active SFC is limited to send a single data message. Total throughput available to remaining best effort
traffic is around 76% of the maximum available throughput.
• Multi-Frame burst support – The system will enable Multi-Frame burst for all SFCs, but the maximum
number of data messages sent in a burst will be defined by the parameter “Number of data messages in
a burst” for each of the SFCs (see “Service Flow Class (SFC)”
on page 30). This scenario is set by
enabling Multi-Frame burst on the drop-down box of the Configure, Network, Roaming sub-tab (see
“BSU Screen”
on page 52) and disabling Automatic Multi-Frame Bursting (this parameter).
The maximum number of data messages in a burst directly influences the total throughput of the system.
Typical values are:
No. of messages in a burst: % of the maximum throughput:
4 100 %
3 97.6 %
2 92.9 %
1 76.2%
• Automatic Multi-Frame burst support – The system will continuously be monitoring which of the active
SFCs has the highest priority and dynamically enable Multi-Frame burst for the highest priority SFC only,
keeping all the lower priority SFCs with Multi-Frame burst disabled. If there are multiple SFCs having the
same, highest priority, all of them will have Multi-Frame burst enabled. The maximum number of data
messages sent in a burst is defined by the parameter “Number of data messages in a burst” and it can be
different for each SFC (see “Service Flow Class (SFC)”
on page 30). This scenario is set by enabling
Multi-Frame burst on the drop-down box of the Configure, Network, Roaming sub-tab (see “BSU
Screen”
on page 52) and enabling Automatic Multi-Frame Bursting (this parameter). In this case, even
the lowest priority SFC will have Multi-Frame burst dynamically enabled as long as it is the only SFC in
the system that has traffic. By default, configuring even a single high priority SFC with automatic multi-
frame bursting enabled will decrease throughput of low priority best-effort traffic to approximately 76% of
maximum available throughput, because low priority traffic will have Multi-Frame burst disabled to
optimize bandwidth for the high priority traffic.
Registration Timeout
This is the registration process time-out of an SU on a BSU. Default is 5 seconds.
Network Secret
A network secret is a secret password given to all nodes of a network. An SU can only register to a BSU if it
has the same Network Secret. The Network Secret is sent encrypted and can be used as a security option.
Input / Output Bandwidth Limit
These parameters limit the data traffic received on the wireless interface and transmitted to the wireless
interface, respectively. Selections are in steps of 64 Kbps from 64 to 108,064 Kbps.
