Connections

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 TNs
(primary and secondary) with two additional TNs for powering. Two
additional units may be used for long line loop powering.
The M2250 console requires a Digital Line Card (DLC).
