SCCP:Error Performance Report

The performance report error (event) notification message is received by the host application when a SCCP is reporting a performance error.

General explanation of the error event notification fields in the performance report:

• The SCCP handle field specifies the handle of the SCCP instance.

---

• The Cause field specifies the cause of the error performance report.

SCCP event and cause LSAP alarm under CATEGORY_PROTOCOL

Cause	Report parameters used	Description
Unknown	None	Unknown
No Translation - bad address (RTF_NTBADADDR)	un32NetworkId ProtocolVariant Called Address Calling Address	Routing failure - No translation for address of such nature
No translation - specific address (RTF_NTSPECADDR)	un32NetworkId Protocol Variant Called Address Calling Address	Routing failure - No translation for this specific address
Network failure (RTF_NETWORK_FAIL)	un32NetworkId ProtocolVariant Calling Address	Routing failure - Network failure (point code not available)
Network congestion (RTF_NETWORK_CONGESTION)	un32NetworkId ProtocolVariant DPC Calling Address	Routing failure - Network congestion
Subsystem failure (RTF_SUBSYSTEM_FAILURE)	un32NetworkId ProtocolVariant	Routing failure - Subsystem failure (unavailable)
System congestion (RTF_SUBSYSTEM_CONGESTION)	un32NetworkId ProtocolVariant Calling Address	Routing failure - Subsystem congestion
Routing failure - unequipped user (RTF_UNEQUIPPED)	un32NetworkId ProtocolVariant	Routing failure - Unequipped user (subsystem).
Reassembly outside of sequence (REASSEMBLY_OUTSEQ)	un32NetworkId ProtocolVariant Calling Address un32CongestionLvl	Reassembly error - Segment received out of sequence
Hop violation (HOP_VIOLATION)	un32NetworkId ProtocolVariant Called Address Calling Address	Hop counter violation (XUDT(S) / LUDT(S))
Segment failure - too large (SEGFAIL_TOO_LARGE)	un32NetworkId ProtocolVariant	Message too large for segmentation
Subsystem congested received (SSC_RECV)	un32NetworkId ProtocolVariant DPC un32CongestionLvl	SCCP / Subsystem congested message received.
Subsystem prohibited received (SSP_RECV)	un32NetworkId ProtocolVariant DPC un32SSN	Subsystem prohibited message received

Description of parameters

General explanation of the Report-specific information parameters:

• The Network identifier parameter specifies the ID of the network
• The Called address parameter specifies the called party address. See the Entity explanation in GTT Address Map Configuration
• The Calling address parameter specifies the calling party address. See the Entity explanation in GTT Address Map Configuration
• The Destination point code parameter (DPC) specifies the point code of the node where the route is terminating
• The Protocol variant parameter specifies the SCCP protocol variant. See the SCCP protocol variant table in Toolpack:Create a SCCP network
• The Subsystem number parameter specifies a subsystem number. See the SCCP SSN value to identify SCCP user table in Toolpack:Create a SCCP route.
• The Segmentation reference parameter specifies the SCCP segmentation local reference number
• The Congestion level parameter specifies the remote SCCP congestion level (reception of SSC). Value is in range 0 to 7.
