Embodiment

Further specify the utility model below by embodiment.

Hardware is realized: the hardware of ADSL+WLAN integrated access equipment of the present utility model is based on the CX82310 chip of conexant company and realizes that its hardware principle block diagram as shown in Figure 4.CX82310 is the acp chip of this integrated access equipment among Fig. 4, functional circuits such as this chip internal is integrated RAM 940 processor modules, DSP module, high-speed AD/DA modular converter, Switching Module are mainly finished functions such as AFE (analog front end) signal processing, high-speed AD/DA conversion, ADSL signal are resolved, procotol processing, modulation control, handshaking.The ancillary equipment of chip CX82310 comprises telephone line interface 5, separator 4, transmission/reception mixed bridge-circuit (AFE) 3, and control circuit (PHY) 10, Ethernet interface 11, in addition, also comprise FLASH memory 6, static immediate access device (SDRAM) 7, reset circuit 8, crystal oscillating circuit 9, power supply 12 etc., its hardware is formed with common similar.6 functional modules that the utility model increases are comprehensively in wireless receiving module 2.

The course of work of this integrated access equipment is as follows:

The ADSL aggregation of data inserts: for reception condition, from the process of the signal on telephone wire telephone line interface 5, enter this device, through separator 4 with voice signal and ADSL Signal Separation, voice signal is given telephone set, the ADSL signal is sent into the transmission/reception mixed bridge-circuit (AFE) 3 of integrated access equipment, AFE with the glitch-free merging of ADSL signal with separate, reception amplifier and high-speed A/D converter that the received signal of separating is sent into CX82310 are transformed into digital signal, CX82310 resolves the ADSL signal by configuration requirement then, handle, and data are sent to Ethernet interface control circuit (PHY) 10 or WLAN by data demand; For the transmission situation, CX82310 will change the ADSL signal into through D/A from the data of PHY or WLAN acquisition, through transmit amplifier the ADSL signal will be sent to AFE again, and AFE is sent on the telephone wire after signal is merged.

The WLAN aggregation of data inserts: during the start of this integrated access equipment, determine the congested conditions of wireless channel by the channel detecting, and select an idle channel job.WLAN user could connect with this integrated access equipment after the Service Area Identifier symbol (SSID) and the number of channel are set.In the wireless receiving situation, wireless receiving module 2 sends data to CX82310 by pcmcia bus 23 after receiving the signal demodulation, and CX82310 finishes the exchange of data, and converts ADSL signal synthesis access INTERNET to; In the wireless transmission situation, from INTERNET send data after CX82310 handles, be sent to wireless receiving module 2 by pcmcia bus 23 and send to the user.

Software is realized

The software of this integrated access equipment is based on the VxWords embedded OS and realizes that all functions all are to form by function module design.Its workflow such as Fig. 5.

Behind this integrated access equipment electrifying startup, system at first carries out self check, and systems soft ware can be realized two operations simultaneously after self check was finished, and detects whether the WEB configuring request is arranged on the one hand, enters ADSL on the other hand and is connected with WLAN.When entering the WEB configuring request, require the user to key in username and password earlier, after username and password is correct, to enter next step, be provided with if domestic consumer then enters domestic consumer, can be user's configurating PVC, configuration packages agreement, user guiding is provided with and will informs user WAN, LAN, the setting of contents such as NAT is as PPPOE, VCI, the situation that is provided with of CPI; If advanced level user, except that carrying out common the setting, can also detect route, fire compartment wall, various senior settings such as configuration fail safe aspect rule, use the local area network (LAN) of this device to carry out physical address (MAC) as the user and filter, concerning the network equipment, MAC Address be unique, can not change.The high-level network administrative staff are by the MAC Address of tool detection to the network equipment, and this address inserted MAC Address hurdle in the mac address filter item, as choose the blacklist item, will filter the IP bag that the network equipment of MAC Address correspondence sends when this equipment provides service on net so, do not influence the miscellaneous equipment online, if choose from the name individual event, this equipment can allow the IP bag of MAC Address correspondence to pass through so, and other network equipment will be forbidden online.To the crowded Auto-Sensing of wireless channel, local dns server supports, preserves by submitting to after settings such as blacklist white list user management are finished, and this equipment can be saved in the FLASH memory parameter is set, and restarts.If do not have WEB to be provided with then this equipment carries out the crowded Auto-Sensing of wireless channel earlier, determine the WLAN working channel, carry out ADSL then and connect, PPPOE dialing and user's service on net.When network disconnected, this package can reconnect automatically.
