1.1 Scope
This installation planning document will give an explanation of how
different factors influence on the size of the MX-ONE cordless phone
system and how acceptable values can be given to these factors. The
factors that determine the final configuration of a system are:
•
Number of base stations (Radio Fixed Parts (RFPs))
•
Number of portables (Portable Parts (PPs))
•
Traffic requirement for the system
•
Physical nature of the site
•
Choose how the media gateways are synchronized.
Furthermore the system has a number of restrictions that gives limita-
tions to the configuration. These items are explained in the following
sections.
To make a system configuration, first the limitation of the system must
be known, see chapter 2 Limitations in the system on page 6.
The traffic requirements for the system are determined by the number of
portables needed, the estimated traffic generated per portable and the
Grade Of Service (GOS) accepted by the customer. For more detailed
description, see chapter 4 Traffic capacity on page 31.
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 the index /4 and /3 boards, all boards are assumed to have latest FW,
co operability is only guarantied between index /3 and /4 of latest FW.
ELU31/4 has an on-board switch. The switch can be set to “index_3
mode” or “index_4 mode”. This switch must be set to index_3 mode to
have the same functionality as ELU31/3. For PCM synchronization of the
media gateway feature the switch shall be set to index_4 mode. This
feature allows media gateways to receive synchronization from the
ELU31 board.
•
ELU31/4 can replace all other ELU31 versions with some limita-
tions. See section 2.
•
ELU31/4 index_3_mode and ELU31/3 can coexist on the same
ring.
•
ELU31/4 index_4_mode can distribute PCM synchronization to all
media gateways with the DECT synchronization ring. See chapter
