Procedure

The following steps involve equipment in the Site Controller cabinet, except as noted:

1.Turn off the main 12V power supply for the cabinet.

2.Replace the 5 1/4 inch blank panel just above the Downlink GETC (called Trunking Card in some older installations) with the PMU. There will be a half rack unit space (7/8 inch) both above and below the PMU.

3.Connect the #18 red wire from the terminal on the back of the PMU labeled “+”, to TB10-7 on the back of the Downlink GETC shelf.

4.Connect the #18 black wire from the terminal on the back of the PMU labeled “–”, to TB10-6 on the back of the Downlink GETC shelf.

5.Mount the new 19C852632G1 Power Sensor interface module on the left-hand end of the upper EDACS Interface Panel in the upper rear of the cabinet, using

the four thread forming screws provided with it. (You will need a T15 Torx-head screwdriver.) If an old Power Sensor interface module is mounted there, replace it with the new 19C852632G1 interface module.

This interface module contains two 19C852379G1 Channel Termination Boards, each containing 12 shorting jumpers. The board plugged into J1 is used to short any unused power sensor circuit for Transmitter channels #1 through #12. The board plugged into J2 is used to short any unused power sensor circuit for Transmitter channels #11 through #20.

6.Remove the 19C852379G1 Channel Termination Board from J1 on the Power Sensor interface module (installed in step 5), and connect a 25-pair cabinet interconnect cable in its place. Connect the other end of the 25-pair cabinet interconnect cable to J14 or J15 on the Power Sensor interface module in the EDACS Repeater cabinet containing the transmitter for channel #1). If the two cabinets are next to each other in the same row, use a 5-ft 19D903880P120 cable. If the two cabinets are across from each other in different rows, use a 15-ft 19D903880P121 cable.

7.Starting with the cabinet containing the transmitter for channel #1, follow the daisy chain of 25-pair cabinet interconnect cables connected to J14 and J15 on the Power Sensor interface module in each EDACS Repeater cabinet until an empty J14 or J15 connector is found. Plug the 19C852379G1 Channel Termination Board (removed in the previous step) into this empty connector.

8.Remove the shorting jumper for each transmitter channel # equipped with a power sensor (P# corresponds to transmitter channel #).

Note that there is a shorting jumper for transmitter channels #11 and #12 on each of the 19C852379G1 Channel Termination Boards. Therefore, if transmitter channel #11 or #12 is equipped with a power sensor, a jumper must be removed from each of the two channel termination boards.

9.If the system does not have any additional EDACS Repeater cabinets not included in the daisy chain in the previous step, go to step 11.

If the system has additional EDACS Repeater cabinets not included in the daisy chain in the previous step, remove the 19C852379G1 Channel Termination Board from J2 on the Power Sensor interface module (installed in step 5), and connect a 25-pair cabinet interconnect cable in its place. Connect the other end of the 25-pair cabinet interconnect cable to J14 or J15 on the Power

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.
