PVC Configuration Settings
Description
PVCs are configured using four menu items:
zPVC type—Defines the PVC type as Active, Connect on activity, or Passive.
zActive—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.
zConnect on activity—Specifies that the PVC connects when data is received.
This PVC remains dormant until it receives a data packet from the network.
zPassive—Specifies that PVCs make no attempt to connect.
zLCN low—Defines the minimum logical channel number for the PVCs you want to
configure.
zLCN high—Defines the maximum logical channel number for the PVCs you want to
configure.
zTimer interval—Defines the timer interval. The timer interval type depends on the
PVC type. The following timer intervals are available:
zCall timer interval—Defines the time interval (in seconds) at which an active
PVC will attempt to establish a connection to a destination.
zInactivity 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.
