set  [node node-id] x25 access reachable address address-name ...

    Modifies the an x25 access reachable address entity, which maps a
    destination network service access point (NSAP) address in an
    outgoing call to a DTE class/DTE address pair.  The modifiable
    attributes and their data types [in brackets] are:

    address extensions [boolean]
    destination [dte-address]
    dte class [simplename]
    mapping [Manual or X.121]

1  –  address_extensions

    Default: True          Value: True or false

    Specifies whether the "called address extension" and "calling
    address extension" fields are to be included in the outgoing call
    packet.

    Example:

    set x25 access reachable address x121 address extensions true

2  –  destination

    Default: No DTE        Value: DTE address
    address

    Manually entered DTE address. This address is used only if the
    mapping characteristic has the value manual.

3  –  dte_class

    Default: No class      Value: Class name
    name

    Name of the DTE class to be used in making the outgoing call. If
    not specified, any DTE class may be used.

    Example:

    set x25 access reachable address FRED dte class remote-class-0

4  –  mapping

    Default: X.121         Value: Manual or X.121

    Mechanism by which the destination DTE address is to be derived.

    manual  The destination DTE address is supplied manually by means
            of the destination characteristic.

    X.121   The destination DTE address is derived by an algorithm from
            an NSAP address in X.121 format. X.121 address mapping may
            only be specified with address prefixes of 36, 37, 49, 52
            and 53.

    Example:

    set x25 access reachable address x121 mapping X . 121
