Example Networks
The administration building configuration in Figure 4-7 shows the following connections:
• 155-Mbps UTP connections using LANE SVC connections to e-mail servers, for example, that
allow “bursty” traffic requiring signaling and less frequent use
• 155-Mbps UTP connections using PVC connections to DNS servers, for example, that allow short
duration connections without signalling
• T3 connection to WAN with access filtering to Hypertext Transfer Protocol (HTTP) and other users
• 155-Mbps UTP connection to edge router or default gateway with ATM Interface Processor (AIP)
installed and tag switching enabled
• T1 CES connection to PBX
• Video CBR using LANE SVC connections and T1 CES port adapters providing multicast
connections to selected users
• Soft PVC from source video connection to a destination at a remote site
• PVP tunnel to the remote sales building
• Frame Relay PVC to the telecommuter
