multiple devices. For remote ofﬁces or teleworkers, the Cisco Easy VPN Remote feature can be conﬁgured with the

Cisco Router Web Set Up tool (CRWS), a Web-based GUI. This makes VPN conﬁguration as easy as entering a

password, increasing productivity and decreasing support costs.

Intranet Toll-Quality Voice

The Cisco 827-4V router, with four voice ports, is an H.323 standards-based voice-over-IP (VoIP) gateway today.

The Cisco 827-4V router supports standards-based H.323 with Registration, Admission, and Status (RAS) protocol

support, providing gateway-to-gatekeeper functionality. The gatekeeper maps destination phone numbers to IP

addresses. (See Figure 2.)

The key advantages of the Cisco 827-4V router intranet toll-quality voice capability include the following:

Support for New World Services

The Cisco 827-4V router enables service providers to offer small business and enterprise telecommuters additional

voice services by using their existing copper infrastructures. By taking advantage of DSL high-speed access, service

providers can provide integrated, multi-line voice services over a single pair of copper wires. This enables service

providers to offer new voice and data services without incurring the cost of a truck roll or expensive product forklift

upgrade.

Award-Winning Toll-Quality Voice Technology

The Cisco 827-4V router employs the award-winning toll-quality voice technology used in the Cisco AS5300 VoIP

Access Server Gateway.

This award-winning technology is an integral part of Cisco IOS Software and is available on a range of different

products, from the service provider trunking gateways to customer premises equipment (CPE) such as the Cisco

827-4V router—all with the same, best-of-breed voice quality.

The Cisco 827-4V router enables multilayer prioritization of trafﬁc, supporting ATM, Point-to-Point Protocol (PPP),

and IP functionality. This product supports optimized voice compression at the application level with powerful

digitalsignalprocessors(DSPs)anda full range of codecs toofferhigh-qualityderivedvoice lines, thereby minimizing

the use of bandwidth.

Standards-Based Voice Technology

The voice functionality of the Cisco 827-4V rouer , which is based on H.323 standards, enables third parties to

develop applications to a standard protocol, resulting in an ecosystem of compatible voice applications such as

enhanced call control via gatekeepers, service billing, and network management. Such an ecosystem provides a

complete solution for rapid deployment of intranet voice services for small business and enterprise teleworkers.
