Appendix
The internal phone numbers of the terminal that are rung in the event of an external call
are defined in a call variant. Different call variants can be defined for the day or the night
service. Call variant 1 (day time service) and call variant 2 (night service) can be switched
over at any time from any telephone.
Call variant
Camp on tones during a telephone call signal that another subscriber is calling. The first
caller can be held in the line while you ask the second caller what he wants. This means no
calls are missed. Anyone who considers this as a disturbance can switch it off with the
camp on protection. The second caller either gets the busy tone or lands on an answering
machine for example.

Call forwarding - ISDN call forwarding
With this ISDN service feature, calls for your ISDN connection can be forwarded worldwide
to any other connection. You enter the destination number in your ISDN
telecommunications system and activate the call forwarding in your public exchange. The
exchange then re-routes all calls without the telecommunications system noticing (see call
diversion). With call forwarding on the system connection you always forward the whole
connection. On a multipoint connection you can divert every phone number (MSN)
individually to a respective different destination. Call forwarding is possible in the variations
permanent, when no answer and when busy. The call forwarding feature can only be used
by special agreement with your network provider.
Every connected telephone can be protected against unauthorised access by a 4-digit code
(telephone lock) so that with the exception of direct numbers, emergency numbers and
automatic dialling only internal numbers can be dialled. No code numbers are entered ex-
factory.

Dialling line (B-channel/S0 basic
access)
You can connect an external S0 basic access to your ISDN telecommunications system.
Every external S0 basic connection behaves like two conventional analogue dialling lines.
You therefore have two dialling lines (B-channels) on which you can make external calls
(local, long distance or international).
