Abstract
Disclosed herein are methods and systems for silent start when connecting a point-to-point (P2P) customer premises equipment (CPE) to a fiber access network. The P2P CPE may boot in a silent mode (by disabling an upstream optical transmitter) when the P2P CPE is connected to the fiber access network using a simplex fiber. Upstream transmissions are not sent by the P2P CPE unless a valid downstream signal with expected characteristics is detected by the P2P CPE. A valid downstream signal determination may indicate that the fiber access network is a P2P access network. A variety of characteristics may be used to validate the downstream signal including wavelength, a range of wavelengths, a line coding, a frame format, parity data, point to multipoint network information, point to point network information, logical link identifier, and a multi-point control protocol.
