Cisco Media Gateway Controller Release 9 Regulatory Compliance and Safety Information

Translated Safety Warnings

Attention Un faible pourcentage de blocs d'alimentation secteur pour le Catalyst 5500 ont subi un défaut de conception. Ces blocs d'alimentation ont été vendus en option ou montés en série sur les châssis commandés entre décembre 1996 et décembre 1997. Lorsqu'ils sont manipulés sans précautions, ils peuvent provoquer un choc électrique de faible intensité. Toutefois, le risque associé au défaut de conception est mineur. La conception actuelle ne représente aucun danger lorsque le bloc d'alimentation est manipulé correctement. Pour extraire le bloc d'alimentation secteur en toute sécurité, suivez les instructions ci-dessous.

Assisté des services techniques de Cisco, le constructeur du bloc d'alimentation a modifié la conception du matériel. En outre, Cisco offre d'échanger tout bloc d'alimentation secteur sur simple demande et sans aucun frais. Pour obtenir un remplacement de ce matériel, contactez le service clientèle Cisco en téléphonant au 1-800-553-NETS (6387) ou au 1-408-526-7208, ou en envoyant un courrier électronique à cs-rep@cisco.com. Pour plus de détails, contactez le centre d'assistance technique par téléphone au 1-800-553-24HR (2447) ou par courrier électronique à l'adresse tac@cisco.com.

Warnung Ein geringer Prozentsatz der zwischen Dezember 1996 und Dezember 1997 als Ersatzteile oder zusammen mit einer Chassis verschickten Wechselstromanschlüsse des Catalyst 5500 sind von einem Konstruktionsfehler betroffen. Wenn Sie diese Stromanschlüsse nicht mit gebotener Vorsicht behandeln, besteht die Gefahr eines leichten elektrischen Schlags. Wir glauben nicht, daß es sich hierbei um ein gravierendes Problem handelt. Wir sind der Auffassung, daß die gegenwärtige Konstruktion des Stromanschlusses bei korrekter Handhabung kein Sicherheitsrisiko darstellt. Um die Wechselstrom-Eingangsstomzufuhr sicher zu entfernen, verfahren Sie wie folgt.

Um das Problem zu beheben, hat der Hersteller der Stromanschlüsse mit technischer Hilfe von Cisco eine Konstruktionsänderung vorgenommen. Auf Anfrage werden wir außerdem jedem Kunden kostenlos Ersatz für die Wechselstrom-Eingangsstromanschlüsse bieten. Um einen solchen Austausch zu arrangieren, kontaktieren Sie bitte Cisco Systems Customer Service unter 800

553-NETS (6387), 408 526-7208, oder e-mail cs-rep@cisco.com. Sollten Sie weitere technische Hilfe benötigen, wenden Sie sich bitte an das Technical Assistance Center (TAC) unter 800 553-24HR (2447) oder e-mail tac@cisco.com.

Avvertenza Un problema di progettazione potrebbe influire una piccola percentuale degli alimentatori elettrici AC-input del Catalyst 5500 inviati come pezzi di ricambi e degli alimentatori AC-input inviati con le ordinazioni di chassis tra dicembre 1996 e dicembre 1997. Se non maneggiate questi alimentatori elettrici con cautela, rincorrerete il rischio di scosse elettriche. Crediamo che i rischi rincorsi con questo problema di progettazione non siano significanti, e, che l’alimentatore elettrico sia sicuro se viene maneggiato correttamente. Utilizzate la procedura seguente per rimuovere l’alimentatore AC-input con le dovute precauzioni.

Il fabbricante dell’alimentatore elettrico, con l’assistenza tecnica di Cisco Systems, ha eseguito cambiamenti sulla progettazione per rettificare il problema. In oltre, sostituiremo gratuitamente l’alimentatore elettrico AC-input a tutti i clienti che lo richiederanno. Per ottenere un nuovo alimentatore contattate il servizio clienti di Cisco Systems a 800 553-NETS(6387), 408 526-7208, oppure inviate una E-mail a cs-rep@cisco.com. Se desiderate maggiore assistenza tecnica, contattate TAC Technical Assistance Center a 800 552 24HR(2447) oppure inviate una E-mail a tac@cisco.com.

Gateway Controllers specifications

Cisco Systems Gateway Controllers play a pivotal role in the modern networking landscape, particularly within service provider infrastructures. These devices serve as critical components that facilitate the efficient management of voice, video, and data traffic, enabling seamless communication across diverse networks. Combining robustness, scalability, and advanced features, Cisco's Gateway Controllers provide businesses with the tools necessary to optimize their network environments.

One of the standout features of Cisco Gateway Controllers is their ability to handle various signaling protocols, including SIP (Session Initiation Protocol), H.323, and MGCP (Media Gateway Control Protocol). This flexibility ensures interoperability with a wide range of telecom systems and devices, which is crucial for organizations transitioning to IP-based communications.

Integration of voice and video services is made seamless through advanced transcoding capabilities. Cisco Gateway Controllers can convert media streams between different codecs, ensuring high-quality communication regardless of the endpoint's capabilities. This is particularly valuable for enterprises with a mix of legacy and modern communications equipment, as it protects existing investments while facilitating growth.

Traffic management is another significant characteristic of Cisco Gateway Controllers. They utilize sophisticated traffic engineering techniques to prioritize real-time communication signals and optimize bandwidth allocation. Quality of Service (QoS) mechanisms ensure that voice and video traffic is given priority over data traffic, reducing latency and maintaining call quality even during peak usage.

Security features are also a hallmark of Cisco's solutions. Gateway Controllers include robust encryption, access control, and intrusion prevention systems to ensure that network communications are protected against potential threats. This is increasingly important as organizations face a growing number of cybersecurity challenges.

Additionally, Cisco's extensive software ecosystem, including platforms like Cisco Unified Communications Manager, allows for an integrated approach to communication solutions. This interconnectivity not only simplifies management but also enhances the capabilities of Cisco's Gateway Controllers by enabling advanced features like unified messaging and presence information.

Overall, Cisco Systems Gateway Controllers combine advanced technologies, essential features, and security measures to support modern networking needs. Their ability to handle diverse communication protocols, coupled with traffic management and high-level integration, positions them as a crucial solution for organizations seeking to leverage the full potential of converged communication systems. By incorporating these services, businesses can enhance operational efficiency and improve overall user experience, paving the way for future technological advancements in communication.
