MIS manager: “I want an integrated voice and data network.” Network manager: “We are designing a network based on the best practices available. We are using dedicated leased T1lines from each location to carry both voice and data to the network. Channels on each T1 are dedicated to either voice or data. From there, the voice is split off to our long-distance carrier. By the way, did I mention what a great rate we’re getting on long distance? And the data is routed to a frame relay network.”
