CI Wireless Inc. MirrorCell Select CDR812 Manual 1 General Information GENERAL INFORMATION The CDR812 is a channel-selective CDMA repeater, designed to be fully compliant with TIA/EIA/IS-95, titled “Mobile Station-Base Station Compatibility Standard for Dual Wideband Spread Spectrum Cellular System” specifications. Separate modules are used for each channel in both the transmit and receive directions. Each module selects a channel in a given direction (transmit or receive) and amplifies it.
General Information Ortel Corporation MirrorCell Select CDR1912 Manual locked to this basic oscillator. The same LO frequency is used for both the upconverter and downconverter, ensuring no difference in the input and output frequencies. An aluminum case houses the repeater. Cooling fins for the amplifier are located on the rear of the unit. The choice of aluminum as the case material gives a lightweight design with good heat conduction and weatherproof protection. The housing conforms to NEMA 4 standard.
CI Wireless Inc. MirrorCell Select CDR812 Manual 2 Description of the Major Modular Components DESCRIPTION OF MAJOR MODULAR COMPONENTS 2.1 Channel Modules Each channel module consists of a preamplifier, a baseband downconverter with SAW (Surface Acoustic Wave) filters, a baseband upconverter, and a post amplifier. The module includes power level control functionality. 2.2 Power Amplifiers The power amplifiers are designed for an output power of 12.5W (41dBm) composite .

CI Wireless Inc. MirrorCell Select CDR812 Manual 6 Description of the Control Module DESCRIPTION OF THE CONTROL MODULE 6.1 General The repeater is equipped with a status & control module, which allows the monitoring and control of various parameters such as channel number, attenuation, temperature, status of door, etc., either with a local terminal or via OMC.
Description of the Control Module CI Wireless Inc. MirrorCell Select CDR812 Manual The control module logs the number of failed login attempts. If this number exceeds the user-defined maximum (ILA, default = 8), then future login attempts will be blocked. The false login count is decreased by one each hour. This means you must wait one hour after reaching the maximum number of failed login attempts before a single login can be initiated. 6.

CI Wireless Inc. MirrorCell Select CDR812 Manual 6.11 Description of the Control Module Alarms and Alarm Configuration 6.11.1 Overview The MirrorCell Select CDMA repeater can send alarms to an Operations and Maintenance Center or to the MirrorCell Element Manager (MEM), both referred to as the OMC in this document, via a DataCall (modem connection). For each alarm sent, an end of alarm will also be sent when the end of alarm condition is detected. This does not include VLI, LGO, CLR, and ILI alarms.
Description of the Control Module CI Wireless Inc. MirrorCell Select CDR812 Manual 6.11.2 Alarm Formats Each alarm source has additional parameters sent with the alarm to the OMC, such as the severity of the alarm, the class of alarm, alarm attributes, and in some cases a textual description of the alarm. The message formats of the alarms sent to the repeater are described in the table below. These message formats apply to DataCall communications.
CI Wireless Inc. MirrorCell Select CDR812 Manual Description of the Control Module 6.11.3 Alarm Attributes The following table provides a description of each of the alarm sources within the repeater and the corresponding severity levels and class. In the parameter field, X = 0 means the attribute if OK, and X = 1 means the attribute is in error. Some of the attributes have the capability to report “-“ which indicates the piece of equipment that would normally report this alarm is not installed.
Description of the Control Module 6.11.4 CI Wireless Inc. MirrorCell Select CDR812 Manual Acknowledgment of Alarms In the case of DataCall communications, the alarm is considered to be acknowledged when the repeater has logged in to the OMC and reports the alarm. Message Field Repeater ID Message number Command Argument Argument Format XX-YY-ZZZZ NNNNN ACT ACK MMMMM Description ID of the repeater that the message is intended for. Message number from the OMC.
CI Wireless Inc. MirrorCell Select CDR812 Manual Description of the Control Module 6.11.6 Alarm Configuration Each alarm source is associated with a specific configuration string. This string provides the operator with the possibility to individually configure each alarm.

CI Wireless Inc. MirrorCell Select CDR812 Manual Description of the Control Module 6.11.7 Miscellaneous Alarm Configuration Parameters 6.11.7.1 Configuring the External Alarms The external alarms can be configured active-low or active-high. Use the following command to configure these alarms: SET EXT BC B refers to pin 1, read from EX1, and C refers to pins 2, read from EX2. B, C = 0 means that no voltage is an OK condition B, C = 1 means that a high voltage is an OK condition.
Description of the Control Module CI Wireless Inc. MirrorCell Select CDR812 Manual 6.11.7.2 Minimum Alarm Repetition Time This command has been introduced for the case where an alarm is toggling between OK and ERROR. In this state, the repeater should not continuously call the OMC with the new alarm detected for the same fault condition and potentially block the communication between the repeater and the OMC.

Installation of the CDR812 CI Wireless Inc. MirrorCell Select CDR812 Manual less than 15° are ideal candidates for the donor antenna. Microwave dish antennas also provide the recommended front-to-back ratio of greater than or equal to 25dB to help achieve the required antenna isolation. The server antenna should provide the desired coverage and also provide the recommended front-to-back ratio of 25dB.
CI Wireless Inc. MirrorCell Select CDR812 Manual 7.4.2 Installation of the CDR812 Server Antenna Mounting and Isolation Measurements Isolation measurements should be taken to ensure proper operation of the repeater. Measurement of isolation can be accomplished easily by following the procedures, as illustrated in Figure 15. 1. Mount server and donor antennas at initially chosen location to obtain desired coverage. 2. Inject a known signal within the bandwidth of operation into the donor antenna.
Installation of the CDR812 CI Wireless Inc. MirrorCell Select CDR812 Manual Antenna isolation can be measured once the donor and server antennas have been mounted at their initially desired location. Isolation measurement is important in properly setting up a repeater. 4. The repeater gain can be set to at least 10dB below the figured measured above. (The antenna isolation must be at least 10dB greater than the repeater gain.
