TANDEM CONFIGURATION
Definition
This document describes the interaction between two
telephones ( wired-cordless or wired-wired ) working
together as a unit.
Use
Users with a "master telephone" (e.g. a wired phone
on the desk) and a "slave telephone" (e.g. portable
phone) in a TANDEM configuration are treated as 1
logical unit.
This feature enhances the communication for users
that, for example, have a wired phone on their desks
and need to be mobile within their company’s building
having their own portable.
"The TANDEM operation
makes the wired telephone mobile"
Operation
General
The TANDEM configuration is a unit, consisting of two
telephones using the same directory number. One of
the telephones is defined as the "master" and the other
one as the "slave".
Numbering plan and categorisation
Each directory number is independent with it’s own
parameters and COS (=Class Of Service).
If two directory numbers are working together as a
unit, one has to be defined as a master and the other
one as a slave.
Both telephones of the unit can be reached via the
telephone number of the master (= the common
directory number).
To keep up flexibility with different parameters and
COSs, from the programming point of view, both
master and slave are treated independent.
If the slave is assigned to a master, the slave is not
reachable any more via it’s own directory number.
(This directory number and the related administrative
data is hidden in the internal directory.)
The common directory number is always shown:
• On the LCD of the slave
• On the CIL records in case of active calls
from the slave
• On the display of the called party in case
of a calling slave
• In the A-number.
Traffic conditions
When during logon at least one of the two phones is
busy, the common directory number will be marked as
busy.
The following table shows how a call to a busy
common directory number will be announced,
depending on the logging case:
