Considerations and Constraints
One or two DSSs can be connected to an MLX-20L or MLX-28D telephone.
DSSs cannot be connected to an MLX-10™, MLX-10D™, analog multiline, or
single-line telephone.
Only a DLC or QCC can have a DSS.
Operator Park Zone codes must be included in the extension number range
specified for one of the Page buttons.
If an extension is busy because features are being assigned through system or
centralized telephone programming, the red LED next to the associated DSS
button is on to indicate the busy condition.
For a QCC only, pressing the DSS button for a trunk number, Listed Directory
Number, or unassigned extension number while active on a call is ignored.
