Global Asynchronous Stream Packets (GASPs)
Packet rows for GASPs contain these fields in addition to the general packet display
elements listed on page 50:
• Channel Number (ch) — The value of the packet’s channel field. The channel number is
displayed in the bottom half of the field that contains the transaction code.
• Synchronization code (sy) — The value of the packet’s sy field.
• Data Length (data_len) — The value of the packet’s data_length field.
• Header CRC (header_CRC) — The value of the packet’s header_CRC field.
• Data Block Payload (Data) — The Data field can be expanded and collapsed. By default,
it is collapsed, and the value shown is the number of quadlets contained in the packet’s
data block field. When expanded, the actual quadlet data from the data block field is
shown.
• Source Identifier (source_ID) — The value of the packet’s source_ID field.
• Specifier Identifier (specifier_ID) — The value is a concatenation of the packet’s
specifier_ID_hi and specifier_ID_lo field values.
• Version (version) — The value of the packet’s version field.
• Data Block CRC (data_CRC) — The value of the packet’s data_CRC field.
• Idle times (Idle) — The Idle field displays the time between the end of the packet and the
beginning of the next packet.
