Call Filtering

In x25tool, the parameters for Call Filtering can be accessed through the Services menu.

The parameter values are stored in the configuration files: /etc/opt/SUNWconn/x25/x25secuconf and /etc/opt/SUNWconn/x25/x25secupid.

Use X.25 Call Filtering to define which incoming calls will be authorized.

Service Name

Select PAD, TCP-IP, CLNP, OSI, Other, or None to indicate from which service you want to accept incoming calls.

Call User Data

Select Matches, Starts with, or Don't Care to indicate which callers to accept calls from. If you select Matches, or Starts with, you will also need to type in the data.

Accept Calls

Specify a time period when calls will be accepted. You can set this up so it is repeated Weekly, Daily, or One Time only.

Link Number

You can restrict which networks you will accept calls from by specifying the Link Number you will accept calls from. If the link number is set to 255, then X.25 will accept calls over any link.

Calling Address

This is the address of the machine that initiated the call. Set this to Starts with, Matches, Ends with, or Don't Care.
