(1) Normal operation describes the environmental conditions where all units function as specified. (2) Non-destructive conditions describe environmental stress above the l imits for normal conditions with no function guaranteed and unspecified degradation. When the environmental stress has dropped to normal conditions, restoring full RBS performance requires no manual intervention on site. Non-destructive conditions refer to a maximum period of 96 consecutive hours, and a maximum total of 5.5 days in a three-year period.
Ground Vibration s
The RBS 2207 is tested to withstand random vibrations of up to 0.2 m²/s². It is also tested for single shocks up to 40 m/s². The cabinet is tested for seismic exposure with a test frequency of 1 - 35 Hz. Maximum test level of the Required Response Spectrum (RRS) is 50 m/s² within 2 - 5 Hz. The shape of RRS is defined by the ETSI standard.
Levelling
For cabinet levelling purposes, the floor must be level to within ±3 mm/2000 mm and the floor gr adient be within ±0.1
.
4.2 Environment al Imp act
This section describes the effect that the cabinet has on the environment.
Heat Dissipation
The RBS 2207 generates an average heat load of 1000 W. The exact figure is dependent upon confguration, equipment an d site-specific conditions.
4.3 Compliance Distances for Electromagnetic Exposure
The compliance distance is the minimum separation that should be kept between an antenna and a person in order to ensure that ICNIRP RF exposure limits are no t exceeded.

Note: ICNIRP, ‘‘Guidelines for limiting exposure to time-varying electric,
magnetic, and electromagnetic fields (up to 300GHz)’’, International Commission on Non-Ionizing Radiation Pro tection, Health Physics, vol. 74, no. 4, 1998.
Ericsson has performed a free-space near-field RF exposure assessment of typical configurations of RBS 2207 with a re commended antenna. The resulting dimensions, in meter, for a compli ance boundary for both public and occupational exposure are shown in Table 4.
The compliance boundary is defined as a cylinder around the antenna, see figure below. The antenna is not located at the centre of the cylinder. Instead it is located almost at the edge, facing towards the center of the cylinder. The distance between the antenna’s rear and the edge of the cylinder is the "Distance behind antenna". The height of the cylinder is the a ntenna height plus equal distances above and below the antenna. The cylinder shape overestimates the compliance distances right beside the antenna.

7.4 Battery Back-up
Battery back-up can be used to power the site during mains failure and to protect the site from interruptions in the AC mains supply. It is available in an external cabinet.
In the event of mains failure, the batteries in the BBS 2000 or BBS 2202 deliver the necessary power to the radio cabinet as well as to the transmission equipment, if used. This enables the radio system to continue operating during mains failure. The transmission equipment is provided with p ower supply longer than the RBS.
Battery back-up can be delivered for at least 1, 2, 4, 6 or 8 hours back-up time, depending on the chosen configuration of the RBS. The BBS can feed +24 V DC or -48 V DC to transmis sion equipment. Th e -48 V DC supply requires an internal DC/DC converter in the BBS. It is possible to share battery back-up between an RBS 2202 or 2206 and an RBS 2207.

8 Transmission
The RBS 2207 is normally c onnected to a Distribution Frame (DF) that serves as an interface for the transmission (PCM) lines. Two PCM cables are connected to the ports on the connection field of the RBS. The RBS 2207 supports two transmission standards:
T1 1.5 Mbit/s, 100
balanced PCM line
E1 2 Mbit/s, 75
unbalanced (Transmission Adapter used), or 120
balanced line
Link access procedures on C-chann el (LAPD) concentration and LAPD multiplexing can be used to make the transmission resource more efficient.
PCM Overvoltage Module
This module is mounted in the DF and co ntains overvoltage protection for the PCM lines. If the PCM lines are terminated in equipment outside the RBS equipment room, these lines must then be protected by overvoltage protectors (OVP) in the DF. Failure to do so might damage the DXU-21, if a voltage transient is transported along the cable. The RBS 2207 is designed for 100/120
balanced (twisted pair) cable. When a 75 unbalan ced (coaxial) cable is to
be conne cted, the module contains a balun ca rd that converts 75
unbalanced
to 100/120
balanced line.
Optional Transmission Equipment
The cabinet can be connected to optional transmission equipment that is mounted externally. The optional transmission equipment used is:
Transmission adapter t o connect 75
unbalanced line directly to the RBS

Figure 1 RBS 2000 in the Ericsson GSM System
The Base Station System (BSS) contains two functional entities; the Base Station Controller (BSC) and the Base Transceiver Station (BTS).
The BSC handles radio-related functions, such as handover, management of the radio network resources, and cell configuration data. It also controls radio frequency power levels in RBSs and MSs.
The BTS is a network component which serves one cell and is controlled by the BSC. The BTS contains a number of transceivers. It consists of the radio transceivers and all the digital signal processing equipment. RBS 2000 contains equipment for 1 – 3 BTSs.

TMA
The Tower Mounted Amplifier (TMA) compensates for signal loss in the receiver antenna cables, reduces system noise and improves uplink sensitivity. The TMA can consist of a duplex filter. D uplex is the function that allows communication in two directions (sending and receiving) on one channel.
The TMA used for dTRU based products is dual duplex TMA (ddTMA).
Some configurations can use a TMA designed for reception only (rTMA).

Antenna System
The antenna system is constituted b y all RF transmission and reception antennas, directed to cover the same area or multi-casting configurations.
ASU
An Antenna Sharing Unit (ASU) is used for sharing RX antennas between RBSs.
BTS
A Base Transceiver Station (BTS) is a unit operating on a set of frequencies in one cell.
Basic Configuration
A basic configuration is a specified set of tran sceivers, Combining and Distribution Unit (CDU) (and in some cases) TMAs, connected to one antenna system.
A basic configuration can be multiplied or used in combina tion with othe r basic configurations to build the required site equipment.

Page 30
RBS 2106 and RBS 2206Radio Configurations
Variations of a basic configuration may exist, differing in cable lengths. This depends on factors such as implementation in different cabinets.
RBS
An RBS is all equipment in an Ericsson base station, and may be comprised of several BTSs.
Each RBS has one DXU, controlling a maximum of 12 TRXs.
SCC
The Site Cell Configuration (SCC) is a geographical concept describing how an area around one RBS site is divided into radio traffic areas. The following types of site are defined:
Omni-site
Radio coverage in one 360 degree sector, that is in one area, using one BTS.
2-sector site Radio coverage in two s ectors, that is two distinct
areas, using two BTSs.
3-sector site
Radio coverage in three sectors, th at is three distinct areas, using three BTSs.

GSM 1900 Uplink: 1850 – 1910 MHz
Downlink: 1930 – 1990 MHz
These frequency bands are supported by the configu ra tions described in this document.
5 Basic Configurations
The GSM 800, GSM 900, GSM 1800 and GSM 1900 configurations meet the GSM requirements, except where otherwise stated.
The capacity of a configuration is defined at the TX and RX antenna reference points at the RBS border. There is an X close to every reference point in the following figures. The RBS border is not included in the figures.
The equivalent output power with SW power boost (TX diversity) configured is the original output power specified for the basic configuration increased by typically 3 dB, if separate TX antennas are used. The configurations that support SW power boost are listed in Section 6.3 on page 49.
Functional views of radio signal paths for various configurations are shown in Figure 4 on page 8 up to and including Figure 21 on page 40. Only components necessary to illustrate the configuration are shown.
In some configurations, the radio signal paths can differ depending on where in the cabinet the basic configuration is used. The figures show fully-equipped cabinets with two or three BTSs, that is two or three basic configurations are shown in the s ame figure. These are different physical implementa tions of the same basic configura tion, not different configurations. The second BTS is drawn with dotted lines to show how an SCC in a fully-equipped cabinet is connected.
5.1 dTRU Topology
Configuration of Hybrid Combiner
The dTRU can be configured with or without the hybrid combiner, using two external cables.
Later versions of th e dT RU do not use external hybrid cables, see Figure 5 on
page 9.

8 Co-siting with TDMA RBS Using an ASU
The ASU is used for co-siting with a TDMA RBS, more specifically RBS 884 for 800 MHz and 1900 MHz, and RBS 882 for 800 MHz only. The unit allows a TDMA cabinet to share receiver antennas with a GSM cabinet. The ASU is installed in a dTRU based GSM cabinet .
The implementation is for 800 and 1900 MHz. The end config uration differs for different site configurations of the TDMA RBS. One-, two- and three-sector sites can be supported. In the case of two- or three-sector sites, the figures below only show one part of the RBS.
8.1 Separate TX and Two Separate RX Antennas
The original antenna configuration of the TDMA RBS is TX + RX + RX. When co-siting is configured, the antennas are moved fro m the TDMA RBS to the dTRU based RBS. The dTRU based RBS can be pre pared for co-siting alre ady at the factory. The RX paths to the TDMA RBS will go through the ASU.
By moving the receiver antennas to the dTRU based RBS , it is possible to benefit from minimum interference with the old equipment.

8.2 One Duplex Antenna RX/TX
The TDMA RBS may be equipped with only one TX/ RX antenna. Th e recommendation in this case is to add two antennas for the dTRU based RBS. One RX signal from the dTRU based RBS is supplied to t he TDMA RBS, thus adding RX diversity to the TDMA RBS.

If two separate duplex antennas are already in use, the recommendation is to install new antennas for the dTRU based RBS and not use co-siting at all.

8.4 One RX and One Duplex Antenna
If the original antenna arrange ment is TX/RX + RX, the recommendation differs for configurations where the duple x filter is mounted internally, w ithout the possibility to access the TX and RX ports separately, and configurations where the RX path is accessible.
Internal Duplex Filter
If the duple x filter is internal and the RX path is not accessible, the recommendation is to add one antenna and rebuild the configuration in the same way as in the case with TX + RX + R X in Secti on 8.1 Separate TX and Two Separate RX Antennas on page 56.

A special case is where only one TX/RX and on e RX port are accessible f ro m the o utside of the cabinet. In that case the solution stated below can be used. Note that the three duplex filters in series (one internal and two external) will degrade the TX performanc e of the co-sited RBS.

External Dup le x Filter
If an external duplex filter is used, it is p ossible to expand the configuration in two steps. The first step does not require any new antennas, but limits the number of GSM TRXs to two (that is, one dTRU) for each sector. Support of more GSM TRXs requires additional antennas.
