Configuring an ADSL WAN Interface Card on
Cisco 1700 Series Routers
This document describes asymmetric digital subscriber line (ADSL) one-port wide area network (WAN)
interface cards (WICs). These cards provide ADSL high-speed digital data transfer between a single
customer premises equipment (CPE) subscriber and a central office.
ADSL WICs are available in three variations: ADSL over POTS (WIC-1ADSL), ADSL over POTS with
Dying Gasp support (WIC-1ADSL-DG), and ADSL over ISDN with DyingGasp support
(WIC-1ADSL-I-DG). The ADSL over POTS WICs are commonly used to provide ADSL services over
ordinary telephone lines. The ADSL over ISDN WIC is used to provide ADSL services in those areas of
the world which have extensive ISDN backbones already in place.

  • Page 2: Feature Overview

    Analog phones DSLAM On Cisco 1700 series routers, an ADSL WIC fits into a Cisco 1700 series router chassis. The card supports data and voice networks through the asynchronous transfer mode (ATM) protocol with the AAL5 format. ATM quality of service (QoS) for permanent virtual circuits (PVCs) is also supported.

    POTS splitters and microfilters are used on telephone lines to ensure voice- and data-call quality. This section describes splitters and microfilters and tells how and when to use them with the Cisco 1700 series routers. POTS splitters result in the best data and voice performance when the router and the telephone are used on the same telephone line.
