6. In the Delivery order field, select from the scroll list whether or not data
should be delivered in the same order it was sent. Yes means the data
packets are delivered in the same order they were sent.
7. In the Maximum SDU size (byte) field, type in the maximum allowed packet
size in Bytes (rounded off to nearest 10). The maximum packet size possible
is 1520.
8. Select from the SDU error ratio drop-down list the fraction of a packet
allowed to be lost or erroneous. Only used if you select Yes in step 10.
9. Select from the Residual bit error ratio drop-down list the undetected bit
error ratio of a packet. If no error detection is requested, Residual bit error
ratio indicates the bit error ratio in the delivered packets.
10. In the Delivery of erroneous SDUs row, select one of the following from the
list:
• Yes means packets are allowed to contain errors. This setting is suitable
for delay-sensitive transmission, because the need for retransmission is
limited. The SDU Error settings in step 8 and step 9 will apply.
• No means packets are not allowed to contain errors, and the SDU Error
setting in step 8 will not be applied. This setting is suitable where
error-free transmission is important and delays are accepted.
• No detect means that errors will not be detected, and the SDU Error
setting in step 8 will not be applied.
11. In the Transfer delay (ms) field, type in the delay in ms. This is the delay
from the time data is received in the terminal until it arrives at the receiving
end.
• If the Transfer delay is 500 ms, error correction is disabled.
• If the Transfer delay is 4000 ms, error correction is applied.
12. In the Traffic handling priority row, select from the drop-down list which
priority this connection should have.
