Abstract
The utility model relates to a switching circuit device used for connecting external and internal wire modules. The utility model is composed of an external wire module which provides external wire resource, an internal wire module which provides internal wire resource and a switch circuit. A switching circuit with a double-pole double-throw switch is arranged between an interface of the external wire resource and an interface of the internal wire resource. The switching circuit comprises a circuit which is composed of six relay terminals. The power failure switching function of the utility model is completed fully and automatically without the need of any configuration or man-made interference. The utility model fartherst guarantees that a user's resource is not wasted, and provides convenience for the user.
Description
Technical field
The utility model relates to a kind of commutation circuit device that connects outer tape internal wiring module, particularly can save the commutation circuit device of the outer tape internal wiring module of resource.
Background technology
Existing outer wire module and tape internal wiring module all are independently, and outer wire module provides the outside line resource, and tape internal wiring module provides the interior lines resource.The outside line resource interface itself is equivalent to a ministerial standard telephone set, link to each other with the telephone wire of local network or the subscribers feeder of Private Branch Exchange PBX, but cooperate speech simulation card detection line bell signal, finish off-hook, on-hook action, receive the user key-press sign indicating number, realize digital recording and playback, also can differentiate the signal tone state of circuit, realize dialing automatically; The interior lines resource interface can be used to directly drive telephone set, and it needs external direct current power supply and could work, and after the system operation, telephone set one off-hook that the interior lines resource interface is connected can be started working, and when having connected the ringing-current source, also can allow ringing telephone stations.Cooperate the speech simulation card to use the dislodging machine state that to differentiate phone that line module connects, receive the user key-press sign indicating number, realize digital recording and playback.But externally under the situation of Ting Dianing, outer wire module and tape internal wiring module all can not be worked, and this just causes the waste of user resources, also bring some inconvenience to the user simultaneously.
The utility model content
The purpose of this utility model is to solve that when having a power failure resource is not wasted and commutation circuit device that tape internal wiring module outside a kind of the connection is provided.
The utility model is achieved in that what the utility model was made up of the outer wire module that the outside line resource is provided, the tape internal wiring module that the interior lines resource is provided and commutation circuit, be provided with the double-point double-throw switch commutation circuit between outside line resource interface and interior lines resource interface, described commutation circuit comprises the circuit of being made up of six relay terminals.When the energising operate as normal, power supply produces the control signal of double-point double-throw switch on the utility model, and the interior lines resource is connected on the telephone set, and first relay terminal and second relay terminal are connected on the 3rd relay terminal and the 4th relay terminal; The outside line resource interface is connected to the outside line from office side or switch, is in off-state with local exchange switch.When sudden power, because the control signal that power supply produces disappears, relay is replied initial condition, interior lines resource interface and telephone set arrival end switch disconnect, the switch closure of outside line resource interface and telephone set arrival end, first relay terminal and second relay terminal are connected on the 5th relay and the 6th relay terminal, promptly directly carrying out work from switch or the next signal converting of local side to local exchange switch.
The utlity model has the power failure handoff functionality, guarantee that to greatest extent resource is not wasted when having a power failure.
Description of drawings
Fig. 1 is that schematic diagram is switched in outer interior lines power failure of the present utility model.
Embodiment
As shown in Figure 1, the utility model is made up of the outer wire module 11 that the outside line resource is provided, the tape internal wiring module 10 that the interior lines resource is provided and commutation circuit 7, is provided with double-point double-throw switch commutation circuit 7 between outside line resource interface 11 and interior lines resource interface 10.When the energising operate as normal, power supply produces the control signal of double-point double-throw switch on the module, interior lines resource interface 10 is connected on the telephone set 8, and first relay terminal 1 and second relay terminal 2 are connected on the 3rd relay terminal 3 and the 4th relay terminal 4; Outside line resource interface 11 is connected to the outside line from office side or switch 9, is in off-state with local exchange switch 8.When sudden power, because the control signal that power supply produces disappears, relay is replied initial condition, interior lines resource interface 10 disconnects with telephone set 8 arrival end switches, the switch closure of outside line resource interface 11 and telephone set 8 arrival ends, first relay terminal 1 and second relay terminal 2 are connected on the 5th relay terminal 5 and the 6th relay terminal 6, promptly directly from office side or the signal converting of switch 9 carry out work to local exchange switch 8.
Under the energising normal condition: the first via of the present utility model is an outside line resource interface 11, itself is equivalent to a ministerial standard telephone set, links to each other with the telephone wire of local network or the subscribers feeder of Private Branch Exchange PBX.But cooperate speech simulation card detection line bell signal, finish off-hook, on-hook action, receive the user key-press sign indicating number, realize digital recording and playback; Also can differentiate the signal tone state of circuit, realize dialing automatically.
Of the present utility model the second the tunnel is interior lines resource interface 10, can be used to directly drive telephone set, and it needs external direct current power supply and could work.After system's operation, telephone set 8 one off-hooks that interior lines resource interface 10 is connected can be started working.When having connected the ringing-current source, also can allow ringing telephone stations.Cooperate the speech simulation card to use the dislodging machine state that to differentiate phone that line module connects, receive the user key-press sign indicating number, realize digital recording and playback.
Under situation about having a power failure: the commutation circuit 7 on the module works, and first via outside line 11 on the module is transferred on the telephone set 8 that the second tunnel interior lines 10 are connect, thereby realizes the power failure handoff functionality.Above conversion is to finish fully automatically and without any need for configuration and artificial disturbance, guarantee that to greatest extent user's resource is not wasted, and provides convenience for the user.
Claims (2)
