Chapter 47. Configuring and Monitoring Dial Circuits
This chapter describes how to configure dial circuits on a dial circuit interface
mapped to a V.25bis,V.34,or ISDN interface. It contains the following sections:
v“Dial Circuit Configuration Commands”
v“Dial Circuit Monitoring Commands” on page650
Dial-in and Dial-out interfaces are special types of dial circuit interfaces.
Notes:
1. PPP dial circuit interfaces can use an ISDN, V.25bis,or V.34 network as the
base-network interface.
2. FR dial circuit interfaces can use an ISDN or a V.25bisnetwork as the base
network interface.
3. Switched SDLC Call-In dial circuit interfaces use a V.25bisnetwork as the
base-network interface.
4. X.25 circuits can be used over ISDN D-channels for BRI.
5. Dial-Out circuit interfaces use a V.34network as the base-network interface.
6. Dial-In circuit interfaces can use an ISDN or V.34network as the base-network
interface.
For information on how to configure dial circuits for use with:
vISDN interfaces, see “Chapter 45. Using the ISDN Interface”on page 611.
vV.25bisinterfaces, see “Chapter 41. Using the V.25bis Network Interface” on
page 579 .
vV.34interfaces, see “Chapter 43. Using the V.34 Network Interface” on page 595.

Dial Circuit Configuration Commands

Table83 describes the dial circuit configuration commands. Enter the dial circuit
configuration commands at the Circuit Config> prompt. Youmust restart the router
for configuration changes to take effect.
Toaccess the Circuit Config> prompt, enter the network command followed by
the interface number of the “dial circuit”. (The dial circuit number was assigned
when you entered the add device dial-circuit command.) Youcan enter the list
devices command at the Config> prompt to display a list of the dial circuits that you
added.

Command Function
? (Help) Displays all the commands available for this command level or lists
the options for specific commands (if available). See “Getting Help”
on page 10.
Delete Deletes the inbound call settings from the dial circuit configuration.
Encapsulator Allows you to change the data-link protocol configuration.
List Displays the dial circuit configuration parameters.
