Occupation management
In ISDN your calls can be signalled, although you are already having a conversation
- in your own place by call waiting tone or at other free subscribers of the call distri-
bution. You already could be prevented from call waiting, but it was not possible so
far to prevent other free subscribers of the call distribution from signalling. With the
features “MSN busy” and “Switching off call waiting from central office” you are then
capable of distinguishing between internal and external call waiting and of preven-
ting further calls in case of engaged MSN (
multiple subscriber number).
MSN engaged
With MSN busy (Busy-on-Busy) your MSN is forced to be engaged, as soon as a
subscriber of the active call distribution is having a conversation with this MSN.
