VAX Site Controller Computer

LBI-39128

APPLICATION NOTES

Make sure that the Site Controller computer, at the location where this PMU is to be installed, is a VAX model or a PDP model that has been upgraded to a VAX model. To determine if a PDP model has been upgraded internally to a VAX model, you must look inside the PDP system chassis and see which cards are installed. PDP models that have been upgraded to a VAX model will have their cards arranged in the card cage as shown in Figure 2.

APPLICATION SOFTWARE PROMS

The Site Controller computer’s Application Software PROMs must be marked 344A3265Gx, where x = 6 or higher. (Application Software PROMs with x = 5 or lower will not work for the new PMU.) If new Application Software PROMs are needed, they should be ordered when ordering the new PMU.

PERSONALITY PROMS

The Site Controller computer’s Personality PROMs must be replaced, even if the system currently has an old PMU and a System Manager. New Personality PROMs should be ordered when ordering the new PMU.

When ordering new Personality PROMs, you must give the correct information for the following four PMU parameters (don’t assume that the person taking the order will know what you want, need, or the recommendations given here):

∙PMU Enable - This parameter set (mask) defines (for each channel) if that channel number is to be monitored by the PMU. This parameter is not System Manager re-configurable and therefore all equipped channels must be enabled. It is recommended that all 20 channels be enabled (equipped or not).

∙Power Monitor Unit - This parameter can be set to “Off” (if you want the PMU option disabled) or “On” (if you want the PMU option enabled). This parameter is System Manager re-configurable, but must be set to “On” if the site is being operated without a System Manager. It is recommended that this parameter be set to “On”, even if the site is being operated with a System Manager.

∙PMU Model - This parameter can be set to “Old- 8843” (PMU protocol set to 2400 Baud for Decibel Products DB8843 based old PMU) or “New-8860” (PMU protocol set to 9600 Baud for Decibel Products DB8860 based new PMU). This parameter is not System Manager re-configurable and therefore must be set to “New-8860”.

∙PMU Power Levels - This parameter defines the lower power level limit for all transmitters (one limit is applied to all). This parameter is System Manager re-configurable, but must be set to some power level lower than rated power if the site is being operated without a System Manager. It is recommended that this parameter be set to 50% of the rated power, even if the site is being operated with a System Manager.

NOTE

If this PMU option is being installed in the field, these Personality PROMs must be changed, even if the system currently has the old PMU option and a System Manager.

LBI-39128 specifications

Ericsson LBI-39128 is a comprehensive communication solution designed to meet the ever-evolving demands of modern telecommunications. It is renowned for its ability to enhance network performance while providing a robust framework for various communication technologies. This product primarily targets service providers, enabling them to maximize their operational efficiency and improve service delivery.

One of the key features of the LBI-39128 is its versatility in supporting multiple generation technologies, including 2G, 3G, LTE, and even 5G. This ensures that service providers can seamlessly integrate their existing infrastructure and gradually evolve towards more advanced network capabilities without the need for a complete overhaul. The product caters to a wide array of deployment scenarios, from urban environments with high user density to rural areas requiring expansive coverage.

In terms of network performance, the LBI-39128 excels with its advanced radio technologies. It employs Massive MIMO (Multiple Input Multiple Output) and beamforming techniques, which significantly enhance spectral efficiency and improve user experience. With multiple antennas transmitting and receiving signals simultaneously, users benefit from increased throughput and reduced latency, essential for applications such as video streaming and real-time communications.

Another critical characteristic of the Ericsson LBI-39128 is its focus on energy efficiency. The product integrates intelligent power management systems that optimize energy consumption, thereby reducing operational costs for service providers. This aligns with the growing emphasis on sustainable practices within the telecommunications industry.

Moreover, the LBI-39128 features advanced management and automation capabilities. Its network function virtualization (NFV) support enables operators to deploy virtualized network functions efficiently, allowing for dynamic scaling and resource allocation based on real-time demand. This agility is crucial for handling varying loads and enhancing the overall resilience of the network.

Security is also a primary consideration in the design of the LBI-39128. It incorporates robust encryption methods and secure access protocols to protect sensitive data and ensure the integrity of communication channels. This is particularly important in an age where cyber threats are becoming increasingly prevalent.

In summary, the Ericsson LBI-39128 is a state-of-the-art telecommunications solution that stands out due to its support for multiple technologies, advanced radio capabilities, energy efficiency, automated management, and robust security features. Its design reflects the needs of contemporary service providers, allowing them to build and sustain high-performance networks that meet the demands of future communications.
