Figure 3: Example of a minimum of roaming and hand over traffic.
ELU31 has 32 B-channel configuration.
3.4.2
High call traffic configuration
In this example there is double base station coverage such that more
B-channels are available for high call rate reasons in specific areas, see
figure 4 Example of a high call configuration. ELU31 has 32 B-channel
configuration. on page 14.
Note:
The number of ELU31 boards should not be over dimensioned
without reason as it causes unnecessary load that may adversely
affect portable performance.
Note:
In a configuration that maximise number of base stations to
reduce the number of external hand over and roaming events.
Can increase the number of connection hand over events done
on the board in a high mobile environment. Each connection
hand over event will use 2 B-channel temporarily.
