multiservice access routers and integrated services routers offer a wide variety of WAN connectivity modules to

accommodate the range of application needs in customer networks. The new Cisco 1-Port G.SHDSL WAN Interface Card (part

number WIC-1SHDSL-V3) offers G.SHDSL-based WAN connectivity for modular routers deployed in small to medium-sized

branch offices (Figure 1).

OVERVIEW

The new G.SHDSL WAN interface card (WIC) provides 1-port symmetric high-bit-rate DSL (SHDSL) connectivity to a WAN. The modular routers

that support the new card are the Cisco 1841, 2801, 2811, 2821, 2851, 3825, and 3845 series integrated services routers; the Cisco 1721, 1751,

1760, 2600XM, 3725, and 3745 series multiservice access routers; and the Cisco 2691 Multiservice Platform. The interface card is available on

Cisco access routers, starting with Cisco IOS

Software Release 12.4(3) Mainline and special Cisco IOS Software Release 12.4(2)XA. The first T-

train image that will support the new interface card will be 12.4(3rd)T.

The new interface card is the latest G.SHDSL-based WIC for Cisco modular routers. It supersedes existing interfaces (part numbers WIC-1SHDSL

and WIC-1SHDSL-V2) while maintaining feature parity with WIC-1SHDSL-V2. (Table 4 later in this document compares the three interface cards.)

G.SHDSL technology offers customers high-speed, symmetrical WAN connectivity at a lower monthly cost than most traditional WAN circuits.

Using single or dual-pair copper wires, Cisco access routers with SHDSL interface card (part number WIC-1SHDSL-V3), can provide businesses the

necessary bandwidth for critical traffic such as voice and videoconferencing, and can allow customers to save money by integrating voice and data

traffic on the same WAN link. Service providers can increase subscriber revenue by bundling services and offering differentiated service levels

through service-level agreements (SLAs).

A product of the ITU-T, SHDSL is the first standardized multirate symmetric DSL technology. It is designed to transport rate-adaptive symmetrical

data across a single copper pair at data rates from 192 kbps to 2.3 Mbps, or 384 kbps to 4.6 Mbps over two pairs. This covers applications

traditionally served by high-bit-rate DSL (HDSL), symmetric DSL (SDSL), T1, E1, and services beyond E1. G.SHDSL represents the worldwide-

accepted DSL standard for symmetrical DSL, based on ITU recommendation G.991.2.
