ISDN Cause Codes
This section explains how to interpret the Integrated Services Digital Network (ISDN) disconnect cause codes to identify the reason a call was disconnected.
Table B-5 provides a breakdown of the ISDN Q931 disconnect cause code.
Table B-5 Q931 Disconnect Cause Code Explanation
Cause i =
|
0x829F08
|
Parsed Hex Digits
|
0x82
|
9F
|
08
|
Description
|
Cause Code origination point
|
Disconnect Cause Code
|
Optional Diagnostic field
|
The leading 0x in the disconnect code indicates the digits that follow are in hexadecimal.
The first two digits after 0x indicate the point in the circuit path where the disconnected cause code was generated. In the example above, 0x82 indicates that the call was disconnected from the local telco switch.
You can use this list to determine where a call was disconnected:
•0x80—From the router
•0x81—From the private network near the local user (possibly a local private branch exchange [PBX]}
•0x82—From the public network near the local user (local telco switch)
•0x83—From the transit network (in the ISDN cloud)
•0x84—From the public network near the remote user (remote telco switch)
•0x85—From the private network near the remote user (possibly a remote PBX)
•0x87—From the international network
•0x8A—From a network beyond the internetworking point
The two hexadecimal digits that follow the cause code digits above are significant in troubleshooting (9F in Table B-5). Table B-6 shows the cause value field and description.
The last two hexadecimal digits (08 in Table B-5) are optional and are not commonly used for diagnostic purposes. Use Table B-6 to associate a disconnect cause code and the reason for the disconnect.
Table B-6 Q931 Disconnect Cause Codes

Transmitted ISDN PRI Cause Code Mappings
Table B-11 shows the mapping performed if a transmitted ISDN PRI cause code is supported by one or more of the protocol variants listed in the columns on the right. If the transmitted ISDN PRI cause code is not supported by a protocol variant, then that variant's column is not checked. If no transmitted ISDN PRI cause code value is mapped to the internal cause code, the ISDN PRI cause code value transmitted is NormalUnspecified (31).

Transmitted Q.761 Cause Code Mappings
Table B-13 shows the mapping performed if a transmitted Q.761 cause code is supported by one or more of the protocol variants listed in the 17 columns on the right. If the transmitted Q.761 cause code is not supported by a protocol variant, then that variant's column is not checked. If there is no transmitted Q.761 cause code value mapped to the internal cause code, the Q.761 cause code value that is transmitted is NormalUnspecified (31). For definitions of the Q.761 cause code values see Q.850, section 2.2.7.
Variants are:
1. Standard Q.761
2. Australian Q.761
3. Finnish Q.761
4. Japanese Q.761
5. Japanese ETS_300_356
6. Hong_Kong Q.761
