In extreme conditions, for instance, if it is impossible to conduct a polling
session at the appointed time, the DPP uses a specific set of recovery
activities designed to serve the integrity of the primary AMA data in
compliance with the Bellcore recommendations in TR-TSY-000385. These
actions are discussed in the following paragraphs.

70% disk occupancy

Without disk capacity enhancement
When disk occupancy reaches 70% of maximum disk storage, the oldest
secondary (previously polled) AMA file is deleted so that this occupancy is
297-1001-537 Standard 01.02 December 1993
Note: The total disk capacity for the DPP is 95 percent of total disk space
available. When total disk capacity (AMA data=100 percent disk usage) is
referred to throughout this section in relation to AMA files, it refers to 95
percent of the actual DPP disk capacity.
