2.3.6 Communications used in a WAN

When using a WAN with JP1/AJS3, make sure you use them in a communications environment with secure communications and stable communication lines.

You can ensure secure communications in a communications environment by, for example, using a VPN.

If a communication line is unstable, job delays or errors whose causes are hard to identify might occur. To prevent such problems, use a communication line that has a stable data transfer rate.

When using a WAN for manager-agent communication, use JP1/AJS3 products of version 10-00 or later. Do not use a WAN for connections with products of version 09-50 or earlier.

The following table shows whether a WAN can be used with particular combinations of product versions.

A WAN can be used for connections between the following programs and components whose version is 09-50 or earlier:

We do not recommend using a network for which you are charged based on the amount of time or amount of data.

If you do use a WAN environment for which you are charged based on the amount of time or amount of data, you can reduce communication costs by, for example, disabling KeepAlive (which requires a continuous connection that checks connectivity with the destination) in the environment settings. Setting devices such as routers to disconnect automatically when inactivity is detected will also reduce costs. However, monitoring from JP1/AJS3 Console View requires an online environment. Monitoring cannot be performed if the line is automatically disconnected when inactivity is detected.

When you perform monitoring from JP1/AJS3 Console View in a WAN environment for which you are charged based on the amount of time or amount of data, note the following:

  1. The line will remain connected.

  2. Communication will be performed randomly when the status of the monitored object changes.

To reduce communications costs, therefore you must log out and terminate JP1/AJS3 Console View when not in use. Communication does not occur when no one is logged in.
