Aprisa XE User Manual
Management and User Ethernet Capacity
The maximum ethernet capacity of an Aprisa XE terminal is dependant on the motherboard version:
Motherboard Version
Maximum Ethernet Capacity
Rev C
32768 kbit/s
Rev D
49152 kbit/s
The maximum ethernet capacity available is the lesser of the maximum ethernet capacity or the available
radio link capacity.
The management ethernet capacity and user ethernet capacity must be identical on both terminals for the
ethernet link to work correctly.
Management Ethernet Capacity
A management ethernet cross connection between the local and remote terminals is created
automatically using the default capacity of 64 kbit/s (connection number = 1). This connection is
essential for remote terminal management communication.
The minimum management ethernet capacity requirement for correct management operation over the
radio link is 8 kbit/s but if the terminal in on a network with large numbers of broadcast packets, the
management may not be able to function.
The management capacity must be set in multiples of 8 kbit/s and the maximum assignable is 64 kbit/s.
User Ethernet Capacity
A user ethernet cross connection between the local and remote terminals is created automatically using
the default capacity of 0 kbit/s (connection number = 2).
The user ethernet capacity must be set in multiples of 8 kbit/s.
The maximum user ethernet capacity available is the maximum ethernet capacity available minus the
management ethernet capacity setting.
To set the management ethernet or the user ethernet capacity:
Enter the required kbit/s in the local terminal capacity field. The associated remote terminal capacity
field will update automatically.
The red numbers, in the mapping connection boxes, are known as connection numbers and are allocated
automatically by the Cross Connections application.
