Remember that the professional fraudsters engage in selling international services and can run up very large bills over a short period of time. 5 × 12 trunks = $5,760 worth of international calls over a single weekend via a 24-trunk PBX. 8 PBX Dimensioning The term dimensioning refers to calculating the correct amount of equipment required in a particular situation. The terms sizing, traffic engineering, and engineering refer to the same thing. 1 Number of Extensions The first question concerns the number of telephone instruments to be connected to the system.

The differences are due to dissimilarities in the size of sites, different dates of purchase of the PBXs, and tendering processes. Such a network will require special arrangements to allow the different PBXs to interwork. For example analog to digital converters (A-to-D converters) will be required between analog and digital PBXs. 6). 6: Analog trunk linking analog and digital PBXs. 7). This arrangement is better if you wish to develop your network into an all-digital network at some point in the future.

In the case of a PBX network, this means the individual PBXs (often referred to as the nodes), the inter-PBX trunks, the PSTN trunks, and the extensions. The normal functions of management include resource allocation, fault monitoring, fault localization, and repair. It makes a lot of sense to be able to carry out as much of this work from a single location as possible, so modern PBXs have the possibility of passing alarm information over the signaling network to a maintenance center. It should also be possible to make administrative changes and software updates remotely.
