Descriptions
The remote power supply unit is designed to supply remote power via the communication cable of trunk line amplifiers (ULM) in the absence of local power supply.
Scopes
- Extraction of galvanically isolated unregulated ULM supply voltage;
- “Wire-to-ground” or “wire-to-wire” operation;
- Dropping of a voice signal for ULM;
- Translation of a voice signal from ULM into a line;
- Line loopback in the event of a break and removing loopback in reactivation;
- Lightning protection for input and output circuits.
