Description
In this example, the customer is using IP Centrex to serve all the stations. Every user has an IP Phone. An IP Centrex terminal adapter
is used to so that the fax machine be served as part of the IP Centrex group. Alternatively, the fax machine could have been served by
connecting it directly to the local Class 5 switch over a copper pair. In this case, the fax machine would still be part of the Centrex
group, but it would not be IP-enabled.
