situation. Please note however, that this is a service affecting procedure, and changes made
in this mode are both instantly implemented on the shelf, as well as written to the alternative
map for use when the feature is set to active in the case of an emergency.
There are two alarms associated with AMT. The first is AMT ACT which indicates that the
AMT MAP is active on the shelf. This alarm will remain active until a manual switch is
performed to switch back to the normal operating configuration.
The second alarm is SYNCAMT. This alarm indicates that the installed cards on the system
do not match the installed cards on the AMT MAP. When this occurs, NO AUTOMATIC
SWITCHING will be performed until the situation is remedied. For the use of this feature,
the stored configuration cannot and will not be used, and invalidates the ability to switch. This
alarm can be resolved by creating a new AMT MAP by one of the two methods described
above.
To access the AMT feature, the user needs to go to the sYstem level where the AMT feature
exists, as seen in figure Figure 5-92 on page 5-110. You can see from this Figure that the user
has to choose which provisioning method to use for AMT. The remote AMT (rem amT) is a
non-service affecting method to provision the circuits, but requires the use of a second shelf.
The other option is Act AMT (Act amt), which allows for on-shelf provisioning. This latter
method is a service affecting method to provision the emergency circuit setup.

We will address these two setup methods in the following two sections. The remote AMT
procedure does not require any impact to the shelf in question, so we will cover that method
first.

5.34.2.1 Remote AMT

AMT REMOTE is a non-service affecting way of provisioning an alternative
cross-connection mapping table using an offline or remote IMACS shelf, consisting of only a
CPU-7 processor and one of the supported Interface cards. Please note that the interface card
used in the remote shelf should be of the same type as the in the working shelf. This
configuration's sole purpose is to rEtrieve and load a working systems database, and allow the
operator a means to edit the working configuration without the consequences of a in-service
outage. The remote AMT main screen is seen below in Figure 5-93.
