DSS/72 Console
Description
The DSS/72 console is a 72-key console that can be attached to a key telephone. The 72 keys on the
DSS/72 can be programmed as Direct Station Select (DSS) keys for internal lines.
In addition to providing direct station selection, the DSS keys also provide Busy Lamp Fields (BLFs)
that allow you to monitor the status of other extensions. The LED lights red when the assigned
extension is busy, and lights green when Call Forwarding or Do-Not-Disturb (DND) are activated.
For additional information, see “Flexible Function Keys” on page 158.
