU.
6.5.1. Through an SDA
For a Base Station consisting of a single BSR, the BSR’s power supply and interface
to the backbone network is provided by an SDA, which is typically used at the
subscriber’s premises. For a detailed description of the SDA, see Chapter 9,
“Installing the SDA”.
