Abstract

A data transceiver having a simple configuration and being capable of reliably transmitting and receiving high-rate data to and from a counterpart at a remote site far apart from the transceiver over a telephone wire. The transceiver encodes a first data signal from a data equipment into a first encoded data signal to a counterpart transceiver through a telephone wire (50) and receives a second encoded data signal from the counterpart transceiver through the telephone wire (50) to provide a second data signal corresponding to the second encoded data signal to the data equipment. A 8B108 encoder (152) encodes the first data signal in a manner for reducing a magnitude of an accumulated DC component of the first data signal. A packetizer (146) encapsulates the first data signal having an Ethernet format. An equalizer (154) equalizes an encapsulated signal to reduce a magnitude of a transmit level of a second bit of two consecutive data bits of the same logical levels to a reduced level. A medium access controller (142) controls a medium access to facilitate a bidirectional data communication through the telephone wire (50).

Each 8-bit data is divided into the most efficient 5 bits and the least significant 3 bits, which are respectively encoded into a 6-bit and 4-bit code. The most efficient 5 bits are encoded according to encoding table I, and the least significant 3 bits are encoded according to an encoding table IIA or „B. The six-bit codewords in encoding table I are prepared as each The DC component of the codeword is minimized. Each four-bit codeword in the encoding table „A is prepared 'to have a slightly negative DC component, and each four-bit codeword in the encoding table IIB The element system is prepared to have a slightly positive DC component. As long as the least significant 3 bits are encoded, one of the encoding tables ΠA and ΠB is selected 'so that a cumulative direct current component (DCi) approaches zero. That is, when the cumulative DC component (DC 丨) is positive, the least significant 3 bits are encoded according to the encoding table ΠA ', but when the cumulative DC component (0 (: 0 is negative, it is encoded according to the encoding table llβ. Therefore, The cumulative DC component (DCi) is close to zero continuously. At the same time, this data processing obtains a result equivalent to a high-pass filtering operation to reduce the low-frequency components in the data signal and reduce the interference between the voice signal and the data signal. ^ 8B10B line coding process will be described in detail with reference to Figure 8.

Description of the invention () The bit data is divided into the most efficient 5 bits and the least significant 3 bits (step 2 5 0) 'and the most efficient 5 bits are encoded Becomes a six-bit code character, according to the encoding table 1 (step 252). The direct current component (DC) of the six-bit code character is added in step 254 The calculated and calculated DC component (DC) is added to the accumulated DC component to the final data transmission (DCi-i) to calculate the accumulated DC component to the current data transmission (DCi) in step 256. Then, it is decided whether to accumulate The DC component (DCi) is negative (step 258). When the cumulative DC component (DCi) is not negative in step 258, the least significant 3 bits are encoded as a four-bit code character (4B +) according to Table IIA (Step 26). If the cumulative direct current component (DCi) is negative in step 258, the least significant 3 bits are encoded as a four-bit code character (b-) according to Table IIB (step 262).

The decoding process performed by the 10B8B decoder 164 The system is as follows: Referring to Figure 9, the received data of the ten-bit TG is divided into the most efficient 6-bit and the least-efficient 4-bit (step 270), and the most efficient 6-bit is based on the table! It is decoded into 5-bit data (Step 272) The most efficient 6-bit direct current component (DC) of the received data is calculated in step 274 and calculated. The direct current component (DC) is added to the cumulative DC component to-the final data reception (DCi ^), in step 276, the cumulative DC component is calculated to an existing data reception ⑽. Then, it is determined whether the cumulative DC component ( DC0 is negative (step 278).

Generally speaking, the transmission characteristics of the electrical backup line affected by the error rate of the received data depend on the connection status of the envelope 'and the media characteristics of a transmission distance. The data received by the same temple "The error rate is affected by the balance level of the DC component. When most data bits with the same sign are transmitted sequentially, the DC component increases imbalance. In the present invention, the equalizer 154 reduces the imbalance of the DC component by adjusting the data level when the same negative sign (data bit 7C is transmitted sequentially). Furthermore, the equalizer 154 is based on the transmission of the telephone line. Characteristics, and then adjust the transmission level to ensure stable data transmission. As shown in Figure 10A, when a transmitted data bit has a sign that is different from the previous one, the equalization H 154 transmits the data bit data, Or -vpeak, when the data bits are "丨 ,, or ,, 0 ,,". As shown in Figure 1⑽, when the transmitted data bits have the same sign as the previous bit, the data bits are different.

It is used to transmit continuous zero or one τ fly <level amplitude (Vi) is less than Transmits the amplitude of the continuous zero or one level (Vpeak), therefore, the DC component of the signal carrying the continuous zero or one is reduced. As shown in Figure 10C, the transmission reliability is based on the transmission wheel level and distance. Therefore, it is better to 'transmit the vibration level of the continuous asset level (Vi) to The characteristics and transmission distance are determined. Because the sender's equalization 1 54 does not know the channel characteristics or transmission distance, so Λ 1 finds 12.5 million time-divider media printing.

Description of the invention (The body access controller 1 42 is sent through the equalizer i 54 for most tests The vector-to-receiver's test vectors have different levels from each other. The receiver's time-sharing media access controller 1 42 determines the channel characteristics based on the received test vector and returns the channel characteristic information. Therefore, the transmitting party can decide The level of the best transmission channel (Vi) ° When the encapsulation error in the received data increases beyond a certain criterion, preferably, the transmission level (Vi) is adjusted after the above sequence. Figure 10E illustrates equalization Example of the 8B10B line coded bit stream in figure iOD. On the other hand, the media access control between the center module 20 and the user module 74A is required because the information is transmitted in both directions via the telephone line. In the present invention, the two-way data transmission is completed by time division multiplexing, and the user module 74A controls the media access as a main unit. The media access control operation will be described with reference to Figures 1 A and 11B The diagrams are state transition diagrams, which respectively show the state transitions of the time-sharing media access controller 1 42 occurring in the user module 74A and the center module 20. Referring to FIG. 11A, the user module 74A exists in five types One of the possible states: a channel search state S10, a standby state S12, a receiving state S 1 4, a control packet transmission state S 1 6 and a data packet transmission state S 1 8.

Description of Invention (Various modifications can be made without departing from the spirit and basic characteristics of the invention. For example, although not shown in Figures 3 and 5, each digital modem 32 and 82 may contain a non- Volatile memory, such as an EEPROM or a flash memory, is used to store code for operating the time-sharing media access controller 142 and retransmission controller 144. In addition, the digital modems 32 and 82 may additionally include a volatile Memory, such as DRAM. DRAM can complete the decapsulation and decapsulation processing, and store the control sequence obtained by the receiving sub-package 2 04 'so that the time-sharing media access controller ι42 or retransmission controller 144 points to the sequence direction . Furthermore, each digital modem 32 may include a master controller for controlling the entire operation of the modem. Although the '8B 10B line encoding is performed in the transmission packet in the above-mentioned preferred embodiment and used in the customer data, the encoding can be performed in all the packets. On the other hand, 8B10B encoding can be summarized as an mBnB encoding. Of course, the 8B10B code can include two 4B5B codes or a 6B7B code and a 2B3B code. The encoding method can be followed by encapsulation in other embodiments, even if there is encapsulation before encoding. In the description, for the sake of simplicity, the data decapsulated in the transmission buffer 120 by the decapsulator 46 is described. However, the decapsulator 146 actually decapsulates the data input or output by the transmission buffer 120 in the preferred embodiment of the present invention. In these examples, the 'unpacking stomach 148' unpacking the data output from the receiving buffer 130 is $ ridge λ s 1 and the data input to the receiving buffer 130. Alternatively, the deblocker 146 can be arranged between the forced report w volleyball volleyball between the encoder 152 and the equalizer 1 5 4 'to deblock the encoded data including the Lu Zhuzhu 彳 β pie and the deblocker 148. -r ----------------- Order --------- line (please read the notes on the back before filling this page) 522678 A7 _______B7 ___ V. Invention Explanation () is placed between the digital receiver 162 and the decoder 164. Although the filter used to selectively pass the data signal in the digital modem 32 or 82 is called a "band-pass filter", a high-pass chirper can also be used. Therefore, in this specification and the scope of patent application, the proper term “bandpass filter” should be understood to include “high-pass chirpers”. At the same time, although the communication between the switching hub 10 and the center module 20 and between the user module 74A and the data terminal 76A is performed according to the Ethernet protocol, other network protocols can also be used. On the other hand, the encoder 152 or the equalizer 154 may be omitted from the digital modems 32 and 82 in other preferred embodiments. When the encoder 152 is omitted, the decoder i64 should be omitted at the same time. After completing the description of the principles of the present invention of the preferred embodiments and other embodiments, it should be understood that the present invention can be modified in configuration without departing from these principles.
