System Configuration and Operation System Redundancy
11. Once all changes have been made to enable an emergency IMACS configuration, navigate
back to the sYs / rem amT level and select Backup from this screen. NOTE: This backup
must be used to backup an alternative map. Failure to use the backup command from the
rem amT screen will fail to put the proper AMT flag surrounding the information, and the
alternate map will not be correctly installed.
12. If removed, reconnect the IP connection and save the newly created alternative map to a
TFTP server.
INSATLLING THE AMT MAP ON THE WORKING SHELF:
1. Now that an alternative map is created and exists, you must pull it into your working shelf.
To accomplish this, go to the sYs / Act amt level.
2. From the AMT MGMT screen, choose rEstore to pull in the alternate map created in step
11 above. This will write the configuration to be used in the case of an emergency onto
the IMACS in the protected storage area of memory for use upon operator command or
one of the triggers set below initiates switching to the alternative map.
3. The user is now set to enable the trigger events, as seen in See “ALARM FILTER
TRIGGERS.” on page 115.
5.34.2.2 Active AMT
AMT ACTIVE is a service affecting method to provision an Alternative MAP, or AMT.
An AMT MAP is an alternate set of cross-connections that can be used when a facility fails in
order to maintain service for critical customers. The alternate mapping table is inactive and
secondary to the active base mapping table. Switching to the alternate map (AMT MAP) may
be activated manually by the user at any time, or performed automatically upon user
designated T1/E1 facility failure trigger settings in the ACT AMT menu screen. The Active
AMT provisioning screen is seen below in Figure 5-95.
