Traffic capacity
General
The traffic capacity of the MX-ONE cordless phone is mainly determined
by the capacity of the ELU31 board and of the MX-ONE and in excep-
tional cases also of the base stations.
The maximum number of ELU31 boards in a media gateway see section
2.2 ELU31 Boards on page 6. For more information of power calculation
and line length see the installation instructions for CORDLESS PHONE.
The maximum number of base stations connected to one ELU31 board
is limited to 8.
Each ELU31 board requires one board position and can be defined to
use 16 or 32 slots with unix style command board_config or will be allo-
cated 16 or 32 slots depending on what is available with board_config
-scan.
The number of slots is equivalent with number of simultaneous call that
can be carried.
Important factors that determine the dimensioning and traffic capacity of
the MX-ONE are:
•
The grade of service (GOS) accepted by the customer. (The GOS
is the probability that a call cannot be made because of congestion
in the system. The customer has to indicate which GOS that is
acceptable. A GOS of 1% means an average of 1 lost call out of
every 100 calls).
•
Portable traffic measured in Erlang.
•
Busy Hour Call Completion capacity for the individual Server, see
the description for CAPACITIES.
•
Highly mobile users also generate extra load without calling, so
called roaming processing.
BS370, not for new delivery.
The BS370 can handle maximum 5 simultaneous calls. This is 3 calls
less than a BS330 or BS340 base station can handle simultaneously.
Each call via a BS370 reduces the maximum number of simultaneous
calls on the host base station with 1 (maximum 8).
