M2250 Attendant Console
The line cord connects to the rear of the attendant console through a 25-pin
subminiature D-type connector. The jack connector is attached to the line
cord for user safety and equipment protection (pins are not exposed). Having
the plug connector mounted in the console also prevents interchanges
between the line cord and the serial data port connectors (the serial data port
in the console has a jack connector).
A two-prong G3 type connector is provided on both sides of the console body
to permit handset or headset connection at either side of the console. The
attendant console is compatible with both carbon and electret handsets. The
electret handset plug is orientation-dependent and is labeled accordingly.
The M2250 attendant console is connected to the system through two TCM
loops (primary and secondary) with two additional units for powering. Two
additional units may be used for long line loop powering.
The M2250 console requires a Digital Line Card (DLC).
The display screen contrast on the attendant console can be adjusted using the
Contrast option on the Options menu.
The pitch and volume of the buzz tone on the console can be adjusted by the
user.
You can choose any one of eight languages (English, French, Spanish,
German, Italian, Norwegian, Gaelic, or Turkish) for the console screen
displays.
The attendant console is equipped with a real time clock/calendar. The time
of day (hours, minutes, and seconds) and the date (day, month, and year) are
displayed on line 1 of the display screen.
The user can turn the sound of key click on or off. On the M2250, the user can
adjust the pitch and volume of the key click.
The Busy Lamp Field/Console Graphics Module (BLF/CGM) can be added
to an M2250 attendant console.
