ATM Connections Supported by Cisco 12000/10720 Router Manager
ATM connections are modeled in Cisco 12000/10720 Router Manager as objects that are deployed beneath an ATM interface. Cisco 12000/10720 Router Manager supports two types of ATM Connection: Terminating Permanent Virtual Circuits (PVCs), and Switched Virtual Circuits (SVCs).
Note The ATM connections can be viewed only in the Component Managed view.
Both types of ATM connection are now discussed in greater detail.
PVC Connections
A PVC is a permanent logical connection that must be configured from source to destination. PVCs save bandwidth associated with establishing a circuit when a virtual circuit must exist all the time. You can deploy a PVC (which creates the PVC within Cisco EMF), apply an ATM Traffic Descriptor to the PVC, then create the connection on the device. Deploying and creating a PVC creates a
Terminating PVC Connections
A terminating PVC connection object is modeled in Cisco 12000/10720 Router Manager as a single object deployed beneath a ATM interface (see Figure
