operator) - refer to the User Manual, Services for PBX Operator, Chap. Disa Service.
Paging
A system similar to the broadcasting one which looks for and advises subscribers
equipped with key (system) telephone sets.
ISDN
A digital public network operated by PTT that provides high-quality voice and data
services. It allows, for example, to use DDI from the public telephone network to an
internal subscriber. The ISDN module for the 2N OMEGA LITE PBX is available to
you.
Internal Subscriber Groups
The 2N OMEGA LITE PBX allows to define two internal subscriber groups that can
behave as if they had 2 independent (virtual) PBXs. Each group can
•
have a PBX operator of its own;
•
have a fax and answering and recording machine of its own (unless it uses 2N
OMEGA LITE voice mail);
•
have a DAY / NIGHT mode of its own (independently of the other group);
•
keep its telephone call costs separately;
•
have an 2N DOOR COMMUNICATOR doorlock system of its own;
•
have their own CO lines, etc.
Department
Internal subscribers that are part of an organizational unit (such as department,
division, etc.). Departments are fully independent of groups. The PBX defines up to
6 departments with numbers 10, 20, 30, 40, 50, and 60. Each internal subscriber
can be part of one or more departments, but of one group only.
