1-Port, 4-Wire 56-kbps DSU/CSU Configuration Setup

This section describes using setup command facility to configure a 1-port, 4-wire 56-kbps DSU/CSU
WAN interface card. It discusses the following:

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.

Switched Mode

The following is an example of a 1-port, 4-wire 56-kbps DSU/CSU switched-mode configuration using
the setup command facility:
Do you want to configure Serial0/0 interface? [yes]:
Some encapsulations supported are
Choose encapsulation type
Switched 56k interface may either be in switched/Dedicated mode
Choose from either (switched/dedicated)
The following switched carrier types are to be set when in switched mode
(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]:
Note
The setup command facility will ask for only one telephone number for both IP and IPX (if enabled).
Please enter the phone number to call : 1234567890
