The Communication Manager network can contain multiple servers and equipment, including data-networking devices that servers control. Such equipment might be geographically dispersed across many sites. Each site might segregate equipment into distinct logical groupings of endpoints, including stations, trunks, and gateways, referred to as network regions. A single server system has one or more network regions. If one server is inadequate for controlling the equipment, multiple systems can be networked together. One or more network regions make a site, and one or more sites make a system, which in turn is a component of a network.
Types of networks:
Nondedicated network: Businesses have a corporate network, such as a LAN or a WAN. Over this corporate network, businesses distribute emails and data files, run applications, access the Internet, and exchange fax and modem calls.
This type of network and the traffic that it bears is a nondedicated network. The network is a heterogeneous mix of data types.
Converged network: A nondedicated network that carries digitized voice signals with other data types is a converged network. The converged network is a confluence of voice and nonvoice data.
Dedicated network: Network segments that carry telephony traffic are dedicated networks because the network segments carry only telephony-related information.
IP network: A digital network carries telephony and non telephony data in a packet-switched environment, such as TCP/IP, instead of a circuit-switched environment, such as TDM. The digital network is an IP network.
