Central Answering Position

Direct Station Select (DSS) keys and Busy Lamp Field arrays. Each of
these keys is programmed with the Terminal Number (TN) of the telephone
to which it corresponds. To program these keys use LD 11, explained
later in this chapter.

You can use these keys to visually find out the status of a telephone, or
to contact and extend calls to telephones. The status of a telephone is
indicated by the key lamp in the following ways:

Idle — The key lamp is off.
Busy — The key lamp is steadily lit.
Forwarding — The key lamp is flashing.
