Summary
The Summary tab displays the summary screen listing the major bytes of the received SONET signal.
Column #1 - Indicates the byte type
Column #2 - Provides the hexadecimal value of the byte (if applicable)
Column #3 - Provides a byte decode (Please refer to the byte definitions for an explanation of the
listed bytes)
For Path traces, (SP) indicates a space between the message characters.
The message will be displayed in red when an alarm condition is detected. In the example below, the C2 byte
