maximum of 100 msec. This is to accommodate the periodic transmission of message-oriented performance
reports.
Command and response messages are used to perform various functions, which include the following:
1)
2)
3)
4)
5)
Each message consists of a 16 bit codeword of the form 11111111 0XXXXXX0, which is repeated at least 10 times.
The LAPD message-oriented performance reports are sent across the FDL once per second using the bit-assigned
message structure of Figure 10 on page 24. Each report contains performance data for each second of the previous
four seconds.
