Other System Aspects

5.1Installation and Maintenance

As each DCT1900 system is configured to meet specific user requirements, the RE must be assembled on location. The system must be initialized after the physical installation. DCT1900 system initialization, maintenance and updating, and fault finding and repair are accomplished with the aid of the CSMW Software program running on a personal computer.

Automatic System Maintenance is a built–in feature that will detect, report, isolate, and when possible, recover the system from errors.

All of the system boards in the RE have a number of light emitting diodes that enable maintenance personnel to quickly localize a faulty board. This feature is applicable during the power–up phase and operational use of the system.

5.2Statistics

The CSMW software is capable of collecting statistical information. During operational use of the DCT1900 system, useful information can be registered. This information can consist of the total call time of all Portable Telephones per hour during a day or a period of days, highest number of simultaneous calls, call duration per user, distribution of calls according to the call length, load of Base Stations, status information of a call, handovers, etc. All this information is useful to analyze the performance of the DCT1900 system.
