ecommunications system is programmed for your

numbers in the barred range. You hear the error

Answering calls
You can distinguish internal from external calls by
different ringing rhythms on your telephone provi-
ding your terminal supports different ringing
rhythms.

telephone rings and you Lift handset.
Knocking - You receive a call while you are
speaking. The call knocks. You hear the internal
knocking tone once (internal call) or the external
knocking tones several times (external call). You
can answer the call and switch back and forth
between the two calls (brokerage).

reject it, the caller hears the busy tone if only your
telephone is being called. If several telephones
are being called (see call allocation) only the party
with a call waiting will be disconnected.
