Description

Based on network phone key switch

Affiliated technical field

The utility model relates to a kind of telephone exchange, particularly a kind of phone key switch.

Background technology

Phone key switch has analog and digital two kinds in the market.Along with development of telecom technology, analog phone key switch shortcoming is obvious day by day, is that mainly itself and many new softwares can not well cooperate, and cause many new functions to be restricted thereon.Though digital phone key switch has solved some shortcomings of analog phone key switch, it does not carry out the good technical cooperation with computer and network yet.Group telephone does not in the market also have network interface, and in the group telephone product of realizing linking to each other with local area network (LAN) by alternate manner, have only group's switch of indivedual foreign brand names to have at present, realize that now this function generally adopts industrial computer to add the pattern of integrated circuit board.This modular system cost height, the threshold height of maintenance and management, extremely difficult the grasp.Generally after installation engineer was finished initial configuration, system management just be nobody shows any interest in, and had had a strong impact on the efficient of system.

Summary of the invention:

The utility model provides that a kind of system cost is low, maintenance and management is easy, volume is little, at the bottom of the power consumption, good stability and the phone key switch of network interface is provided.

The technical solution of the utility model is: comprise outer line interface, interior line interface, connect by switching matrix between the inside and outside line interface, it is characterized in that: have the network processes part to be connected with outer line interface, interior line interface, switching matrix, described network processes partly comprises peripheral expansion assembly, the network interface components that built-in network is handled CPU and linked to each other with CPU.

The beneficial effects of the utility model are: have network interface, can make things convenient for access to LAN, finish recording by network, message and route, provide incoming information, the expansion of functions such as the duration of call.And have advantages such as volume is little, cost is low, maintenance is simple, general computernik can safeguard to have friendly user interface.Man-machine interface by the close friend is carried out system management, carries out inside and outside line grouping flexibly, and simultaneously, extension subscriber can will be registered as the extension number of oneself on any a part of machine, and Unsupervised member gets involved.Abundant traffic and charging statistical report form is provided.The general utility functions that possess conventional switch have phone registration, built-in IVR simultaneously, group busy, team exhales, extended telephone conversation is reminded, take the outside line time restriction, functions such as the grade of service, abbreviated dialing with oneself.

The form of the above-mentioned peripheral expansion assembly that links to each other with CPU is varied: such as program storage (EPROM, EEPROM, FLASH, SRAM etc.), data storage (SDRAM, DRAM, SRAM etc.), expansion mouthful (serial port, parallel port, I2C, I2S, HDLC, network interface etc.).

Be connected with the exchange processing section between above-mentioned network processes part and switching matrix, described exchange processing section comprises single-chip microcomputer and the peripheral expansion assembly that is connected with single-chip microcomputer.

The above-mentioned expansion that is connected with single-chip microcomputer comprises: program storage, suggestion voice E ²PROM, expansion RAM, calendar or rate, number E ²PROM and other extended device or interface etc.

Above-mentioned exchange processing section or network processes part are connected with serial communication port.

Embodiment

Embodiment one:

As shown in Figure 1, the present networks phone key switch comprises outer line interface 3, interior line interface 5, connects by switching matrix 4 between the inside and outside line interface, and network processes part 6 is connected with switching matrix, inside and outside line interface.As shown in Figure 2, network processes part 6 comprises built-in network processing CPU, FLASH ROM, DRAM and network interface 1 and serial communication port 2, and FLASH ROM, DRAM, network interface 1, serial communication port 2 are handled CPU (S3C4510B) with built-in network respectively and be connected.Handle CPU (S3C4510B) control switching matrix 4 by built-in network, and network interface 1 is provided.Owing to have network interface 1, can make things convenient for access to LAN, finish recording by network, message and route, provide incoming information, the expansion of duration of call or the like function.And have advantages such as volume is little, cost is low, maintenance is simple, general computernik can safeguard to have friendly user interface.Man-machine interface by the close friend is carried out system management, carries out inside and outside line grouping flexibly, and simultaneously, extension subscriber can will be registered as the extension number of oneself on any a part of machine, and Unsupervised member gets involved.Abundant traffic and charging statistical report form is provided.The general utility functions that possess conventional switch have phone registration, built-in IVR simultaneously, group busy, team exhales, extended telephone conversation is reminded, take the outside line time restriction, functions such as the grade of service, abbreviated dialing with oneself.

Embodiment two:

As shown in Figure 3, between above-mentioned network processes part 6 and switching matrix 4, can be connected with exchange processing section 7.As shown in Figure 4, exchange processing section 7 comprises single-chip microcomputer and the extender memory that is connected with single-chip microcomputer, suggestion voice E ²PROM, expansion RAM, calendar, rate number E ²PROM and other extended device or interface etc.As shown in Figure 5, built-in network processing CPU is connected with exchange processing section 7.1. in addition, present embodiment other technologies feature is all identical with embodiment one.
