General
1.1 Scope
This installation instruction describes the installation and cabling of the
INTEGRATED DECT function, which comprises DECT Extension Line
Unit (ELU31 board), cabling, base stations and how the system shall be
synchronized.
For information about old versions of product please refer to older
version of this document. This document will only handle what is deliv-
ered in this release.
In this document ELU31/3 refers to ROF 137 5412/3 and ELU31/4 refers
to ROF 137 5412/4. If not mentioned specifically ELU31 refers to
ELU31/3 and ELU31/4, all boards are assumed to have latest FW, co
operability is only guarantied between index /3 and /4 of latest FW.
INTEGRATED DECT functionality in the MX-ONE requires a number of
software units (CTLP, CTLMP and CXHH), specific hardware (ELU31
board), external base stations, and portable parts (PP).
The PPs communicate with a base station via radio channels. The chan-
nels are connected from the base station to the ELU31 board through a
cable. The ELU31 board has an integrated switch that can set up switch
paths between the PBX (via the backplane) and the radio channels in the
base station.
In order to secure INTEGRATED DECT functionality, the MX-ONE gate-
ways must be synchronized to one reference timing source. For more
information see chapter 3.4 Synchronization on page 8.
Synchronization ring has one obligation, that all base stations transmit
the air data frames simultaneously. This is accomplished by sending
data on the ring, delay compensated for the delay caused by distance,
