AUTOMATIC ESTABLISHMENT OF ANALOG NETWORK TOPOLOGY

摘要

A method of detecting an RF connection in a network is disclosed. The method involves the use of a low-speed modem pair DC coupled to the RF connection to modulate a DC voltage onto the RF connection. Additionally, a method of signaling over an RF-over-fiber link is provided. The method includes modulating the bias voltage of a laser with a low-bit rate signal applied through a digital-to-analog converter, which is recovered using a low-speed analog-to-digital converter.

1. A method for detecting a user connection in an RF network, comprising:
providing a first low-speed modem DC coupled to a first node connected to a first side of a user connection; providing a second low-speed modem DC coupled to a second node connected to a second side of a user connection; with the first low-speed modem, modulating a DC voltage onto the user connection and detecting the modulated DC voltage using the second low-speed modem.
