WAN Interface Card
The ADSL WAN interface card is a 1-port WAN interface card for the Cisco 1700 series of modular access routers. The card provides asymmetric digital subscriber line (ADSL) high-speed digital data transfer between a single customer premises equipment (CPE) subscriber and the central office. ??On Cisco 1700 series routers, the ADSL WAN interface card fits into a Cisco 1700 series router chassis. The card supports data and voice networks through the asynchronous transfer mode (ATM) protocol with the AAL5 format. ATM quality of service (QoS) for permanent virtual circuits (PVCs) is also supported.

Voice Interface Card
With voice/fax network modules, the Cisco multiservice access routers offer unparalleled multifunctional capabilities in a branch office solution, building on Cisco's strengths in LAN-to-LAN routing and dial access.??The voice/fax network modules for the Cisco multiservice access routers enable packet voice technologies including VoIP and VoFR. Cisco's voice solutions provide the means for integrating both voice and data within a single network and allow users to take advantage of services, such as toll-bypass, without sacrificing voice quality. This combination of voice solutions leverages Cisco's proven track record of being able to effectively handle time-sensitive traffic, such as Systems Network Architecture (SNA) over IP networks. Cisco IOS software also incorporates built-in quality-of-service (QoS) features along with standards-based (FRF.11 and FRF.12) encapsulation and fragmentation providing efficient transport of both voice and fax over IP and Frame Relay networks.

DSL Modem, External Enclosure, USB Interface, 24 Mbps
The D-Link ADSL2/2+ Ethernet/USB Modem (DSL-2320B) enables you to access a high-speed DSL Internet connection. The DSL-2320B supports the latest ADSL2/2+ standards to provide higher performance (up to 24Mbps1 downstream and 3.5Mbps1 upstream) and longer reach from your Internet Service Provider's (ISP) Digital Subscriber Line Access Multiplexer (DSLAM). The DSL-2320B is also backward compatible with standard ADSL. To create a home or office network, simply add a multi-port router2.

The network modules provide various port densities to meet customer requirements at various price points. The optional, integrated NT1 lets customers consolidate customer premises equipment (CPE) to provide multifunction dial access server, router, and other capabilities within the Cisco 3600/2600 series in power branch office environments.
