Time Settings for Interaction Between G150 and Communication
Manager
The group of time settings within the Timer window of the SO Gateway tab configure the timed
interaction between the G150 and the Communication Manager.
The timer settings are:
RAS Discovery Timeout (secs): Default = 5 secs; Range = 1-60 secs
The amount of time (in seconds) that the G150 will wait when looking for each active
gatekeeper (either at initial setup or when attempting to recover from survivable mode).
Host Loss Timeout (secs): Default = 20 secs; Range = 1-60 secs
The amount of time (in seconds) between the G150 receiving a first indication of
communication problems with Communication Manager and deciding that the connection to
the gatekeeper is down.
Host Lookup Time (secs): Default = 30 secs; Range = 1-60 secs
The amount of time (in seconds) allowed for the G150 to look for an active gatekeeper
before switching to survivable mode.
During this time, no call activity is allowed on the G150. Because of this lack of call activity,
the Host Lookup Time should not be set for an extended amount of time. On the other hand,
if it is set to a time shorter than the RAS Discovery Timeout, it is possible that the system
will switch to survivable mode before discovery has been attempted on all the entries in the
Gatekeeper List (both the Subtending Host List and the Alternate Gatekeeper List).
Terminal Retry Time (secs): Default = 120 secs; Range = 1-600 secs
This time setting only applies during sub-tending mode. The amount of time (in seconds)
between two consecutive registration attempts by a single entity (extension or trunk), which
was unable to register at the first attempt.
If the default settings for these timers are unacceptable, they can be configured by doing the
following:
1. Click
to receive a configuration form. The Receiving Config from dialog box appears
displaying the IP address of the G150. Enter the G150 system password.
2. Click System from the Configuration Tree and double click the G150 configuration on the
right hand side of the display window.
3. Click the SO Gateway tab. In the Timers area, make changes to the relevant timer fields.
4. Click OK.
5. If this is the last configuration being performed on Manager, click
Config To dialog box, accept the selected save option and click OK. Otherwise, continue
making additional configuration updates and perform a Save when ready.
