Figure 73. Call routing example network

Note The SmartNodes in this Network may be owned and operated by the Com- pany or by a Service Provider.

The goal of this scenario is to connect the two PBX of sites A and B. The two sites are connected to a broad- band IP provider. The IP network is used to exchange data and voice calls between the two sites. On the IP network there is also a PSTN gateway (Node C) to an alternative voice carrier Melon that shall be used for most call destinations.

Sites A and B also have connections to the local ISDN network. This is called the local breakout connection. The local breakout is to be used as a fallback for ISDN data connections.

We assume the following:

•The number block for site A is 022 782 55 00 to 99

•The number block for site B is 033 665 2 000 to 999

•The Carrier Access Code (CAC) for Apple is 1055

•The Carrier Access Code (CAC) for Orange is 1066

•Carriers Apple, Orange and Melon do not support ISDN data calls (PC with ISDN Terminal Adapter behind PBX A)
