Break-In (Direct Dialling In For Virtual Pisn Subscribers) - ASCOM Ascotel 2025 System Manual

4.7.3 Break-In (Direct Dialling in for Virtual PISN
Subscribers)
An incoming connection from the outside is routed into the PISN at the PINX clos-
est to the calling party. For this the calling party must know the correct dial-in
number for the PISN. This number can be displayed to him as a CLIP number, for
example when calling from the PISN. Typical break-in applications:
• A company with several different locations wishes to present itself to the out-
side through one location only.
• Traffic from a virtually networked system to other systems in the leased-line
network is always to be routed via the nearest system in the private network.
