4.If a DISA security code is required (see the System Administrator), dial the code and listen for CO dial tone.
...or if a DISA security code is not required, you hear CO dial tone.
The dial tone is present for 10 seconds to allow direct dialing of a station internal number or CO line access code. If a number is not dialed, the system automatically causes the DISA CO line to ring at telephones as a normal incoming call. Then, if the call is not answered within 15 seconds after the ringing starts, it disconnects.
If the correct code is not entered, the call is disconnected.
A timer tone plays (approximately four mins.) that both parties hear after the call was made.
