BRX-VDSL2 devices are typically powered from the POTS sealing current (-48V) originating from
the DSLAM or the Central Office (CO). This is illustrated by Figure 16 below:

The BRX-VDSL2 devices can also be powered from a Positron BRX Power Injector providing the
required -48Vdc sealing current via the POTS combiner circuitry of the DSLAM. This is illustrated
by Figure 17 below:
