The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This sample configuration shows a Cisco 1417 Digital Subscriber Line (DSL) Router connecting to a Cisco 6130 Digital Subscriber Line Access Multiplexer (DSLAM) and terminating on a Cisco 6400 Universal Access Concentrator (UAC). The Cisco 1417 has been configured as a Dynamic Host Configuration Protocol (DHCP) server with PPP over ATM (PPPoA).
The Internet Service Provider (ISP) has given the subscriber a range of IP addresses, 10.0.0.1 to 10.0.0.X, with a mask of 255.0.0.0. IP address "10.0.0.1" will be manually configured on the Ethernet interface of the Cisco 1417. The remaining IP addresses will be assigned to a DHCP pool and leased to local LAN devices attached to the Ethernet network of the Cisco 1417.
