5. ROUTINE MAINTENANCE
Overview
Note: Although procedure steps involving software commands can be performed via
the ASM (via an OA&M cut-through), someone must be present at the DRM office to
perform any hardware portions.
Routine maintenance consists of activities that are performed to maintain a high
degree of switch performance. Preventative maintenance is performed on a specified
schedule to ensure continuing peak overall performance of the network.
Since peak load periods, features, recent change activities, growth, etc., vary widely in
different offices, some tests, such as Routine Exercise (REX), may not have specific
test schedules that are best for all offices. In cases of this type, the Equipment Test
List (ETL) gives references where procedures, recommendations, and/or guidelines can
be found for the listed test(s).

Note: Tape backup of the entire office should be done at least once a month or more
often if many software updates are being added to the office. See Make Full Office
