Refer to the RBS 884 Site Engineering Manual for descriptions of the available working base station configurations and for information on RBS interfaces (for instance, power, transmission, and antennas). Features The RBS 884 Series is a series of products in the CMS 8800 family. The products in the RBS 884 Series are fully featured modular RBSs for both the analog AMPS EIA 553 and the digital D-AMPS EIA IS 136 systems (Advanced Mobile Phone System Electronics Industry Association 553 system and Digital American Mobile Phone System Electronics Industry Association Interim Standard 136 system). A base station in the RBS 884 Series can support one, two, or three cells. A cell is a defined area covered by one antenna system, and each cell has one control channel for digital or one for analog, or both. There is one cell at an omni site, and one to three cells at a sectorized site. The RBS 884 Series utilizes multi-mode, multi-functional transceivers (TRXs). The same hardware TRX module can be used for analog and digital voice, control and monitoring purposes. The hot repair capability allows replacement of defective units when power is still applied. The RBS 884 Series is designed for remote control monitoring allowing control and fine tuning of all functions and parameters, such as power output, frequencies, and switching of redundant units from the MSC. A Radio Frequency Test Loop (RFTL) is an optional feature that enables precise output power settings, Voltage Standing Wave Ratio (VSWR) alarm, and Receive Signal Strength Indicator (RSSI) test measurements. The device software is stored in non-volatile memory within the RBS, and the control part software is downloaded from the MSC, which ensures a short time to service at power-up. 1/1551 AE/LZB 119 4239 Uae Rev PRELIM 2001-03-15 2-3 General Product Information Product Lines RBS 884 Micro (1900 MHz) RBS 884 Macro with MCPA, 850 MHz RBS 884 Outdoor RBS 884 3 R 1 PLIFIE AM OFF ON 3 R 1 PLIFIE AM 3 R 1 PLIFIE AM OFF ON OFF ON 3 R 1 PLIFIE AM OFF ON OFF ON RBS 884 Micro 800 OFF ON OFF ON OFF ON 3 R 1 PLIFIE AM OFF ON 3 R 1 PLIFIE AM OFF ON OFF ON OFF ON RBS 884 Macro with MCPA, 1900 MHz Figure 2-1. 2-4 RBS 884 High Capacity Self-Contained Cell Site Product Lines in the RBS 884 Series 1/1551 AE/LZB 119 4239 Uae Rev PRELIM 2001-03-15 General Product Information The RBS 884 Series includes product lines for macro and micro cells.

RXA RXB DEVCB CRI and TCB Functional Block Diagram The Exchange Terminal Boards (ETBs) end the PCM links and connect the RBS to the MSC. The control signals for the RBS are carried on one time slot of the PCM link, and are ended by the Signal Terminal Receiver (STR). A set of Extension Module Regional Processor Speech Bus Interfaces (EMRPSs) is used to control the devices on a load sharing basis. Communication Links (C-links) connect device equipment (TRX, ALM, RFTL, and TIM) to the Radio Transceiver Terminals (RTTs). A Node Clock Time Switch (NTSW) connects control paths from the EMRPSs to the devices. The time switch also routes the traffic data on paths set up between a time slot on an ETB and a device connected to an RTT. The time switch is controlled by a dedicated EMRP. The received RF signal is split to all Transceiver modules (TRXs) by the Power Splitters (PSPs) and the Power Splitter backplane in the Transceiver Cabinet (TCB).The RF output from the TRXs are connected to the HCC. Figure 3-7 on page 3-11 is an example of unit interaction in the HCC and ANPC.

It is then fed to the Multicoupler A (MC A) and B (MC B) units, where the signal is amplified to compensate for Power Splitter (PSP) losses. The multicouplers also receive signals from the Radio Frequency Test Loop (RFTL) unit so that the receive path can be tested. Multicoupler outputs are fed to the PSPs, which distribute the signals to the TRXs through the TCB backplane. Each TRX receives both A- and B-branch receive signals and demodulate the signals to baseband. TRX transmit outputs are connected to the combiners where they are combined into one signal. This signal is directed to the MCPA, Transmitter Bandpass (TXBP) filter, and Measurement Coupler Unit (MCU), after which it is output to the antenna. The MCU acts as an interface to the Radio Frequency Test Loop (RFTL), which performs various tests on the RF signals, such as measuring forward and reflected power. 2/1551-AE/LZB 119 4239 Uae Rev A 2001-03-15 3-11 System Description 3.2 Call Paths 3.2.1 Receive Path As shown in Figure 3-8 on page 3-12, the received signal is passed through the Receiver Bandpass (RXBP) filters in the TMAs (if used) and ANPC.
