5. In the Delivery order row, 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.
6. In the Maximum SDU size (byte) row, type in the maximum allowed packet
size in Bytes (rounded off to nearest 10). The maximum packet size
possible is 1520.
7. 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.
8. If you selected Yes in step 7, select from the SDU error ratio drop-down list
the fraction of a packet allowed to be lost or erroneous.
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 Transfer delay (ms) row, 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.
11. In the Traffic handling priority row, select from the drop-down list which
priority this connection should have.
12. Click Apply.
The new profile is now added, and can be selected from the lists of primary
and secondary profiles when you set up your interfaces.
