– 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)). This scenario is set by clicking Configure > Network > Roaming and enabling Multi-Frame burst
on the drop-down box (see BSU Screen), 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 Kbps to 108,064 Kbps.
Satellite Mode
All the fields that are common to both the BSU and the SU are applicable here. The SU features two additional fields:
• Base Station System Name (SU only): The name found on the system page of the BSU to which this SU is
connecting. This parameter can be used as an added security measure, and when there are multiple BSUs in the
network and you want an SU to register with only one when it may actually have adequate signal strength for either.
The System Name field is limited to a length of 32 bytes.
If the Base Station System Name is left blank on the SU, it can register with any BSU with a matching Network Name
and Network Secret.
• Scanning Across Bandwidth (SU only): Enable this field if you want the SU to scan across the whole range of
channel bandwidths (5, 10, or 20 MHz) with or without roaming enabled. Disable this field if you wish the SU to scan
only across its configured channel bandwidth.
