Flashless optical network unit

摘要

A system, method, and computer program product for a flashless optical network unit (ONU) in a Passive Optical Network (PON) are provided herein. The method includes the steps of synchronizing on a downstream signal of an optical line terminal (OLT), receiving a first software from the OLT for its operation on a reserved downstream channel of the OLT, and storing the received first software in a volatile memory. The ONU does not pre-store the first software in a non-volatile memory.

主权项

1. An optical network unit (ONU) in a Passive Optical Network (PON), comprising:
a media access control (MAC) configured to synchronize to an optical line terminal (OLT) based on a downstream signal transmitted by the OLT, wherein the ONU receives a software from the OLT, wherein the software is periodically broadcasted by the OLT on a reserved downstream channel, wherein the ONU does not pre-store the software in a non-volatile memory; and wherein the ONU is configured to store instructions for a partial boot of the ONU; a volatile memory configured to store the received software; and a processor configured to fully boot, discover, range, and activate the ONU based on the received software stored in the volatile memory.
