Table 19. Extension Status for Calling Group/CMS Mode
Extension Status LED Status
0 Off
1 Flashing
2 On
In either Hotel or Calling Group/CMS mode, an operator or a calling group or
CMS supervisor with a DLC can change the status of an extension either by
using a programmed button or by pressing the Feature button and dialing a
code. In addition, users in either mode with any type of telephone can change
to Status 1 and Status 2. In calling groups, agents do not change to Status 1. In
Calling Group/CMS mode, users can change sign out of the group by changing
to Status 0; however, in Hotel mode, an extension can be changed to Status 0
only from a DLC.
Considerations and Constraints
The system can be set up for either Hotel or Calling Group/CMS mode but not
for both.
In hotel mode, when DSS buttons are used to monitor status, operators can use
the Message Status button to see whether an operator turned on message
LEDs at the telephones. In Calling Group mode, message status shows
busy/not busy status of the agents.
If a hotel has more than three floors and you wish to have the first digit of the
extensions correspond to the floor number (for example, Floor 5 has extensions
501-520) then you should use a MERLIN II System Display Console with built-in
DSS buttons instead of DSS adjuncts. This is because the DSS buttons on the
MERLIN II System Display Console correspond to the extension jacks instead of
a range of extension numbers, as on the DSS adjunct. A DSS adjunct cannot
have buttons for more than three ranges of numbers. The status of the first 120
rooms is displayed, and if the hotel has more than 120 rooms, Auto Dial buttons
can be assigned to up to 33 line buttons on the console to be used for
Extension Status and for transferring calls to the rooms.
In Hotel mode, the MERLIN MAIL or AUDIX Voice Power outcalling feature does
not work.
