Example: Enterprise network with local breakout and IP carrier access
Consider the following Enterprise Network.
Site A
TA
LAN
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:
