PIN for secure session
A PIN temporarily varies the level of privacy for a secure session. The PIN may be up
to 4 digits, and is only valid for the current secure session. The same, or a different
PIN, may be used at the next secure session, and if required, must be entered each
time. Every party to the secure session must use the same PIN for successful secure
communication. The PIN may be entered at the time of going secure, or it may be
entered during a secure session to enable a more private conversation within the
Corporate or Global secure mode. Parties must know what PIN they intend to use
without mentioning it over the air.
