This cause is supported on a network http://www.cisco.com/c/en/us/support/docs/dial-access/integrated-services-digital-networks-isdn-channel-associated-signaling-cas/8607-isdn-disc-code.html dependent basis.

Fehlermeldung direkt von der ISDN-Software --------------------------------------------- 0 Die gewaehlte ISDN-Rufnummer wurde nicht erreicht, die Verbindung wurde nach Ueberschreitung eines Zeitlimits ausgeloest. Eine http://www.lf69.at/netzwerktechnik/FAQs/faq09.htm moegliche Ursache hierfuer ist eine unvollstaendige Rufnummer (fehlende Amtsziffer beim Waehlen aus Nebenstellenanlagen, fehlende EAZ beim Anwaehlen von anderen Teilnehmern ...) 0x01 "No channel available" Es ist kein ISDN-B-Kanal mehr frei um weitere Verbindungen herzustellen. Wieviele Kanaele momentan verwendet/belegt sind, laesst sich durch Aufruf von "isistat -i" kontrollieren (NB=Number of B-Channels, UB=Used cause code B-Channels) 0x02 "Illegal protocol options" Diese Meldung resultiert aus fehlerhaften Eintraegen in der Datei "/usr/isi/config/services" oder in der Datei "/usr/isi/config/protocols" 0x03 "Illegal ISDN address" Diese Meldung resultiert aus feherhaften Eintraegen in der Datei "/usr/isi/config/hosts" oder in der Datei "/usr/isi/config/services". Die ISDN-Rufnummer (Aufbau siehe Handbuch ISI/Base, Seite 4-23) darf nur numerische Zeichen enthalten. SI, isdn cause codes AI und ggf. EAZ werden aus der Datei services ermittelt. Die DAD stammt aus der Datei hosts. 0x08 "Cannot activate L1" Der Layer 1 einer ISDN-Verbindung kann nicht aufgebaut werden. Dies bedeutet in der Regel eine physikalische Unterbrechung zwischen Rechner und Anschluss- dose, oder einen absolut inaktiven ISDN-Anschluss. Kontrollmoeglichkeiten zum Eingrenzen der Ursache koennen sein : - Anschluss eines anderen ISDN-Endgeraetes (z.B. Telefon) an die Dose und Test. - Anwahl der Nummer von einem anderen Apparat (Kein Anschluss unter dieser Nr ?). - direkter Anschluss des Geraetes an das Network Terminal (NT) der Bundespost. Dadurch koennen z.B. Fehler in der Inhouse-Verdrahtung erkannt werden. 0x09 "Cannot get TEI" Der Versuch eine TEI (Terminal Endpunkt Identifier) am S0-Bus zu erhalten, ist gescheitert. Eventuell haben zum selben Zeitpunkt andere Endgeraete am S0-Bus ebenfalls versucht eine TEI zu erhalten. 0x0a "Protocol violation on L2" 0x39 "Internal protocol error" 2.
