7.5 Call Retry Strategy
If the DCM-200 is configured to originate calls or Internet connections, and a call fails
due to a data error or a network problem, the following retry strategy is followed:

the Primary Call Retry Rate.
2) Subsequent calls will be made at the Primary Call Retry Rate until the Primary
Call Retry Count is exhausted.
