Continuous stands for continuous retransmission. The back off random mask (random
amount of time waiting for retransmission) can be configured between 2 1 x 51.2 (slot
time) to 2
10
x 51.2 (slot time) ms.
Force collision can be activated when receiving packets. In addition to normal capture
operation, forced collisions can be generated at the receive end of 10/100 module ports,
but only when the port is in half duplex mode. The collision takes the form of a number
of nibbles generated at a specific offset within a packet. A number of consecutive
collisions are generated, followed by a non-colliding period. Please not that module
card XM-22R4 does not support force collision/late collision yet.
4.9.1.9. BERT
Please note that module card XM-28L1 only supports BERT on layer 1 and module
card XM-22R4 and XM-23R2 support BERT on layer 2. Choose the appropriate type by
clicking the radio button and input an offset value for test. The offset value should be
always at least 14 or larger. The settings of BERT in Set up Transmit Packet must be
exactly the same with the settings of BERT in Set up Receive Packet. If the settings
do not match, BERT error would occur.
