Configuring 1-Port G.SHDSL WAN Interface Card Chapter 3 Configuring with the Command-Line Interface Step 2 Step 3 rotary number transport input telnet Set the router to use previously-defined rotary group. Configure the router to accept inbound Telnet connections. This configuration procedure ensures that a user trying to dial out using Telnet is connected to the first free line in the rotary group. Configuration Example Refer to theAppendix A, "Cisco 3640 Central Site Configuration to Support ISDN and Modem Calls" for an example of the configuration. Configuring 1-Port G.SHDSL WAN Interface Card This section describes how to configure the Multirate Symmetrical High-Speed Digital Subscriber Line (G.SHDSL) feature supported on the 1-port G.SHDSL WAN interface card (WIC) (WIC-1SHDSL) on Cisco 2600 series and Cisco 3600 series routers in Cisco IOS Release 12.2(4)T. This section includes the following sections: • Restrictions, page 3-59 • Prerequisites, page 3-59 • Configuration Tasks, page 3-59 • Configuration Examples, page 3-64 G.SHDSL is ATM-based, multirate, high-speed (up to 2.3 MB), symmetrical digital subscriber line digital 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, a 1-port WAN interface card (WIC) for Cisco 2600 series and Cisco 3600 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. Listed below are some benefits of this feature: • Enables business-class broadband service with voice integration, scalable performance, flexibility, and security. • Aggregates G.SHDSL and other transport options into a single box. • Provides G.SHDSL high-speed digital data transmissions between customer premises equipment (CPE) and the central office (CO), or between routers located within a customer site. • Supports ITU G.991.2 (SHDSL). • Supports ANSI T1.601 (BRI), ANSI T1.410 (DDS), and ANSI T1.403 (T1 carrier). 3-58 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers OL-1957-04
