Information
Note: This command is applicable to BPI and BPI+ modem operation. The default value is acceptable for normal operation. The
shorter the life-time the more overhead will exist but gives some improvement in security.
CAUTION: The TEK lifetime must be more than twice as large as the largest TEK CM grace time to prevent denied CM registration.
To return the recommended setting (43000), use the no option.

<mac>
The MAC identifier. Valid numbers are 0-415.
