The value of tmnxMobServRfOcCf1Limit specifies the limit
(in megabytes) for an amount of memory on the first compact flash that
can be used for the Accounting Requests (ACR) storage. Once the
threshold has been reached, the system can no longer support accurate
charging.
If the compact flash is not available then tmnxMobServRfOcCf1Limit
will be set to 0.
If tmnxMobServRfOcCf1State is enabled and the value of
tmnxMobServRfOcCf1Limit is 0, then maximum available memory on the
second compact flash can be used for the ACR storage.
