Description

The smart phone dialing limiter

The utility model belongs to a kind of communication apparatus, particularly a kind of smart phone dialing limiter.

The phone dialing limiter of Xiao Shouing mainly contains two kinds in the market.A kind of is fixing limit dialing, formulates when this number made by factory, can not change later on.A kind of is own coding, after pinning an item, all numbers relevant with this item all are lockable, as lock the first for " 1 " number, all the first number all being lockable for " 1 ", particularly shortcode such as fire alarm 119, robber and police 110 also is lockable, and use is very inconvenient like this, and national postal and telecommunication entities do not allow yet simultaneously.Existing dialing limiter also all exists the string phenomenon, and what promptly limit was dialed number is easy to seal in the local network, for the local telephone network exchange increases burden, influences the unimpeded of communication.This also is that postal and telecommunication entities are unallowed.In addition, all dialing limiters can be used improper means, add means such as button as hooking or hooking and eliminate former dail-limiting number, make switch on.Existing dialing limiter all can not be limit the air time again, can not limit the figure place of dialing the number, and D.C. resistance is big, does not all reach the networking standard of national regulation.

The purpose of this utility model is to overcome weak point of the prior art and provides a kind of dail-limiting number both can arbitrarily be set at any time, arbitrarily is set the air time, and the not number of string again, D.C. resistance is little can reach the smart phone dialing limiter that country networks and requires.

The utility model compared with prior art has following advantage:

1, it is wide scope to be set.Can establish 4 groups of devices totally 39 dail-limiting numbers: 1 item can be established 10; 2 items can be established 10; 3 item first places are 1 establish 10, and 3 item first places are not 1 establish 9.The user can also be provided with and revise the number that the world, domestic, farm work, local telephone network, mobile telephone, shortcode etc. need limit to dial at any time arbitrarily, and can cancel does not at any time need barred code yet; The figure place and the limiting call time of dail-limiting number can also be set.

2, strong security can the classification Password Management.Dialing limiter is established administrator password and accessing to your password, and administrative staff grasp administrator password, utilizes administrator password that dail-limiting number can be set or revises administrator password and access to your password.The user of service only grasps and accesses to your password, and accesses to your password after the input, and all dail-limiting numbers are all opened, and can put through arbitrary numbers.

3, can realize the Remote maintenance.Use the dialing limiter user to break down, as administrator password or access to your password and forget or crash, confusion is set, can not recover.Can with manufacturer's telephone contact, manufacturer available phone remote control recovers repertoire.

4, owing to taked the high frequency inverter circuit supply, the D.C. resistance of dialing limiter is significantly reduced, therefore can reach national networking standard.

5, safe and reliable.Dail-limiting number is as long as be provided with, with any improper means.As pulse dial-up hooking, the audio frequency dial-up is pinned means such as lifting hook switch earlier simultaneously with hook switch and number zero and can not be eliminated, and does not also have the string phenomenon.Converse after 15 sand, all limit dialing all lose function, therefore can not go out to manage the dropped calls phenomenon.

5, easy to use.Mechanical lock and password limit are dialled and can be used simultaneously, also can use separately.
