    Ascotel® DECT System Ascotel® DECT System One or more radio units are required to be able to operate DECT handsets on the Ascotel® IntelliGate® system. They are connected to one or two AD2 interfaces. They are powered either via the AD2 or locally using separate plug-in power supply units. Office handsets as well as GAP-mode DECT handsets by outside manufacturers can be logged on to a radio unit.

  • Page 8: Planning Dect Systems

    Ascotel® DECT System Planning DECT systems The following sections take you through the planning procedure for an Ascotel DECT system (DECT: Digital Enhanced Cordless Telecommunications). It contains recommendations on the project sequence and on handling the measuring equipment. Unless otherwise specified, these considerations apply to DECT radio units operated with the integrated antenna.

  • Page 9: Ascotel Dect And Pbx

    Ascotel® DECT System System installation Once determined, the locations must be observed precisely in order to obtain reproducible results. There are always surprising effects in practice, due for example to cells being set up with several radio units (rather than the one cell originally planned and surveyed).

  • Page 10: Coverage Area

    Ascotel® DECT System Coverage area The supply range of an Ascotel DECT system can include many different types of geographic geometry. In most cases the bulk of the supply range is inside buildings. A DECT system always relates to a PINX (Private Integrated Exchange) in a PISN (Private Integrated Services Network).
  • Page 11 Ascotel® DECT System Topology A radio system supplies a specific area. This area is known as the supply range. In practice home users are able to receive a variety of autonomous DECT systems (e. g. Ascotel DECT, cordless DECT phones, etc.). An Office handset can be logged on in up to four autonomous DECT systems.
  • Page 12 Ascotel® DECT System Location areas Location areas are used to divide the radio area into as many as four locally subdivided supply ranges. The system knows the location area in which a handset is located and only needs to send messages to the handset within that location area. Location area partitioning helps to reduce the system load caused by the signalling of incoming calls.

  • Page 13: System Characteristics

    Ascotel® DECT System System characteristics 3.3.1 Radio characteristic of a radio unit The coverage range of a radio unit depends among other things on the antenna through which the radio signal is transmitted. The radio units transmit through two integrated antennas inside the housing. The radio characteristic of internal antennas is virtually spherical (with only transmission to the rear slightly diminished), in other words registered handsets are able to move away from the radio unit the same distance in every direction without the radio signal breaking up.

  • Page 14: High-Frequency Propagation Conditions

    Ascotel® DECT System Fig. 6: Radio characteristic through obstacles to radio propagation 3.3.2 High-frequency propagation conditions For a better understanding of the explanations on physical conditions given in the following sections, we first need to take a look at the basic principles of high- frequency propagation.
  • Page 15 Ascotel® DECT System • Interference due to other radio signals, leading to transmission errors The receive power of DECT signals can fluctuate a great deal, locally, within only a few centimetres (see Fig. 7). This means that signal interference can be reduced or eliminated simply by altering the position.
  • Page 16 Ascotel® DECT System Obstacles may include: • Moving metal objects such as lifts, cranes, carriages, escalators, blinds, especially ones that are actuated automatically (the influence of such obstacles varies and is therefore difficult to assess) • Metal-panelled rooms and large metal-clad objects such as air conditioners, computer rooms, metallized glassed areas (mirrored), fire protection walls, storage tank installations, refrigerating units, boilers •...

  • Page 17: Using External Antennas

    Ascotel® DECT System Reception conditions Optimising range is a fundamental challenge of radio technology. The reception of information in marginal zones is patchy at best. Practical measurements are carried out on the premises to determine the range. When instructing users, the following instructions can help to achieve optimum results: •...
  • Page 18 Ascotel® DECT System Radiation pattern in relative field strength Horizontal Vertical Fig. 10: Example 1: Omni-directional gain antenna The second example of an antenna, which radiates directionally both horizontally and vertically, is called a corner reflector antenna. It is ideally suited for covering distant remote buildings or areas.
  • Page 19 That is why the radio units themselves are always equipped with two internal antennas. For recommendations regarding manufacturers and antenna type please contact Support ( https://pbxweb.aastra.com) Note: If two individual antennas are used instead of a dual antenna, the installation clearance between the antennas must not be chosen at random but adapted to the wavelength of the radio signals.

  • Page 20: Using Repeaters (Relays)

    Ascotel® DECT System 3.3.4 Using repeaters (relays) Repeaters are autonomous devices which increase the range of the DECT system. When positioning a repeater you need to make sure not only that the coverage ranges overlap but also that the repeater is mounted in the coverage range of one radio unit and vice versa.
  • Page 21 Most repeaters do not support voice data encryption. For this reason the "Encryption" parameter should normally be configured to "No" in the DECT System Configuration. For recommendations regarding manufacturers and a suitable repeater type please contact Support (https://pbxweb.aastra.com). Planning DECT systems...

  • Page 22: Planning

    Ascotel® DECT System Planning In practice a regulated procedure for planning has proved sensible and, above all, efficient. A considerable increase in efficiency can be achieved through the consistent use of the aids available. In the following, the planning procedure is described in the form of a "checklist": 1.

  • Page 23: Initial Rough Determination Of The Radio Unit Locations

    Ascotel® DECT System 3.4.2 Initial rough determination of the radio unit locations Radio circumstances are difficult to estimate. For this reason, situations regarded as particularly critical need to be determined on site through measurements. This will provide a reliable idea of the equipment required and the locations for the radio units.

  • Page 24: On-Site Measuring

    Ascotel® DECT System 3.4.3 On-site measuring As soon as the concrete locations for the radio units have been planned, it is recommended to confirm the circumstances in keeping with the plan using on-site measurements.

  • Page 29 Ascotel® DECT System Handover overlap areas • To guarantee a clean handover, the radio units should be fitted in such a way that the 35–40 dBµV limits are at least in contact. • When conducting survey measurements in unfinished buildings, the limits should be increased by 10 dBµV.
  • Page 30 Ascotel® DECT System Location areas Up to 4 location areas can be configured in an Ascotel® DECT system. With incoming calls each handset is called by the system simultaneously via all the radio units of a location area in which the handset is logged on. As the capacity of the signalling channel is limited, splitting the radio units into several location areas needs to be considered in the following cases: •...
  • Page 31 Ascotel® DECT System Traffic density Once the supply range has been located and covered, the locations for the radio units are known. The second phase now looks at other requirements: The traffic volume, determined by the number of handsets and the frequency and duration of connections in an area defined by the customer.
  • Page 32 Ascotel® DECT System Hotspots A hotspot is an area with an above-average number of handsets. Such an area can be covered with several radio units as the resources in the coverage range of neighbouring radio units are cumulated. It is recommended to cover hotspots with several SB-8 (or SB-4+) radio units as they operate in ”Zero-Blind-Slot mode”...
