Using the Setup Command Facility
Choosing Circuit-Switched or Dedicated-Line Service
The switched-56 WAN interface card is configured for dedicated or leased-line service by default, but it
can also be configured for circuit-switched service. Depending on the type of data transmissions you
typically use, you can configure the switched-56 WAN interface card for circuit-switched or
dedicated-line service.
Generally, circuit-switched service is ideal for short duration data transmissions or as an alternative route
if a dedicated line fails. For example, circuit-switched service is ideal for sending electronic mail
messages or doing such tasks as updating inventory and ordering records from one network database to
another at the end of each day.
Dedicated service is ideal for heavy network traffic. Dedicated service is ideal if you need a constant
network connection or you need connection for more than eight hours per day.

(at&t, sprint or other)
Choose carrier (at&t/sprint/other)
Do you want to map the remote machine's ip address in dialer map? [yes]:
Do you want to map the remote machine's ipx address in dialer map? [yes]:
