Menus Reference Manual: Edit Remote Site - Activation Set-up Menu
4 - Inactivity Timer
The Inactivity Timer option defines the Connection Management Idle Timer that is used to determine when an
ISDN call will be suspended or terminated. This timer monitors traffic on the link. If the link traffic is idle, this router
is set to use Connection Management, and there are LAN sessions using the link, the ISDN call will be suspended.
When the Inactivity Timer is set to off, this router will not suspend or terminate the ISDN call. This may be used to
allow only one of the routers to monitor the link traffic to determine when to suspend or terminate the ISDN call.
The Inactivity Timer is also used for IP Address Connect configurations. If connection management is not used, the
inactivity timer will monitor link traffic. If the traffic on the link is idle for a time longer than the inactivity timer, the
link will be terminated and then be made available for the next IP address connect request.
Default: [60 sec]
Range: off, 20 to 3600 seconds
5 - Recovery Timer
The recovery timer sets the delay before the secondary link is activated or deactivated when the primary link goes down or
is reestablished. This acts as a stability timer to give the primary link a period to recover before the backup is activated and
to ensure that when the primary link is reestablished that it stays up for a significant time before the backup link is
dropped.
Default: [15 sec] (note: if Frame Relay is enabled, this default changes to 60 sec.)
Range: 15 to 300 seconds
Note: This option will only be displayed if the Connection option in the Edit Remote Site menu is set to "recovery"
or "recovery_with_threshold".
