DSL Bundle Features and Benefits
DSL helps companies reap the benefits of dramatically lowered WAN costs, improved global connectivity, and high reliability, while providing sufficient
bandwidth to combine such critical traffic as voice and video with data. Additionally, service providers can increase their subscriber revenues by
bundling services and by offering differentiated service levels through Service Level Agreements (SLAs).
Cisco 2600XM Routers
The Cisco 2600XM modular multiservice access routers are ideal for DSL connectivity. They deliver a rich, integrated package of routing, firewall, dial,
Packet Voice Gateway and VPN functions. The Cisco 2600 series together with the ADSL or SHDSL WAN Interface Modules (WICs) are the perfect
solution for a variety of businesses requiring high-speed business-class DSL connectivity on a secure, high-performance modular platform.
ADSL WIC (WAN Interface Card)
The WIC-1ADSL included with the 2600XM-ADSL Router Bundles is based on the ITU G.992.1 (G.dmt) and ITU G.992.2 (G.lite) standards. The
ADSL WIC operates at speeds of up to 8Mbps downstream and 1.5Mbps upstream. Multiple ADSL WICs can be provisioned per 2600XM to provide
even higher bandwidth or WAN backup. The WIC-1ADSL with the 2600XM supports a variety of ATM QoS mechanisms. These included Class of
Service (CoS) features Constant Bit Rate (CBR), Variable Bit Rate (VBR) in real time and non real time, and Unspecified Bit Rate (UBR). In addition
support for a variety of IP QoS mechanisms is also be available.
SHDSL WIC (WAN Interface Card)
The WIC-1SHDSL-V2 included with the 2600XM-SHDSL Router Bundles is based on the ITU G.991.2 standard. The SHDSL WIC operates at
symmetric speeds of up to 2.3Mbps over a single copper pair and 4.6Mbps over two copper pairs. Multiple SHDSL WICs per 2600XM can be
provisioned for extra bandwidth or WAN backup. Additionally, the SHDSL WICs can operate back-to-back for campus environments. The
WIC-1SHDSL-V2 with the 2600XM supports an identical set of ATM and IP QoS mechanisms as are available with the WIC-1ADSL with the 2600XM.
