IP routed network
 
Internet or PPP Router
 
Some small businesses need high-speed connections 
 
into the Internet or need to connect to large global 
 
networks used by larger organizations. When 
 
communicating with another OfficeConnect Remote, 
 
the unit uses FastConnect, its own proprietary high 
 
speed protocol. However, in order to connect with 
 
other routers it needs to be configured to use the 
 
slower PPP protocol. PPP is used by many other routers.
 
Increasingly Internet service providers are offering 
 
access to the Internet over ISDN via an ISDN router. 
 
PPP routing over ISDN allows a simple cost-effective 
 
connection to the Internet or into a large 
 
organization’s global network.
