As standard, the prefix of the PLL used for downloading to the base stations takes the value
999.
Caution : If there is a link number for the PAD, EBVO, etc. with the value 9x, the system
accepts the value 999 but in this case, the base stations will not switch to
download mode (translation in the analysis tree-structure is finished). In this
case, you should change this value.
The "Base station p0 bit synchronization delay" value must be set to 1.
The SARI number must be defined, and must be the same as the PARI number.
9 Associate cells and trunk groups
A cell must be associated with a single trunk group. A cell is single-cluster.
Use the MMC XBORFA, Object "Base station trunk group", to associate a company profile
and a trunk group number with a cell number. This trunk group is a virtual trunk group and is
used to associate the cell number with a physical equipment interface. For example, cell 0
can be associated with trunk group 0, cell 1 with trunk group 1, etc.
The maximum number of base stations per cell/trunk group is 8 (you are advised to
configure only 6, with a view to expansion in order to increase traffic flow). It may be
necessary to declare several cells. The area to which cells belong is always 0. In multi-site
configuration, if the coverage areas overlap, you are advised to select different cell numbers
for each of the sites (see chapter 13 Multi-site programming).
10 Declare the base stations
Use the MMC XBORFA to declare the base stations.
This MMC is used to associate a trunk group number with a physical equipment interface
number and to determine the type of base station connected.
The line "Mobile recording allowed" must be set to "yes" at system startup. You are advised
to set it to "no" when mobile registration is complete.
Once the base stations have been declared, their software is downloaded. This operation is
performed using TELBOR via the PLL associated with the base station. It takes 10 mn to
download the software to a base station.
The base stations are loaded in groups of no more than 16, and the time taken to load all the
base stations depends on their number.
While downloading is taking place do not run any MMCs other than:
• display status of base stations already created,
• create new base stations.
If the base station does not load, check the following:
• wiring
• remote power supply (40 V or 48 V)
• configuration of the distance between the PBX and the base station, and the type of bus
(short / long if greater than 130 m)
• local data routing, TELBOR.
