Description

The asymmetric digital subscriber line transmission system has the PSTN jockey of separation equipment

The present invention relates to a kind of asymmetric digital subscriber line (ADSL) transmission system, particularly relate to a kind of PSTN (public switched telephone network) jockey that in the ADSL transmission system, uses with separation equipment.

The ADSL transmission system sends/receives data on high frequency band, and uses the voice signal of existing telephone wire (being PSTN) transmissions/reception telephone service on low-frequency band, so as under the situation that does not hinder telephone service high speed transmission/reception data.Corresponding therewith, user one side of ADSL transmission system uses separation equipment to separate high-frequency signal and low frequency signal from the signal that sends by telephone wire, high-frequency signal is offered the user terminal of ADSL transmission system, and low frequency signal is offered the telephone terminal that is used for telephone service.

Fig. 1 represents a kind of structure of known separation equipment, and PSTN wherein is connected to DC (direct current) jointly and blocks and high-pass filtering part 100 and a low pass filter 102.DC blocks and the DC composition of the signal that high-pass filtering part 100 obstructions receive from PSTN, and the signal that DC is blocked carries out High frequency filter, its output signal is offered the ATU-R (at the ADSL transmission unit of dwelling end (Customer Promises End)) as the user terminal of ADSL transmission system again.102 pairs of signals that receive from PSTN of low pass filter carry out low-pass filtering, and will offer telephone terminal through the signal of low-pass filtering by a mark (signature) 104.Mark 104 has constituted a loop that is used for the AD/DC signaling, and provides bell signal for telephone terminal.Need provides the signal that passes through low-pass filtering from PSTN to the telephone terminal that is connected to the ADSL transmission system herein, so that telephone service is provided.

In general, have the phone that multi-section is installed separately in the residential housing, for example be contained in bedroom and the living room; For this reason need be when building residential housing molded in wall (burying) a plurality of telephone sockets (socket).Corresponding therewith, providing under the situation of data service to the user by the ADSL transmission system, the phone splicing ear that is installed in all phones in the building and all needs to have the separation equipment that the independent separation equipment of installing or preparation be connected to telephone terminal should be connected to all phones in the building, so that provide normal telephone service by telephone terminal.All phones that a phone splicing ear of separation equipment is connected in the building can make the telephone socket of having installed (sockets) lose efficacy, and can bring the trouble that needs the telephone terminal additional wiring, also can extra-pay occur because of additional wiring.

Therefore, the objective of the invention is for the ADSL transmission system provides a kind of PSTN jockey with separation equipment, this device is convenient to install and can save mounting cost.

To achieve these goals, the present invention provides a kind of PSTN jockey with separation equipment for the ADSL transmission system.This PSTN jockey comprises a telephone connecting device, and the telephone terminal separation equipment that telephone terminal can be connected to PSTN is equipped with in its inside, and an ATU-R jockey, and the ATU-R separation equipment that ATU-R is connected to PSTN is equipped with in its inside.This telephone connecting device is a telephone jack (jack) or telephone socket (socket), and the ATU-R jockey is an ATU-R socket or ATU-R socket.

Below want the most preferred embodiment that present invention will be described in detail with reference to the accompanying,, represent components identical with identical label in the accompanying drawings for the ease of understanding.Although schematically explain and illustrated specific embodiment in detail in order to illustrate theme of the present invention in this article,, even there are not these details, those skilled in the art still can explanation according to the present invention realize the present invention.In addition, omitted unnecessary detailed description in this article to the function and the structure of well-known.

Fig. 2 is the block diagram according to an ATU-R separation equipment 200 of most preferred embodiment of the present invention.ATU-R separation equipment 200 is blocked by DC and high-pass filtering part 202 constitutes, and is used for blocking the DC composition of the signal that receives from PSTN, and the DC block signal is carried out high-pass filtering.Signal through high-pass filtering is provided for ATU-R.

ATU-R separation equipment 200 can be contained in the socket 204 shown in Figure 3.If socket 204 is connected on the common socket that is coupled with PSTN, PSTN just need be connected to splicing ear C, and splicing ear C then is connected to ATU-R by ATU-R separation equipment 200.Therefore, handle signal, provide it to ATU-R then from PSTN with ATU-R separation equipment 200.

Or ATU-R separation equipment 200 can be contained in the socket 206 shown in Fig. 4.In this case, the terminal that is located at socket 206 bottoms that ATU-R separation equipment 200 is housed can be inserted into the common socket that is connected to PSTN, and can be located at a conventional jack insertion that is connected to ATU-R in the hole on its top.So just can handle signal, and then offer ATU-R with being contained in ATU-R separation equipments 200 in the socket 206 from PSTN.

Fig. 5 represents the block diagram according to a telephone terminal separation equipment 208 of most preferred embodiment of the present invention.Telephone terminal separation equipment 208 comprises low pass filter 210 and mark 212, carries out low-pass filtering with 210 pairs of signals from PSTN of low pass filter, offers telephone terminal by mark 212 then.Mark 212 provides various single-tones for telephone terminal.

Can be with a socket 214 shown in telephone terminal separation equipment 208 load maps 6.If socket 214 is connected on the common socket that is coupled with PSTN, PSTN just need be connected to splicing ear C1, and splicing ear C1 then is connected to telephone terminal by telephone terminal separation equipment 208.So just can handle signal, and then offer telephone terminal with telephone terminal separation equipment 208 from PSTN.

Or telephone terminal separation equipment 208 can be contained in the socket 216 shown in Fig. 7.In this case, the terminal that is located at socket 216 bottoms that telephone terminal separation equipment 208 is housed can be inserted into the common socket that is connected to PSTN, and can be located at the insertion of the conventional jack of telephone terminal in the hole on its top.So just can handle signal, and then offer telephone terminal with being contained in telephone terminal separation equipments 208 in the socket 216 from PSTN.

As mentioned above, PSTN jockey of the present invention has independently telephone terminal separation equipment or ATU-R separation equipment, and socket or socket that the telephone terminal separation equipment is packed into and is connected to telephone terminal, so that handle signal with the telephone terminal separation equipment, and then offer telephone terminal from PSTN.In addition, the ATU-R separation equipment is installed in the socket or socket that is connected to ATU-R, so that handle signal from PSTN with the ATU-R separation equipment, and then offers ATU-R.So just can optionally change the position of telephone terminal and ATU-R, the while keeps in residential housing and is used to connect the existing wiring of PSTN to telephone terminal.

The telephone terminal separation equipment can be contained in the shape identical socket or socket with the ATU-R separation equipment.Therefore, for convenience, the socket that the telephone terminal separation equipment is equipped with in inside has different colors with socket with inner socket and the socket that the ATU-R separation equipment is housed.In addition, can make the sign of the separation equipment kind of dress in the expression at various sockets and socket outside.

Although hereinbefore with reference to description of drawings illustrative examples of the present invention, the present invention obviously is not subject to these specific embodiments, and those skilled in the art can also realize various other change and modifications under the condition that does not break away from the spirit and scope of the present invention.
