Description
The utility model relates to communication equipment, is a kind of access network equipment, specifically a kind of arrowband and broad-band overall led-in equipment.
Access network equipment mainly contains such three classes: 1, narrow band access equipment is used to insert narrow band service, as public switch telephone network PSTN business, integrated digital network ISDN business, Digital Data Net DDN business etc.2, broadband access equipment is used for the access band business, as asynchronous transfer mode ATM business, asymmetric high-speed figure loop ADSL business, LAN emulation LANE business etc.3, arrowband and broad-band overall led-in equipment, it can insert narrow band service and broadband services simultaneously, has the incorporate characteristics in arrowband and broadband.
Existing arrowband and broad-band overall led-in equipment generally have two kinds on implementation method: a kind of is that arrowband part and broadband part are relatively independent, they have the independently machine frame of controlling oneself respectively, be equivalent in form narrow band access equipment and broadband access equipment are stacked together, this mode does not realize the real fusion in arrowband and broadband, and equipment structurally consistency is poor; Another kind be with arrowband part and broadband part comprehensively in same machine frame, backboard adopts the local bus technology, this mode has overcome the shortcoming of first kind of mode, but the groove position relative fixed of arrowband part and broadband part, can not exchange, arrowband bus and wideband bus must provide simultaneously, cause the equipment cost height, are unfavorable for promoting the use of when only needing narrow band service or broadband services.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides that a kind of structural integrity is good, flexibility is strong, cost is low, arrowband and broadband not only can unify but also separable, can realize arrowband and broad-band overall led-in equipment that the arrowband seamlessly transits to the broadband.
The utility model comprises machine frame, is fixed on machine frame backboard and some veneers that are inserted in the machine frame behind.Backboard adopts global bus's technology, and arrowband bus and wideband bus can be provided simultaneously, and it is made up of three sub-backboards: the sub-backboard in arrowband, cummerbund backboard and the sub-backboard of interface.Veneer mainly contains narrowband board, broadband plate, the broadband integrated plate in arrowband and power panel etc.The broadband integrated plate in so-called arrowband, be meant and have arrowband function and broadband feature simultaneously or be the veneer of narrowband board and the service of broadband plate simultaneously, in other words, arrowband of the present invention function and broadband feature not only can be comprehensively in machine frames, can also be comprehensively on a veneer.Several universal vat positions are provided in the machine frame, be used to insert described veneer, these groove positions are all general to all veneers, do not have the branch of groove position, arrowband and groove position, broadband, thereby various types of veneers of mixed insertion flexibly in machine frame, narrow band service and broadband services can be provided simultaneously.
Provide the arrowband bus on the sub-backboard in arrowband, use for narrowband board; Provide wideband bus on the cummerbund backboard, use for the broadband plate; Separate between the sub-backboard in arrowband and the cummerbund backboard, wherein any one can only be installed during installation, also can two install simultaneously; Unified external connector is provided on the sub-backboard of interface, it is the external interface of equipment, be used for the business interface on the various veneers is caused device external, it can be attached on sub-backboard in arrowband or the cummerbund backboard, also can separate with the cummerbund backboard with the sub-backboard in arrowband in mode independently; Every veneer can only use in three sub-backboards, also can use wherein any two, also can three all uses.In the time only narrow band service need being provided, the cummerbund backboard can be installed, to reduce the cost of narrowband systems.When only needing broadband services, equally the sub-backboard in arrowband can be installed.
The utility model contrast prior art has following advantage: 1, comprehensively in a machine frame, various veneers such as narrowband board, broadband plate all have identical mechanical dimension, are the comprehensive hardware platforms in an arrowband and broadband for narrow band service and broadband services.With described hardware platform is basic module, can constitute the local side apparatus and the remote equipment of Access Network, makes the structure of local side apparatus and remote equipment just the same, and capacity can be realized smooth expansion by the module stack.Therefore, equipment structurally has good consistency; 2, the narrow/wide belt backboard of backboard was both separable, can install simultaneously again, in the time only need providing narrow band service, the cummerbund backboard can be installed, to reduce the cost of narrowband systems, when equipment need be expanded broadband services, again the cummerbund backboard is added, realize arrowband seamlessly transitting to the broadband.When only needing broadband services, equally the sub-backboard in arrowband can be installed.Therefore, equipment both can provide narrow band service and broadband services simultaneously, can provide narrow band service or broadband services separately again, and cost was low; 3, backboard adopts bussing technique, and each the groove position in the machine frame is general mutually, does not have the branch of groove position, arrowband and groove position, broadband, and the function of each machine frame is determined by the feature board that inserts and the software of operation.In the time will increasing new business or new function, only need to increase the veneer kind or change software to get final product, and do not need system configuration is done any change, equipment has very strong flexibility; 4, arrowband function and broadband feature not only can be comprehensively in machine frames, can also be comprehensively on a veneer, and the broadband integrated plate in promptly so-called arrowband; But 5, all independent design, making, debugging and maintenances of the sub-backboard in arrowband, cummerbund backboard and the sub-backboard of interface, can adopt the printed substrate of the different numbers of plies respectively, this helps shortening the Products Development cycle, improves the maintainability of equipment, reduces the cost of equipment.
The utility model is described in further detail below in conjunction with drawings and Examples:
