4.5. Connecting BSR to the Backhaul Network
The BSR connection to the provider’s backhaul network depends on the base
station’s configuration:
! Base station consisting of a single BSR: connection to the backhaul is through
the SDA
! Base station consisting of multiple BSRs: 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 9,
“Installing the SDA”.
The BSR-to-SDA cable connection configurations are as follows:
! Connectors:
! BSR: 15-pin D-type male (only 8 pins are used)
! SDA: 15-pin D-type male (only 8 pins are used)
! Cable: straight-through CAT-5
