Manager
ATM conn ections ar e mode led in Cisco 12000/1072 0 Router Ma nager 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 Th e ATM connecti ons can be viewed o nly in the Co mponent Manage d view.
Both types of AT M connec tion are now discusse d in greate r 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
deplo y a PVC (wh ich creates the PVC with in Cisco EMF), a pply an ATM Traff ic De scriptor to the PVC,
then create the connection on the device. Deploying and creating a PVC creates a cross-connection
within on e devic e.
