5.7.2.3.5 Remote Control
General
To allow remote control for the system (see CHAPTER 8, page 117), you must
activate the function
Enable Remote Control .
FIG. 49 REMOTE CONTROL
By assigning a password, the caller needs to authorise himself first before he
can control the system remotely. The password check can be done in two dif-
ferent ways:
• If the option
Enable ISDN Password Check
is activated, the password
check is done in the D channel (signalling channel) of the ISDN connection.
If the passwords do not match, the caller is rejected immediately without
establishing a connection

.
If the password check is successful, the call is accepted automatically, even
if the automatic answer of calls is
not enabled (see Page 54,
Enable Auto
Answer
).
• If this function is not supported by the ISDN connection, the password
check is not done before the connection has been established.
A call to the system which is to be controlled remotely
must be accepted
manually , if the automatic answer of calls is not activated (see Page 54, En-
able Auto Answer ).
ATTENTION Without any further security measures, anybody who knows the calling
number of the system and has the fee-based
Option: Remote Control Soft-
ware can control the system remotely.
Therefore, please activate the security system described below at any rate.

In this case, the caller does not have to pay any connection charges.
NOTE The password check in the D channel is only available if the feature sub
addressing is enabled for the ISDN connection.
