The correct answer is 155.520, 622.080, and 2488.320 Mb/s.

The correct answer is 155.520 Mb/s. This refers to the transmission speed of the STM-1, which is a standard for synchronous digital hierarchy (SDH) telecommunications. The "Mb/s" stands for megabits per second, indicating a data transfer rate of 155.520 million bits per second.

The correct answer is RSOH y MSOH. The section header of an STM-1 is composed of RSOH (Regenerator Section Overhead) and MSOH (Multiplex Section Overhead). These headers contain important information and control bits that are used for monitoring and managing the transmission of data over the STM-1 network. The RSOH includes information about the regenerator section, while the MSOH contains information about the multiplex section. Both headers are essential for maintaining the integrity and quality of the STM-1 signal.

The correct answer is "Jerarquía Digital Plesiócrona". The term PDH stands for "Plesiochronous Digital Hierarchy", which refers to a digital transmission technology used in telecommunications networks. Plesiochronous means that the timing of the signals is slightly different, but still within an acceptable range. The PDH system is used to multiplex and transmit multiple voice and data channels over a single physical link, allowing for efficient and cost-effective communication.

The correct answer is NPI. NPI stands for "Null Pointer Indication," which is a term used in computer programming to refer to the indication of a null pointer. A null pointer is a pointer that does not point to any memory location. In programming, it is important to handle null pointers properly to avoid errors and crashes. Therefore, NPI is the correct abbreviation for indicating a null pointer.

The correct answer is 9953,280 Mb/s. This is the correct transmission speed for an SDH STM-64. SDH stands for Synchronous Digital Hierarchy, and STM-64 is a specific level within this hierarchy. It has a transmission capacity of 9953,280 Megabits per second (Mb/s).

The correct answer is "Contenedor". A "contenedor" is a container or holder where the input information signals are arranged according to the SDH (Synchronous Digital Hierarchy) structure. It is used to organize and transport the data signals efficiently within the SDH network.

The correct answer is 2488.320 Mb/s. This is the correct answer because it matches the given statement that it is the transmission speed of the STM-16. The other options, 24883.20 Kb/s, 2488.320 Kb/s, and 2488320 Mb/s, do not match the given statement and are therefore incorrect.

The correct answer is 622.080 Mb/s. This is because the question is asking for the transmission speed of the STM-4, which is a specific type of digital transmission system used in telecommunications. The unit of measurement for data transmission speed is typically expressed in bits per second (bps), and in this case, it is given in megabits per second (Mb/s). Therefore, the correct answer is 622.080 Mb/s.

Cuando un elemento de Red SDH pierde su sincronización y utiliza un reloj interno, está en modo "De Libre Carrera". Esto significa que el elemento está funcionando de manera independiente y no está sincronizado con ningún otro elemento de la red. En este modo, el elemento utiliza su propio reloj interno para mantener su sincronización y operar de manera autónoma.

When the frame rate of the VC-4 is lower than that of the AUG, a positive justification is required. This means that there needs to be a valid reason or explanation for why the frame rate of the VC-4 is slower compared to the AUG. This could be due to factors such as technical limitations, network congestion, or intentional throttling of the frame rate.

The correct answer is HLP because "HLP" represents the highest order trajectory from start to finish. "LLP" represents a lower order trajectory, "RSOH" represents a moderately high order trajectory, and "MSOH" represents a moderately low order trajectory. Therefore, "HLP" is the correct answer as it represents the highest order trajectory.

El sistema SDH permite insertar y extraer canales sin tener que demultiplexar toda la señal. Esto significa que es posible agregar o quitar canales individuales sin tener que descomponer la señal en sus componentes más pequeños. Esta característica es importante porque permite una mayor flexibilidad y eficiencia en el manejo de la señal, ya que no es necesario realizar una demultiplexación completa para realizar cambios en los canales.

The given answer, "MS-FERF," is the correct answer because it is the first alarm mentioned in the list. The other alarms listed, "HP-FERF," "LP-FERF," and "P-FEBE," are not the correct answer because they are mentioned after "MS-FERF" in the list.

The correct answer states that the limits of the high-order path are from high-order assemblers to high-order assemblers. This means that the path is limited to the connection between high-order assemblers and does not extend to other components such as multiplexers or regenerators.

The correct answer is that the east and west sides are connected to their respective adjacent nodes. This means that each side of the synchronous multiplexer is connected to a neighboring node.

The correct answer is SDXC. SDXC stands for Synchronous Digital Cross-Connect, which is a type of digital router used in telecommunications networks. It is known for its ability to route synchronous digital signals efficiently and accurately.

The correct answer is VC-4. In PDH (Plesiochronous Digital Hierarchy) systems, a signal with a rate of 140 Mbits/s can be directly mapped to a VC-4 (Virtual Container-4). VC-4 is a synchronous payload envelope that can carry multiple lower-rate signals, such as VC-3, VC-12, or VC-11. It is commonly used in SDH (Synchronous Digital Hierarchy) networks for multiplexing and transporting different traffic streams.

The correct answer is FERF. This is because FERF stands for Far End Receive Failure, which is an alarm that indicates a failure in receiving signals at the remote end. This alarm is triggered when there is a problem with the transmission or reception of data between two remote locations.

Las letras STM-n significan "Módulo de transporte síncrono de orden n".

K1 y K2 son los Bytes que llevan la información de petición de conmutación y estado actual del enlace.

The correct answer is "Modo Asincrono flotante." This mode is currently used in TELMEX and it includes justification.

The correct answer is 2, 8, 34, 140, and 565 Mbit/s. This is because these are the correct speeds in the PDH hierarchy according to the European standards.

The correct answer is H3. The phrase "byte de oportunidad para la justificación negativa" is in Spanish and translates to "opportunity byte for negative justification." In computer science, a "byte" refers to a unit of digital information. In this context, "byte de oportunidad" suggests that there is a specific byte or piece of information that can be used to justify a negative outcome or decision. Therefore, H3 is the correct answer as it represents the specific byte that holds this opportunity for negative justification.

El apuntador se utiliza para señalar la posición de inicio de los VC's. Esto significa que indica el punto de partida de los Virtual Circuits (VC's) en un sistema de comunicación. El apuntador es esencial para establecer y mantener la conexión entre los dispositivos de origen y destino, ya que permite identificar dónde comienza la transmisión de datos en el VC. Sin el apuntador, no sería posible establecer una comunicación adecuada entre los dispositivos.

A canal de 192 kbps para comunicación de datos es de DCC-R.

The correct answer is G.707, G.708 y G.709. These are the recommendations that define the SDH (Synchronous Digital Hierarchy) standard. SDH is a standardized multiplexing protocol used in telecommunications to transport large amounts of data over optical fiber networks. G.707 defines the basic structure and multiplexing of the SDH signal, G.708 specifies the mapping of PDH (Plesiochronous Digital Hierarchy) signals into SDH, and G.709 defines the framing structure and management of the SDH signal. These recommendations are essential for the implementation and operation of SDH networks.

In this synchronization mode, there are multiple primary reference clocks (PRCs) or primary reference time sources. This means that there are multiple sources of time that can be used as references for synchronization. The term "pseudo" suggests that although there are multiple sources, they may not be truly synchronized or accurate. Therefore, the system may appear to be synchronized, but it is not truly synchronous.

The given answer, C-4, is correct because it matches the pattern of the other options. The pattern appears to be a letter followed by a number, with the number increasing by 1 each time. Therefore, C-4 is the next logical option in the sequence.

The correct answer is "De los multiplexores STM-n a los multiplexores STM-n." This means that the limits of the MUX section are from the STM-n multiplexers to the STM-n multiplexers. This suggests that the MUX section is responsible for multiplexing and demultiplexing signals at the STM-n level, ensuring that the signals are properly transmitted and received within the MUX section.

The correct answer is "Red de administracion de telecomunicaciones TMN". This is because TMN (Telecommunications Management Network) is a system that is used for the operation and maintenance of the SDH (Synchronous Digital Hierarchy) network. TMN provides functions such as network management, fault management, and performance management, allowing for efficient operation and maintenance of the SDH network. The other options mentioned, such as DCC-R, DCC-M, and TELEPAC, are not specifically related to the operation and maintenance of the SDH network.
