When not in Message Status operation, the red LED next to each DSS button for
a room extension is used to monitor room availability, and the DSS button is used
to restrict the extensions when the rooms are not occupied.
The meaning of the red LED next to the DSS button for each room is shown in
Table 15.

The LED next to the DSS button for all other types of extensions is always
off and has no meaning.
Message Status Operation
Message Status operation activates when an operator presses the Message
Status button (the lower left feature button on the first DSS) while in normal
call-handling, calling group, CMS supervisory, or Extension Status operation. The
green LED next to the Message Status button is on when Message Status
operation is active.
While the position is in Message Status operation, the red LEDs next to the DSS
buttons for user extensions indicate whether or not the Message LED has been
turned on by a system operator and do not light when a Message LED has been
turned on by another source, such as a fax machine or another user. An LED
associated with a calling group extension or a pool dial-out code is always off
while the position is in Message Status operation.
If an operator wants to turn on the message-waiting LED to indicate that a
message is waiting, the operator first checks the LED next to the recipient's DSS
button to determine whether or not the recipient's message-waiting LED is on.
The operator's DSS or console LEDs do not light when a message-waiting LED
has been turned on by another source, such as a fax machine or another user. To
leave a message-waiting indication when the LED is apparently off, the operator
presses the programmed Send/Remove Message button, followed by the DSS
Meaning
The room is occupied, and the extension is in regular
call-handling state.
The room is vacant and available for occupancy, and outside
calls cannot be made from the extension.
The room is vacant and ready for cleaning. Outside calls
cannot be made from the extension.
