Sense code A001

The RTP connection failed.

Bytes 2 and 3 following the sense code contain sense-code-specific information.
0003
The setting of the start-of-message bit in a received packet was unexpected. One of the following error conditions was detected:
  • During reassembly of a user message, the byte-sequence-number field of a received packet is set to the next expected sequence number of the user message, but the start-of-message bit is set to one.
  • The byte-sequence-number field of a received packet containing data is set to the expected starting sequence number of a user message, but the start-of-message bit is set to zero.
  • The byte-sequence-number field of a received packet is set to the expected starting sequence number of a user message. The end-of-message bit is set to one, but the start-of-message bit is set to zero.
  • Lower sequence-numbered data was received in an earlier packet with the last-message bit set to one, but the start-of-message bit is set to one in the newly received packet.
0004
The setting of the end-of-message (EOMI) bit in a received packet was unexpected. One of the following error conditions was detected:
  • A packet containing data has the last-message bit (LMI) set to one, but the end-of-message bit is set to zero.
  • During reassembly of a user message, the byte-sequence-number field of a received packet is set to the next expected sequence number of the user message; the last-message bit is set to one, but the end-of-message bit is set to zero.
  • The byte-sequence-number field of a received packet is set to the expected starting sequence number of a user message. The start-of-message bit (SOMI) is set to one, the last-message bit is set to one, but the end-of-message bit is set to zero.
0008
The setting of the last-message bit in a received packet was unexpected. The following error condition was detected:
  • The last-message bit is set to one in a retransmitted packet, but higher sequence-numbered data was received in an earlier packet.
000B
The setting of the "connection qualifier source identifier field present" bits in a received packet was unexpected. The following error condition was detected:
  • The TCID-assignor bit is set to one, but the "connection qualifier/source identifier field present" bits are not set to 01.
000C
The setting of the "optional segments present" bit in a received packet was unexpected. The following error condition was detected:
  • No active context is found, the setup-packet bit is set to one, but the "optional segments present" bit is set to zero.
000D
The setting of the DATA OFFSET/4 in the THDR field in a received packet was unexpected. One of the following error conditions was detected:
  • The data-length field has a value greater than zero, but the payload-offset/4 field points to an offset beyond the end of the network layer packet.
  • The data-length field has a value greater than zero, but the setting of the DATA OFFSET/4 field is not consistent with the encodings of the connection-qualifier/source-identifier field and the optional segments.
000E
The setting of the DATA length field in the THDR of a received packet was unexpected. One of the following error conditions was detected:
  • The data-length field has a value greater than zero, but the DATA OFFSET/4 field points to an offset from which there is insufficient remaining length for the data.
  • The packet contains data, but lower sequence-numbered data was received in an earlier packet with the last-message bit set to one.
000F
The setting of the byte sequence number field (BSN) in a received packet was unexpected. The following error condition was detected:
  • The byte-sequence-number field of a received packet is higher than the next expected sequence number (that is, a new gap in the user data stream is detected), but the last-message bit was set to one in an earlier packet.
0014
The setting of the target resource identifier field present bit of the connection setup segment in a received packet was unexpected. The following error condition was detected:
  • The target resource identifier field present bit in the connection setup segment is set to zero, but target resource identification is required by the receiver.
0016
The setting of the ARB flow congestion control used bit of the connection setup segment in a received packet was unexpected. The following error condition was detected:
  • The ARB flow/congestion control used bit is set to zero, but the use of ARB flow/congestion control is required by the receiving RTP.
0017
A field setting in the topic identifier (X'28') control vector in the connection setup segment in a received packet was unexpected. One of the following error conditions was detected:
  • The topic-identifier field within the topic-identifier (X'28') control vector is not correctly encoded.
  • The topic identifier specified in the topic-identifier (X'28') control vector is not supported.
0018
A field setting in the network identifier (X'03') control vector in a received packet was unexpected. One of the following error conditions was detected:
  • The network-identifier field within the network-identifier (X'03') control vector is not correctly encoded.
  • The network-identifier specified in the network-identifier (X'03') control vector within the connection-setup segment is not the network identifier associated with the receiving RTP.
0019
A field setting in the node identifier (X'00') control vector in a received packet was unexpected. One of the following error conditions was detected:
  • The node-identifier field within the node-identifier (X'00') control vector is not correctly encoded.
  • The node-identifier specified in the node-identifier (X'00') control vector within the connection-setup segment is not the node identifier associated with the receiving RTP.
001E
The setting of the closed bit of the status segment in a received packet was unexpected. One of the following error conditions was detected:
  • The closed bit in the status segment is set to one, but not all reliable data sent to the partner is acknowledged.
  • The closed bit in the status segment is set to one, but data is queued for transmission.
001F
The setting of the ARB level in the ARB segment in a received packet was unexpected. The following error condition was detected:
  • Progressive-mode ARB is specified in the ARB segment, but it is not allowed on this connection.
0022
The setting of the DSEQ field of the status segment in a received packet was unexpected. The following error condition was detected:
  • RSEQ and DSEQ in the status segment are not consistent. The values indicate data not received has been delivered.
0032
The beginning and ending sequence numbers for an acknowledged byte-span pair (ABSP) in a status segment in a received packet were unexpected. The following error condition was detected:
  • The beginning and ending sequence numbers for an ABSP are not consistent either with RSEQ or another ABSP. The sequence numbers overlap.
0033
A field setting in the HPR switching information (X'83') control vector in a received packet was unexpected. The following error condition was detected:
  • The maximum packet size specified in the HPR switching information (X'83') control vector is fewer than 768 bytes.
0035
A field setting in the NCE identifier (X'26') control vector in a received packet was unexpected. The following error condition was detected:
  • The NCE-identifier field within the NCE-identifier (X'26') control vector is not correctly encoded.
0037
Window flow control was requested by the calling RTP but is not supported by the listening RTP.
003A
The using layer terminated abnormally. (This error condition is associated with the RTP user interface and is implementation dependent.)
