Each DSS button can correspond with extension numbers for one of the
following:
User extension number.
Line/trunk number (801-880)
Pool dial-out code (Hybrid/PBX) only
Calling group extension number
Paging group extension number
System operator Park zone access code
Access code (usually a 9) for Automatic Route Selection (ARS-Hybrid/PBX
only) or Idle Line Preference (Key and Behind Switch only)
Remote Access dial code

The use and the meaning of the LEDs for each DSS button depend on the
extension represented by the button and whether the system operator position is
used for normal call handling with or without active message status operation,
such as a calling group or CMS supervisor position with or without active
message status operation or, if Extension Status is assigned to the position,
Extension Status in the hotel configuration.
