Preliminary Draft Making calls 29
2. Depending on your phone’s configuration and the type of call,
press the Send/Talk key in one of the following ways:
If making a clear call: Your phone behaves like a commercial
phone, unless the person you are calling has a secure-only phone.
The screen displays CLEAR with the name and number of the party
you are calling. In that instance, you will be prompted to enter your
PIN unless you already logged on as a secure user.
If you are making a secure call: Usually, a screen appears asking
you to enter your PIN. After you enter your PIN, your phone
displays GOING SECURE and a series of messages. If this screen
does not appear, it means you already logged on as a secure user or
your security level does not require a PIN.
Once a secure connection is made the screen displays the
Department Agency Organization (DAO) description and the
following levels of security:
• TS: Top Secret
• SEC: Secret
• CONF: Confidential
• UNCLAS: Unclassified
• PROTEC: Commercially secure or “protected”
About making secure calls—secure “call setup”
Sometimes making a secure connection occurs quickly with just a
few status messages about the connection. At others times, the
connection takes a bit longer and requires you to respond to
several confirmation messages. The amount of connection time
depends on the amount of checking time your phone needs to
verify that the phone number you are calling is secure and to
determine its security level.
