1-Port ADSL WAN Interface Card

This feature module describes the 1-port Asymmetric Digital Subscriber Line Wide Area Network (ADSL WAN) Interface Card feature for Cisco 1700 series routers. It describes the benefits of the new feature, supported platforms, configuration, related documents, and provides command reference information.

This document includes the following sections:

Feature Overview

The Cisco 1700 series routers, which include the Cisco 1720 and 1750 models, are modular access routers for small and medium businesses and small branch offices. Cisco 1700 routers deliver routing, firewall, and Virtual Private Network (VPN) functions for Internet data and voice applications.

The ADSL WAN interface card is a 1-port WAN interface card (WIC) for the Cisco 1700 series of modular access routers. The card provides asymmetric digital subscriber line (ADSL) high-speed digital data transfer between a single customer premises equipment (CPE) subscriber and the central office.

The ADSL WIC is compatible with the Alcatel Digital Subscriber Loop Access Multiplexer (DSLAM), the Cisco 6260 DSLAM with Flexi-line cards and the Cisco 6130 DSLAM with Flexi-line cards. It supports Asynchronous Transfer Mode (ATM) Adaptation Layer (AAL)5 (AAL5) and various classes of Quality of Service (QoS) for both voice and data service.

Note ADSL is a last-mile access technology, which has an asymmetrical data rate running over a single copper wire pair.

Benefits

Enables business class broadband service with voice integration, scalable performance, flexibility, and security.
Aggregates both ADSL and other transport options into a single box.
Provides both POTS and ADSL high-speed digital data transmissions between the customer premise equipment (CPE) and the central office (CO).
Supports ITU G.992.1 (or G.DMT, which specifies full-rate ADSL).
Supports and complies with ANSI T1.413 issue 2, and ITU G.992.1 (G.DMT for full-rate ADSL).
Supports ATM AAL5 services and applications, ATM class of service (constant bit rate [CBR], variable bit rate-nonreal time [VBR-NRT], variable bit rate-real time [VBR-rt], and unspecified bit rate [UBR]) and up to 24 virtual circuits on a WIC in Cisco 1700 routers.
Provides ATM traffic management and Quality of Service (QoS) features to enable service providers to manage their core ATM network infrastructures.

Restrictions

The ADSL WAN interface card does not support dual latency. When the ADSL link is intended to support both voice and data traffic simultaneously, the link should be configured for either all fast-path data or all interleave data with an interleave depth of zero to insure that latency is minimized. In addition, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic.

Supported Platforms

Cisco 1720
Cisco 1750
