CTU Rx function The receiver part of the CTU accepts two amplified and filtered receive antenna signals from the SURF module.
GSM-205-323 CTU CTU Tx function IQ modulator Figure 5-6 shows a functional diagram of the IQ modulator. IQ modulator data for eight timeslot channels is applied to the modulator state machine. This data is encoded, serial-to-parallel converted and split into quadrature components. The quadrature components are D/A converted and applied to a quadrature modulator to create a Gaussian minimum shift keyed (GMSK) carrier at an intermediate frequency (IF).
GSM-205-323 CTU Power amplifier board Figure 5-8 shows a functional diagram of the power amplifier (PA). The PA board provides amplification and a forward power detector. The isolator protects the PA board amplifiers. The detected output is used to adjust the final CTU RF power output level by the digital sections of the XCVR. The PA board consists of six functional blocks: RF power amplifier. RF forward power directional coupler. RF forward power detector. Temperature sensor.
GSM-205-323 CTU CTU digital processing and control functions The CTU digital processing and control function provides control and RF processing for that CTU. These functions include: 2.048 Mbit/s links which interface with up to two MCUFs for redundancy. A software processing platform for the radio sub system (RSS) A digital signal processor (DSP) for radio control and channel equalization (EQCP). A DSP for channel coding, data routeing, and baseband hopping (CCCP).
GSM-205-323 CTU 2 Mbit/s TDM links The CTU interfaces to the redundant MCUF are by 2.048 Mbit/s links on the backplane (or FMUX modules in extension cabinets). These links are Manchester encoded, thus providing both clock and data in a single connection. The recovered clock provides a frequency reference for the CTU. The Rx and Tx circuitry supports FMUX fibre optic lengths of up to 1 km. The TDM links are formatted into 32 x 64 kbit/s timeslots to provide: Downlink and uplink TRAU speech data.
GSM-205-323 CTU CCCP processor The CCCP processor handles all the GSM specified layer 1 channel encoding and decoding functions for speech and control data associated with the air interface. In addition, it manages the routeing of TRAU frames and baseband hopping (BBH) data, via the TDM interface, to and from the MCUF. The CCCP functions include: Uplink channel decoding. Downlink channel encoding. GSM specified encryption algorithms.
GSM-205-323 CTU CTU uplink/downlink Downlink traffic data flow Downlink TRAU data from the MCUF is received by the TDM function then routed to the CCCP function where it is encoded (cyclic, block, and convolutional), interleaved, and encrypted to GSM recommendations. Signalling messages are also received from the RSS processor and encoded. These traffic and control messages are built into air interface frames and then routed back to the MCUF via the TDM function for baseband hopping.
GSM-205-323 CTU frequency hopping CTU frequency hopping Overview of CTU frequency hopping The CTU supports two types of frequency hopping, synthesizer frequency hopping (SFH) and baseband frequency hopping (BBH). This section provides an explanation of both types. In either type, the MS switches channels after every transmit/receive (Tx/Rx) burst pair. The difference between SFH and BBH is in the method by which channel switching is achieved at the BTS.
GSM-205-323 CTU frequency hopping SFH example not through BCCH CTU 0 In this example of SFH, CTU 0 provides the BCCH and cannot frequency hop. CTU 0 has to transmit at maximum cell site power to meet the BCCH requirement. Timeslots are used as shown below: TS 0 = Combined BCCH TS (BCCH/CCCH/DCCH). Transmitted at maximum cell site power. TS 1-7 = Traffic channels, all non-hopping. All traffic channels transmit at maximum cell site power.
GSM-205-323 CTU frequency hopping Baseband frequency hopping (BBH) BBH requires all eight timeslots of the CTU Tx (downlink) at the same frequency. In the Rx (uplink) direction, the frequency agility of the CTU is used to change timeslot frequencies on a timeslot basis. The BCCH frequency is always transmitted at maximum cell site power. BBH can use either Tx blocks or CCB Tx combining equipment.
GSM-205-323 CTU frequency hopping Transmit The transmit is described by the following, as shown in Figure 5-12: 1. Traffic data from the network is passed through the NIU to the MCUF. Within the MCUF an ASIC switches the data to CTU0 (the dedicated CTU for this particular MS call example). 2. The CTU, having processed the data (channel coding, interleaving, encryption and routeing information) then passes the data back to the ASIC. 3.

GSM-205-323 Overview of digital modules Overview of digital modules Overview and redundancy Digital modules provide the Horizonmacro indoor equivalent of M-Cell6 micro base control unit (µBCU) functionality. They are located in the bottom right side of the CIBA maincage, and are electronically interconnected through the backplane. Fibre optic connections are at the front of the appropriate modules.
GSM-205-323 Overview of digital modules MCUF and NIU redundancy The digital module shelf can: Support two MCUFs at a BTS site, one master and one slave (for redundancy). Enable Master MCUF failure to result in the slave MCUF becoming the master after reset. Enable the OMC-R operator to initiate master/slave MCUF swap. Configure CTUs by the master MCUF. All four NIUs operate from the master MCUF, but each pair of NIUs depend on a BPSM for power. All NIUs configure to the master MCUF clock.
GSM-205-323 Overview of digital modules Digital module and CTU connections The MCUF is connected to the CTUs in the same cabinet through the backplane. Optional connection to CTUs in up to three additional cabinets (six CTUs per cabinet) is by fibre optic links. FMUXs, two internal to the MCUF and one half size module, convert the electronic data stream into a fibre optic signal.
GSM-205-323 MCUF MCUF MCUF overview The main control unit with dual FMUX(MCUF) provides the site processing functions, apart from RF functions of the transceiver. The MCUF also provides switching for up to six network interfaces (via four NIUs) and up to 24 transceivers. The cabinet may contain up to two MCUF modules, (one master and one for redundancy). Each site and module has an electronic ID for remote identification.
GSM-205-323 MCUF GPROC TSW and GLCK functions The MCU section of the MCUF module combines functions of older generation equipment: The BTP (Base Transceiver Processor) functions and CSFP (Code Storage Facility Processor) functions (provided PCMCIA card fitted), formerly achieved by generic processor boards (GPROCs). The timeslot switch (TSW). The generic clock (GCLK). MCUF module view Figure 6-3 shows an MCUF module.
GSM-205-323 MCUF MCUF functional diagram Figure 6-4 shows a functional diagram of the MCUF. (IF USED) (IF USED) Figure 6-4 Functional diagram of MCUF in MCUF mode Tech.
GSM-205-323 MCUF Link to redundant MCUF The link to the redundant MCUF is similar to a transceiver link, but does not have the BBH capability, or the link delay measurement and compensation facility. The 6.12 s, and 60 ms signals, are inserted into timeslots 8 and 16. When the MCUF is in slave mode, timeslot and E1/T1 clock information is extracted from the MCUF link and passed to the sync block. The main processor HDLC link to the redundant MCUF can be routed in any unused timeslot(s) of this link.
GSM-205-323 MCUF PCMCIA interface The PCMCIA card is located on the front panel of the MCUF, and is used for: Code Storage Facility Processor (CSFP) memory. Rapid site initialization. The PCMCIA socket is an industrial standard 68 pin single socket, fitted with an ejector. The PCMCIA interface supports rev 2.1 type I and II cards. The 20 Mbyte card can be write enabled, for upgrade of site information, or disabled to protect card use for other sites or secure the site code.
GSM-205-323 MCUF PIX interfaces The MCUF provides four PIX outputs on the backplane, driven at V. 28 levels. The four PIX outputs, routed to the cabinet alarm board, enable relay contact control of external customer equipment. DRAM, flash EPROM and code loading functions DRAM The 16 Mbyte DRAM provides operational code and data storage for the main processors. There is also a SIMM socket in the circuit board, enabling the addition of a further 16 Mbytes if required.
GSM-205-323 MCUF ASIC functionality The Application Specific Integrated Circuit (ASIC) provides central switching capabilities for the MCUF. It is capable of supporting up to 24 transceivers, together with up to six network interfaces and two links to the on-board processors, one link to the sync processor and a link to the redundant MCUF. The link to the sync processor is used for code loading purposes only. The ASIC supports baseband hopping across the 24 transceiver links.
GSM-205-323 MCUF ASIC/network and processor link switching The ASIC supports a maximum of six network links and two main processor links. The data to/from these links can be switched to/from any timeslot on other links connected to the ASIC. The two links to the main processor allow it to route HDLC and other links to the appropriate place: 24 HDLC timeslots for the BCF RSS channel to each transceiver. Four timeslots for NIU control channels (two local, two redundant).
GSM-205-323 MCUF Phase lock loop (PLL) operating modes The PLL uses the selected reference signal as the loop reference clock. It includes an OCXO accurate to 0.05 ppm, a phase comparator and a loop filter. The PLL has the following operating modes: Warm-up The PLL is open loop and using the calibration frequency, but the OCXO is not yet warmed up. Set frequency The PLL is open loop and using the calibration frequency, and the OCXO is warmed up.
GSM-205-323 MCUF Integral MCUF FMUX functionality The equivalent function of two FMUX modules exists integral to the MCUF, enabling two extension cabinets to be connected. To enable total of four cabinets to be joined together as one BTS site, an FMUX module is also required in the master cabinet to connect the third extension cabinet. A single cabinet site has no need for the FMUX functionality, because the MCUF connects with the cabinet CTUs through the backplane.
GSM-205-323 NIU NIU Overview of NIU The network interface unit (NIU) module provides two E1 or two T1 termination links to the terrestrial network. The NIU E1/T1 outputs are connected to a T43 or BIB board, depending on the impedance matching requirement of the customer terrestrial circuits. There are two types of NIU board, one for E1, one for T1. The NIU layout is common to both E1 and T1, the only differences being in the associated crystal oscillators and line matching resistor values.

BTS architectures and interoperability GSM-205-423 Technical issues When mixing different BTS types, the interface may be required to resolve some or all of the following issues, depending on the site configuration: The interface must deliver both Rx and Rxdiv (receive diversity) signals to each transceiver. The interface must not change the uplink (receive) signal level delivered to any transceiver.
GSM-205-423 BTS architectures and interoperability DCS1800 Refer to Figure 3-4. In the Horizonmacro cabinet, low noise amplification in the SURF module first boosts the Rx signal by +13 dB. Separate Rx outputs from the SURF are then discretely routed to relevant transceivers in the master cabinet, and to the LNA in the extender cabinet.
GSM-205-423 BTS architectures and interoperability GSM900 Refer to Figure 3-5. In GSM900 products, RF gain for the IADU and SURF is configurable. A split cell configuration is therefore dealt with in the same way as that described for DCS1800, except that the 13 dB attennuators are not required. Instead, the required signal level is maintained by using appropriate gain settings for the IADU and SURF.
GSM-205-423 BTS architectures and interoperability Transmit path M-Cell6 combining When configuring the downlink paths for a cell using three carriers or more, it may be necessary to provide additional external RF load(s) for the combiners. This is illustrated by Figure 3-6, which shows a typical M-Cell6 combining arrangement for a 4-carrier cell.
GSM-205-423 BTS architectures and interoperability Horizonmacro combining A similar arrangement is used in the Horizonmacro, which uses a Hybrid Combiner Unit (HCU) and Dual stage Duplexed combining Filter (DDF), as shown in Figure 3-7. The DDF has three input ports together with two internal RF loads, and therefore does not require the addition of any external load.
GSM-205-423 BTS architectures and interoperability Mixed equipment combining When the two different product types are interfaced, a situation can arise where a 3IP CBF is connected to an HCU, as shown in Figure 3-8. In this configuration it is therefore necessary to provide an additional external RF load for this 3IP CBF. The example in Figure 3-8 shows downlink connections for a 4/4/4 configuration using mixed BTS types.
GSM-205-423 BTS architectures and interoperability M-Cell6 and Horizonmacro hardware equivalents Table 3-2 shows the RF hardware equivalents for the Horizonmacro and M-Cell6 BTSs.
GSM-205-423 BTS architectures and interoperability Example configurations Configuration diagrams provided by the Motorola local office show top of rack cable and antenna connections for mixed product configurations, together with details of external RF loads required. Figure 3-9, Figure 3-10 and Figure 3-11 are examples of the type of diagram that can be provided.
GSM-205-423 BTS architectures and interoperability GSM900 5/5 configuration using two cabinets In this configuration, there are no split cells, and therefore no uplink or downlink connections between the cabinets. In the M-Cell6 cabinet, both 3IP CBFs are configured with external loads provided by the NON HYB. In the Horizonmacro, one DDF has two direct RF inputs, plus a third input via the FEEDTHRU. The second DDF has two RF inputs, one direct and one via the FEEDTHRU.
GSM-205-423 BTS architectures and interoperability DCS1800 4/4/4 configuration using two cabinets In this configuration, sector 2 is split between the cabinets. The uplink Rx and Rxdiv signals for sector 2 are therefore connected between the BTS types to ensure the availability of both signals in both cabinets. In the M-Cell6 cabinet, 2-input hybrids are used for combining, each configured with a discrete external load.
GSM-205-423 BTS architectures and interoperability Special hardware A range of cables is available for uplink, downlink and fibre optic connections, together with the uplink attennuators described earlier. Contact the Motorola local office for further details. In addition, the mounting plate and snap-in multi cable gland shown in Figure 3-12 are required when expanding M-Cell6 outdoor sites with Horizonmacro cabinets.
