Message Status Operation-Led Meanings - AT&T MERLIN LEGEND System Reference Manual

Features
For calling group or CMS supevisor operation or for hotel Extension Status,
while the position is in message status operation, the red LED next to a DSS
button for a user extension indicates whether or not a user is on a call (off-hook),
has no call active (on-hook), or has the Do Not Disturb feature active. On a DSS
button for a calling group extension, the red LED indicates the status of the
queue. For a DSS button for a pool dial-out code, the red LED indicates trunk
availability.
The meanings of the red LEDs next to the DSS buttons while the system
operator position is in the message status operation are shown in Table 2-9.
