Message Indicator Lamp
The Message Indicator lamp (located at the top, right-hand corner of the phone)
shows the same indications as the key. The Message Indicator lamp flashes
whenever there is a waiting message.
NOTE: Because the telephone system allows for customization, your phone’s mes-
sage indicator may have been reprogrammed to indicate a different feature.
DSS/BLF and Mini-DSS
Generally, the Model 8450 Direct Station Selection/Busy Lamp Field (DSS/BLF) unit
is used by individuals that handle a high volume of incoming calls, such as reception-
ists. The DSS/BLF provides one-key access to up to 50 extension numbers or a pro-
grammable feature. For more information about programming and using the DSS,
refer to the current Axxess Administrator’s Guide (part no. 550.8001).
The Model 8416 Mini-DSS unit is a scaled-down version of the full-sized DSS/BLF
unit. This optional unit adds 16 user-programmable keys to your phone. These keys
can be programmed as any of the following:
• DSS keys: Provide one-key access to extension numbers and display the status of
the extension associated with the key (see page 57).
• Feature keys: Provide quick access to frequently-used features (see page 56).
• Secondary extensions: Allow one-key access to calls ringing or holding at
another station (see page 58).
The DSS/BLF and Mini-DSS lamps indicate the status of the extension or feature
assigned to the key. These indications are shown in the table below.
