The Frame module provides framing functions for a communications
    link. It enables those who implement their own level 2 protocols
    to manage the links that use those protocols.

                                 NOTE

    You must install the WAN Device Drivers from the HP X.25 for
    OpenVMS product before you can refer to the frame module entities
    in an NCL command.

1  –  Subentities

    The entity hierarchy for the Frame module is:

    Node___Frame____Link
                  |
                  |_Port

    The FRAME entity is the top-level entity in the hierarchy
    belonging to the Frame module. The entity provides framing
    functions for a communications link. The entity does not provide
    any data link protocol capabilities, and is used by those who
    want or need to operate their own level 2 protocols.

    A FRAME LINK entity is associated with a physical line, and
    controls the framing protocol used on that line. There is one
    frame link entity for each physical line.

    A FRAME PORT entity represents an access point to the data
    link service offered by the Frame module. Ports are created and
    deleted automatically when a client of DDCMP uses the link.
