Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of main frame that is used to connect local side apparatus and user terminal.
Background technology
Main frame (Main Distribution Frame; MDF) be a kind of continuing and safeguard in the communication line; be used to connect local side apparatus and user terminal; also have defencive function and test port, thus realize to circuit overvoltage and overcurrent protection, fault warning and to the test of circuit.
See also Fig. 1, the main frame 10 of prior art comprises safety wire connection row 11 (also claiming outer wire module) and test line bank 12 (also claiming tape internal wiring module).Wherein, described safety wire connection row 11 is installed in the face in upright arrangement of main frame 10, wire jumper 14 in the outside line 13 that is used to continue (as the service cable etc.) drawn game, thereby access user terminal 60; Described test line bank 12 is contained in the line face of main frame, and wire jumper 14 in the drawn game of the interior lines 15 of continuing (as office cable etc.) is used for realizing being communicated with local side apparatus 70.Described safety wire connection row 11 is connected by intra-office wire jumper 14 with test line bank 12, realizes user's numerical selection and service fulfillment function, and the service that comprises the voice-and-data function generally is provided.In order to prevent that overvoltage and/or overcurrent from working the mischief to calculator room equipment and personal safety, Security Unit 16 is installed in safety wire connection row 11 further.
Wherein, local side apparatus 70 can be access devices such as switch, comprise narrow band services such as speech business and dialing are provided narrow-band devices, the broadband device of broadband services etc. is provided.
In general, main frame in the communication line need carry out regular wire jumper work, and the connection of the wire jumper of the main frame 10 of prior art shown in Figure 1 needs manual operation: earlier intra-office wire jumper 14 1 ends are penetrated from safety wire connection row 11 1 sides, 11 block on safety wire connection row; According to the position of Subscriber Number on line test line bank 12, intra-office wire jumper 14 is passed jumper ring (figure does not show) put test line bank 12 again, will penetrate firmly clamping the respective aperture of intra-office wire jumper 14 above test line bank 12 to the Subscriber Number place.
Because connecting, the wire jumper of prior art main frame 10 needs manually to operate to the scene, and unattended Access Network business site is relatively disperseed, distribute telephone numbers, upgrading service is more frequent, therefore nervous the and cost rising of human resources caused in human cost higher developed country and area.
For adopting a pair of outside line that the communication system of broad band telecommunication service and arrowband telecommunication service is provided simultaneously, as ADSL over POTS, ADSL over ISDN, VDSL over POTS, VDSL over ISDN etc., need great amount of manpower to carry out wire jumper connection work especially at the connection voice and data network, seriously hindered professional applying.
See also Fig. 2, a kind of main frame 20 of prior art can adopt a pair of outside line 23 simultaneously user terminal 60 to be opened narrow band service and broadband services, comprise safety wire connection row 21 and test line bank 221,222 and 223, normally thousands of cables bundles and forms wire harness at main frame 20 upward wirings.
If by safety wire connection row 21, intra-office wire jumper 241 and test line bank 221 are communicated with user terminal 60 and local side narrow-band devices 71, open broadband services on this basis, need earlier intra-office wire jumper 241 to be disconnected, again intra-office wire jumper 242 is connected to test line bank 223, and then by interior lines, broadband 251 connection test line banks 223 and the speech separator (Splitter that is integrated in the local side broadband device 72, SPL) 73, by speech separator interior lines 252 speech separator 80 is connected to test line bank 222, connects test line bank 222 and test line bank 223 by wire jumper 243 again.That is to say, in the time of will broadband services being installed, all need to determine a certain wire jumper at every turn, it is disconnected from original equipment, and then be connected to speech separator 80.This complexity causes manually carrying out wire jumper connection work and is very easy to make mistakes, and in addition, wire jumper connection work is very consuming time, so cost is also very expensive.
Seeing also Fig. 3, is the main frame of another kind of prior art.Described main frame 30 adopts wide and narrow strip interior lines line bank 321 to replace traditional test line bank, speech separator 80 is told from local side broadband device 72 on the wide and narrow strip interior lines line bank 321 that is inserted in main frame 30, only need and connect between the wide and narrow strip interior lines line bank 321 of interior lines, arrowband 351 when opening the broadband at the test line bank 322 that connects interior lines, broadband 352, connect local side broadband device 72 by broadband wire jumper 342, just can finish the open-minded of broadband services, reduced the quantity of wire jumper, can simplify the operation.But described prior art still needs to carry out the operation of artificial wire jumper, and cost is still higher and efficient is lower.
See also Fig. 4, in order to overcome foregoing problems, industry develops and a kind of full automatic main frame.Described main frame 40 adopts mechanical structure, comprises stepping motor 41 and jockey 42; Described jockey 42 is used for realizing being connected of switch 73 and user terminal 60, the bread board that uses during similar debug circuit, and its commutative relation is divided into 3 grades, comprises a plurality of connecting plates 421 with tie point 422.When needs connected same user, just by the operation of far-end control system (figure does not show) control step motor 41, the tie point 422 on connecting plate 421 was plugged a metal needle (figure does not show), thus definite circuit that need connect.
The main frame 40 of prior art can be realized the automatic operation of wire jumper, but it has the some shortcomings part: at first, reliability is not high, because 40 employings of full automatic main frame is that mechanical structure and stepping motor combination form, its complex structure and reliability are not high.Secondly, cost is higher, because the main frame 40 of prior art uses a large amount of precision optical machineries and electronic technology, its cost approaches the cost of switch.
