Chapter 3 Configuring with the Command-Line Interface Configuring 1-Port G.SHDSL WAN Interface Card • Supports AAL2 and AAL5 services and applications (including voice), 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 UBR+]), and up to 23 virtual circuits on a WIC in Cisco 2600 series and Cisco 3600 series routers. • Provides ATM traffic management and quality of service (QoS) features to enable service providers to manage their core ATM network infrastructures. This feature is supported on the following router platforms: • Cisco 2610 • Cisco 2611 • Cisco 2612 • Cisco 2613 • Cisco 2620 • Cisco 2621 • Cisco 2650 • Cisco 2651 • Cisco 3620 • Cisco 3640 • Cisco 3661 • Cisco 3662 Restrictions • The ADSL WAN does not support dual latency. When the DSL link is intended to support both voice and data traffic simultaneously, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic. • The ADSL WAN does not support Dying Gasp in ANSI T1.413 Issue 2. • The ADSL WAN does not support available bit rate (ABR) class of service (CoS). • The ADSL WAN should be insertedonly into onboard WIC slots or 1FE2W, 2W, 1FE1R, 2FE2W network modules. This WIC is not supported in old combination network modules. Prerequisites A G.SHDSL WIC must be installed in the router to match the DSL service to be configured. A compatible G.SHDSL line card must be installed in the DSLAM. Configuration Tasks See the following sections for configuration tasks for this feature. Each task in the list is identified as either required or optional: • Configuring G.SHDSL on a Cisco Router, page 3-60 (required) OL-1957-04 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers 3-59
