CWOn - Call Waiting On
Switches call waiting for the extension on/off.
This function does not require any data entered when programmed. This function cannot be programmed through the phone by the user.
The 
CWOn key toggles call waiting on/off. When call waiting is on, CWOn is shown with a 
symbol. When call waiting is on and the extension is on a call, any additional call receives ringing rather than busy tone.

DCW - Dial CW
Allows the user to force another extension to have call waiting mode on for the duration of a call attempt. This function is not supported in the USA.
This function requires the target extension number to be entered when programmed. That number is then shown next to DCW. This function cannot be programmed through the phone by the user.
Normally, if the target extension is on a call and doesn't have call waiting on, any new call will receive busy tone or be diverted to voicemail. Pressing 
DCW will cause the target extension to receive call waiting indication and allow the caller to hear ringing until answered.
