In the existing network access device, the xDSL access technology is mostly used to implement the network connection. xDSL is a generic term for various types of DSL (Digital Subscriber Line), including ADSL, RADSL, VDSL, SDSL, IDSL, HDSL, and so on. Fast access technology is a newly developed network access technology in recent years, and can realize 1Gbps throughput network signal transmission in copper cables as long as 100 meters, so that network operators can fully utilize the existing infrastructure, and can directly realize network access at optical fiber speed in areas with copper wires without rewiring.

It should be noted that the client terminal device provided in this embodiment provides a uniform network connection interface to the outside, and a user can access to different types of networks through the network connection interface. The client terminal equipment also comprises a line switching device, at least two signal transmission processing lines, a line control device and an equipment bus. Wherein each signal transmission processing line is used for processing a specific type of transmission signal. The line control device is used for detecting the signal type of an input signal in the network connection interface, controlling the line switching device to perform line switching according to the signal type of the input signal, connecting the network connection interface to a signal transmission processing line corresponding to the signal type of the input signal, and controlling the signal transmission processing line to perform corresponding transmission and processing on the input signal. The device bus is connected to each device in the client terminal device, and is used for transmitting signals between the devices in the device.
Specifically, the line control device monitors a transmission signal in a network connection interface in real time, detects a signal type of the input signal when the network connection interface is detected to receive the input signal from the network, obtains a corresponding transmission signal type, and controls a line switching device to perform line switching according to the transmission signal type, so that a first port in the line switching device is connected to a second port corresponding to a signal transmission processing line corresponding to the transmission signal type, and the input signal can be transmitted to the signal transmission processing line corresponding to the signal type of the input signal. Then, the line control device controls the signal transmission processing line to correspondingly transmit and process the input signal, and transmits the processed input signal to the device bus, so that the device bus sends the input signal to the routing protocol layer or transmits the input signal to a corresponding device in the device for subsequent processing.
It should be further noted that, in some more preferred embodiments, the network connection interface may be an RJ11 interface, and the line control device may be a Central Processing Unit (CPU). The client terminal equipment may further include two or more transformers respectively connected between the line switching device and each signal transmission processing line. In some more preferred embodiments, the client terminal device may further include a line protection device, connected between the network connection interface and the line switching device, for protecting the line. Fig. 6 is a schematic diagram of a client terminal device including a line protection apparatus.
According to the embodiment of the invention, the line control device and the line switching device are added in the client terminal equipment, so that the automatic detection of the signal type of the equipment transmission signal and the automatic switching between different signal transmission processing lines according to the signal type of the transmission signal are realized, the client terminal equipment can process different types of transmission signals under the condition of providing a uniform network connection interface externally, the process of identifying and judging the type of the network signal before the user accesses the network can be omitted, the operation difficulty of the user accessing the network is reduced, and the user experience is improved.
More preferably, the at least two signal transmission processing lines include an xDSL signal transmission processing line and a g.fast signal transmission processing line; the transmission signal type is xDSL or G.fast.
It should be noted that, in some more preferred embodiments, the number of the signal transmission processing lines in the client terminal equipment is at least 2, that is, the signal transmission processing lines at least include an xDSL signal transmission processing line for processing an xDSL type transmission signal and a g.fast signal transmission processing line for processing a g.fast type transmission signal. Therefore, the client terminal device can at least process the transmission signals of the xDSL type and the transmission signals of the G.fast type under the condition of providing a uniform network connection interface for the outside.
In some specific embodiments, the network connection interface in the client terminal device is preferentially connected to the g.fast signal transmission processing line, and the line control device only controls the line switching device to perform line switching when detecting that the signal type of the input signal received by the network connection interface is xDSL or other, so as to connect the network connection interface to the xDSL signal transmission processing line or other signal transmission processing lines.
In another preferred embodiment, on the basis of the above embodiment, the network connection interface is connected with at least one authentication server;
the detecting the type of the transmission signal to obtain the type of the transmission signal specifically includes:
generating a signal type verification request according to the transmission signal;
sending the signal type authentication request to at least one of the authentication servers;
and when receiving a verification passing message returned by any one of the verification servers, determining the transmission signal type as the signal type corresponding to the verification server returning the verification passing message.
It should be noted that the client terminal device detects the signal type of the input signal in the network connection interface by communicating with the authentication server. Specifically, after detecting an input signal in a network connection interface, a client terminal device generates a corresponding signal type verification request according to the input signal, and sends the signal type verification request to verification servers connected with a local area, so that the verification servers verify the signal type of the input signal according to the signal type verification request. Wherein each authentication server corresponds to a signal type. After receiving the signal type verification request, the verification servers analyze the signal type verification request so as to judge whether the signal type of the input signal is the same as the signal type corresponding to the verification server, if so, a corresponding verification passing message is generated and returned to the client terminal equipment, and if not, the signal type verification request is discarded without other processing. When the client terminal equipment receives the verification passing message returned by any one of the verification servers, the signal type of the input signal is confirmed as the signal type corresponding to the verification server returning the verification passing message.
In some specific embodiments, the verification sequence of the signal types may also be set. For example, when the client terminal device can simultaneously transmit and process an xDSL type transmission signal and a g.fast type transmission signal, it may be set to first verify whether the transmission signal is of the g.fast type, and when the transmission signal is not of the g.fast type, to verify whether the transmission signal is of the xDSL type. Specifically, the client terminal device firstly sends a signal type verification request to a verification server corresponding to a g.fast type, if any one of the verification servers returns a verification passing message, the signal type of the transmission signal is determined to be g.fast, if no verification passing message is returned by any of the verification servers after N (N ≧ 1) times of signal type verification request sending, the signal type of the transmission signal is determined not to be g.fast, and the information type verification request is sent to the verification server corresponding to the xDSL type for verification of the transmission signal type, or the type of the transmission signal is directly determined to be xDSL.
In a further preferred embodiment, on the basis of the above embodiment, each of the signal transmission processing lines includes a specific hybrid circuit, a reception filter, a gain amplifier, an analog-to-digital converter, a modem, and a forward error correction device;

The core transmission processing circuit comprises a receiving filter, a gain amplifier (programmable gain amplifier) and an analog-to-digital converter, and the bus connection device comprises a modem and a forward error correction device.

Fig. 7 is a schematic diagram of a signal transmission processing circuit and the connection relationship between the signal transmission processing circuit and the inside and the outside.
After the line control device detects and obtains the signal type of the transmission signal in the network connection interface and controls the line switching device to perform line switching according to the transmission signal type, the transmission signal is transmitted to a specific hybrid circuit in a signal transmission processing line corresponding to the transmission signal type for analysis. Then, the line control device controls the core transmission processing device in the signal transmission processing line to obtain the transmission signal from the specific hybrid circuit, and sequentially performs filtering, gain amplification, analog-to-digital conversion and the like on the transmission signal, and sends the processed transmission signal to the bus connection device. Then, the line control device controls the modem in the bus connection device to perform echo suppression, time domain equalization (to reduce intersymbol interference between subcarriers), and radio frequency interference suppression on the transmission signal, and sends the transmission signal subjected to the processing to the forward error correction device. Finally, the line control device controls the forward error correction device to perform forward error correction on the transmission signal, and after separating out the mixed error correction bits (HEC) therein, the transmission signal is sent into the device bus, so that the device bus sends the transmission signal to the routing protocol layer or transmits the transmission signal to a corresponding device in the device for subsequent processing.

Specifically, after detecting an input signal in the device bus, the client terminal device generates a corresponding signal type verification request according to the input signal, and sends the signal type verification request to verification servers connected to the local, so that the verification servers verify the signal type of the input signal according to the signal type verification request. Wherein each authentication server corresponds to a signal type. After receiving the signal type verification request, the verification servers analyze the signal type verification request so as to judge whether the signal type of the input signal is the same as the signal type corresponding to the verification server, if so, a corresponding verification passing message is generated and returned to the client terminal equipment, and if not, the signal type verification request is discarded without other processing. When the client terminal equipment receives the verification passing message returned by any one of the verification servers, the signal type of the input signal is confirmed as the signal type corresponding to the verification server returning the verification passing message.
In some specific embodiments, the verification sequence of the signal types may also be set. For example, when the client terminal device can simultaneously transmit and process an xDSL-type transmission signal and a g.fast-type transmission signal, it may be set to first verify whether the transmission signal is of the g.fast type, and when the transmission signal is not of the g.fast type, then verify whether the transmission signal is of the xDSL type. Specifically, the client terminal device firstly sends a signal type verification request to a verification server corresponding to a g.fast type, if any one of the verification servers returns a verification passing message, the signal type of the transmission signal is determined to be g.fast, if no verification passing message is returned by any of the verification servers after N (N ≧ 1) times of signal type verification request sending, the signal type of the transmission signal is determined not to be g.fast, and the information type verification request is sent to the verification server corresponding to the xDSL type for verification of the transmission signal type, or the type of the transmission signal is directly determined to be xDSL.

Then, the line control device controls the modem to perform multicarrier modulation on the transmission signal, and sends the multicarrier-modulated transmission signal to the core transmission processing line. Then, the line control device controls the core transmission processing line to perform digital-to-analog conversion, gain amplification, filtering and other processing on the transmission signal in sequence, and the transmission signal after the processing is sent to a specific hybrid circuit for integration through a network driver. Finally, the specific hybrid circuit transmits the transmission signal to a network connection interface, so that the network connection interface uploads the transmission signal to a network.
