Activate the CLI by clicking on a shortcut icon on the desktop. The CLI can not be launched from the GUI, only from the desktop icon. Both the GUI and the CLI use a program known as the handler. Only one handler can be running at one time. Due to architectural limitations, the GUI must be started before the CLI if you want the GUI and CLI to use the same handler. When the CLI is launched after the GUI, the CLI automatically finds and uses an in–progress login session with a BTS initiated under the GUI. This allows the use of the GUI and the CLI in the same BTS login session. If a CLI handler is already running when the GUI is launched (this happens if the CLI window is already running when the user starts the GUI, or if another copy of the GUI is already running when the user starts the GUI), a dialog window displays the following warning message: The CLI handler is already running. This may cause conflicts with the LMF. Are you sure you want to start the application? Yes No This window also contains Yes and No buttons. Selecting Ye s starts the application. Selecting No terminates the application. CLI Format Conventions The CLI command syntax is as follows: Sverb Sdevice including device identifier parameters Sswitch Soption parameters consisting of: – keywords – equals signs (=) between the keywords and the parameter values – parameter values Spaces are required between the verb, device, switch, and option parameters. A hyphen is required between the device and its identifiers. Following is an example of a CLI command. measure bbx–<bts_id>–<bbx_id> rssi channel=6 sector=5 Refer to LMF CLI Commands for a complete explanation of the CLI commands and their usage. 3 Using the LMF 68P09258A31–A Oct 2003 1X SCt 4812T BTS Optimization/ATP 3-26 Logging into a BTS Logging into a BTS establishes a communication link between the BTS and the LMF. An LMF session can be logged into only one BTS at a time. Prerequisites Before attempting to log into a BTS, ensure the following have been completed: SThe LMF is correctly installed on the LMF computer. SA bts-nnn folder with the correct CDF/NECF and CBSC files exists. SThe LMF computer was connected to the BTS before starting the Windows operating system and the LMF software. If necessary, restart the computer after connecting it to the BTS in accordance with Table 3-5 and Figure 3-3. CAUTION Be sure that the correct bts–#.cdf/necf and cbsc–#.cdf file are used for the BTS. These should be the CDF/NECF files that are provided for the BTS by the CBSC. Failure to use the correct CDF/NECF files can result in invalid optimization. Failure to use the correct CDF/NECF files to log into a live (traffic–carrying) site can shut down the site.

IHET5BP1 FCC Filing- SC4812-MF 1X @ 800 MHz CDMA BTS 1 of 13 DESCRIPTIVE INFORMATION FCC FILING FOR SC4812-MF 1X @ 800 MHz CDMA BTS The Information in this exhibit is in accordance with the FCC Rules and Regulations, Vol. II, Part 2, Subpart J. Sections 2.1033 through 2.1055 are addressed. Section 2.1033 (a) Name of Applicant and Manufacturer: MOTOROLA Section 2. 1033 (b) Identification of Equipment: IHET5BP1 Section 2. 1033 (c) Quantity Production: Quantity Production is planned. Section 2. 1033 (d) Technical Description This Transmitter is intended for use in the Public Cellular Radio Telecommunications Service and is designed in compliance with the FCC Rules and Regulations Title 47, Part 22(H). This transmitter is capable of spread spectrum (CDMA) operation, and allows up to 128 Walsh codes to support Pilot, Sync, Paging, Supplemental, and Traffic channels. (1) Types of Emissions This equipment will be capable of operation using wide band spread spectrum techniques employing Direct Sequence Code Division Multiple Access (DS-CDMA) digital communication techniques. For this transmitter, the emission designator is 1M30F9W (per FCC Part 2.201, subpart C). (2) Frequency Range This transmitter operates within the 869.70 to 893.31 MHz Band for 1X operation (per FCC Part 22). This base station will support CDMA operations on channel numbers 1013 through 1023 and 1 through 777 inclusive for 1X operation. (3) Range of Operating Power The rated maximum average power out of the SC4812-MF 1X @ 800 MHz CDMA BTS is .063mW (-12 dBm) per RF carrier. However, in CDMA the actual power output is based on the number of traffic channels in operation. The minimum power occurs when only a pilot signal is present. The maximum power occurs when a pilot along with synchronization, paging, and traffic IHET5BP1 FCC Filing- SC4812-MF 1X @ 800 MHz CDMA BTS 2 of 13 (3) Range of Operating Power (cont.) channels are present. For a typical system setup, the theoretical difference between minimum power and maximum power is about 8 dB. The output power is variable in 0.25 dB steps. In addition, the dynamics of a CDMA system allow for what is called “cell breathing”. This allows an operator to vary the range of a cell by controlling the power of the pilot signal. (4) Maximum Power Limits The peak output power of a base station transmitter may not exceed 500 Watts as defined in Part 22.913(a). (5) Applied voltages and currents into the final transistor elements of the transmitter output: The applied voltages and currents into each of the Linear Power Amplifier’s final transistor elements are as follows: Drain 27.0 VDC Drain Current 1.0 AMPS Gate Voltage 4 VDC (6) Function of Each Active Device Refer to the Operational Description Exhibit. (7) Complete Circuit Diagrams Refer to the Schematics Exhibit. (8) Instruction/Installation Manual Refer to the Installation Manual Exhibit. (9) Tune-Up/Optimization Procedure Refer to the Users Manual Exhibit. IHET5BP1 FCC Filing- SC4812-MF 1X @ 800 MHz CDMA BTS 3 of 13 (10) Means for Frequency Stabilization Refer to the Test Report Exhibit. The Clock Synchronization Module (CSM/CSM2) provides clock and time signals for an SC4812-MF 1X @ 800 MHz CDMA BTS. In addition, it provides the primary source, a 3 MHz clock, for the transmit synthesizer in the Broadband Transceiver. The CSM/CSM2 relies on a GPS receiver, either riding piggyback onto the CSM/CSM2 card or remotely located in an integrated package with the GPS antenna as the primary time reference for the ovenized oscillator. Two types of redundancy are provided: 1) Dual CSM/CSM2 cards provide redundancy in case of primary CSM/CSM2 failure. 2) Redundancy is also provided by either a High Stability Oscillator (HSO) or a Low Frequency Reference (LFR), such as a Loran C receiver, residing in a separate slot. The HSO is provided in case of GPS system failure. The CSM/CSM2 uses the received signals as a reference to provide the required clock for the site. The CSM/CSM2 distributes CDMA time, a 19.6608 MHz clock, and a two second synchronization pulse every even second of universal time to the CDMA Clock Distribution (CCD) Cards . The CSM/CSM2 is also responsible for configuration and management of the GPS and LFR systems. CSM/CSM2 software determines on a site basis what the GPS and LFR configurations should be. For future Commercial CDMA systems, GPS and LFR configuration information could optionally be downloaded to the CSM/CSM2 from the GLI2. The CSM/CSM2 is managed by the GLI2. The High Stability Oscillator (HSO) or Low Frequency Time Reference (LFR) is used to provide a stable time reference in case of a GPS system failure or shutdown. The output of the LFR card is routed to the CSM/CSM2 cards, which derive the appropriate time references for the RF section. The current LFR is a LoranC receiver. In areas where LoranC is unavailable, the HSO may be used. IHET5BP1 FCC Filing- SC4812-MF 1X @ 800 MHz CDMA BTS 4 of 13 (11) Means for Attenuation of Spurious Emissions Refer to the Test Report Exhibit. Bandpass filters are employed in the transmit RF circuit to attenuate far out spurious emissions. The filter used here is of an air dielectric cavity resonator type. In addition to the digital filters described below, the baseband also employs a discrete anti-alias filter that attenuates signals greater than 2MHz. Out of band emissions are also attenuated by ceramic filters in the transmit RF lineup. In addition, suppression of spurious radiation is obtained by proper shielding techniques. Means for Limiting Modulation Refer to the Test Report Exhibit. In a CDMA system, the input signal (voice for example) is sampled and coded in a vocoder. This signal is then spread to approximately 1.28 MHz by a pseudo-random spreading code. This spreading code sets the bandwidth of the spread-spectrum signal. If more than one signal is in operation (i.e. more than one channel), then the two signals are simply layered one atop the other within the 1.3 MHz ba…
