If you are using your relays as universal switching relays, you have the option of remote-
switching them from an internal or an external telephone. For information on setting this
functionality for your relays, refer to Chapter Universal switching relay on page I-60 in the
Installation and Configuration Manual. If you want to switch a remote-switching relay from
an internal telephone, it needs remote switching permission (see user program/as-delivered,
all extensions have remote switching permission).
You want to activate/deactivate a remote switching relay from your telephone:
Alternatively, from an external telephone:
This function makes it possible for service technicians or customer service staff to read or
program the configuration data of your PBX during an external connection.

For general information on programming by telephone and the tones that are issued
in this connection, refer to Page B-5
Settings “always on in daytime operation” and “always on in nighttime operation” (see
Chapter Universal switching relay on page I-60 in the Installation and Configuration Man-
ual) have higher priorities compared to the other switching options of the universal switch-
ing relay. This means that it is not possible, for example, to use the remote switching
function to switch off the relay while one of these two settings keeps it in the switched-on
status. With remote switching, you still hear an acknowledgement tone because the system
doesn't ignore this new desired switching status but just displaces it. If you chose the
“always on in daytime operation” setting and use the remote switching function to switch on
the relay during the day, it stays switched on at the transition to nighttime operation.

Remote switching from outside is conditional on your having informed the system
of the remote switching and programming MSN/DDI and that you know the external pass-
word (default setting is 4321) (see Chapter Necessary Settings for External Remote
Switching and Programming on page I-70 in the Installation and Configuration Manual).
