Connections
The line cord connects to the rear of the M2250 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).
Identical two-prong G3 type connectors are provided on each side of the
console body to permit handset or headset connection at either side of the
console. The M2250 attendant console is compatible with both carbon and
electret handsets or headsets. The electret handset plug is
orientation-dependent and is labeled accordingly.
The attendant console is connected to the system through two digital ports –
one port for Call Service processing and one for Call Destination
processing – with three additional ports for powering, for a total of five ports.
The PCCIU interface used for the PC-based Console software application
requires only three ports in total.
The attendant console requires a Digital Line Card (DLC) or an Integrated
Services Digital Line Card (ISDLC) NT8D02 or later.
