•Meridian 1 Attendant PC: Software User Guide
Feature description
Attendant consoles are designed to assist in placing and extending calls into
and out of a telephone switching system. The console is operated by an
attendant who is the human interface between the system and the users.
Several types of attendant consoles are designed for telephone traffic control
in the Meridian 1. Each provides attendants with specialized features that
increase the speed and ease of call processing.
This document describes the M1250 and M2250 attendant consoles, and the
Meridian 1 Attendant PC Software application. The M1250 and M2250
consoles are functionally compatible with the QCW4 Attendant Console.
• The M1250 is designed to work in analog mode and functions through an
analog line card when connected to a digital switch. Its cabling schemes
are compatible with those of the QCW4 console.
• The M2250 is a digital version of the M1250, offering additional
features. A digital line card connects the M2250 to the Meridian 1. It has
a modified cabling scheme.

553-2201-117 Standard 10.00 January 2002
• The Meridian 1 Attendant PC Software application allows all functions
supported by the M2250 to be performed on a computer workstation
using a mouse pointing device or keyboard within a Windows 5®
operating system environment. The M2250 attendant console is not
required to run the Meridian 1 Attendant PC Software application. Refer
to the Meridian 1 Attendant PC: Software User Guide for more
information on Meridian 1 Attendant PC Software.
