Aiphone AN-8000 manual

screenshots it is still “New System” which means an upload has not been attempted and the default system name and password should still work, assuming of course no one else has attempted to upload settings to that device. You can directly log in and undo settings you don’t like specifically or reset it to default settings using the Delete All Settings option in the System Maintenance menu.

Once you get in, you’ll have the option of viewing the settings in Japanese or English, and then the navigation menu gives you several useful tools.

Resetting to Factory Default Settings

To reset to factory default settings go to System Maintenance and click Delete All Settings if you need to erase the System Settings you’ve uploaded to it, it will also reset the IP address to the initial 192.168.1.1, so you may need to change your router’s settings (most of the time you won’t) and your computer’s IP address to match that subnet. This will also delete all configuration settings that associate it with a particular system, so if you accidentally isolated equipment intended for a single system on two separate systems (for instance one is on a system named Example and the other is on AN-8000 they can’t talk to each other), Delete All Settings will erase that association (and the IP address will be reset) so they can be placed on their intended system.

If the browser does not ask you for a user name and password, either the IP address is not correct, or the unit may have a connection or power problem. If you get an error that you don’t have the correct User Name or Password, exhaust every combination you can before sending the equipment to the factory for a repair restore.

Testing using Network Connection

Another way of testing the system is to use the Network Status menu and test a particular device’s ability to communicate with every other AN IP enabled device on the system, such as an AN-8000EX, AN-IP doors or masters, or the AN-8000MI. If there are port forwarding problems, firewalls blocking ports or IP addresses this test will fail in some way and will help determine which segments of your network are not communicating with other segments, or if a particular device is having a connection or power related issue. This option is especially useful for testing across a Wide Area Network.

If a single device fails a communication test the first thing to do is to point your browser to that address and see if you can get in. Does it have the configuration

uploaded? Does it ask for a user name and password? Remember to try the system name and password you gave it in addition to the default AN-8000 and guest password. If it only accepts the default information it probably doesn’t have the right configuration, download the correct configuration from a working device and upload the file to the one that doesn’t. If the configuration is there but you are still having intermittent issues, try a new port on the switch or perhaps investigate power issues.

Troubleshooting Communication Problems Sometimes over a network there will be voice

drop outs after a connection has been made. There may be a delay between networks or a difference in timing for routers that can make communication lag. Sampling Frequency Correction (section 8-3 of the manual) covers a scenario where an exchange or an MI is located on a different network segment or across a WAN in which there may be slight discrepancies in time for each router between the networks. To correct for this, the Sampling Frequency Correction tab for one exchange or MI in each network must be designated as either the transmitter or receiver for this purpose. This is not required for the AN-8500MS nor the AN-8540DS and there is no Sampling Frequency Correction tab for those IP stations.

You may also run into voice operated exchange (VOX) problems in areas with loud ambient noise that can interrupt the conversation and change the direction unintentionally. This could force a master in a loud area to be stuck transmitting this sound and never allowing the speaker to play the sound picked up by the door station’s microphone as the guest responds. Use the handset or force the conversation into Push to Talk (PTT) to see if this is a network bandwidth issue or a VOX issue.

If the network used has a lot of traffic there could be bandwidth related voice drop outs. The default High Quality Sound Transmission Mode setting for the Network Settings tab of each device uses 130kbps. Bandwidth Saving Transmission Mode will introduce a delay of 1/3 of second to the conversation and drops the bandwidth requirement to 50kbps to get around the problem of high traffic networks pushing the voice path to a lower priority (as defined in Quality of Service sections in some router configurations) when high priority traffic comes through. If the end users complain about voice drop outs during specific consistent times of the day, bandwidth narrowing may help.
