MIVOICE 4224 OPERATOR (DBC224) FOR MIVOICE MX-ONE

1 GENERAL
1.1 INTRODUCTION
Welcome to the Directions for use for MiVoice 4224 Operator, hereafter called the DBC
224 PBX operator console. The MX-ONE uses a combination of advanced digital tech-
nology, ISDN communication principles and distributed stored program control which
make MX-ONE the perfect choice for organizations that know the value of fast and
precise system information handling.
This guide will demonstrate how the PBX operator console helps PBX operators to
handle the functions of the exchange.
1.2 GLOSSARY
For a complete list of abbreviations and a glossary, see the description for ACRO-
NYMS, ABBREVIATIONS AND GLOSSARY.
1.3 DIFFERENT APPLICATIONS
The MX-ONE can offer different configurations to meet the customer's needs. The PBX
operator can be set up to work in the following environments:
• In a stand alone exchange
• In a private network
• Serving a customer group
1.3.1 IN A STAND ALONE EXCHANGE
The PBX operator handles all traffic from/to the PBX operator in a stand alone
exchange.
1.3.2 IN A PRIVATE NETWORK
In a CCS network environment with more than one exchange, the PBX operators can
be set up in the following ways:
• The PBX operator(s) can reside in one exchange and handle all traffic from/to
the PBX operator(s) for the entire private network.
• The PBX operator(s) can reside in different exchanges and handle all traffic
from/to the PBX operators for the entire private network.
Either the PBX operator(s) are assigned in one exchange or several exchanges,
the services are transparent to customers.
• Centralized-Operator (C-OP), PBX operator services can be centralized, by
re-directing the operator traffic from an exchange to another exchange"s oper-
ator(s).

GENERAL
1.3.3 PBX OPERATOR AND CUSTOMER GROUP
If the Customer group function is used, the PBX operator can serve a number of
customers. The PBX operator can either be common for all customers or each
customer can have a PBX operator of their own.
1.3.4 CUSTOMER CENTRALIZED PBX OPERATOR
In an ISDN network environment with more than one exchange and where the
Customer group function is used, each customer can have a centralized operator of
their own, that is a customer centralized operator (CC-OP). The customer centralized
operator has higher priority than C-OP in serving calls to a PBX operator.

3 PREPARING THE CONSOLE
3.1 PRESENT MARKING
Present marking allows the console to accept calls.
3.2 ABSENT MARKING
Absent marking stops the exchange from presenting calls to the console. (Presenting
individual operator calls to an absent marked OPI is optional.)
Note: When a console is present marked and a presented call is not answered within
a pre-defined time, the console will be automatically be marked as absent. In 1.5
field OFF DUTY lights. BLOCKED lights if your console is blocked manually.
3.3 NIGHT SERVICE
If all consoles are in the state of absence, the exchange is switched to night service.
The OFF DUTY extinguishes and the NIGHT SERV. lights.
When an exchange is in the state of night service, present marking of at least one oper-
ator console will switch the exchange to day service. The NIGHT SERV. extinguishes.
The MX-ONE can provide the exchange day/night status control function. It gives some
services or features different characteristics in a night switched exchange than in a day
switched, for example, toll restriction/TCD category, and re-direction destination
numbers for calls to common operator from internal parties.
The exchange day/night status can be specified by a procedure from a PBX operator
console or automatic on time according to a pre-defined time schedule. If the exchange

20/1553-ANF 901 54 Uen F3 2016-03-14 20
PREPARING THE CONSOLE
status is not specified by the following procedure, neither automatic on time nor the
operator presence/absent status will determine the exchange day/night status.
3.4 SELECTION OF FUNCTIONS
