SONET Networking DEPLOYMENT OF SONET IN THE ACCESS NETWORK As shown in Figures 5-6 and 5-7, SONET can be deployed in the access network, particularly where new fiber is being installed and/or existing routes are being exhausted, to provide new networking capabilities and transport of new services. Different application scenarios are described below: Simple Point-to-Point A point-to-point application is relatively simple to implement. Instead of a pairgain link such as twisted pair copper, fiber is used to connect a control terminal from a switching node switch to a remote terminal. SONET will transport multiple DS-1s to the CSA with plenty of room for growth. The overhead channel links all systems together for integrated OAM&P. 54 Add/Drop Application The SONET system transports traffic from the switching node to a terminal at a CSA or customer premises location. To pick up or drop off additional traffic, intermediate SONET add/drop multiplexers are used for CSAs located along the way. ADMs could also be connected in a closed OC-n loop to provide a survivable ring topology.
