The intra-enterprise network deployment model for TelePresence systems connects not only buildings within a campus, but also geographically separated campus sites and branch offices. The intra-enterprise model expands on the intracampus model to include sites connected through a WAN(< 1 Gigabit), whether private WAN or VPN.
The intra-enterprise deployment model is suitable for businesses that often require employees to travel extensively for internal meetings. Deploying TelePresence systems within the enterprise not only improves productivity—by saving travel time—but also reduces travel expenses. Furthermore, the overall quality of work/life is often improved when employees have to travel less.
The network infrastructure of an intra-enterprise deployment model is a combination of Cisco Catalyst switches within the campus and Cisco routers over the WAN, which can include private WANs, MPLS VPNs, or Metro Ethernet networks. WAN speeds can range from 34 Mbps E3 circuits to 10 Gbps OC-192 circuits. Figure 1 illustrates the intra-enterprise TelePresence deployment model.

A valuable consideration when selecting WAN/VPN service providers is to identify those that have achieved Cisco Powered Network designation. Furthermore, an increasing number of Cisco Powered providers have earned QoS Certification for WAN/VPN services. This means that they have been assessed by a third party for the capability of their service level agreements (SLA) to support real-time voice and video traffic and for their use of Cisco best practices for QoS. For a list of recommended service providers, see the following URL: http://www.cisco.com/cpn.
The use of Cisco Powered networks is recommended—but not mandatory—for Cisco TelePresence intra-enterprise deployments. The key is meeting the service levels required by TelePresence

In both the intracampus and intra-enterprise deployment models, customers can also deploy multipoint TelePresence resources to facilitate multisite meetings (meetings with three or more TelePresence rooms). These resources might be located at any one of the campus locations or might be located within the service provider cloud as either a colocated resource or a managed/hosted resource.
