Cisco 827-4V - Router - voice card - EN, ATM - refurbished
The Cisco 827-4V enables service providers to offer small offices 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, multiline 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. The Cisco 827-4V employs the award-winning toll-quality voice technology used in the Cisco AS5300 VoIP access server gateway. In June 1999, the Cisco AS5300/voice gateway won BCR Magazine's "Best in Test, " with unprecedented scores to date for any VoIP products tested by Mier Communications. This test is the leading method of testing voice quality in telephony applications. 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 premise equipment such as the Cisco 827-4V - all with the same, best-of-breed voice quality. The Cisco 827-4V 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 digital signal processors (DSPs) and a full range of codecs to offer high-quality derived voice lines, thereby minimizing the use of bandwidth. The voice functionality of the Cisco 827-4V, 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 offices and enterprise teleworkers.
