Abstract

In the case of reverse power feeding, when you are replacing a DSL transmitter with a G.FAST DPU, how will you properly provision the subscriber. Since there is no TIP/RING voltage issues, other than the AC voltage of the ADSL transmission, the idea is simply that the DPU is connected in parallel to the DSL transmitter across TIP and Ring. (See Fig. 3). When the DPU senses power good, it switches the relay so that the data connection is supplied from the DPU and not the DSL transmitter.

Summary:  In the case of reverse power feeding,when you are replacing a DSL transmitter with a G.FAST DPU, how will you properly provision the subscriber. 

Since there is no TIP/RING voltage issues, other than the AC voltage of the ADSL transmission, the idea is simply that the DPU is connected in parallel to the DSL transmitter across TIP and Ring.  (See Fig. 3).  When the DPU senses power good, it switches the relay so that the data connection is supplied from the DPU and not the DSL transmitter.

1.       Stage 1- DSL  transmitter connected to subscriber receiver

2.       Stage 2- G.FAST (VDSL2) DPU with RPF capabilities are installed  but DSL still continue to provide service to subscriber

Q: do we need to disconnect all two wire of DSL  or one is enough ?
