Embodiment Construction

[0020] An implementation method of the present invention on SDH equipment will be described below in conjunction with the accompanying drawings.

[0021] figure 1 is a schematic diagram of a communication system to which a preferred embodiment of the present invention can be applied. like figure 1 As shown, the communication system includes a remote computer for network management. The remote computer is connected to an SDH communication device through an Ethernet interface, and the SDH communication device is connected to another SDH device through an ECC port, and the other SDH device can be further connected to other SDH devices, thus forming a communication system. In this way, through the ECC communication between SDH equipment, and the connection between the SDH equipment and the external network management computer through the Ethernet port. The network management computer can control and communicate with any SDH equipment. Here, each communication device may or ma...

Abstract

The communication system comprises the remote management computer and multiple communication equipment. Each communication equipment comprises the interface controllable and accessible remotely, the controller and PLD connected to the controlled needed to load and upgrade. The method includes following steps. Files needed for upgrading PLD is transferred to communication equipment, where the PLD is located at, through remote access interface and remote management computer. With the file being received, the communication equipment upgrades the PLD, and feeds the upgrading result back to the management computer. The method raises maintainability of electron devices greatly.

Description

technical field [0001] The invention relates to file loading of programmable logic devices, in particular to a method for remotely loading / upgrading programmable logic devices in a communication system and a communication system thereof. Background technique [0002] Programmable logic devices (PLDs) are widely used in electronic communication equipment and are popular because they can dynamically change the logic. PLD loading is usually implemented using a PC or PLD is loaded by itself when powered on using PROM storage. However, communication devices in a communication system are often widely distributed. [0003] When the problem caused by this, if there is a PLD logic in a communication system that needs to be updated, a person needs to go to the site to manually load or replace the PROM. Contents of the invention [0004] For these inconveniences, the purpose of the present invention is mainly to provide a method for upgrading PLD without going to the site. [0005...
