Standby Mode
When two SG-CPM3s are present, one SG-CPM3 will be in Active or Manual mode, and the other SG-CPM3 will be in Standby. If the
active SG-CPM3 fails, the standby unit will automatically take over the control of the system. The IP of the SG-CPM3 is displayed on the
screen.

System Trouble and System Information
When a trouble is present on the SG-System III, the message “SYSTEM TROUBLE” will be displayed at the bottom of the screen.
• To view which trouble is present, press the UP and DN buttons simultaneously. All signals must be acknowledged before this is avail-
able.
• If no troubles are present, pressing the UP and DN buttons will enter open the System Information menu. In this menu items such as
Version information, Product ID, IP address can be viewed. If troubles occur once the user is in the Trouble menu, pressing the UP and
DN buttons again will allow the user to access the System Information menu.
• To return to the main screen, press the UP and DN buttons simultaneously, or wait for it to timeout before this is available.
AHS Table Management
New and modified AHS entries that are generated by incoming calls to line cards will be added to the backup CPM3. This operation will
happen every 5 minutes. At this time, all entries that are new/modified will be synchronized with the other CPM3. If the two CPM3’s are not
able to communicate to each other then the synchronization of the new entries will fail.
When the SG-Systems Console sets the AHS table to the CPM3 it will be written to flash once the set is complete.
The SG-System III will log "AHS Database Full" once the AHS table has reached capacity. The SG-System III will continue to log "AHS
Database Full" every day, at midnight, until space in the AHS table is made by deleting entries.
The AHS table size is 250,000 entries. This may be increased to 500,000 with the purchase of a license. Please contact your local sales rep-
resentative for more information on how to acquire additional licenses.
NOTE: The SG-CPM3ROHS is required in order to have the additional AHS entries.
