Overview
ISDN errors are reported in the isdnCallHistoryTable. Errors originating from
the ISDN are reported in the DSS1Cause and 1TR6Causefc fields, depending
on which service you’re using (Euro ISDN and National ISDN repectively). Errors originating locally on the BinTec router are reported in the LocalCause
field.

the
Possible Values
Meaning
0x80
Normal call clearing
No error occurred.
0x81
Unallocated (unassigned) number This cause
indicates that the destination, requested by the
calling user cannot be reached because,
although the number is in a valid format, it is
not currently assigned (allocated).
0x82
No route to specified transit network
This cause indicates that the equipment sending this cause has received a request to route
the call through a particular transit network
which it does not recognise. The equipment
sending this cause does not recognise the transit network either, because the transit network
does not exist or because that particular, while
it does exist, does not service the equipment
which is sending this cause.
This cause is supported on a network-dependent basis.
0x83
No route to destination
This cause indicates that the called user can
not be reached because the network through
which the call has been routed does not serve
the destination desired. This cause is supported on a network-dependent basis.
0x86
Channel unacceptable
This cause indicates the channel most recently
identified is not acceptable to the sending entity
for use in this call.

awarded the incoming call, and that the incoming call is being connected to a channel already
established to that similar calls (e.g. packetmode X.25 virtual calls).
0x90
Normal call clearing
This cause indicates that the call is being
cleared because one of the users involved in
the call has requested that the call be cleared.
0x91
User busy
This cause is used when the called user has
indicated the inability to accept another call.
0x92
User not responding
This cause is used when a user does not
respond to a call establishment message with
either an alerting or connect indication within
the prescribed period of time allocated.
0x93
No answer from user (user alerted)
This cause is used when a user has provided
an alerting indication but has not provided a
connect indication within a prescribed period o f
time.
0x95
Call rejected
This cause indicates that the equipment sending this cause does not wish to accept this call,
although it could have accepted the call
because the equipment sending this cause is
neither busy nor incompatible.
0x96

This cause is returned to a calling user when
the called party number indicated by the calling
user is no longer assigned.

the interface to the destination is not functioning correctly. The term not functioning correctly
indicates that signalling message was unable
to be delivered to the remote user; e.g. a physical layer or data link layer failure at the remote
user, user-equipment off-line.
0x9c
Invalid number format
This cause indicates that the called user can
not be reached because the called party number is not in a valid format or is not complete.
0x9d
Facility rejected
This cause is returned when a facility requested
can not be provided by the network.
0x9e
Response to STATUS ENQUIRY
This cause included in the STATUS message
when the reason for generating the STATUS
message was the prior receipt of a STATUS

Invalid message class
14
Possible Values
Meaning
0xd1
Invalid call reference value
This cause indicates that the equipment sending this cause has received a message with a
call reference which is not currently in use on
the user-network interface.
0xd2
Identified channel does not exist
This cause indicates that the equipment sending this cause has received a request to use a
channel not activated on the interface for a call.
For example, if a user has subscribed to those
channels on a primary rate interface numbered
from 1 to 12 and the user equipment or the network attempts to use channels 13 to 30 this
cause is generated.
0xd3
A suspended call exist, but call identity does
not

been attempted with a call identity which differs
from that in use for any presently suspended
call(s).
Software Reference
ISDN Error Codes
A
DSS1 Causes (Euro ISDN)
ISDN Error Codes
Possible Values
Meaning
0xd4
Call identity in use
This cause indicates that the network has
received a call suspend request. The call suspend request contained a call identity (including
the null call identity) which is already in use for
a suspended call within the domain of interfaces over which the call might be resumed.
0xd5
No call suspended
This cause indicates that the network has
received a call resume request. The call
resume request contained a call identity information element which presently does not indicate any suspended call within the domain of
interfaces over which calls may be resumed.
0xd6
Call with the requested call id has been cleared
This cause indicates that the network has
received a call resume request. The call
resume request contained a call identity information element which once indicated a suspended call; however, that suspended call was
cleared while suspended (either by network
timeout or by the remote user).

This cause indicates that the requested service
or option is not available or is rejected.

This cause indicates that the equipment sending this cause has received a message which is
missing an information element which must be
present in the message before that message
can be processed.
0xe1
Message type non-existent or not implemented
This cause indicates that the equipment sending this cause has received a message with a
message type it does not recognise either
because this is a message not defined or
defined but not implemented by the equipment
sending this cause.
0xe2
Message not compatible with call state
This cause indicates that the equipment sending this cause has received a message such
that the procedures do not indicate that this is a

Information element non-existent or not implemented
This cause indicates that the equipment sending this cause has received a message which
includes information elements not recognised
because the information element identifier is
not defined or it is defined but not implemented
by the equipment sending the cause. However,
the information element is not required to be
present in the message in order for the equipment sending the cause to process the message.
0xe4
Invalid information element contents

or more fields in the information element are
coded in such a way which has not been implemented by the equipment sending this cause.
