Overview
The integrated DECT is meant to be used on NeXspan PBXs earlier than R5.1 and on Aastra X
series PBXs.
The DECT system contains the following items:
•
The mobile terminal which gives the user access to PBX telephony features
•
the base station which provides radio coverage for a given area and supports four
simultaneous calls. In addition, the base stations are equipped with "antenna diversity", a
feature that ensures optimal reception quality within the coverage area. The number of radio
base stations used depends on the size of the coverage area and the level of traffic
supported. Only after carrying out a site radio survey is the number of base stations
determined, to ensure complete coverage for each site. Connecting a DECT base station to
an S0 access voids the possibility of connecting any other ISDN equipment via the same
access (point-to-point bus).
•
DECT interface card: the base station is connected to the PBX via an S0 link for 2-channel or
4-channel base stations.
