Protection Against Wrong Connections
Preventing Transfer to a Wrong Connection
This feature prevents the automatic switching equipment in the telephone network
from accidentally connecting you to the wrong terminal.
However, it does not help you if you dialed the wrong number yourself. So, even if
this feature is switched on, you should still check your operation panel display to
check whether you have reached the correct terminal, and be ready to press the
Stop key if the wrong terminal’s RTI or CSI is displayed.
Your machine compares the number that you dialed with the CSI received from
the other end. If the CSI is not the same as the telephone number, the
transmission is stopped.
This feature has to be switched on by a service technician.
NOTE: If you cannot send a message to a certain location while using this fea-
ture, contact the other end and make sure that they have stored their CSI
correctly. (If the other party is using a machine made by another maker,
they may not be familiar with the term CSI. Explain that you are interested
in the telephone number that they stored in the machine for identification
purposes)
