    Base Station. The DCT1900 system can be configured to meet user requirements with respect to the area to be covered and the number of Portable Telephones to be used. This system has been designed to operate in indoor/ outdoor environments and can support both low as well as high traffic density situations.

  • Page 23: System Overview

    Portable Telephone user can be on a call while moving from the radio coverage area of one RE to the radio coverage area of another RE without any disruption to the call. In the case of roaming in a DCT1900 Mobility configuration, a Portable Telephone can originate or accept a call in the radio coverage area of any RE.

  • Page 27: Operational Concepts

    Operational Concepts Operational Environment The DCT1900 is designed for mobility within the defined coverage area of the system. If the defined coverage area of one system is too small, then in conjunction with the MS, several DCT1900 systems can be connected together to act as if they were one large system.
  • Page 28 System Description, System Overview System Architecture The DCT1900 system provides a wireless infrastructure between the user and the MS/PBX. The system can serve multiple users at the same time. The system can be split up in a fixed part (made up of one RE and multiple Base Stations) and many Portable Telephones.
  • Page 29 If all requirements are met, the registration will succeed. Note that this dynamic behavior means that only at this point will a Portable Telephone be registered in a system. There will never be a fixed relation between a system and a PUN! Registration Failures The registration process may result in a rejection from the RE/MS.
  • Page 30 (PSAA). The algorithm uses the authentication key that is downloaded over the programming cable into the Portable Telephone during initialization. In a DCT1900 Mobility Server configuration for performance reasons, a session key (temporary key, reissued at registration time) will be stored locally in the RE as the result of a registration, to allow authentication without consulting the MS during call establishment.

  • Page 31: Roaming And Handover Handling By The Portable Telephone

    (another Base Station of another RE) and location updates (roaming). 2.2.1 Unlocked Situation When the Portable Telephone is first turned on, it will regularly scan the air interface. As soon as the Portable Telephone detects a bearer signal from a Base Station, it will lock to this bearer. A bearer is an active PWT air interface channel in which transmissions take place.
  • Page 32 Technical Product Manual - DCT1900 System Description, System Overview System Status A Portable Telephone contains a list of the current RE status. For each system, the status may be: NOT_ALLOWED: TEMP_NOT_ALLOWED: ALLOWED: Roaming If the Portable Telephone is locked to a certain Base Station, two types of roaming are supported: voluntary roaming, when a better bearer is available, or forced roaming, when the current bearer is no longer valid.

  • Page 33: User Functions

    If a good bearer cannot be found within the current RE, alternative systems will be investigated in the history list. If no RE is found, the Portable Telephone quickly scans its environment to find a valid bearer. If a bearer is found and the network has not yet cleared the call, the Portable Telephone continues to scan its environment.

    Allows the user of the Portable Telephone to cut voice communication with an ongoing call without actually disconnecting it. Reconnect Call A call that is put on hold by the user of the Portable Telephone can also be resumed from the same Portable Telephone. Callback If the called number is occupied and hard to reach due to busy line, this feature registers the target extension to automatically call back when it is free.

    Other System Aspects Installation 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.

    HAPTER Base Station Planning The major task in configuring a DCT1900 system is defining the number of Base Stations required to cover an area to a satisfactory level. This Chapter describes how a Base Station plan can be made in order to gain full area coverage. Chapter 5, Paragraph 5.2 explains how traffic requirements additionally influence the number of Base Stations.

  • Page 116: Departmental Differences

    Technical Product Manual - DCT1900 Configuration Directions, Base Station Planning X–ray rooms in hospitals protected by lead walls, computer rooms in banking buildings protected against unwanted interference, etc. do not allow radio signals to enter. Exhibition halls or production halls may give reflections due to huge metal structures. This causes interference which reduces the capacity and coverage area per Base Station.

    Install a Base Station in the middle of the "typical area" and power the Site Survey Tool. Switch a Portable Telephone to DCA mode and set up a call. Walk away from the Base Station in one direction. Also enter rooms with the Portable Telephone switching to your left and right hand.

The maximum permissible length depends on the wire size and the number of pairs used between the MDF and Base Station.

    When using the PBX option refer to the PBX supplier and/or PBX documentation to assure that the PBX power supply matches the worst case power requirements of the DCT1900 system. The external source must supply –48Vdc, which may be connected to the backplane for powering the system boards and directly to the MCCB for powering the Base Stations.

It is possible to check the status of a system board and its peripheral circuits in the Radio Exchange window of the CSMW.

  • Page 363: Individual User Complaints

    Individual user complaints point to parts in the system that can only be accessed by that particular Portable Telephone. These parts are the Portable Telephone itself, the charger, etc. Unlike faults, for instance in Base Stations or system boards, which affect more than one user and mostly cause error reports, these types of faults cannot be detected by the system simply because of their nature.
