1-Port G.SHDSL WAN Interface Card for Cisco 2600 Series Routers
Feature Overview
2
Cisco IOS Release 12.2(4)XL
Feature Overview
G.SHDSL is ATM-based, multirate, high-speed (up to 2.3 MB), symmetrical digital subscriber line
technology for data transfer between a single customer premises equipment (CPE) subscriber and a
central office.
G.SHDSL is supported on the G.SHDSL WAN interface card (WIC-1SHDSL), a 1-port WAN interface
card (WIC) for Cisco 2600 series routers.
The G.SHDSL WIC is compatible with the Cisco 6015, Cisco 6130, Cisco 6160, and Cisco 6260 Digital
Subscriber Line Access Multiplexers (DSLAMs). The DSLAM must be equipped with G.SHDSL line cards
that are compatible with the DSL service to be configured.
The G.SHDSL WIC supports ATM Adaptation Layer 2 (AAL2), ATM Adaptation Layer 5 (AAL5), and
various classes of quality of service (QoS) for both voice and data service.
Benefits
• Enables business-class broadband service with voice integration, scalable performance, flexibility,
and security.
• Symmetrical WAN speeds (up to 2.3Mbps) over a single copper pair.
• Repeatable and has thirty percent longer reach than SDSL.
• Rate adaptive with G.HS “handshake” Protocol.
• Based on ITU Recommendation G.991.2 (Accepted Worldwide).
• Support for G.SHDSL Annex A (U.S. signaling) and Annex B (European signaling).
• Multiple G.SHDSL WAN Interface Cards configurable per Cisco 2600 series chassis.
• Toll-quality voice over delivery over AAL2, AAL5, and VoIP.
• Provides ATM traffic management and quality of service (QoS) features to enable service providers
to manage their core ATM network infrastructures.
• Critical IP QoS features.
• Supports ATM class of service features 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+).
• Operates back-to-back or through a DSLAM.
• Sustains up to 23 virtual circuits Per WAN on a WIC in Cisco 2600 series routers.
Restrictions
• The G.SHDSL WIC 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 G.SHDSL WIC does not support Dying Gasp in ANSI T1.413 Issue 2.
• The G.SHDSL WIC does not support available bit rate (ABR) class of service (CoS).
• The G.SHDSL WIC should be inserted only into onboard WIC slots or 1FE2W network modules.
This WIC is not supported in old combination network modules.
