Cisco Part Number: HWIC-2SHDSL=
The 2-pair (HWIC-2SHDSL) and 4-pair (HWIC-4SHDSL) symmetric high-bit-rate DSL high-speed WAN interface cards (HWICs) provide G.SHDSL connectivity to a Wide Area Network (Figures 1 and 2). The 4-pair symmetric G.SHDSL HWIC provides two ports of 4-wire or four ports of 2-wire connectivity options, whereas the 2-pair G.SHDSL HWIC provides two ports of 2-wire or one port of 4-wire connectivity options. The 4-pair symmetric G.SHDSL HWIC also allows bonding single or dual-pair G.SHDSL ports up to a single 8-wire interface with increased bandwidth by using Inverse Multiplexing over ATM (IMA) or data interleaving with M-pair mode. These cards are supported in all integrated services routers that have HWIC slots.
The 2-pair and 4-pair G.SHDSL HWICs supersede the existing G.SHDSL WAN Interface Card (part number WIC-1SHDSL-V3), which is a WIC-based G.SHDSL solution. The two new G.SHDSL HWICs provide higher performance and increased reach when compared to the G.SHDSL WIC. Table 1 compares the three interface cards.
G.SHDSL technology offers customers high-speed, symmetrical WAN connectivity at a lower monthly cost than traditional WAN circuits. The 2- and 4-pair G.SHDSL HWICs together with Cisco integrated services routers provide businesses the necessary bandwidth for critical traffic such as voice and video conferencing, and enable 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.
The first standardized multirate symmetric DSL, G.SHDSL has been an accepted worldwide technology standard based on ITU recommendation G.991.2. G.SHDSL is designed to transport rate-adaptive symmetrical data across a single copper pair at data rates up to 2.304 Mbps for a single pair or up to 4.608 Mbps over two pairs. Later enhancements (Annexes F and G) to the G.991.2 specification allow for increased performance up to 5.696 Mbps over a single copper pair. IMA technology allows the 4-pair G.SHDSL HWIC to offer data rates up to 2.304 Mbps per pair and up to 9.2 Mbps over four pairs. These rates cover applications traditionally served by HDSL, SDSL, T1, E1, and services beyond E1. Refer to Table 2 for the data rates supported by the 2- and 4-pair G.SHDSL HWICs (HWIC-2SHDSL and HWIC-4SHDSL) under different configurations.
Feature Summary
• Based on ITU Recommendation G.991.2
• Offers symmetrical WAN speeds up to 2.304 Mbps over a single copper pair and up to 4.608 Mbps over two copper pairs using ITU-T G.991.2 Annex A and Annex B
• Offers symmetrical WAN speeds from 768 kbps to 5.696 Mbps over a single copper pair and from 1.536 to 11.392 Mbps over two copper pairs using ITU-T G.991.2 Annex F and Annex G
• Offers symmetrical WAN speeds of 2.304 Mbps per pair up to 9.2 Mbps over four pairs on the 4-pair HWIC (part number HWIC-4SHDSL) by bonding with IMA Version 1.1
• Provides M-pair bonding on the 4-pair HWIC (HWIC-4SHDSL) using Annex F and Annex G with symmetrical WAN speeds of 768 kbps to 5.696 Mbps per pair for M = 2 and 768 kbps to 4.096 Mbps per pair for M = 3 and M = 4
• Supports Wetting Current (Section A.5.3.3 of G.991.2)

System Requirements
• The 2- and 4-pair G.SHDSL HWICs are supported on all modular Cisco Integrated Services Routers: the Cisco 1841, 2801, 2811, 2821, 2851, 3825, and 3845.
• The 2- and 4-pair G.SHDSL HWICs are supported in all Cisco IOS® Software feature sets.
• The routers listed previously need to run Cisco IOS Software Special Release 12.4(11)XJ to support the 2- and 4-pair G.SHDSL HWICs. They will also be supported on the Cisco IOS Software Release 12.4(6th)T and later.
• The system requires no additional flash or DRAM memory other than the specified minimum memory for the previously mentioned Cisco IOS Software releases.
• The 2- and 4-pair G.SHDSL HWICs can be inserted into any HWIC slot in the integrated services routers.
