T 4.40 Unsuitable fitting out of the RAS client
operational environment
Often RAS connections cannot be established due to incompatibility of the
technical equipment. But even where the technology is compatible the
connection can fail if dial-in points for the relevant service provider are
lacking or cannot be accessed. The threats which can occur in this area include
the following:
- The power parameters between RAS client and remote location are
incompatible (220V/110V).
- The modem connections between RAS client and remote location are
incompatible.
- The switched network that is normally used (telecommunication service
provider, Internet service provider) is not available at the remote location.
- The remote phone number is transmitted incorrectly or in an incompatible
manner to the RAS server (where authentication is effected using Calling
Line Identification Protocol, CLIP).
Moreover, it is virtually impossible to consider all the possible technical
problems which can occur in any operational environments when planning the
RAS system.
