The cylinder shape overestimates the compliance distances right beside the antenna. Power can be connected to the base station in two ways: Number of units per cabinet per cabinet: All required transmission ericson and battery backup must be housed outside the cabinet. It is available in an external cabinet. The height of the cylinder is the antenna height plus equal distances above and below the antenna.
The current through a closed 0 W contact is 1. Number of units per cabinet: All the files seems to be written in some high level machine code as I can not interpret it.

A failed unit can easily be replaced by a new one. The compliance boundary is defined as a cylinder around the antenna. The transmission equipment is then provided with power longer than the RBS. For dimensions, see Figure 1 on page 5. The cabinet cover protrudes 77 mm in front of the cabinet. The DXU is also provided with four ports for transmission interfaces.
The external alarms are defined at the installation.
Instead it is located almost at the edge, facing towards the centre of the cylinder. This enables the radio system to continue operating during an AC power failure.
Each distribution circuit in the cabinet is connected to a IDM circuit breaker. The base frame is used as a template to mark new holes.
rvs In reality the occupational compliance distance by the side, in line with the front of the antenna, is less than 0. Space for future expansion must be considered, as indicated by the dotted lines in the figure above.

It improves the receiver sensitivity. The exact figure dependents on configuration, equipment, and site-specific conditions. As the antenna field distributions will differ, complete calculations or measurements may be necessary to establish the compliance boundary for other configurations chosen by the customer.
The resulting dimensions, in metres, for a compliance boundary for both public and occupational exposure are shown in Table 8 on page The cabinet is tested for seismic exposure with a test frequency of 1—35 Hz. The contents of this rbz are subject to revision without notice due to continued progress eriscson methodology, design and manufacturing.

It is the interface between the transceivers and the antenna system. I will go through the different units starting with the battery fuse unit, then the CPU, then the power supply and at last, which also have a long teardown video, the power amplifier.
Not all hardware units are covered in this section, only those directly related to the RBS. The distance between the rear of the antenna and the edge of the cylinder is the Distance behind antenna.

There is not much to tell about the power supply unit. The alarm device connected to the screw terminals should be isolated relay contacts. Sorry, your blog edicsson share posts by email. Vandal Resistance If cover is used, unauthorized access is not possible without damaging the unit.
Overvoltage protection for external alarm cables. In the event of AC power failure, the batteries deliver the necessary power to the radio cabinet as well as to the transmission equipment, if used.
Ericsson RBS with 6 sectors
All the files are without file extensions and on a FAT formatted file system. The acoustic noise dispersion values for a free-standing cabinet and a cabinet installed against a wall were tested according to the ISO standard. The earth grounding screws are located on the top and bottom of the cabinet on the left-hand side. The long green connector has external alarm options from malfunction in the fuse unit.
Deviations from these values can be experienced due to the nature of materials in the environment where the cabinet is installed. Remember me on this computer. The voltage between terminals with an open contact is 24 V DC.
