MultiVoice Gateway for the MAX— User’s Guide Preliminary November 23, 1998 1-9
Figure 1-5 shows an example of an ISP network offering connectivity between New York, Los
Angeles, and San Francisco.
Figure 1-5. Example of an ISP offering data and voice services
At each Point of Presence (PoP) in the figure, the ISP configures one MAX unit dedicated to
supporting voice traffic and another MAX unit dedicated to supporting data services. Each
MultiVoice Gateway and MAX Remote Access server is connected to a backbone IP router,
which connects all PoPs over an IP network. System administrators use the Gatekeeper in San
Francisco, to manage the MultiVoice network.
The ISP supplies MultiVoice customers with the phone number of a local MultiVoice Gateway.
Data customers, using modems or ISDN devices, dial the phone number of a local MAX
Remote Access server. All customers send traffic over the same IP network.
Local 800 service
For example, local 800 or 888 service can be much more cost-effective than traditional 800 or
888 service. Typically, leasing charges are less, and MultiVoice technology can eliminate
long-distance phone charges. Suppose a company maintains a customer service department,
offering their customers a traditional 800 or 888 phone number that they dial to receive
assistance.
