The MTS provides the interface between the mobile stations within the Dimetra IP system and
the rest of the system infrastructure. The main functions of the MTS are:
•
•
•
•
•
•
•
•
•
There are two different versions of MTS:
•
•
MTS 2 is the smaller of the two versions and supports one to two Base Radios. MTS 4 is the larger of the
two versions, and with the expansion cabinet installed, it supports one to eight Base Radios.
MTS 2 and MTS 4 are built up inside cabinets. The MTS cabinets comprise card cages (the same card
cage is used in both MTS 2 and MTS 4), which in turn house different configurations of modules, for
example, Power Supply Units, Base Radios, and Site Controllers. These modules provide the MTS's
functionality. Different configurations and number of modules determine the MTS's functionality and
capacity. Each of these modules is described in more detail in this manual.
The MTSs are managed by the system infrastructure's Network Management (NM) applications.
Communication between the MTSs and the NM applications takes place through an X.21 or E1
link. Through this link, the NM applications can download new configuration files to the MTSs
and receive alarm/event and performance statistics from them.
For information regarding network management configuration of the MTS, please refer to the MTS
Site Object sections of the Zone Configuration Manager manual and Online Help.
