If there are any Dead Line outcomes not listed here, please refer to the following URL which may be able to help you gain the necessary description:
The network cannot provide the requested access information.
The user requested a bearer capability that the network provides, but the user is not authorised to use it. This might be a subscription problem.
The network normally provides the requested bearer capability, but it is unavailable at the present time. This might be due to a temporary network problem or to a subscription problem.
The network cannot provide the bearer capability requested by the user.
The user is assigned an incoming call that is being connected to an already-established call
The destination is capable of accepting the call but rejected the call for an unknown reason.
The network or the destination equipment does not support the requested channel type.
The service quality of the specified channel is insufficient to accept the connection.
The destination cannot be reached because the interface is not functioning correctly, and a signalling message cannot be delivered. This might be a temporary condition, but it could last for an extended period of time. For example, the remote equipment might be turned off.
The remote equipment does not support the requested supplementary service.
The remote equipment supports the requested supplementary service by subscription only.
The facility requested by the user cannot be provided by the network.
The remote equipment received a message that includes information elements, which were not recognized. This is usually due to a D-channel error. If this error occurs systematically, report it to your ISDN service provider.
The network received a call resume request. The call resume request contained a Call Identity information element, which once indicated a suspended call. However, the suspended call was cleared either by timeout or by the remote user.
An event occurred, but the network does not provide causes for the action that it takes. Problem is unknown.
The remote equipment received a call with a call reference that is not currently in use on the user-network interface.
The remote equipment received a message that includes invalid information in the information element. This is usually due to a D-channel error.
An invalid message was received, and no standard cause applies. This is usually due to a D- channel error. If this error occurs systematically, report it to your ISDN service provider.
The connection could be established because the destination address was presented in an unrecognisable format or because the destination address was incomplete.
The receiving equipment received a message that did not include one of the mandatory information elements. This is usually due to a D-channel error. If this error occurs systematically, report it to your ISDN service provider.
The receiving equipment received an unrecognized message, either
The destination cannot be reached because the network is not functioning correctly, and the condition might last for an extended period of time. An immediate reconnect attempt will probably be unsuccessful.
An error occurred because the network is not functioning correctly. The problem will be resolved shortly.
The connection cannot be established because no appropriate channel is available to take the call.
The call was routed through an intermediate network that does not serve the destination address.
The ISDN exchange is asked to route the call through an unrecognised intermediate network.
The connection cannot be completed because the destination doesn’t not respond to the call.
The ISDN number used to set up the call is not assigned to any system.
An unspecified D-channel error when no other standard cause applies.
An error-handling (recovery) procedure was initiated by a timer expiry. This is usually a temporary problem.
The status message was generated in direct response to the prior receipt of a status enquiry message.
The remote equipment cannot provide the requested channel for an unknown reason. This might be a temporary problem.
The destination cannot be reached because the network switching equipment is temporarily overloaded.
The ISDN number was sent to the switch in the correct format; however, the number is not assigned to any destination equipment.
The called system acknowledges the connection request but is unable to accept the call because all B channels are in use.
The remote equipment received an unexpected message that does not correspond to the current state of the connection. This is usually due to a D-channel error.
The remote equipment received an invalid message, and no standard cause applies. This cause is due to a D-channel error. If this error occurs systematically, report it to your ISDN service provider.
