Embodiment one：

In order to which solve that wiring route present in existing wiring method is excessive, difficulty is larger and cost is higher etc. asks Topic, the embodiment of the present invention one provide a kind of wiring method, as shown in Fig. 2, it is one kind described in the embodiment of the present invention one The flow diagram of wiring method, specifically, the method may include following steps：

Step 201：Determine the type for the signal for needing to be transmitted in a cable, however, it is determined that needs only pass in the cable Transmission of electricity source signal and network signal, then follow the steps 202, however, it is determined that needs only transmit telephone signal and network letter in the cable Number, then follow the steps 203, however, it is determined that need to transmit power supply signal, telephone signal and network signal in the cable, then execute step Rapid 204；

Step 202：According to one-to-one relationship, power supply signal the be added to M of a cable in the roads M transmits core wire In network signal so that power supply signal and network signal form integrated signal；Wherein, the M is positive integer, and the M Logarithm of the value no more than the core wire of the cable；

Step 203：According to one-to-one relationship, telephone signal the be added to N of the cable in the roads N transmits core wire In network signal so that telephone signal and network signal form integrated signal；Wherein, the N is positive integer, and the N Logarithm of the value no more than the core wire of the cable；

Step 204：According to one-to-one relationship, power supply signal the be added to M of the cable in the roads M transmits core wire In network signal, and, according to one-to-one relationship, the roads N telephone signal is added to the net that the N of the cable transmits core wire In network signal so that power supply signal, telephone signal and network signal form integrated signal；

Step 205：Pass through integrated signal described in the network cable transmission.

That is, power supply signal and/or telephone signal can be integrated into a cable and transmitted according to actual conditions Network signal in, integrated signal is formed, and by integrated signal described in the network cable transmission, to solve existing wiring side The problem of wiring route existing for method is excessive, difficulty is larger and cost is higher etc., greatly reduce network layout complexity, Reduce network wiring cost.

Optionally, due to universal, most of PC (personal computer, the personal electricity with Gigabit Ethernet Brain) it has all been configured with the network interface card of gigabit, therefore, gigabit network signal gradually becomes mainstream demand.Thus, in this hair In the bright embodiment, it is preferable that the network signal can be gigabit ethernet signal.Further, due to transmission gigabit letter Number minimum requirements be CAT5 (surpassing 5 class lines) cable (the transmission maximum distance of its signal can be 100m), which shares 8 cores Line, a pair of of differential signal can be transmitted two-by-two by mutually twisting, thus, when the network signal is gigabit ethernet signal, the cable It generally can be the cable for having 4 pairs of core wires, such as CAT5 (surpassing 5 class lines) cable.

It follows that transmitting power supply signal based on CAT5 cables etc. or when telephone signal, the power supply signal of transmission or The way of person's telephone signal at most can be 4 tunnels.That is, can at most transmit 4 road power supply signals, No. 4 phone letters in a CAT5 cable Number, this is not repeated.

Specifically, according to one-to-one relationship, power supply signal the be added to M of a cable in the roads M transmits core wire In network signal so that power supply signal and network signal form integrated signal, it may include：

If desired the transmission of one line power supply signal in a cable, then can be added to the power supply signal all the way the cable Any pair of core wire in；Alternatively, if desired transmitting power supply signal at least all the way in the cable, you can first from the cable In all core wires, select at least a pair of of core wire (it is selected go out core wire logarithm and the power supply signal that need to be transmitted way phase Together), and according to one-to-one relationship, by the power supply signal at least all the way be added to it is selected go out at least a pair of of core wire In.

It should be noted that at this point, for any pair of core wire in the cable, power supply letter can have only been transmitted Number and network signal, also can only transmit network signal, this has not been limited in any way.

Similarly, according to one-to-one relationship, telephone signal the be added to N of the cable in the roads N transmits core wire In network signal so that telephone signal and network signal form integrated signal, it may include：

If desired the transmission of one line telephone signal in a cable, then can be added to the telephone signal all the way the cable Any pair of core wire in；Alternatively, if desired transmitting telephone signal at least all the way in the cable, you can first from the cable In all core wires, select at least a pair of of core wire (it is selected go out core wire logarithm and the power supply signal that need to be transmitted way phase Together), and according to one-to-one relationship, by the telephone signal at least all the way be added to it is selected go out at least a pair of of core wire In.

It should be noted that at this point, for any pair of core wire in the cable, phone letter can have only been transmitted Number and network signal, also can only transmit network signal, this has not been limited in any way.

Further, if needing simultaneous transmission power supply signal, telephone signal and network signal in a cable, only Power supply signal and telephone signal need to be superimposed upon in the network signal that a cable is transmitted i.e. respectively according to above-mentioned stacked system Can, i.e., the roads M power supply signal can be specifically added to the network that the M of the cable transmits core wire according to one-to-one relationship In signal, and, according to one-to-one relationship, telephone signal the be added to networks that are transmitted to core wire of N of the cable in the roads N are believed In number so that power supply signal, telephone signal and network signal form integrated signal；And power supply signal and telephone signal are superimposed Order can be not fixed.That is, can power supply signal be first added to corresponding core wire in cable in the network signal that is transmitted, then will Telephone signal is added to corresponding core wire in the cable in the network signal that is transmitted, also first telephone signal can be added to Corresponding core wire is in the network signal that is transmitted in the cable, then power supply signal is added to corresponding core in the cable Line is not in the network signal that is transmitted, being limited in any way this.

Further, it should be noted that when according to above-mentioned stacked system, being respectively superimposed power supply signal with telephone signal When in the network signal that a cable is transmitted, for any pair of core wire in the cable, electricity can have been transmitted Source signal, telephone signal and network signal also can only transmit power supply signal and network signal, or only transmission has phone Signal and network signal, or even network signal can have also only been transmitted, this is not limited in any way.

In the following, by how power supply signal all the way being added in the network signal that a pair of of core wire is transmitted, or how Telephone signal all the way is added in the network signal that a pair of of core wire is transmitted, or how will power supply signal, electric all the way all the way Three kinds of situations in the network signal that words Signal averaging is transmitted to a pair of of core wire are specifically described.

Specifically, the first stacked system as shown in Figure 3 will be folded power supply signal all the way it is found that for any to core wire It is added in the network signal transmitted to core wire, specifically can perform and be：

By the first inductance for being connected with first core wire (core wire 1 as shown in Figure 3) to core wire (such as institute in Fig. 3 The L1 shown), it power supply signal will be added to all the way (such as DC15V etc.) in the network signal transmitted to core wire, so that this is right Transmission has power supply signal and network signal in core wire.

Further, second of stacked system as shown in Figure 3 be it is found that for any to core wire, will power supply signal all the way It is added in the network signal transmitted to core wire, specifically can perform and be：

By the second inductance for being connected with first core wire (core wire 1 as shown in Figure 3) to core wire (such as institute in Fig. 3 The L2 shown) and the third inductance that is connected with second core wire (core wire 2 as shown in Figure 3) to core wire (such as institute in Fig. 3 The L3 shown), telephone signal all the way is added in the network signal transmitted to core wire, so that this has transmission in core wire Telephone signal and network signal.

Further, the third stacked system as shown in Figure 3 is it is found that for any to core wire, will all the way power supply signal, And telephone signal is added in the network signal transmitted to core wire all the way, specifically can perform and is：

By the first inductance for being connected with first core wire (core wire 1 as shown in Figure 3) to core wire (such as institute in Fig. 3 The L1 shown), power supply signal all the way is added in the network signal transmitted to core wire, and by with this to core wire first Connected the second inductance (L2 as shown in Figure 3) of core wire (core wire 1 as shown in Figure 3) and with this to the second of core wire The connected third inductance (L3 as shown in Figure 3) of core wire (core wire 2 as shown in Figure 3), telephone signal will be added to all the way In the network signal transmitted to core wire.

Further, it should be noted that for any to core wire, be superimposed with when in the network signal that needs are transmitted to it Corresponding telephone signal, and when being mingled with AC signal in the telephone signal, it can be first by corresponding to core wire with this The telephone signal rectification is direct current signal by rectifier circuit, and then passes through the first output positioned at the rectifier circuit The second inductance between end and first core wire to core wire and positioned at the rectifier circuit second output terminal with this to core The direct current signal is added in the network signal transmitted to core wire by the third inductance between the second core wire of line.

Wherein, the rectifier circuit can be the existing rectifier circuit for having arbitrary structures, as long as it can will be with It is direct current signal that its corresponding a pair of of core wire, which needs the telephone signal rectification for being mingled with AC signal transmitted,.For example, its Can four diodes (D1, D2, D3, D4) shown in the stacked system of the third in Fig. 3 form；Certainly, can also have it His circuit structure, details are not described herein again.

That is, being mingled with the telephone signal of AC signal, determined just after rectifier circuit rectification, becoming Pole, cathode a direct current signal, and the core wire 1 of cable is linked into, on core wire 2 by inductance L2, L3.

In addition, it is necessary to explanation, in order to be effectively prevented from the decaying of network signal, described L1, L2, L3 etc. can be height The inductance of frequency high impedance low frequency almost no resistance, does not repeat this.

Further more, it should be noted that being superimposed the situation of telephone signal in the network signal transmitted to cable for needs For, it is another if it is not to be mingled with the telephone signal of AC signal that a pair of of core wire in the cable, which needs the telephone signal transmitted, When to need the telephone signal transmitted be the telephone signal for being mingled with AC signal to core wire, the telephone signal of AC signal it is not mingled with It can be directly added in corresponding a pair of of core wire by L2, L3, be mingled with the telephone signal of AC signal, can first pass through whole Then the rectification of current circuit is added to by L2, L3 in corresponding a pair of of core wire again.That is, at this point, can be according to need The characteristics of telephone signal to be superimposed, can correspond to difference in a piece cable to select corresponding stacked system per a pair of of core wire Stacked system, the embodiment of the present invention is not limited in any way this.

Further, there is every a pair of of core wire of telephone signal and network signal in the cable, simultaneous transmission (such as simultaneous transmission has every a pair of of core wire of power supply signal, telephone signal and network signal, alternatively, only simultaneous transmission has phone Every a pair of of core wire of signal and network signal), it can also be by micro- to detect to the corresponding off-hook detection circuit of core wire with this The real-time status of exchange termination side telephone terminal, such as off hook state or hook state.

Specifically, as shown in the third stacked system in Fig. 3, believe for simultaneous transmission telephone signal and network is needed Number a pair of of core wire, can be by flowing through this to the electric current in core wire to the corresponding off-hook detection circuit of core wire to detect with this Size, and according to the size for flowing through the electric current to core wire detected, judge with this be to the corresponding telephone terminal of core wire It is no to be in off hook state.

Optionally, as shown in the third stacked system in Fig. 3, there is times of telephone signal and network signal for transmission A pair of of core wire of meaning, with this to the corresponding phone off-hook detection circuit of core wire may include first resistor (R1 as shown in Figure 3), First capacitance (C1 as shown in Figure 3), first comparator (comparator 1 as shown in Figure 3), the first transistor are (in such as Fig. 3 Shown in Q1), second resistance (R2 as shown in Figure 3), 3rd resistor (R3 as shown in Figure 3) and the second capacitance is (such as C2 shown in Fig. 3) etc., wherein：

Wherein, more mouth switchs in micro- exchange termination (are networked in addition to that can have Z second line of a couplet network interface under such as gigabit Mouthful) to be provided except corresponding ethernet signal to Z station, can also have 1 first line of a couplet network interface (such as gigabit first line of a couplet network interface), with The network signal of desampler side transmission.

In addition, it is necessary to explanation, micro- exchange termination (concretely more oral sexes in micro- exchange termination Change planes) power supply in addition to that can be from corresponding core wire to being isolated in the signal that is transmitted for micro- exchanges end Can be also any other external power supply, details are not described herein again except the power supply signal for holding power supply.Further more, it should be noted that When the power supply of micro- exchange termination (concretely more mouth switchs in micro- exchange termination) is from corresponding Core wire to isolated in the signal that is transmitted the power supply signal for powering to micro- exchange termination when, be micro- friendship The core wire of terminal of changing planes offer power supply signal is certainly or multipair to generally can be a pair, does not also repeat herein.

It further, specifically can be in the following manner for by the integrated signal after telephone signal and network signal aggregation Carry out the separation of the integrated signal：

Every a pair of of the core wire for having telephone signal and network signal for the only simultaneous transmission of the cable, in Fig. 3 Shown in second of separate mode, can by the L4 that is connected with first core wire to core wire and with second core to core wire The connected L5 of line, isolates telephone signal all the way, to obtain the roads N telephone signal from the signal transmitted to core wire；And According to the second line of a couplet network interface number of micro- exchange termination, the network signal that the cable is transmitted is converted into Z road networks road signal.

It optionally, can be when the phone letter transmitted per a pair of of core wire in the cable when carrying out the separation of signal After number being separated, using remaining signal in the integrated signal as network signal all the way, and according to micro- friendship The second line of a couplet network interface number (the concretely second line of a couplet network interface numbers of more mouth switchs in micro- exchange termination) for changing terminal, by the cable The network signal transmitted is converted to Z road networks road signal (such as 4 tunnels), in order to which Z station (such as Z platform PC) is used.Certainly, Also it can be carried out at the same time the separation of network signal and telephone signal etc., alternatively, the separation for first carrying out network signal carries out phone again The separation of signal, does not repeat herein.

It should be noted that at this point, due in the cable only transmission have telephone signal and network signal, thus, be Micro- exchange termination and the power supply of corresponding telephone terminal power supply can be arbitrary external power supply, and details are not described herein again.

Further, for by the integrated signal after power supply signal, telephone signal and network signal aggregation, can specifically lead to Cross the separation that following manner carries out the integrated signal：

According to the second line of a couplet network interface number of micro- exchange termination, the network signal that the cable is transmitted is converted into Z road networks Road signal；And

Every a pair of of the core wire for having power supply signal and network signal for the only simultaneous transmission of the cable, by right with this The 4th inductance first core wire of core wire connected third inductance and be connected with second core wire to core wire, from this to core The power supply signal for being used to power to telephone terminal all the way is isolated in the signal that line is transmitted, and, however, it is determined that this is to core wire institute The power supply signal of transmission also needs to power to the micro- exchange termination, then also by be connected with first core wire to core wire the Six inductance and the 7th inductance being connected with second core wire to core wire, are isolated from the signal transmitted to core wire The power supply signal for being used to power to micro- exchange termination all the way (for details, reference can be made to the first separate modes shown in Fig. 3)；Or Person,

Every a pair of of the core wire for having telephone signal and network signal for the only simultaneous transmission of the cable, by right with this The 4th inductance first core wire of core wire connected third inductance and be connected with second core wire to core wire, from this to core Telephone signal all the way is isolated in the signal that line is transmitted (for details, reference can be made to second of separate modes shown in Fig. 3)；Alternatively,

Transmission has every a pair of of core wire of power supply signal, telephone signal and network signal while for the cable, leads to The third inductance being connected with first core wire to core wire and the 4th inductance being connected with second core wire to core wire are crossed, Isolated from the signal transmitted to core wire be mixed with all the way be used for all the way the power supply signal powered to telephone terminal and The mixed signal of telephone signal all the way, and, however, it is determined that the power supply signal transmitted to core wire is also needed to micro- exchange Terminal is powered, then also by the 6th inductance that is connected with first core wire to core wire and with second core wire to core wire The 7th connected inductance isolates the electricity for being used for powering all the way to micro- exchange termination from the signal transmitted to core wire Source signal (for details, reference can be made to the third separate modes shown in Fig. 3).

It optionally, can be when the power supply letter transmitted per a pair of of core wire in the cable when carrying out the separation of signal Number and after telephone signal is separated, using remaining signal in the integrated signal as network signal all the way, and According to second line of a couplet network interface number (the concretely second line of a couplet network interface of more mouth switchs in micro- exchange termination of micro- exchange termination Number), the network signal that the cable is transmitted is converted into Z road networks road signal (such as 4 tunnels), in order to Z station (such as Z platforms PC etc.) it uses.Certainly, it can be also carried out at the same time the separation of network signal, telephone signal and power supply signal etc., alternatively, first carrying out The separation of network signal carries out the separation of power supply signal, telephone signal again, does not repeat herein.

That is, in embodiment of the present invention, micro- exchange termination can receive interchanger and pass through a network cable transmission Integrated signal, and the integrated signal is separated into corresponding power supply signal and network signal, or, telephone signal and network letter Number or power supply signal, telephone signal and network signal, to solve wiring route existing for existing wiring method it is excessive, The problem of difficulty is larger and cost is higher equal, greatly reduces the complexity of network layout, reduces network wiring cost.

Further, since telephone terminal is a low power consuming devices, the electric current needed is tens milliamperes, the confession for distal end Electric end is it is difficult to judge whether there is off-hook or be very easy to judge by accident, it is therefore desirable to amplify the operating current after off-hook.That is, In order to enable the off-hook hook state of telephone terminal is learnt in opposite end, i.e. interchanger, there is electricity in the cable, simultaneous transmission Every a pair of of the core wire for talking about signal and network signal, off hook state is in determining with this to the corresponding telephone terminal of core wire When, can also by with this to the corresponding off-hook start-up circuit of core wire, extracurrent is inputted to core wire to this so that right with this When the corresponding telephone terminal of core wire is in off hook state, flow through the electric current to core wire be more than with this to the corresponding electricity of core wire When telephone terminal is in hook state, the electric current to core wire is flowed through.

Wherein, it should be noted that it can be only to transmit to core wire that simultaneous transmission, which has this of telephone signal and network signal, There are a pair of of the core wire or simultaneous transmission of telephone signal and network signal to have power supply signal, telephone signal and network letter Number a pair of of core wire, the embodiment of the present invention do not repeat this.

Specifically, right with this as shown in figure 3, there is any pair of core wire of telephone signal and network signal for transmission The corresponding phone off-hook start-up circuit of core wire may include second transistor (Q2 as shown in Figure 3), the 4th resistance (such as Fig. 3 Shown in R4), the 5th resistance (R5 as shown in Figure 3) and the second comparator (comparator 2 as shown in Figure 3), In：

The collector of the Q2 is connected by R4 with the first telephone signal output end to core wire, the emitter of the Q2 It is connected with the second telephone signal output end to core wire and the emitter of the Q2 is also connected by L5 with the second core wire；Its In, which passes sequentially through R5, L4 and is connected with the first core wire；And

The comparator 2 is connected in parallel on the both ends of the R5, and the base stage phase of the output end of the comparator 2 and the Q2 Even.

The circuit structure of phone off-hook start-up circuit as shown in Figure 3 is it is found that when telephone terminal (the third in such as Fig. 3 Shown in separate mode phone export) off-hook when, there is electric current to flow through L4 and R5, if the electric current is sufficiently large so that the both ends R5 Voltage difference be more than comparator 2 voltage detecting thresholding when, comparator 2 will export corresponding high level to Q2 so that Q2 be connected, At this point, there is electric current to flow through R4 so that the off-hook start-up circuit can input an extracurrent to a pair of of core wire corresponding to it, make When be in off hook state to the corresponding telephone terminal of core wire with this, flow through the electric current to core wire more than with this to core wire phase When corresponding telephone terminal is in hook state, the electric current to core wire is flowed through, so that exchanger side (or long-range phone Programme-controlled exchange) it telephone terminal can be determined is in off hook state.And when telephone terminal on-hook, no electric current flows through R5, Exchanger side is readily able to judge that telephone terminal is in hook state.

For example, by taking corresponding a pair of of the core wire of the third separate mode shown in Fig. 3 as an example, to phone off-hook start-up circuit It is further described.Assuming that more mouth switchs in micro- exchange termination are 5 mouth switchs at this time, due to general 5 mouth switch Power consumption in 2W or so, need 200 milliamperes of 12VDC power supplys.Thus, micro- exchange termination can be obtained by this to core wire The voltage of 12V or so, to provide corresponding working power for internal 5 mouth switchs power supply and for telephone terminal, in Fig. 3 " output of POE power supplys " shown in the third separate mode is to power to 5 mouth switchs, and " power supply output " is to telephone terminal Power supply.

Correspondingly, when phone off-hook, 12VDC power supplys will pass through inductance L4, R5 (usually several ohms, such as 5 ohm Left and right), tens milliamperes of electric current is provided to telephone terminal, then it is also tens milliamperes to flow through the electric current on R5, such as 30 milliamperes, this Sample just has 150 millivolts of voltage difference or more at the both ends R5, meets or exceeds the voltage detecting thresholding (such as 150 millivolts) of comparator 2, because This, 2 exportable high level of comparator so that Q2 is connected, meanwhile, R4 (generally can be hundreds of Europe) can be increased in circuit The electric current of Q2 is flowed through in limitation, if R4 values are 100 Europe, then flowing through the electric current of Q2 about at 100 milliamperes or so so that work as phone When terminal is in off hook state, 12VDC power supplys can provide 300 milliamperes of electric current to micro- exchange termination side, at telephone terminal When hook state, 12VDC power supplys can provide 200 milliamperes of electric current to micro- exchange termination.That is, in telephone terminal off-hook and extension When machine, flowing through the electric current to core wire, there are the difference of 100 milliamperes of electric currents, and the electricity of micro- exchange termination side is detected convenient for exchanger side Telephone terminal whether off-hook.

By experiments have shown that, under original 200 milliamperes of electric current, increase by 100 milliamperes of electric current, for being distally to be easy to sentence Disconnected curent change, there can't be the case where erroneous judgement, thus, it may make interchanger (or long-range telephone exchanger) energy Whether the telephone terminal for enough more precisely detecting micro- exchange termination is in off hook state.

Further, as shown in figure 3, in distant-end switch side, 15VDC power supplys can pass through inductance L1, L2 access of high frequency To cable, while also passing through R1 (being usually several Europe or so, such as 0.5 Europe).If only changed to 5 oral sexes in micro- exchange termination Machine is powered, then the electric current for flowing through R1 is about 200 milliamperes, at this point, the voltage at the both ends R1 can be 100 millivolts, there are no reach The detection voltage threshold (such as 150 millivolts) of comparator 1, therefore, comparator 1 export low level, and Q1 is in cut-off state, without electricity Stream flows through DC load circuit, i.e. DC load circuit does not work, and telephone input is not with any DC load.And work as (i.e. telephone terminal off-hook when 15VDC power supplys need 5 mouth switchs into micro- exchange termination and corresponding telephone terminal to power When), then by the above-mentioned description for micro- exchange termination it is found that flow through the current-variable of R1 into 300 milliamperes, and then the electricity at the both ends R1 Piezoelectricity pressure difference is 150 millivolts or so, has reached the voltage detecting thresholding of comparator 1 so that comparator 1 exports high level, and Q1 is led It is logical, there is electric current to flow through DC load circuit, i.e. phone inputs one DC load of both ends band so that interchanger determines micro- friendship Change the corresponding telephone terminal off-hook in end side.

Wherein, the resistance value of R2, R3 can be hundreds of ohm, such as 200~300 Ω；The capacitance of C2 can be 2 μ F etc..It needs It is noted that for AC signal, C2 is equivalent to short circuit, therefore for AC signal Q1 in cut-off state, therefore, The AC signal that can avoid being mingled in telephone signal attenuates in DC load.In addition, it is necessary to explanation, C3, C4, C5, The value of C6 can be 0.01 μ F etc., and details are not described herein again.

Further more, it should be noted that in order to be effectively prevented from the decaying of network signal and to power supply signal and phone The separation and extraction of signal, described L4, L5, L6 and L7 etc. can be the inductance of high frequency high impedance low frequency almost no resistance, right This is not repeated.

Further, inside in order to avoid telephone signal and/or power supply signal string to micro- exchange termination, for the cable Per a pair of of core wire, can also be by the 5th capacitance that is arranged in the first core wire (core wire 1 as shown in Figure 3) at this to core wire (C5 as shown in Figure 3) and the 6th electricity being arranged in the second core wire (core wire 2 as shown in Figure 3) at this to core wire Hold (C6 as shown in Figure 3), the telephone signal and/or power supply signal transmitted to core wire to this are isolated (for network Signal, C5, C6 are equivalent to short circuit, and for telephone signal and/or power supply signal, C5, C6 are equivalent to open circuit), to reduce this to core Telephone signal that line is transmitted and/or power supply signal to the interference caused by micro- exchange termination, that is, avoid telephone signal and/ Or inside power supply signal string to micro- exchange termination.

Further, it should be noted that the telephone terminal described in the embodiment of the present invention can be traditional telephone, The telephone terminal has is converted to electronic signal by the sound wave of terminal, is transmitted to remote other side by telephone wire, simultaneously The electronic signal that other side's transmission comes is regenerated as voice (sound wave), the call function with remote other side is realized, in addition, it may be used also Corresponding signal (dial impulse) is selected from multiple other side, notifies other side using functions such as calling tones, details are not described herein again.

Second embodiment of the present invention provides a kind of using micro- exchange termination as the wiring method of executive agent, and micro- exchange termination can The integrated signal is separated into corresponding power supply signal and net by desampler by the integrated signal of a network cable transmission Network signal, or, telephone signal and network signal or power supply signal, telephone signal and network signal, to solve existing cloth The problem of wiring route existing for line method is excessive, difficulty is larger and cost is higher etc., greatly reduces answering for network layout Polygamy reduces network wiring cost.
