TW466864B - System for multiple voice lines with data over a single subscriber loop - Google Patents

Abstract

A system that provides additional voice lines with data over a single two-wire subscriber loop. At the subscriber premise, one or more telephone instruments and data devices are connected to a digital modem into either a voice or a data interface. Analog voice signals are PCM sampled then packetized, and voice and data packets are transmitted to a CO modem over the subscriber loop. The CO modem depacketizes the voice packets into PCM format and transmits PCM voice information to a CO switch over a standard digital trunk interface. Data packets are routed to a data network. Voice packets are given transmission priority over data packets to ensures that voice is transported in the presence of data with low latency.

Description

A7 466864 ______B7_______ V. Description of the Invention (1) Field of the Invention-The present invention is related to digital subscriber loop applications', especially to multiple data voice lines sharing a single subscriber loop. BACKGROUND OF THE INVENTION · With the popularity of the Internet and the growing number of small businesses at home, telephone service providers are increasingly demanded by businesses and homes to add voice line services. Most central computer rooms have additional switching capacity that provides additional voice lines to the client. Once the additional access line is extended to the subscriber, the telephone service provider only needs to pay a small fee to provide voice services, but the services provided by the additional line can increase the profit of the telephone service provider. The traditional method of providing additional access lines is to lay copper wires to the client and add or change the lightning protection device at the client to increase the analog user response. The so-called user circuit is the dual copper wire transmission path and signaling path between the telephone user terminal equipment and the service central computer room (or other terminal equipment). However, the time and cost involved in this method is huge, and the time consumption will reduce the investment profit. From a transmission point of view, any analog user loop-based signal system has problems with signal loss and signal damage. This situation is caused by physical conditions, such as bridge taps, changes in wire diameter, line length, insulation, aging, and damage to environmental cables, or from external sources such as pulse noise and audio Caused by interference. The so-called signal decay is generally noise, loss, loss, and interference. -4-This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm), --- ^ -------- '.

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs and printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs and printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Another problem with the traditional method is that analog modems generally use standard modems, and standard modems use the baseband POTS (basic telephone service) voice spectrum (0-4 Hz) to transmit information. The sound effect and transmission power of the pair must not exceed the level specified by the Federal Communications Commission. At present, the Federal Communications Commission stipulates that the output speed of the service provider's modem should be limited to 53,000 bits per second, and the upload speed should be limited to 31,200 bits per second. Actual speed may vary depending on line conditions, but this limit cannot be exceeded. Frequency division multiplexing (FDM) is a technology that can provide additional voice lines on the user circuit without the need for additional copper wires. The spectrum used by this method is separated from the spectrum used by the fundamental frequency POTS, which allows us to use the higher frequency of the additional 4 仟 Hz analogy POTS channel on the same two-line user loop. Carrier. However, this band-frequency analog carrier technology will cause the analog loop to suffer more signal loss and greater signal damage than traditional methods. Digital line doubling (DAML) is a technology that belongs to FDM. At the office and y-side, a DAML modem will supply two or more user loop digital signals for use. The modem converts these analog voice signals into a digital line code format, and then transmits it through a single user loop to another DAML modem located at the client (or near the client). The DAML data of the client will decode the line code to provide the user with two or more two-line connections corresponding to the user loop connected to the central DAML modem. There are many forms of codes that can be used as this digital line code. The most commonly used forms are amplitude, phase, and frequency key shifts, 2-2 bits-1 bit, and no carrier amplitude.

Description of the invention (3) and phase modulation and quadrature amplitude phase modulation. The problem with this method is the digital / analog / digital conversion performed by V at the central office from the blog code modulation (pcM) digital signal to an analog loop signal, and then from the analog loop signal back to the DAML digital signal. It will cause quantization error and phase misalignment, which will lead to the degradation of signal quality. Another technology that digitally transmits multiple voice lines over a subscriber loop is the Integrated Services Digital Network (ISDN). It is a system of multiple voice / data channels with virtual digits and signal channels. However, 1301 ^ needs to change the switching system equipment ’and the management and maintenance method of the switching system. Another method is to send voice packets over a data network that contains user circuits. This method is better known as transmitting voice over Internet Protocol (VOIP), transmitting voice over asynchronous transmission mode (VOATM), and transmitting voice over frame transfer (VOFR). VOIP—usually used in the campus environment. The wire used in each terminal is the EIA / TIA-570-91 standard published by the Electronics Industry Alliance / Telecommunications Industry Association in June 1991: "Home and Light Commercial Electricity "jj wire" type 5 wire or optical fiber; each terminal is connected to a universal switching structure 'like Ethernet, asynchronous transmission mode or hybrid system. In addition, through a gateway such as a router or a layer 3 switching system, the campus network can be called to bridge to the Internet or the corporate network. In some cases, desktop computers and other devices can be used as VOIP enabled terminals. We use enabled terminals to support compliance with the ITU-T standard published by the International Telecommunication Union (ITU) in February 1998.

Description of the invention (4) Remote communication of multimedia communication system. Such systems typically use digital signal processors (DSPs) on desktop computers to perform voice "packet compression," and then feed them to other workstations on the corporate intranet in the area or send them to remote locations via the Internet. V〇atm and VOFR are another decapsulation technology that uses the public switched telephone network (pSTN) to transmit voice and network connection. The user circuit can use the signal and transmission technology of the digital user circuit series to extend to the wide area network For V0IP applications. The technology of the digital user circuit series, the bandwidth sent to the client can co-exist with the baseband 卩 〇 for services. ISDN can also provide bandwidth to homes connected to the packetized network. Packetized network! ^! ^ Can also provide voice services. ISDN or digital user circuit technology (such as asymmetric digital user circuits and European high-speed digital user circuits) can also transmit 1? Packets on the user circuit, ATM cells or other frame formats. However, the basic requirements for voice and data are different for this web service. Voice transmission only needs to be small Bandwidth, but the supplied bandwidth must basically be dedicated or continuous with very little delay, delay variation, or loss. Even if the delay is in the range of milliseconds, it will produce a clear echo in the conversation. Intermittent. For example, delays caused by routers and gateways will adversely affect voice. Packetized voice belongs to the category of real-time traffic data, so the basic requirements for transmission of loss and error are very strict. In packet The average end-to-end transmission time of the network must be small, and the change of the end-to-end transmission time, including the loss problem, must also be small. -7- This paper standard is applicable to the Chinese National Standard (CNS ) A4 size (210 X 297 mm) II A 'Binding --------- line · (Please read the legal notice on the back before filling this page) 4 6 6 86 4' Μ 'Ministry of Economy Printed by A7 B7, Consumer Cooperatives of the Property Bureau. 5. Description of the invention (5) In the voice transmission, the overall delay should not exceed 2 (0) milliseconds, which is the acceptable number for commercialization. 100-200 milliseconds is general The goal pursued If the delay is around 800 milliseconds, it will prevent normal conversation. The normal state sinks down. For the delay of 200-800 milliseconds, if it occurs infrequently and occurs during a short call, it can be conditionally accepted. In the traditional voice network, the round-trip delay time is about 20-30 milliseconds. The voice delay in the frame transfer network can be about 125-20,0 milliseconds. The Ethernet network carries TCP / IP The delay time in the packet depends on the volume of the traffic. The range of its change is wider. Because the shared data network technology lacks the timeliness of the network, the above-mentioned delay requirements must be extended to users. It is a severe challenge to transmit voice in the general campus network environment. In addition, ATM as a standard still lacks support for voice compression, silence suppression, suppression of idle channel cells, and lack of support for signals that include converting voice signals to exchange virtual link ATM signals. In addition, because the AT delay network and the cell delay variation introduced by the cell combination / unpacking delay will be accumulated by the ATM repeater buffer used for narrowband services (such as voice services), except for the ATM network itself In addition to the resulting delay, the ATM repeater also introduces some additional delay. It is therefore an object of the present invention to provide a system that can provide additional voice and data lines on a user circuit shared with POTS. To this end, it is another object of the present invention to provide support for any in-band signal that supports advanced telephone characteristics. -8- This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) — — — — — 1 — --- — II Order -----] I JN ^ (Please read the Please fill in this page again for attention> 4 6 6 864 A7 __ B7 V.
