Configure DSL Signaling Protocol

DSL signaling must be configured on the ATM interface for connection to your ISP. The

Cisco Secure Router 520 ADSL-over-POTS routers support ADSL signaling over POTS and the Cisco Secure Router 520 ADSL-over-ISDN routers support ADSL signaling over ISDN. To configure the DSL signaling protocol, see the “Configuring ADSL” section on page 4-6.

Configuring ADSL

The default configuration for ADSL signaling is shown in Table 4-1.

Table 4-1	Default ADSL Configuration
Attribute		Description	Default Value
Operating mode		Specifies the operating mode of the digital subscriber line	Auto
		(DSL) for an ATM interface.
		• ADSL over POTS—ANSI or ITU full rate, or
		automatic selection.
		• ADSL over ISDN—ITU full rate, ETSI, or
		automatic selection.
Loss of margin		Specifies the number of times a loss of margin may occur.	—
Training log		Toggles between enabling the training log and disabling the	Disabled
		training log.

If you wish to change any of these settings, use one of the following commands in global configuration mode:

•dsl operating-mode(from the ATM interface configuration mode)

•dsl lom integer

•dsl enable-training-log

See the Cisco IOS Wide-Area Networking Command Reference for details of these commands.
