Sense Data
800A Too-Long PIU. Transmission was truncated by a receiving node because the
PIU exceeded a maximum length or sufficient buffering was not available.
800B Incomplete TH. Transmission received was shorter than a TH.
Note: It is usually not possible to send a response for this exception
condition because information (FID, addresses) required to
generate a response is not available. It is logged as an error if this
capability exists in the receiver.
800C DFC Error. Data Count field inconsistent with transmission length.
800D Lost Contact. Contact with the link station for which the transmission was
intended has been lost, but the link has not failed. If the difference between
link failure and loss of contact is not detectable, link failure (X'8002') is sent.
800E Unrecognized Origin. The origin address specified in the TH was not
recognized.
800F The address combination is invalid.
8010 Segmented RU Length Error. An RU was found to exceed a maximum length or
required buffer allocation that might cause future buffer depletion.
8011 ER Inoperative or Undefined. A PIU was received from subarea node that does
not support ER and VR protocols and the explicit route to the destination is
inoperative or undefined.
8012 Subarea PU Not Active or Invalid Virtual Route. A session-activation request
for a peripheral PU or LU cannot be satisfied because there is no active SSCP–
PU session for the subarea node providing boundary function support, or the
virtual route for the specified SSCP–PU (type1 or type 2 nodes) or SSCP–LU
session is not the same as that used for the SSCP–PU session of the type 1 or
type 2 node's PU or the LU's subarea PU.
8013 COS Not Available. A session activation request cannot be satisfied because
none of the virtual routes requested for the session is available.
8014 Reserved.

8016
8017 PIU from Adjacent Pre-ER-VR Subarea Node Rejected. A PIU that requires
intermediate path-control routing was received by a subarea node from an
adjacent subarea node that does not support ER–VR protocols, but the
receiving subarea node does not support intermediate path-control routing for
adjacent subarea nodes that do not support ER–VR protocols.
8018 Management Services component is unable to find or recognize the name of the
application transaction program specified in the request.
