Access Failure Messages
When calls to the RPSD Lock are disconnected without reaching the PBX modem, the Lock
generates an access failure message that is sent to standard output and saved in the system
activity log. The access failure message is also sent as a reply to the caller whose attempt failed
(the message can only be received, however, if the caller has an RPSD Key with an
administration terminal or printer attached to it). A dedicated printer connected to the Aux. Port
on the Lock enables you to maintain a permanent record of access failure messages.
Note: These messages are not necessarily a sign of a malfunction or other problem. If the
RPSD Lock fails to detect a Key, for example, on the caller’s line, this is likely because
there is no Key on the caller’s line and the Lock is fulfilling its role properly by
preventing unauthorized access. The actions suggest in Table 5-1 are only to be
taken in the event that a known Key user who is supposed to have access to the RMATS
channel is unable to gain access.
You can also obtain an access failure message for the most recent call attempt by using the
Last Call Status Test. See Last Call Status Test in this chapter for a detailed explanation of
the use and limitations of the Last Call Status Test.
There are nine codes that explain access failures. Table 5-1 explains the type of access failures
and the appropriate action to take.
