Multi-Exchange (CO) Line Appearance

When a DSS/BLF key is programmed, it automatically provides one-touch dialling 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.

Four DSS/BLF modes are available as follows:
