This read-only object contains a raw copy of the X.25 packet that triggered the error event (when available), allowing detailed analysis of what data was malformed or caused the problem. Network engineers and vendor support teams examine this packet dump to verify whether the error was caused by corrupted frames, out-of-sequence packets, or invalid protocol headers. For example, the value might be a hexadecimal string like "0x010203..." representing the first 128 bytes of the problematic packet.
