318CHAPTER 20: DCC CONFIGURATION COMMANDS

When receiving an incoming ISDN call, the device with the dialer call-incommand configured first verifies that the caller is valid before processing the call. If the remote PBX does not provide the calling number, the call is dropped directly.

n On a dial interface (physical or Dialer) configured with the dialer call-incommand, you need to configure the corresponding dialer route command or dialer number command, making sure that the dial-number configured in the command is the same as the remote-number configured in the dialer call-incommand.

Related command: dialer callback-center.

Example # Configure the device to place return calls for ISDN calling number 8810152.

<Sysname> system-view [Sysname] interface bri 1/0

[Sysname-Bri1/0] dialer route ip 100.1.1.2 8810152

[Sysname-Bri1/0] dialer call-in 8810152 callback

dialer circular-group

Syntax dialer circular-group number

undo dialer circular-group

View Dial interface (physical) view

Parameter number: Number of dialer circular group, same as the one defined in the interface dialer command. It ranges from 0 to 1023.

Description Use the dialer circular-groupcommand to assign the physical interface to a dialer circular group in C-DCC approach.

Use the undo dialer circular-groupcommand to remove the interface from the dialer circular group.

By default, a dialer circular group does not include any physical interfaces.

In C-DCC, you can assign a physical interface to a dialer interface by assigning it to the dialer circular group associated with the dialer interface. While a physical interface can belong to only one dialer interface, a dialer interface includes all physical interfaces assigned to its associated dialer circular group. When placing a call on the dialer interface, DCC selects the physical interface with higher priority.

Related command: interface dialer.

Example # Add interface Serial 2/0 and Serial 2/1 to dialer circular group 1.

<Sysname> system-view

[Sysname] interface dialer 1

[Sysname-Dialer1] quit

[Sysname] interface serial 2/0
