Přehled kódů III. část stavových hlášení - dobrá pomůcka při řešení problémů se spojením euroISDN telefonu

pokračování ...

Máte-li problém s např. s euroISDN telefonem, přinášíme Vám přehled kódů stavových hlášení, která se mohou objevovat na displeji přístroje. Tyto kódy nejsou podle našich zkušeností běžně dostupné, jejich znění přinášíme v originále - tedy v angličtině.

57 39 Bearer capability not authorized Note 3 The user requested a bearer capability that the network provides, but the user is not authorized to use it. This might be a subscription problem.
58 3A Bearer capability not presently available Note 3 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.
63 3F Service or option not available, unspecified   The network or remote equipment was unable to provide the requested service option for an unspecified reason. This might be a subscription problem.
65 41 Bearer capability not implemented Note 3 The network cannot provide the bearer capability requested by the user.
66 42 Channel type not implemented Channel Type (Note 6) The network or the destination equipment does not support the requested channel type.
69 45 Requested facility not implemented Facility Identification (Note 1) The remote equipment does not support the requested supplementary service.
70 46 Only restricted digital information bearer capability is available   The network is unable to provide unrestricted digital information bearer capability.
79 4F Service or option not implemented, unspecified   The network or remote equipment is unable to provide the requested service option for an unspecified reason. This might be a subscription problem.
81 51 Invalid call reference value   The remote equipment received a call with a call reference that is not currently in use on the user-network interface.
82 52 Identified channel does not exist Channel identity The receiving equipment is requested to use a channel that is not activated on the interface for calls.
83 53 A suspended call exists, but this call identity does not   The network received a call resume request. The call resume request contained a Call Identify information element that indicates that the call identity is being used for a suspended call.
84 54 Call identity in use   The network received a call resume request. The call resume request contained a Call Identify information element that indicates that it is in use for a suspended call.
85 55 No call suspended   The network received a call resume request when there was not a suspended call pending. This might be a transient error that will be resolved by successive call retries.
86 56 Call having the requested call identity has been cleared Clearing cause 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.
88 58 Incompatible destination Incompatible parameter (Note 2) Indicates that an attempt was made to connect to non-ISDN equipment. For example, to an analog line.
91 5B Invalid transit network selection   The ISDN exchange was asked to route the call through an unrecognized intermediate network.
95 5F Invalid message, unspecified   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.
96 60 Mandatory information element is missing Information element identifier(s) (Note 5) 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.
97 61 Message type non-existent or not implemented Message type The receiving equipment received an unrecognized message, either because the message type was invalid or because the message type was valid but not supported. The cause is due to either a problem with the remote configuration or a problem with the local D channel.
98 62 Message not compatible with call state or message type non-existent or not implemented Message type 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.
99 63 Information element non-existent or not implemented Information element identifier(s) (Notes 5, 7) 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.
100 64 Invalid information element contents Information element identifier(s) (Note 5) The remote equipment received a message that includes invalid information in the information element. This is usually due to a D-channel error.
101 65 Message not compatible with call state Message type 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.
102 66 Recovery on timer expires Timer number (Note 8) An error-handling (recovery) procedure was initiated by a timer expiry. This is usually a temporary problem.
111 6F Protocol error, unspecified   An unspecified D-channel error when no other standard cause applies.
127 7F Internetworking, unspecified   An event occurred, but the network does not provide causes for the action that it takes. The precise problem is unknown.

Note 1: The coding of facility identification is network dependent.

Note 2: Incompatible parameter is composed of incompatible information element identifier.

Note 3: The format of the diagnostic field for causes 39, 3A, and 41 is shown in the ITU-T Q.850 specification, Table 3b/Q.850.

Note 4: User-supplied diagnostic field is encoded according to the user specification, subject to the maximum length of the cause information element. The coding of user-supplied diagnostics should be made in such a way that it does not conflict with the coding described in Table B-2.

Note 5: Locking and non-locking shift procedures described in the ITU-T Q.931 specification apply. In principle, information element identifiers are in the same order as the information elements in the received message.

Note 6: The following coding is used:

Note 7: When only locking shift information element is included and no variable length information element identifier follows, it means that the codeset in the locking shift itself is not implemented.

Note 8: The timer number is coded in IA5 characters. The following coding is used in each octet:

Note 9: The diagnostic field contains the entire transit network selection or network-specific facilities information element, as applicable.

Note 10: See Table B-2 for the coding that is used.

Bearer Capatibility Values

Table B-4 lists the ISDN bearer capability values that display in the following format within the debug commands:
