Descriptions
LCU-4XEC1-01 is designed for operation on a communication line built on balanced cables (MKS 2x4x1.2). The unit mixes the signals of the SHDSL modem and the remote power supply voltage supplied from RPU-600-01 or RPU-700. It operates in conjunction with SM-4X4E-02S and the regenerator module. The unit provides “wire-to-wire” remote power input and communicate positive and negative buses of remote power supply. Also, the unit inputs service channel signals into the line via a wire-to-wire phantom circuit.
Scopes
- SHDSL signal input into the communication line;
- Remote power input into the communication line;
- Changing the RPS polarity in each direction;
- Organizing the service communication channel;
- Active speaker output;
- Integrated line input protection.
