Embodiment Construction

[0032] figure 1 It is a schematic diagram of EPON access system. Such as figure 1 As shown, the EPON access system is composed of OLT, ONU and ODN. The OLT includes a main control board, an uplink disk, a line card and an AC16 disk. The line card or the AC16 disk is connected to a remote OUN device, wherein the AC16 disk handles voice services, including NGN-based voice and POTS-based voice. The upgrade of the ONU equipment is mainly handled directly by the line card, but the upgrade of the IAD is directly handled by the AC16 disk because it involves voice services. The automatic upgrade configuration parameters of the EPON access system are sent by the network management computer (or through the serial port command line), and the upgrade file is provided by the FTP server for download.

Abstract

The invention discloses an ONU automatic upgrading method in an EPON access system, which includes steps that a webmaster computer sends automatic upgrading enabling configuration parameter and instruction; a master control disc stores the configuration parameter and sends the configuration parameter to designed line cards; each line card modifies and stores the configuration parameter; the master control disc unloads upgrading file and stores the upgrading file to local buffer memory; the master control disc notices on-line line cards or AC 16 disc to unload and store the upgrading file; the line card store the upgrading file to the local buffer memory; and designed ONU obtains the upgrading file from the line cards or the AC 16 disc, writes in FLASH of the ONU to complete upgrading and reporting the upgrading result. The invention can once realize automatic upgrading of all ONUs under the line cards, even if the OUNs are not on-line when configuring , the invention can realize upgrading for the ONUs after the OUNs are on-line next, thereby increasing operation maintain efficiency in the EPON access system.

Description

technical field [0001] The invention relates to an ONU management method in an Ethernet passive optical network, in particular to an ONU automatic upgrade method in an EPON access system. Background technique [0002] Ethernet Passive Optical System (EPON) is a new type of optical fiber access network technology. It adopts a point-to-multipoint structure and passive optical fiber transmission to provide various services on the Ethernet. It adopts PON technology in the physical layer, uses Ethernet protocol in the link layer, and realizes the access of Ethernet by using the topological structure of PON. Therefore, it combines the advantages of PON technology and Ethernet technology: low cost; high bandwidth; strong scalability, flexible and fast service reorganization; compatibility with existing Ethernet; convenient management and so on. [0003] A typical EPON system consists of OLT, ONU and ODN. OLT (Optical Line Terminal) is placed in the central computer room. The OLT ...
