Description
The System provides three types of line appearances
• Direct Station Select (DSS) / Busy Lamp Field (BLF) Appearances
• Direct Line (DL) Appearances
• MCO Line Appearance
DSS/BLF Appearances
When a DSS/BLF key is programmed, it automatically provides one-touch dialing and DSS and BLF
for the assigned extension numbers. If desired, the DSS/BLF key can also provide ring or delayed ring
monitor. For example, you can set extension A as a DSS/BLF ringing key on extension B. When
extension A rings, the LED of the DSS/BLF key on extension B flashes and the phone rings.
Ringing or delayed ringing can be set on extensions which have a BLF key. The LED of the DSS/BLF
key flashes green
during ringing and the display shows the BLF extension number.
When extension A is in use, the LED of the DSS/BLF key on extension B lights red. If one extension
has the Call Forwarding or Do-Not-Disturb (DND) feature activated, the DSS/BLF key lights green.
