Changing software variables involves contacting the proper MIB.
To change software variables:
1. Contact the AT-VP504E FXS with a MIB browser.
You can use the built-in MIB browser of the Unit Manager.
For more details, see the
IP Communication Server
Administration
manual.
2. Open the proper MIB.
3. Select the specific variable you want to modify.
All variables in the MIBs have a description as well as a list of
possible values. Read the comments very carefully before
changing a variable’s value. The variables are subdivided in
categories to facilitate your work.
4. Modify the variable according to the proper values listed.
5. Redo steps 3 and 4 for each variable you want to modify.
Some variables will require to reboot the AT-VP504E FXS.
The reboot will delete all statistics stored and will overwrite all
volatile variable values in the MIBs.
