4.5. Connecting BSR to the Backhaul Network
The BSR connection to the customer’s backhaul network depends on the base
station’s configuration:
! For base stations consisting of single BSRs, the connection to the backhaul is
through the SDA
! For base stations consisting of multiple BSRs, the connection to the backhaul is
through the BSDU.
4.5.1. Through the SDA
For a base station consisting of a single BSR, the BSR’s power supply and
connectivity to the backhaul network is provided by the SDA. The SDA is typically
installed at the subscriber’s premises, but in such a scenario, the SDA can also be
used at the base station. For a detailed description of the SDA, see Chapter 8,
“Installing the SPR and SDA”.
