Routers and switches comprise the basic infrastructure elements of the Intelligent Information Network. When choosing a router, consider the number of phones, which call-processing solution you select, and the other functions the router will perform. When selecting a switch, Power over Ethernet (POE) removes the need for each phone to have an external power source.
Cisco Systems has a full range of switches that cater for 12 ports through to over 1000 with or without Power over Ethernet supporting a range of features such as embedded QoS, VLANs and port security.
