Description

A kind of miniature digital subscriber line access multiplex

Technical field

The utility model relates to general field, relates in particular to a kind of miniature digital subscriber line access multiplex.

Background technology

At present, DSLAM (Digital Subscriber Line Access Multiplexer, digital subscriber line access multiplex) is the main access device as DSL (Digital Subscriber Loop, Digital Subscriber Loop).DSLAM commonly used comprises ply-yarn drill and master control power board two class basic modules, and from control and management, each ply-yarn drill all needs a controller to finish monitoring management to it, and can and the master control power board carry out communication.On business, each ply-yarn drill also needs service convergence is arrived the master control power board, and in case of necessity, ply-yarn drill needs that also business is had certain processing capabilities.

The general structure of above-described DSLAM is a kind of distributed treatment pattern.For a large amount of user managements of concentrating of processing, and complicated service is necessary.But be applied to insert under the situation of small number of users, it is too complicated that this DSLAM structure commonly used just shows, thereby increased cost, causes the unnecessary wasting of resources.Therefore just need a kind of DSLAM simple in structure to insert small number of users, and on overall architecture, can realize the low cost of trying one's best as remote end module.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of miniature digital subscriber line access multiplex, inserts small number of users and realizes low-cost on overall architecture as remote end module.

In order to solve the problems of the technologies described above, the utility model provides a kind of miniature digital subscriber line access multiplex, comprise: a plurality of ply-yarn drills, the core bus module, the master control power board, wherein, described each ply-yarn drill comprises a plurality of xDSL cover blade units, and (the x sign is uncertain, because DSL has ADSL, VDSL, multiple technologies such as SHDSL, it makes a general reference multiple DSL technology), described core bus module comprises service bus and management bus, described master control power board comprises controller and service convergence and processing unit, wherein, ply-yarn drill links to each other with the master control power board by the core bus module, it is characterized in that described each ply-yarn drill further comprises: a plurality of control bus interfaces and a plurality of service bus interface, wherein, described each xDSL cover blade unit is by corresponding each control bus interface and each service bus interface link to each other with described management bus and service bus with it.

Wherein, described controller links to each other with management bus in the core bus module, by management bus each xDSL cover blade unit on the ply-yarn drill is carried out initialization and the port of each xDSL cover blade unit is carried out parameter configuration.

Wherein, described service convergence and processing unit link to each other with service bus in the core bus module, by service bus collect business data flow on the system uplink direction from each xDSL nest plate unit port and it is handled after sending to network.

Wherein, described service convergence and processing unit link to each other with service bus in the core bus module, and the business data flow that on the system descending direction network is sent by service bus sends to each corresponding xDSL nest plate unit port respectively.

Miniature digital subscriber line access multiplex described in the utility model inserts small number of users as remote end module, has realized low cost on overall architecture.

Description of drawings

Fig. 1 is the structural principle block diagram according to the described a kind of miniature digital subscriber line access multiplex of the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

With reference to figure 1, be the structural principle block diagram of the described a kind of miniature digital subscriber line access multiplex of the utility model embodiment.Specifically comprise: a plurality of ply-yarn drills, core bus module, master control power board, wherein, ply-yarn drill links to each other with the master control power board by rear panel module.

Ply-yarn drill comprises, a plurality of xDSL cover blade units, a plurality of control bus interface, a plurality of service bus interface, wherein, described each control bus interface and each service bus interface with link to each other with their corresponding each xDSL cover blade units.The control bus interface of described ply-yarn drill and service bus interface are connected with the master control power board through the core bus module.According to the type difference of the xDSL cover blade unit that adopts on the ply-yarn drill, business interface can be interfaces such as UL2, POSPHY, MII.For reducing the complexity of system, the ply-yarn drill in the miniature DSLAM can adopt the xDSL cover blade unit of identical services interface type, adopts the UL2 bus interface such as the ADSL chip, and VDSL adopts the POSPHY bus interface.The business of each port all converges on the master control power board like this.

In addition, if xDSL cover blade unit can be supported in-band management, management can be finished by service bus, so also can not use and management bus.

The core bus module comprises, management bus and service bus are shared by described a plurality of ply-yarn drills.Wherein, described management bus is used for the configuration management transmission of Information, and host (main frame) interface with xDSL cover blade unit links to each other usually, simultaneously, management bus also links to each other with the bus interface of controller on the master control power board, for example Local Bus (local bus) interface.Described service bus is used for the transmission of business information.

The master control power board comprises, controller and service convergence and processing unit.Wherein, described controller is finished initialization to the xDSL on ply-yarn drill cover blade unit, and the port arrangement parameter of overlapping blade unit for each xDSL, and controller is also finished the configuration management to the master control power board.And described service convergence and processing unit are used for the business data flow of collecting is handled.

The concrete workflow of miniature DSLAM in system is: the controller on the master control power board, the master control power board is managed for configuration, by management bus, the cover of the xDSL on ply-yarn drill blade unit is carried out initialization again, and the port of each xDSL cover blade unit is carried out parameter configuration.If at system uplink direction (from user-to-network), service convergence and processing unit are collected business data flow by service bus from the port of each xDSL cover blade unit, send to network after treatment.If in system descending direction (from the network to user), the business data flow that service convergence and processing unit are sent network by service bus, sends to the port of corresponding xDSL cover blade unit respectively.As required, controller can carry out real-time configuration management to the port that xDSL overlaps blade unit by management bus.

Have only xDSL cover blade unit on the described ply-yarn drill of the utility model embodiment, do not have controller, also do not have Service Processing Module.The control bus interface of ply-yarn drill and service bus interface are connected with the master control power board through backboard.All management and Business Processing all concentrate on the main control module to be finished.

The application of miniature DSLAM described in the utility model is a remote end module, and port is less, and functional requirement is lower, therefore, adopt the pattern that focuses on, all management and traffic handing capacity are concentrated on the master control power board, be feasible, so just greatly reduce the complexity and the cost of system.
