Cisco router voip

Cox Communications [COX] will deploy Cisco Systems [CSCO] Internet routers and switches to satisfy demand for high-value IP services such as content delivery, and for virtual private networks (VPNs).

Cox chose several Cisco products including interconnecting metropolitan area networks (MANs) using the Cisco 12406 Internet Router in a backbone application, and the Cisco 7609 Internet Router and Cisco Catalyst 6509 and 6513 switches to support its regional and service data centers.

In addition, Cox has selected the ONS 15454 Metro Optical Transport Platform at many of these interconnection sites to enable maximum service density of voice and data services.

Cisco and Cox have had a long-standing business relationship, but there were some technological keys to this deal. Cisco says its 12406 Internet Router delivers five times the performance of the nearest competitor and is part of the Cisco 12000 Series Internet Routers that offer the industry's highest performance and scalability. Also, quality of service (QoS) capabilities played an important part in Cox's decision to choose Cisco. The demonstrated priority packet delivery capabilities of the 12000 series ensure that VoIP and other premium content packets are transported without loss and with the lowest latency and jitter.

Cox is deploying multiple Cisco 7609 Series Internet Routers at the distribution layer of each of its Regional Data Centers to support redundant metro aggregation for multiple cable systems in the network. Cox also is using the Cisco Catalyst 6509 and recently introduced Catalyst 6513 in each of its Service Data Centers, to provide connectivity for all network devices in their data centers network wide. >TK
