ZXDSL 831AⅡ User’s Manual 9 Figure 3.2-2 ZXDSL 831A Connection Schematic Diagram (Phone sets are Installed Before the Splitter)Ⅱ Note: In the circumstance where the first connection example is not applicable and you choose to use the second example, you must install a MicroFilter on the telephone cable (as illustrated in Figure 3.3-2, do not use a splitter to replace the MicroFilter). Installing a telephone directly before the splitter will lead to a failure of connection between the ZXDSL 831A and Ⅱthe device at central office side, or a failure of access into the Internet, or a slow connection speed. If you really need to add a telephone set before the splitter, you have to add a MicroFilter before the telephone set. Do not connect several telephones before the splitter. Moreover, do not connect several telephones with MicroFilters. The filter is not a standard-configuration device and you should separately purchase it from the operator. Connection procedures 1 Power off the equipment before all the other devices are connected. 2 Connect the network cables: Insert the RJ-45 Ethernet cable connector into the Ethernet interface of the ZXDSL 831A , and connect its other Ⅱ

Ⅱ z PHONE (or TEL): Connect the phone sets. The installation process is as follows: Connect the DSL interface of the ZXDSL 831A Ⅱto the MODEM interface of the splitter using the RJ-11 telephone cable, connect the phone set lines to the PHONE interface of the splitter, and then connect the user telephone cable port to the LINE interface of the splitter. 5 Connect the power Connect one terminal of the power adapter to the PWR interface of the ZXDSL 831A , and the other terminal to the socket on the wall, and then Ⅱswitch on the power of the ZXDSL 831A equipment. Ⅱ Checking all connection cables Check all connection cables following the below procedure. 1 Check the ADSL cable connection If the DSL LED is on upon power-on of the ZXDSL 831A , Ⅱit indicates that the ADSL line is correctly connected (Generally it takes one to two minutes to perform the ADSL connection). 2 Check the computer connection If both the LINK LED on the computer adapter and the Ethernet LED of the ZXDSL 831A turn green, Ⅱit indicates that the computer and the ZXDSL 831A equipment are correctly connected. Ⅱ 3 Check the telephone cable connection
ZXDSL 831AⅡ User’s Manual 11 The telephone cable is correctly connected if the received telephone signals are normal and free of noise. And the telephone will not be affected no matter whether the ZXDSL 831A is Ⅱpowered on or off.
13 Chapter 4 Install USB Driver If you want the ZXDSL 831A to be connected with a PC through Ⅱthe USB interface, you need to install the USB driver first. Read a certain section below pertinent to your operating system. If you have already installed the driver, skip this chapter. ZXDSL 831AⅡ is a device with both Ethernet Interface and USB Interface, which is independent, you may use either of them to connect to the different computers, in this way the two computers can connect to the network at one time. ZXDSL 831AⅡ can be seen as a simple two-port HUB. So, do not connect both the Ethernet Interface and USB Interface to a same computer. When using USB Interface, you must install the drivers. After installation, a virtual network card, "ZTE USB Remote NDIS Device", will be added into the computer. It has all the functions of a real network card, and it makes installation more easily NOTES: The following shows the steps for Windows®XP, the installation, configuration and uninstall of Windows®98 or Windows®2000 are similar to this. 4.1 USB Driver Installation Descriptions Install the driver following the system indication.

22 Appendix A FAQs 1 All indicators are off after the ZXDSL 831A equipment is powered onⅡ First make sure that you have inserted the power adapter of the ZXDSL 831A into Ⅱa working power socket and that the ZXDSL 831A has been powered on (the Ⅱswitch button is pressed down). If the indicators are still off after confirmation of the above items, the hardware is damaged probably. You may contact local operators for maintenance. Never dismantle the equipment by yourself. 2 Will ADSL affect the telephone conversation quality? Will making phone calls cause a slow online rate? ADSL separates voices from data through the frequency division multiplexing technology. Therefore, voices and data run in different paths without mutual interference. Neither the access rate nor conversation quality will fall even if you are in a call and on line simultaneously. 3 How to properly install telephone extensions or other devices on the ADSL line? It is recommended to first connect the ADSL splitter to the incoming customer end of the telephone cable, and then connect the phone sets to the splitter interfaces. Installing a telephone directly before the splitter will lead to a failure of connection between the ZXDSL 831A and Ⅱthe device at central office side, or a failure of access into the Internet, or a slow connection speed. Connecting some other electronic devices between the incoming customer end and splitter may affect the ADSL communications (since ADSL has a higher requirement for the line quality) and furthermore affect the normal operation of ADSL. If the phone sets are required to be connected before the splitter, you should serially connect the filter MicroFilter before the phone sets (Generally, to minimize interference, only one filter MicroFilter can be hang before the splitter). 4 Sometimes, the ADSL users cannot gain access to the Internet normally First check whether the ZXDSL 831A is in Ⅱthe normal state (Check the indicators with this user manual). If yes, the computer or application network may be faulty, which is unrelated with ADSL. If the ADSL MODEM is abnormal, check the status of indicators one by one to remove the fault. You are suggested to first make sure the following items before seeking help from operators: 1. The ADSL telephone cable connectors are proper; 2. The ADSL is away from the power cable and large-power electronic devices; 3. No telephone extensions and fax machines are installed between the ADSL incoming line and splitter; 4. The splitter has been correctly installed; 5. The ADSL MODEM is of good heat dissipation.
ZXDSL 831AⅡ User’s Manual 23 5 Password verification failure MODEM synchronization and connection are normal. However, sometimes the password fails to be verified. 1. Note that the account and password are case sensitive and some accounts contain a domain name. 2. Virtual dialup software. It is possible that sometimes the virtual dialup software is faulty, or conflict with other software in the operating system. At this time, you are suggested to reinstall the dialup software or replace it with other software. 3. Network adapter drive program problem. 4. In arrears of fees. Pay the fee timely in this case. 6 What are reasons for ADSL synchronization failure (also referred to link down or link establishment failure)? If the ADSL suddenly fails to be synchronized (link down) during application, usually the DSL indicator of the MODEM will not be solid on. You are suggested for checkup in the following sequence: 1. First check the quality of incoming cables and incoming cable connectors. 2. Install the ADSL Modem correctly based on the user guide, to minimize the number of taps. 3. Check whether the telephone cables and ADSL are in good contact or whether the telephone cables are normal. 4. Try to disconnect the splitter and directly connect the ADSL Modem to the incoming customer cable end to ensure that the problem is not due to improper installation or incoming customer line quality. If the ADSL can be synchronized again, it means that installation of the incoming customer part is improper. Please reinstall it according to the user guide. 5. If the ADSL still fails to be synchronized after the ADSL Modem has been connected to the incoming customer cable end, contact the operators to check whether it is due to external line failure or Modem failure. 6. If the splitter problem is determined, call the operators for maintenance or replacement. 7. The problem may be also due to the end office equipment fault of the operator. Call the operator to confirm it. 8. Too long connection cable between the splitter and ADSL Modem may cause poor anti-interference performance and synchronization difficulty. Therefore, the connection cable should not be too long.
ZXDSL 831AⅡ User’s Manual 24 7 The authenticated user names and passwords cannot be re-authenticated? This problem may be due to the following reasons: 1. Your account has expired or you are a defaulting subscriber (please pay the deficit sum). 2. You move into a new area. Because the account and the path PVC are bundled by some operators, your previous account and password cannot be authenticated after you changed your path. 3. One of your accounts has logged on successfully. Therefore, you will fail to be re-authenticated because the operator has recognized the uniqueness of this account 4. Maybe you failed to deregister your account timely in the Broadband Access Server (BAS) when you were off line abnormally, so the BAS or the billing system deemed that your account was still available. Therefore, your re-login may fail because of uniqueness of your account You are suggested to redial up later. If still failing, contact the operator for a solution.
