POINT TO POINT / POINT TO
MULTIPOINT T0
DEFINITIONS
Point to Point link: a Point to Point link is a digital access to the public network used exclusively by
Alcatel OmniPCX Office. The TEI settings are generally fixed, as there is only one terminal (Alcatel Om-
niPCX Office) for this access, but they can also be dynamic.
Point to Multipoint link: a Point to Multipoint link is a digital access to the public network shared by
several terminals. In this type of configuration, each terminal is identified by its TEI and dedicated DDI
sequence. The TEI management mode can be fixed or dynamic, depending on the public operator.
Both types of link can be supported simultaneously on the same system. The TEI management mode
(fixed or automatic) is configured separately for each access.
Example of the environment
This example illustrates both connection types: Point to Point and Point to Multipoint.
