Abstract

DC60 (02/09/54) Separation Device for Data and Telephone Applications (True Net Pass) is a circuit. Electronics of the phone Part of the work consists of equipment (Hardware) separates the telephone signal (Voice) and data (DATA) apart, while reducing signal interference. That came from the phone signal Fit into the corresponding circuit Where the phone signal sounds Will use the frequency band at 0 KHz.-10 KHz. While the data system uses the frequency signal from 30 KHz to 2.2 MHz, which decouters the use of data and telephones N (True Net Pass) this has important components. Work on the low-frequency (Low-Pass Filter) pass, but not high frequency of data (DATA) through and in the transmission signal with high frequency (High -Pass Filter) has electronic devices. S Assembled in the circuit so that the data signal is a frequency from 30 KHz to 2.2 MHz pass, but the low frequency of the voice (Voice) can not pass. Can be used more in the service Telephone network customers In order to enhance the full service capability of the telephone signal, a Ture Net Pass is installed between the Cross Connection Cabinet or CAB and in the In order to provide services to network applicants, True Net Pass (True Net Pass) equipment was created. From the application of electrical science and electronics in relation to the features of the equipment Together, this technology can be used to develop fixed-line network equipment as well. Separate devices for data usage and telephone use (True Net Pass) are cyclical. Electronics of the phone Part of the work consists of equipment (Hardware) separates the telephone signal (Voice) and data (DATA) apart, while reducing signal interference. That came from the phone signal Fit together according to the related circuit Where the phone signal sound It uses the O KHZ-10 KHz frequency band, while the data system uses the frequency signal from 30 KHz to 2.2 MHz. This decoder, data usage, and telephone (True Net Pass) are essential components that work in The low frequency (Low-Pass Filter) can pass but not high frequency of data (DATA) through and in the transmission signal with high frequency (High-Pass Filter) has electronic devices. Assembled in the circuit to provide data signals that are frequency from 30 KHz to 2.2 MHz, but the low frequency of the voice (Voice) can not pass. Used in addition to the service Customers of the telephone network To increase the ability to use the service of telephone signals to the fullest by a Ture Net Pass, a separate device for data usage and telephone (Ture Net Pass) installed in between the Coss connection Cabinet or CAB In accordance with the needs of the current usage in order to provide the service, the network applicant, the True Net Pass, was developed. From the application of electrical science and electronics in relation to the features of the equipment Together, this technology can be used to develop basic telephone network equipment.

Claims (5)

1. Telephone Line Splitter Applications Have characteristics Telephone receiver section (1) to connect to the noise reduction input (2) and output the signal output. The noise reduction (2) is connected to the input of the high-altitude control (3) and the low-frequency control (4) that are connected in parallel. There is a unique The Altitude Control (3) has a hardware (C, L, R) electronic device with two C current capacitors C 0.068 uF / 250 V in parallel and transmitting. Continue to The L-coil frequency filter has a value between L 14 m L .. and L 16 m H. per series between the output side of the two capacitors C, which the L coil has a specific frequency control function. The frequency signal is the data (Data) through (High-Pass Filter) and the output of the signal from each capacitor C current to the signal through a resistor R has a value of R10, 0.5 W. 5%. That are connected in parallel in a circuit Before exporting the end of the data signal (DATA) in which the electronic device The high-altitude control circuit is assembled and correlated, and it flows through the transmission channel portion, is used as data (5) to provide customers with data-only (DATA) applications. 2. A telephone line splitter device in accordance with item 1 in which the low frequency control (4) receives a separate signal passed from the noise reduction (2) and is connected in parallel with the high frequency control circuit (3) transmitted through the connection. With the input of the low-frequency control signal (4), there are two L-coil electronic devices (Hardware) L 14 mH to L 16 mH connected in parallel to prevent If the frequency exceeds 10 KH z. Pass the signal output to the capacitor C with a value of C0.068 uF / 250 V to make the signal higher than 10 KH z. Passed into the system to be lost and continue. The signal passes to the resistance R has a value of R10, 0.5 W .5% two paralleled before outputting the audio-only signal to the audio receiver. 3. Deactivates The use of telephone lines according to item 1, which is within the separation equipment. Simple operation signal, one unit system Includes a circuit to reduce noise. Signal of data through a telephone line And a separate telephone data signal circuit with the voice (voice) and the data (DATA) are connected in parallel that is transmitted through a telephone line pair sent together in telephone line To act to reduce interference and to separate the data signal (Data) from the voice (Voice) and to prevent short circuit of the transmission system in the phone use. 4. Dissection Devices Telephone line applications in accordance with clause 1-3, which are at least installed at the short-pair splitter (DP) or distribution box (CAB) that pays the customer on which part of the telephone line. Part one 5. Telephone line splitters in accordance with clause 1-3, which are installed at the branch intersection (DC) and coaxial distribution (CAB) that provide service to the customer according to the telephone line.
