PBL38611-2 circuit equivalent, subscriber line interface circuit.
* Selectable overhead voltage principle
– All adaptive: The overhead voltage follows 0.6 VPeak < signals < 5 VPeak.
– Semi adaptive: T.
The PBL 386 11/2 emulates a transformer equivalent dc-feed, programmable between 2x25 Ω and 2x900 Ω, with short loop cu.
