ISDN Cause Codes

This section explains how to interpret the Integrated Services Digital Network (ISDN) disconnect cause code to identify the reason a call was disconnected.

Table B-7 provides a breakdown of the ISDN Q931 disconnect cause code.

Table B-7 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 where in the circuit path the disconnected cause code was generated. In the example above, 0x82 indicates the call was disconnected from the local telco switch.

This list will help you interpret 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 the 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-7). Table B-8 shows the cause value field and description.

The last two hexadecimal digits (08 in Table B-7) are optional and are not commonly used for diagnostic purposes. Use the table below to associate a disconnect cause code and the reason for the disconnect.

Table B-8 Q931 Disconnect Cause Codes 

Code
Cause Description
Additional Information

81

Unallocated or unassigned number

The ISDN number is sent to the switch in the correct format. However, the number is not assigned to destination equipment.

82

No route to specified network

The ISDN exchange is asked to route the call through an unrecognized intermediate network.

83

No route to destination

The call routes through an intermediate network that does not serve the destination address.

86

Channel unacceptable

The service quality of the specified channel is insufficient to accept the connection.

87

Call awarded and delivered in established channel

The user assigns an incoming call that is connecting to an already established call channel.

Code
Cause Description
Additional Information

90

Normal call clearing

Normal call clearing occurs. No action is required

91

User busy

Called system acknowledges the connection request, but cannot accept the call because all B-channels are in use.

92

No user responding

Destination does not respond to the call.

93

No answer from user

Destination responds to the connection request, but fails to complete the connection within the prescribed time. The problem is at the remote end of the connection.

95

Call rejected

Destination can accept call, but rejects it for an unknown reason.

96

Number changed

ISDN number used to set up the call is not assigned to a system.

9A

Non-selected user clearing

Destination can accept the call, but rejects it because it is not assigned to the user.

9B

Destination out of order

Destination cannot be reached because of an interface malfunction, and a signaling message cannot be delivered. This can be a temporary condition, but it could last for an extended period. (The remote equipment might be turned off.)

9C

Invalid number format

Connection fails because destination address is presented in an unrecognizable format, or destination address is incomplete.

9D

Facility rejected

Facility requested by user cannot be provided by the network.

9E

Response to STATUS ENQUIRY

Status message is generated in direct response to receiving a status inquiry message.

9F

Normal, unspecified

Reports the occurrence of a normal event when no standard cause applies. No action required.

A2

No channel available

Connection fails because no appropriate channel is available to take the call.

A6

Network out of order

Destination cannot be reached because of network malfunction, and the condition can last for an extended period. An immediate reconnect attempt will probably fail.

A9

Temporary failure

Error occurs because of a network malfunction. The problem is resolved shortly.

AA

Switching equipment congestion

Destination cannot be reached because the network switching equipment is temporarily overloaded.

AB

Access information discarded

Network cannot provide the requested access information.

AC

Requested channel not available

Remote equipment cannot provide the requested channel for an unknown reason. This can be a temporary problem.

AF

Resources unavailable, unspecified

Requested channel or service is unavailable for an unknown reason. This can be a temporary problem.

B1

Quality of service unavailable

Requested quality of service cannot be provided by the network. This can be a subscription problem.

B2

Requested facility not subscribed

Remote equipment supports requested supplementary service by subscription only.

B9

Bearer capability not authorized

User requests a bearer capability the network provides, but user is not authorized to use it. This can be a subscription problem.

Code
Cause Description
Additional Information

BA

Bearer capability not presently available

Network normally provides the requested bearer capability, but it is unavailable at the present time. This can be a temporary network problem or a subscription problem.

BF

Service/option not available, unspecified

Network or remote equipment cannot provide the requested service option for an unspecified reason. This can be a subscription problem.

C1

Bearer capability not implemented

Network cannot provide bearer capability requested by the user.

C2

Channel type not implemented

Network or destination equipment does not support requested channel type.

C5

Requested facility not implemented

Remote equipment does not support requested supplementary service.

C6

Only restricted digital info bearer capability available

Network cannot provide unrestricted digital information bearer capability.

CF

D1

Invalid call reference value

Remote equipment receives a call with a call reference that is not currently in use on the user-network interface.

D2

Channel does not exist

Receiving equipment is requested to use a channel that is not activated on the interface for calls.

D3

Suspended call exists, but call id does not

Network receives a call resume request that contains a Call Identify that indicates it is being used for a suspended call.

D4

Call id in use

Network receives a call resume request that contains a Call Identity that indicates the resume request is in use for a suspended call.

D5

No call suspended

Network receives a call resume request when there is not a suspended call pending. This can be a transient error that will be resolved by successive call retries.

D6

Call with requested call id has been cleared

Network receives a call resume request that contains a Call Identity that once indicated a suspended call. However, the suspended call was cleared either by time-out or by remote user.

D8

Incompatible destination

Indicates that an attempt is made to connect to non-ISDN equipment. (For example, an analog line.)

DB

Invalid transit network selection

ISDN exchange is asked to route the call through an unrecognized intermediate network.

DF

Invalid message, unspecified

An invalid message is received with no standard cause. This is usually due to a D-channel error. If error occurs systematically, report it to your ISDN service provider.

E0

Mandatory IE missing

Receiving equipment receives a message that does not include a mandatory information element. This is due to a D-channel error. Ensure the switch type is configured correctly. A Cisco IOS® Software upgrade on the router can alleviate this issue. If error occurs systematically, report it to your ISDN service provider.

Code
Cause Description
Additional Information

E1

Message type not implemented

Receiving equipment receives an unrecognized message, because the message type is invalid or the message type is valid, but not supported. The cause is a problem with the remote configuration or with the local D-channel.

E2

Message not compatible with call state or not implemented

Remote equipment receives an invalid message with no standard cause. The cause is a D-channel error. If the error occurs systematically, report it to ISDN service provider.

E3

IE not implemented

Remote equipment receives a message that includes unrecognized information elements. This is a D-channel error. If the error occurs systematically, report it to your ISDN service provider.

E4

Invalid IE contents

Remote equipment receives a message that includes invalid information elements. This is due to a D-channel error.

E5

Message not compatible with call state

Remote equipment receives an expected message that does not correspond to the current state of the connection. This is a D-channel error.

EF

Protocol error, unspecified

An unspecified D-channel error with no other standard cause.

FF

Interworking, unspecified

An event occurs, but the network does not provide causes for the action it takes. The precise problem is unknown.

??

Unknown Cause value

The cause value is unknown.

Transmitted Q.761 Cause Code Mappings

Table B-16 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 Q761

7- Belgian Mobistar

8- Korean Q761

9- ETS_300_356 and NTT
