Configure DSL Signaling Protocol

DSL signaling must be configured on the ATM interface for connection to your ISP. The Cisco 1801 supports ADSL signaling over POTS, the Cisco 1802 supports ADSL signaling over ISDN, and the Cisco 1803 supports SHDSL signaling.

Based on the router you are configuring, see one of the following sections to configure the appropriate DSL signaling protocol.

•Configuring ADSL
