Problems solved by technology

The use of this transmission device has the following disadvantages: 1. Its control process is complicated, the transmission speed is slow, the anti-interference is poor, the reliability is not strong, and it is easy to have code errors; 2. Each managed service line card must have a UART interface The minimum system circuit composed of a CPU (single-chip microcomputer) chip and necessary peripheral devices (memory) of the device increases the cost of the service line card, especially when a framed communication device is inserted into multiple service line cards, the cost reduction is particularly obvious

Embodiment Construction

[0030] The present invention will be further described in detail with an embodiment below, but it should be noted that the protection scope of the present invention is not limited to this.

[0031] Such as figure 2 As shown, a main control card reading line card type device includes: a main control card, a backplane and at least one read type business line card. The main control card contains a CPU, a CPLD chip and a frame type. The number of business line cards corresponding to the communication equipment slot number SLOT_ID and data exchange processing module; each read type line card contains a CPLD, business line card type Card_id and data communication module. The CPLD of the main control card is connected to the CPU of the main control card through the extended Local bus. The CPLD of the main control card is extended by its GPIO to expand a 4-bit data bus Data_bus[3:0] and a 3-bit address bus Address_bus[2:0] And 1 bit read enable Card_id_oe signal. The CPLD of each ...

Abstract

The invention discloses a device for enabling a master control card to read the type of a service line card. The device for enabling the master control card to read the type of the service line card comprises a master control card, a backplane, at least one service card with the line card type being read. The master control card comprises a CPU, a CPLD, a SLOT_ID slot position information signal and a data-switching center. Each service card with the line card type being read comprises a CPLD. The backplane is used as a service data and management information channel which connects the master control card and each line card. The invention further provides a method for enabling the master control card to read the type of the service line card. By the adoption of the device and method for enabling the master control card to read the type of the service line card, the process that the master control card reads the type of the service card is simplified, so that a CPU minimum system circuit of the service line card is saved, and the cost of a whole frame type device is reduced.

Description

Technical field [0001] The present invention involves the field of communication technology, especially the router, switch, EPON (Ethernet Passive Optical Network Ethernet Source) communication system has a variety of data exchange fields composed of different businesses. It specially involves a main control card read business line.Card type method and device. Background technique [0002] With the development of network communication, the people's increasing requirements for bandwidths are increasing, and multi -business network broadband with large capacity and high density has become more and more needed. Frame communication equipment has become more and more popular.Frame devices such as routers, switches, EPON, are generally composed of main control cards, back panels and various business line cards.Among them, the main control card is the control management center of the entire device, including the CPU (Central Processing Unit central processor), memory and necessary perip...
