MERLIN LEGEND Communications System Release 5.0
Feature Reference 555-650-110
Features
Direct-Line Console
Lines that are not assigned to buttons on the DLC can be selected by the operator
only by dialing the pool dial-out code from the SA button or, on an MLX DLC, by
selecting a DSS button for the pool dial-out code.
Lines that are not assigned to a pool cannot be selected from a DLC unless they
are assigned to buttons on the console. Shared SA buttons cannot be assigned to
DLCs.
Key and Behind Switch Modes
Only DLCs (not QCCs) are allowed in Key and Behind Switch modes.
A DLC operator cannot select lines that are not assigned to buttons on the
console.
Telephone Differences
MLX Telephones
An MLX-20L assigned as a DLC can also be used for system programming by
connecting it to any of the first five extension jacks on the first MLX module and
designating the extension jack for system programming. The Home screens of the
MLX-20L and MLX-28D are the same as those of non-operator telephones.
The built-in DSS field on the MERLIN II System Display Console corresponds to
physical extension jacks in the control unit instead of specific extension numbers
in the numbering plan. Therefore, DSS buttons on the MERLIN II System Display
Console cannot be used to monitor the busy status of pools or calling groups.
All Dial 0 calls are directed to the QCC queue and do not ring at any DLC
positions. A DLC cannot use Position Busy, which is only for QCCs. A DLC cannot
be assigned as a position-busy backup for a QCC (only calling groups can provide
backup for a QCC).
Analog Multiline Telephones
An analog DLC cannot be used for system programming.
