ATM network-generated cause and diagnostic codes

ATM network-generated cause and diagnostic codes are issued in some messages when a request for activation of a native ATM permanent virtual channel (PVC) or a switched virtual channel (SVC) fails. These codes provide information about the cause of a failure detected by the ATM network.

This topic shows possible codes and their meaning.

Note: The codes included in this topic are those defined by the International Telecommunication Union–Telecommunication Standardization Sector (ITU-T), as specified in the ATM User-Network Interface Specification, Version 3.1 , published by the ATM Forum. If you cannot find a particular code in this topic, see the following ITU-T recommendations or consult your ATM network provider.
  • Q.850, Usage of Cause and Location in DSS 1 and the SS 7 User Part
  • Q.2610, Broadband Integrated Services Digital Network (B-ISDN) Usage of Cause and Location in B-ISDN User Part and DSS 2

VTAM® hint: A possible cause of many errors indicated by ATM network-generated cause and diagnostic codes is an incorrectly coded DLCADDR operand on a GROUP definition statement in the XCA major node or on the PATH definition statement in the switched major node. See z/OS Communications Server: SNA Resource Definition Reference for information about how to code the DLCADDR operand on the GROUP definition statement in the XCA major node and for information about how to code the DLCADDR operand on the PATH definition statement in the switched major node.
