Description of the System
The elmeg DECT300 System is a DECT base station with an integrated controller for use
with up to 8 »elmeg DECT handsets«. Connect the base station to an elmeg PABX sys-
tem equipped with up to 8 analog ports using an installation cable.
An analog port is permanently assigned to each handset that is logged in to the system.
If 8 handsets are logged on at the base station the base station must also be connected
to the PABX system via 8 analog ports. The base station analog inputs are electrically
isolated from the telephone system.
Display of the caller's number (CLIP) is only possible with elmeg PABX systems, To utili-
ze this function there must be a serial link (RS232 / V.24) between the PABX system and
the base station. You can use the »elmeg DECT V.24 CLIP cable set« for this connecti-
on, or the programming cable for the base station.
To ensure reliable transmission of CLIP data, the distance between the base station
and the PABX system should not exceed 50 meters.
The range of the base station can be extended using a maximum of 6 »elmeg DECT re-
peaters«, with a maximum of 3 repeaters arranged in series. Each repeater extends the
range by a further 25-300 m, while taking into account that the cells must "overlap".
The base station provides six simultaneous speech channels (simultaneous calls), a re-
peater only two. Repeaters are therefore used primarily for extending the range of the
system and not for providing more speech channels. If a channel is occupied in a repea-
ter cell, a channel is likewise occupied at the base station.
The system may only be connected at internal, analog ports of PABX systems. All
settings for the base station are preconfigured for analog connection to elmeg
PABX systems (e.g. flash time, a/b adaptations, etc.). No modifications or adapta-
tions are required.
With elmeg DECT300 systems, please use »elmeg DECT handsets« only, as other
handsets may not be supported.
Positioning of a Base Station or Repeater
The DECT transmitting/receiving range extends out in circular form around the base sta-
tion, with a radius of around 25 - 300 m. Radio propagation depends greatly on the am-
bient conditions and structures. For example, steel reinforced concrete walls and cei-
lings restrict radio propagation considerable, whereas lightweight structures, or even
masonry walls allow for greater DECT propagation. To ensure optimal radio propagation
position the base station such that the greatest possible number of rooms lie within the
immediate range. You should determine the best possible location prior to installing the
base stations permanently. You can do this by conducting calls between two handsets
and testing the reception at various locations.
Intendend Use
The elmeg DECT 300 is a cordless, multi-cell DECT system for analog connection to el-
meg PABX systems equipped with a CLIP function.
