Abstract
This invention discloses a system for line powering in communications. The system for line powering includes a power supply at the central office and remote power supply units (PSUs) connected to the power supply, wherein the power supply at the central office comprises at least two central office PSUs, and the central office PSUs provide power for the remote PSUs after being connected in parallel. At least two central office PSUs are set and connected in parallel to provide power for the remote PSUs, which provides redundant power backup for the remote PSUs and ensures reliability of normal communications in the network communication system. This method also helps to reduce the number of PSUs at the central office power supply part, to save space of the equipment room and to facilitate monitoring of central office PSUs. Thereby, this solution achieves reliable communication services, high integration of central office equipment and cost-effective network communication system.
