CONFIDENTIAL AND PROPRIETARY 15 stand-alone microcell base transceiver station (BTS) in the integrated Dispatch Enhanced Network (iDEN) that simultaneously supports the 800E and 900 MHz bands with the necessary Tx amplification to achieve +36 dBm per carrier. The three-sector configuration supplies twelve full-duplex iDEN carriers per sector, or the equivalent of up to 36 Base Radios (BRs) per site. The MC-Series High Power system supports two-branch receive diversity. The system interfaces with the Mobile Switching Office (MSO) via a standard T1 interface, which also provides the Operations and Maintenance Center (OMC) with alarm information and enables the OMC to remotely control and configure system operations via a standard site datafill. Operation of an MC-Series High Power system requires the use of Multi-channel RadioBlade (MCRB) transceivers. The MCRB duplicates the RF functions of up to 6 simultaneously operational iDEN radio transceivers, supporting six corresponding Transmit (Tx) – Receive (Rx) channel pairs with full-duplex operation. In the case of MCRBs used for diversity, the transmitter is not utilized. The MC-Series high power system is shipped ready to install and configure. The system is enclosed in a single 19” equipment cabinet containing all RadioFrame Networks equipment as well as the two required iSC3s and the required EAS. The customer provides the required CSU and is responsible for T1 connectivity, datafill (network provisioning), antenna system, GPS (as required by iSC), electrical supply, any needed additional environmental cooling, and the necessary permitting.

TRADE SECRET INFORMATION Figure 18 MCRB Label Position 2.2.4.3 Combined RadioBlade Transceivers in an RBS The MCRB allows up to 6 BRs to be assigned to a single physical RadioBlade transceiver with a requirement applied that all carriers need to be within the same 1.25 MHz band. Because of this requirement, all frequencies need to be known prior to the programming of the MCRB. To accommodate this, all BRs set up in the iDEN configuration page will register with the network to get assigned frequencies. Once the frequencies are known, and the available HW resources are known, the carriers are assigned to the MCRBs and single-channel RadioBlade transceivers by the following rules: 1) Any 900 MHz BRs will be assigned to an MCRB. 2) The largest group of carriers which fall within the 1.25 MHz band is assigned to the MCRB if one is available. (Note: This process repeats until there are no remaining unassigned MCRBs.) 3) Any carriers that remain unassigned are assigned to single-channel RadioBlade transceivers. 4) If any carriers are still unassigned, an alarm is sent to the OMC. 5) If any MCRBs or single-channel RadioBlade transceivers are unassigned, they become standby blades. 2.2.5 High Power Dual-Band RF Shelf The MC-Series system provides one RF shelf per sector. The RF shelf contains amplifiers, filters, combiners, redundant DC-DC converters and fans to provide cooling to the power amplifiers (PAs). The transmit chain includes a software-controlled variable attenuator for adjusting the Tx power output at the top of the cabinet, a multi-channel linear power amplifier (PA), a band

MC-Series High-Power System System Definition 998--01 Rev X1 RadioFrame Networks, Inc. CONFIDENTIAL AND PROPRIETARY 27 pass filter and a sampling port. The Tx sampling port provides approximately top of the rack (TOR) minus 20 dB output power. The Tx power output at the top of the rack can be varied by changing the datafill. The PA is sized to allow sufficient linearity and gain such that a minimum of +29 dBm per carrier (up to 12 carriers) can be achieved at the top of the rack. The sampling port signal is brought out to the front of the RF shelf to provide monitoring and testing of the transmit path. The receive path contains a band pass filter, low noise amplifier (LNA) and a sampling port. As with the Tx sampling port, the Rx sampling port is brought out to the front panel of the RF shelf. The Rx sampling port provides approximately top of the rack (TOR) minus 20 dB output power.

MC-Series High-Power System Management—Datafill, Configuration and Optimization 998--01 Rev X1 RadioFrame Networks, Inc. CONFIDENTIAL AND PROPRIETARY 57 6 Management—Datafill, Configuration and Optimization This section describes configuration techniques that affect the behavior of the MC-Series High-Power system. Section 6.1 covers the datafill parameters as they differ from the Motorola EBTS. Section 6.2 covers configuration options using System Manager, with sections 6.2.1 and 6.2.2 introducing basic operations and 6.2.3 presenting optimization procedures. 6.1 Datafill The MC-Series High-Power system is designed for compatibility with the Motorola EBRC and QUAD Base Radios (BRs). However, due to architecture differences between the two systems, not all datafill parameters apply equally to the MC-Series High-Power system. This section describes only those datafill parameters that need to be taken into consideration when used with the MC-Series High-Power system. Any datafill parameter not described here can be assumed to behave identically to the Motorola EBTS. This section includes: 6.1.1 Parameters that RFN does not support 6.1.2 Parameters that have no effect on the MC-Series High-Power system 6.1.3 Parameters that RFN supports, but which need to be setup differently from the typical setup for a Motorola BR 6.1.1 Unsupported Datafill Parameters The following datafill parameters are currently not supported. 6.1.1.1 steThresholdMode The Slot Timing Error Threshold Mode parameter has three different purposes: • Setting to zero allows the EBTS to automatically determine the STE threshold based on history of inbound transmissions. • Setting to maximum value of 250 essentially disables the use of STE filtering. • A manual override exists by setting the parameter in the range of 1 to 249. The default value is set to 250. This datafill parameter will be supported in the MC-Series High-Power system starting with 15.0 releases of System Manager software. 6.1.1.2 brPwrReducModeAcg The BR Power Reduction parameter is used to enable/disable the Power Reduction feature on a per-BR basis. The default value is set to 'ON' and it is on-line changeable. This feature will be supported in the MC-Series High-Power system starting with 15.0 releases of System Manager software. 6.1.2 Parameters that Do Not Apply to the MC-Series High-Power System The following parameters have no effect on the MC-Series High-Power system. There is no functional equivalent in the MC-Series High-Power system, and as such the parameters can be ignored.

Management—Datafill, Configuration and Optimization MC-Series High-Power System 998--01 Rev X1 58 CONFIDENTIAL AND PROPRIETARY RadioFrame Networks, Inc. TRADE SECRET INFORMATION 6.1.2.1 combinerType This parameter specifies the type of combiner used to connect the cells Base Radios to the antenna. The options are hybrid and cavity. The MC-Series High-Power system is similar to a cavity type combiner physically but it does not have the same frequency limitations as the cavity combiner that this parameter is used for. 6.1.3 Recommended Datafill Parameters The following parameters need to be set differently than what is currently set with Motorola BR. These settings are not required but recommended for best operation. 6.1.3.1 PCC The power control constant is broadcast on the BCCH and is used by the MS to calculate a target value for its transmit power. For Indoor Pico and Micro-Cell applications this value will vary depending upon the RF environment (i.e., if used outdoors the value will be quite different from an indoor scenario). For the MC-Series High-Power system, the setting of this parameter depends on what is connected between the MC-Series High-Power system and the antenna. The default value should be calculated in accordance with Motorola guidance detailed in the Datafill Parameter Guide. It should be noted that in cases in which the Mobile subscribers are near the antenna source (downlink limited), the handsets could transmit at a much lower level than is the case with a Macro site. Lowering this parameter forces the mobile to operate at fairly low Tx level thus conserving battery life. In cases where the MC-Series High-Power system is connected to a DAS, the gains and losses of the paths should be taken into consideration. Additionally the level of uplink interference should be considered when determining this value. 6.1.3.2 Pto (transmit power) The Cells outbound transmit power referenced at the output of the RF Distribution System Antenna Port. It is used as a reference point value when computing the link budget of the system. RFN recommends that the value of this parameter be set appropriate to the TOR output power, which is determined by the defaultTxPower parameter (see below). 6.1.4 rxTxGain = 0 This parameter is the difference in gain between the receiver and transmit antenna paths expressed in dB. The MC-Series High-Power system does not use this parameter directly. 6.1.4.1 defaultTxPower Note: Refer to release notes for range information. This is the average output power of the PA, measured at the RF connector of the BR. For the MC-Series High-Power system, this parameter can be used to adjust the output power of the system. The gain at the shelf is fixed and cannot be altered as was the case with the 800-only RF Shelf. The MC-Series High-Power system has a different range of output levels than a standard Motorola EBTS, and as such, these values will map to a different set of actual Tx output power levels. (The correspondence is shown in Table 16 in section 2.5.8.3 .) The nominal maximum Tx power at the top of the rack with a maximum variation of ± 2 dB is +29 dBm. The dynamic range is 11 dB.

TRADE SECRET INFORMATION 7.5 System Manager Alarms The MC-Series system provides fault alarming and isolation within System Manager for individual components, which consists of detecting catastrophic faults that prevent a component from responding to a periodic “ping”. Depending on the severity, alarms are sent to the OMC via the iSC-3. The Alarms/Events Reference Guide, included on the MC-Series CD and available on the RadioFrame Networks website, lists the alarms by ID code. All alarms passed to the OMC use the Sprint Nextel Alarm Code 35009, which uses the event description “Unable to key BR”. 7.5.1 Viewing System Manager Alarms 1 Select the Alarms tab in System Manager to display the Active Alarm Manager. The Alarm Log displays active (un-cleared) alarms listed by date and time, and the Alarm Details window displays information about a single selected alarm (see Figure 50). A summary at the top of the page lists the current number of Critical, Major, Minor, and Warning alarms. Alarms that are no longer active are moved to the Alarm History Manager. Note: If the Alarms page is empty, System Manager is still loading the page. Non-alarm events are displayed in the Events Log. The initial Events Log lists all the alarms generated by RFS components. You can view a smaller list by selecting one of the Show links at the bottom of the page. Clicking the first link with a value of 20 in the box displays the first 20 alarms. You can enter any number in the field.

TS/BR 7.5.3 System Manager Alarms The document Alarms/Events Reference Guide lists MC-Series system alarms numerically by alarm ID (0x01, 0x02, etc.). MC-Series alarms are based on the X.733 conventions for telecommunications equipment. The alarms are grouped by service: either “asp” for platform faults or “iden” for iden application faults. The “cause” field contains the X.733 cause type. “System reaction” describes the action taken by the system as a result of this alarm, and “repair actions” provides details on what corrective action should be taken as a result of this alarm. The Alarm details on the active alarm manager page of System Manager provides additional information with respect to the board, slot number, MAC address and equipment type. 7.6 RadioBlade Transceiver Alarm Handling The iDEN RadioBlade transceivers track various faults and reports to the RadioBlade controller. These faults are monitored, and if the rate at which these faults occur surpasses a threshold, the RadioBlade transceiver (blade) is locked. The blade will generate these faults as the result of normal actions such as re-syncing the blade, locking and unlocking the blade and locking and unlocking the BR. For these reasons, only if the blade continues to generate these faults under normal operating circumstances is an alarm generated. The RadioBlade transceiver tracks the faults listed in Table 28. Table 28 Faults Tracked by the Transceiver Fault Description PLL1 Errors The Phase Lock Loop #1 went out of lock. PLL2 Errors The Phase Lock Loop #2 went out of lock. PLL3 Errors The Phase Lock Loop #3 went out of lock. Tx Underrun RadioBlade transceiver did not receive a packet in time to transmit.

TRADE SECRET INFORMATION Tx Overflow RadioBlade transceiver received too many packets to transmit. Rx OverFlow Sample buffer overflowed. Slot mismatch Received packets were not consecutive. CRC errors Received Ethernet packets had CRC errors. If a RadioBlade transceiver generates enough errors such that it crosses the Bounce and Duration threshold for that particular error, an alarm will be generated. This alarm will also cause the RadioBlade Locking Policy to lock that RadioBlade transceiver. Table 29 lists the fault count and fault period for an alarm to be generated. Table 29 RadioBlade Transceiver Fault Thresholds for Alarm Generation Alarm Bounce Threshold (counts) Duration Threshold (minutes) PLL 1 75 12 PLL 2 75 12 PLL 3 50 12 Tx Underrun 40 12 Tx Overflow 40 12 Rx Overflow 40 12 Slot Mismatch 40 12 CRC Errors 20 12 Packet Size Errors 20 12 In addition to the above-mentioned errors, if the system loses communication with a RadioBlade transceiver or is unable to read the EEPROM from the blade, then that blade is put into an error state and if a standby blade is available it will switch over automatically. 7.6.1 RadioBlade Locking Policy The RadioBlade locking policy defines the actions taken by the system when a determination is made that a RadioBlade transceiver should no longer be allowed to remain active. This could be the result of an alarm, insertion, removal or intervention (the user specifically locking the RadioBlade transceiver). In general, the policy is that if a blade is taken out of service and a standby RadioBlade transceiver is available, then the standby RadioBlade transceiver will go into service. If no standby RadioBlade transceiver is available then the associated BR(s) will be locked. (For the Multi-Channel RadioBlade transceiver, the locking event locks all carriers.) The RadioBlade locking policy is enabled by default and in effect at all times. 7.6.1.1 Standby Blade A Standby Blade is an extra RadioBlade transceiver that is installed in the system but does not have a configured BR with which to register. To setup Standby Blades, make sure that there are more RadioBlade transceivers for each RBS Group than Base Radios configured in the iDEN configuration page.

MC-Series High-Power System Scheduled and Unscheduled Maintenance 998--01 Rev X1 RadioFrame Networks, Inc. CONFIDENTIAL AND PROPRIETARY 83 In all the conditions described below, if RadioBlade transceivers are present in the system that are in the hot-standby state, then locking the RadioBlade transceiver (due to alarms, removal of a RadioBlade transceiver or administratively locking RadioBlade transceivers) will result in the hot Standby Blade transceiver being assigned to the BR that de-registered the locked RadioBlade transceiver. 7.6.1.2 Locking Policy for RadioBlade Transceiver with Errors If the RadioBlade transceiver generates enough faults such that it crosses the Bounce and Duration threshold for that particular error, an alarm will be generated. The RadioBlade controller then notifies the associated BR, which then locks the RadioBlade transceiver. This will result in disabling the BR. If there is a faulty RadioBlade transceiver in the system (generating error alarms), it is prevented from coming up after a commanded reset/system reset, but the operator could manually unlock the RadioBlade transceiver, at which point the RadioBlade transceiver would be assigned to a BR. (This would not prevent the system from locking it again if an excessive error condition recurs). 7.6.1.3 Removal of RadioBlade Transceiver When a RadioBlade transceiver is physically removed, an event is generated in the System Manager Event Log notifying the user about the RadioBlade transceiver removal. The RadioBlade controller will then de-register the RadioBlade transceiver from the BR(s), which will result in locking the BR(s). A RadioBlade transceiver Insert event is generated when the RadioBlade transceiver is inserted into the system. 7.6.1.4 Administrative Locking of a RadioBlade Transceiver By definition, administrative locking of a RadioBlade transceiver is in effect if the RadioBlade transceiver lock icon on the RadioBlade Transceiver Status page is changed to “locked”. The Multi-Channel RadioBlade transceiver is treated as a unit (single RBID) with respect to administrative locking. The following rules apply to locking a RadioBlade transceiver. • The BR(s) associated with the administratively locked RadioBlade transceiver will go into a Disabled state. Only that RadioBlade transceiver will lock, and its icon will change to “locked”. • If an administratively locked RadioBlade transceiver is replaced, the new RadioBlade transceiver will be considered unlocked upon insertion. (Administrative locking applies to a particular RadioBlade transceiver and not to a particular RBS Slot). • Upon unlocking an administratively locked RadioBlade transceiver, the BR that was previously disabled due to the locked state will go into the enabled state. The lock policy will be preserved through a system reset. Locking of the RadioBlade transceiver will also be preserved through a system reset. Locking of RadioBlade transceivers in the disabled state will not be preserved through a system reset. However, after a system reset, those blades that were originally in the disabled state due to the
