PVC Configuration Settings
Description
PVCs are configured using four menu items:
z PVC type—Defines the PVC type as Active, Connect on activity, or Passive.
z Active—Specifies that the PVC attempts to connect as soon as a link goes up.
If an immediate connection is not made, the PVC continues trying to connect
at a specified time interval. This time interval is established by the call timer
setting.
z Connect on activity—Specifies that the PVC connects when data is received.
This PVC remains dormant until it receives a data packet from the network.
z Passive—Specifies that PVCs make no attempt to connect.
z LCN low—Defines the minimum logical channel number for the PVCs you want to
configure.
z LCN high—Defines the maximum logical channel number for the PVCs you want to
configure.
z Timer interval—Defines the timer interval. The timer interval type depends on the
PVC type. The following timer intervals are available:
z Call timer interval—Defines the time interval (in seconds) at which an active
PVC will attempt to establish a connection to a destination.
z Inactivity timer interval—Defines the amount of time (in seconds) after a
connect on activity PVC is started before an inactive call is dropped or
disconnected.
