UMC 1000A Spread Spectrum Radio Supplement December, 1997 The UMC 1000 Spread Spectrum Radio (SSR) System 2. With the introduction of AFC‘s SSR transceiver (SSR—XCVR), spread spectrum radio technology has come into its own in the telephony world. Highly effective in deploymentsituations that are physically impossible or financially impractical for other transport media, spread spectrum radio transmission provides highly reliable voice and data transmission for a fraction of the investment required for traditional telephony deployment. The UMC SSR—XCVR is a digital microwave radio transceiver that uses spread spec— trum technology for license—free digital communications links. It operates along a line—of—sight propagation path at a license—free ISM (Industrial, Scientific and Medi— cal) frequency band of 2.400 to 2.483 GHz, or at an optional ISM band of 5.725 to 5.850 GHz. Spread Spectrum Radio 4. Spread spectrum radio transmission technology has been used for decades by the military for communication of important data because it is hard for an enemy to detect, intercept or jam the signal. These same features make SSR ideal for commer— cial telephony applications. Commercial applications for SSR technology include wireless LANs, digital dis— patch, digital cellular telephony, internet connections, radio modem devices and more. Spread spectrum systems are classified into two general groups: frequency hopping and direct sequence. Some systems employ a combination of both techniques. The AFC SSR uses the Direct Sequence Spread Spectrum (DSSS) technique. DSSS processing spreads the information signal over a large bandwidth, resulting in a lower power spectral density (PSD). The lower PSD of the transmitted carrier reduces the chance of interfering with other communication systems. The sequence used to spread the carrier is often referred to as a Pseudo Noise (PN) sequence due to its pseudo—random nature. The DSSS receiver uses the same PN sequence to establish a correlation between the received signal and the expected PN pattern. Undesired signals that fall within the DSSS receiver bandwidth are not corre— lated with the receiver, and therefore, are rejected. This effect is useful in overcoming spurious interference. The extent to which a DSSS carrier can withstand interference is called the jamming margin. The jamming margin makes reliable radio communica— tion possible in hostile environments. Advanced Fibre Communications, Inc. Proprietary Information Page 4 Notfor use or disclosure except by written agreement with AFC

UMC 1000A December, 1997 Spread Spectrum Radio Supplement At the transmitter, the modulating signal spreads the carrier via a unique PN code. The spread carrier is then de—spread at the receiver using the identical PN code. The key characteristic of spread spectrum communications is that occupied bandwidth for information transmission is much larger than the information bandwidth itself. The SSR—XCVR spreads the information 11 times over the transmission bandwidth. The nature of a spread carrier is such that the transmitted information is retrieved even if the received carrier is not intact. Various propagation and interference phenomena can disrupt the transmission, but the information is still extracted error free. The sus— ceptibility to disruption is improved by higher spreading ratios; the trade—off is wider occupied bandwidth. 10. The reliability of a radio system is directly related to the system‘s fade margin. The fade margin is defined as the difference between the received signal strength and the minimum required signal strength to maintain specified performance criteria. Higher fade margins result in higher reliability. The other variables included in reliability calculations are propagation factors. Examples of such factors are climate and ter— rain. Humidity and precipitation result in lower reliability figures. Mountainous ter— rain, surprisingly, results in higher reliability as opposed to smooth terrain surfaces due to wave reflections. The UMC SSR System 11. The UMC SSR system is easy to deploy, delivers great cost savings over other trans— port media, and requires little maintenance. It is ideal for transmission over rough terrain or water where other transport media are ineffective or cost—prohibitive. The sophisticated and straightforward craft interface simplifies provisioning, turn—up and test. 12. The SSR transceiver is a modular plug—in printed circuit board installed at both the LET and RST ends in any of the multi—purpose slots in the UMC channel bank. 13. The UMC SSR transceiver provides a 30 DSO interface over a line—of—sight micro— wave link in the ISM frequency band of 2.400 — 2.483 GHz. An optional interface allows transmission over a 5.725 — 5.850 GHz frequency band. The link carries the data at 2.048 Mbps. Under certain conditions, the system can manage two 30 DSO interfaces on the same microwave span. 14. The SSR system operates along a line—of—sight link only. Any type of obstruction in the radio propagation path will interfere with the operation of the system. The SSR span lengths vary depending on the specific application. Short spans of a few hun— dred yards are easily implemented with high fade margins. Long span lengths, how— ever, are limited to the system reliability tolerance. Larger size antennas enable the SSR system to operate across spans of over 30 kilometers. Favorable propagation environments extend the span to over 40 kilometers with high reliability.

UMC 1000A Spread Spectrum Radio Supplement December, 1997 15. Since system performance is dependent upon numerous propagation factors unique to the physical application environment, each installation site must be engineered for optimum performance and reliability. For referrals to a qualified site engineer, call AFC Applications Engineering at (707) 794—7500. System Components 16. Each node of the typical UMC SSR system comprises only a few components: * UMC Channel Bank Assembly (CBA) with common control units * SSR—XCVR modular transceiver * Cable Adapter Assembly (CAA) * Antenna Interface Module (AIM), containing the Low Noise Amplifier (LNA) and diplexor * Optional Spread Spectrum Interface Assembly (SSIA) containing the transverter (necessary for the 5.7GHz band) * Antenna receive and transmit cables * Antenna dish and mounting unit 17. This section provides more detail on the system components. « Channel Bank Assembly: The conventional 26—slot UMC CBA rack—mount card cage, or the 26—slot broadband card cage, or the 14—slot RSC/48 card cage, houses common control units such as the CPU, power supply unit (PSU), expansion link unit (ELU) and expansion bank control (EBC) if more than one CBA is present, and optional metallic test unit (MTU). The CBA also houses the SSR and other transceiver units, along with any other channel units needed according to the overall system configuration. Conventional copper or fiber can be deployed in conjunction with the SSR link, and several links can be established. Conventional UMC architecture supports both daisy—chained and star configurations.

UMC 1000A December, 1997 Spread Spectrum Radio Supplement * SSR—XCVR: The UMC SSR transceiver provides a 30 DSO interface over a line—of— sight microwave link in the ISM (Industrial, Scientific and Medical) frequency band of 2.400 to 2.483 GHz. The SSR—XCVR is a modular UMC plug—in printed circuit board that contains both transmit and receive functions. Both the local and remote terminals must be equipped with the SSR—XCVR to establish a full duplex span over a micro— wave radio link. The SSR—XCVR is completely transparent in the operation of the UMC; the required allocation of channels is handled with local microprocessors that establish the required DSOs within the architecture of the UMC backplane. * Optional Spread Spectrum Interface Assembly (SSIA): The SSIA contains the transverter module that is required when the 5.7 GHz band is used as the trans— ceiver frequency spectrum. The transverter is a frequency shifting module. Currently there is a 2.4 GHz to 5.7 GHz transverter module available. The transverter works in both directions for frequency translation. The transverter module is powered from —48Vde fur— nished within the UMC enclosure. * Cable Adaptor Assembly (CAA): The CAA is a rack—mounted support bracket for cabling pass—through termination. Up to four pairs of cables can be mounted and retained on the CAA. The CAA acts as a stress relief for the heavy and bulky antenna cables that may come from the AIM module. The CAA has SMA—to—N bulkhead—style connectors. * Antenna Interface Module (AIM): The AIM acts as the mounting for the LNA (Low Noise Amplifier), diplexor and surge suppressor. The LNA is used to amplify the received signal from the antenna to the SSR—XCVR, The diplexoris a specialized dualfilter that allows the transmitted signal and the received signal to be combined into a single cable between the AIM and the antenna. * Antenna cables: The cables that connect the antenna to the SSR—XCVR, AIM and optional SSIA can be of various lengths, depending on factors at the site such as the beight of the tower, signal link budget, etc. All cables are heavy—duty, indus— trialized, weather—proofed and terminate in rugged "N" or "SMA" type connec— tors.

UMC 1000A Spread Spectrum Radio Supplement December, 1997 Transmit and receive cables connect the SSR—XCVR to the CAA; between the SSR—XCVR and the SSIA there is an additionaltiming cable. * Antenna; The antenna size is determined by the span and power requirements of the site. Sometimes these are limited by radio regulatory commissions and hence only certain options are available. In general, increased span distance requires a larger antenna. However, other considerations are the gain of the antenna selected, the mounting of the antenna and the cabling to the antenna. Frequency considerations also play a role. The parabolic reflector focuses the signal onto the antenna feed module. This feed module is selective to the frequencies used in the system. It is important to use the correct feed module receiving the desired frequency band. For informa— tion on obtaining the feed module, contact AFC Applications Engineering at 707—793—8700 for a referral. The tower type and size is determined by the site and path and must be suffi— ciently high to allow an unobstructed line—of—sight path to the other antenna of the link. In some cases no tower is needed and the antenna may be mounted on the side of a tall building. In other cases an existing tower structure may be used. An antenna mount attaches the antenna to the mounting structure. The mount must allow for at least a 10° variation in the angular positioning of the X and Y directions of the antenna to permit proper alignment. This mount must also con— sider the attachment of the necessary cables, lightning protectors and aviation beacons. Power to the antenna is under UMC system control and is calculated and regu— lated on a site—by—site basis. Antenna size and gain will determine the radiated power, Regulatory commissions may restrict the regional radiated power limits. Advanced Fibre Communications, Inc.

UMC 1000A Spread Spectrum Radio Supplement December, 1997 Installing the SSR Transport System 18. Installing AFC‘s SSR transport system can be broken down into four basic steps: * Selecting the frequency band the SSR—XCVRs will utilize * Choosing and preparing the installation site * Selecting and installing the proper antenna (size and feed type) * Installing the Antenna Interface Module (AIM), Cable Adaptor Assembly (CAA), Spread Spectrum Interface Assembly (SSIA) if required and the neces— sary cables Note: Since system performance is dependent upon numerous propagation factors unique to the physical application environment, each installation site must be engineered for optimum performance and reliability. 19. The operator of the spread spectrum intentional radiator or, if the equipment is pro— fessionally installed, the installer is responsible for ensuring that the system is used exclusively for fixed, point—to—point operations. Selecting the SSR—XCVR frequency band 20. Currently, there are two frequency bands available for SSR—XCVR transport: * The ISM (Industrial, Scientific and Medical) band of 2.400 to 2.483 GHz * An optional ISM frequency band of 5.725 to 5.850 GHz 21. In each of these two frequency bands, the user may select a primary and a protection frequency. There is no priority assigned to one of these frequencies over the other. Once the SSR—XCVR is enabled, the system will begin searching to create a link on either of those two frequencies. The system will begin operation on whichever of the two frequencies it synes onto first. 22. The alternate frequency, either primary or protection, will not be used unless other interference occurs. In that case, the system again begins searching on the alternate frequency, shifting back and forth between the primary and protection, until a link is established again. 23. In some cases, the user may decide not to assign a protection frequency for an SSR system, using only the primary, because of the proximity of other SSR systems or other factors. The frequency planning process will determine such considerations. Advanced Fibre Communications, Inc. Proprietary Information Page 10 Notfor use or disclosure except by written agreement with AFC

UMC 1000A December, 1997 Spread Spectrum Radio Supplement 24. Selecting the proper frequency band for a particular site will depend on several fac— tors, including: * Regulations restricting the use of either of the two bands mentioned above * Span distance between nodes coupled with local output power restrictions * Antenna size restrictions based on existing structure or building limitations Note: Since system performance is dependent upon numerous propagation factors unique to the physical application environment, each installation site must be engineered for optimum performance and reliability. Choosing and preparing the installation site 25. Due to SSR technology‘s line—of—sight requirements, the strategic placement of each SSR node is of utmost importance. Areas identified as potential installation sites should be clear of obstructions such as existing or planned buildings, trees and hills. Note: The use of existing buildings or towers should be considered when choosing an installation site as this may reduce construction costs and installation time. Note: Since system performance is dependent upon numerous propagation factors unique to the physical application environment, each installation site must be engineered for optimum performance and reliability. Selecting and installing the proper antenna (including size and feed type) 26. Selecting the optimal antenna size is determined by calculating the span between nodes and accounting for power requiremenits. Radio regulatory commissions may limit the available antenna options. For referral to antenna vendors, contact AFC Applications Engineering at 707—794—7500, 27. Generally, increasing the span distance increases the size of the required antenna. However, other considerations such as antenna gain, mounting and cabling restric— tions, and polarization must be specified. 28. Selecting the proper antenna feed type is also important. The antenna feed module (located on the antenna‘s focal point) is selective for frequencies used in the system. Note: The correct feed module for the deployment spectrum must be used. Note: Because antenna selection and installation is dependent upon so many fac— tors unique to each installation site and use, each installation site must be engineered for optimum performance and reliability.

UMC 1000A Spread Spectrum Radio Supplement December, 1997 Installing the Antenna Interface Module (AIM), Cable Adapter Assembly (CAA), Spread Spectrum Interface Assembly (SSIA) if required and the necessary cables 29. The AIM is the mounting for the Low Noise Amplifier (LNA) and diplexor. Various factors such as the height of the antenna, system power limitations and local radio regulations may require the AIM to be installed anywhere between the antenna and the CAA, 30. Installation of the AIM should be performed on a site—by—site basis only. Figure A—1 shows a typical SSR installation including the location of the AIM. Antenna Duplexer >i4—> AIM——»| — LNA 3 mc CAA UMC CBA > —»1 L, T #= N—Type | Connector SSR—XCVR Transverter/SSIA Figure A—1. Typical SSR Installation at 5.7 GHz 31. The CAA is a rack—mounted support bracket for cabling pass—through termination. The CAA provides stress relief for the heavy and bulky antenna cables coming from the AIM. 32. As with the AIM, installing the CAA should be performed on a site—by—site basis only. Figure A—1 shows a typical installation including the location of the AIM. 33. When the 5.7 GHz frequency spectrum is utilized, a special transverter is required. Currently, there is a 2.4 GHz to 5.7 GHz transverter module available. This trans— verter is a frequency translating module thattranslates the frequency in both direc— tions (2.4 GHz to 5.7 GHz for transmission and 5.7 GHz to 2.4 GHz for reception). 34. The transverter is retained in the Spread Spectrum Interface Assembly (SSIA). The SSIA and transverter module are installed between the UMC 1000 CBA and the CAA. Figure A—1 shows a typical installation including the location of the SSIA. Advanced Fibre Communications, Inc.

UMC 1000A December, 1997 Spread Spectrum Radio Supplement 35. The cables that connect to the antenna, AIM, and optional SSIA can be of various lengths that are a function of the site, the height of the antenna, signal link budget and other factors. 36. All exterior cables (including the antenna feed, antenna transmit and antenna receive) are heavy—duty industrial, weather—proof and terminate in rugged "N" type connec— tors. Note: Because AIM, CAA, transverter and cable installation is dependent upon many factors unique to the physical application environment, each installa— tion site must be engineered for optimum performance and reliability.

UMC 1000A December, 1997 Spread Spectrum Radio Supplement Transceiver {Enabled]: Enabled 54. This setting is used to specify whether a SSR span can be used in a network. If the SSR can be used, type "Enabled" and press {ENTER}. If the SSR is not to be used in the network, type "Disabled" and press {ENTER } to disable the SSR transceiver. 55. If the 5.7 GHz (5735 to 5840 MHz) frequency range is desired, a transverter fre— quency must be entered when prompted: Transverter Frequency [None): 56. This setting is used to specify the frequency shift provided by an external transverter. The transverter frequency setting is limited to the 3326 to 3366 MHz range (select— able in 2 MHz steps). If the transverter frequency value "None" is selected, no fre— quency shift will take place. The standard 2.4 GHz frequency range (2410 to 2473 MHz) is available. 57. When all settings for the SSR transceiver have been entered, the system prompts the user asking if the modified settings are to take effect. Effect Changes? [Yes)]: 58. To use the new settings, type "Yes" and press {ENTER}. If the settings are not cor— rect, type "No" and press {ENTER}. A "No" response causes the system to leave the settings for this SSR transceiver at their previous values and go on to the next card. If corrections need to be made, repeat the Modify Transceiver Settings command. 59. When all cards in the specified range have been found and all SSR transceiver set— tings have been established, the system returns to the Transceiver Settings Menu prompt. The List Alarm Thresholds Command 60. The List Alarm Thresholds command allows the user to list all BER thresholds that are currently set for all of the different transceiver cards in the system. The alarm information is generated by the transmission card as it constantly monitors both data bits and Cyclic Redundancy Check (CRC) violations. The collected data is used to calculate a Bit Error Rate. The BER is calculated for each end of the transmission span on the received data. The system operator may specify the Bit Error Rate where specific alarms are to be reported. Two BER alarms are currently supported, the BER Red alarm and the BER Maintenance alarm. The BER Red alarm indicates that the facility can no longer carry traffic. The default value for this alarm is 10%°. When the system detects a BER at this threshold, the facility is removed from service. If a redundant facility is available, service is concentrated onto it. Otherwise, trunk con— ditioning is initfated. The BER Red alarm is a major alarm if no protection is avail— able; it is a minor alarm if redundant facilities are available for concentration. The Advanced Fibre Communications, Inc. Proprietary Information Notfor use or disclosure except by written agreement with AFC Page 21

UMC 1000A Spread Spectrum Radio Supplement December, 1997 BER Maintenance alarm indicates that the facility service is degraded. The BER Maintenance default threshold is 10°° for fiber, 10for T1, and 10°° for RF (includ— ing SSR). The BER Maintenance alarm is a minor alarm. 61. To list the current BER threshold settings, type {3} at the prompt and press {ENTER}. The system will display a list of the current BER threshold settings on the screen. Figure A—5 shows a sample listing using the List BER Thresholds command. This report may also be printed on a printer.

Sample List BER Threshold Screen The Modify Alarm Thresholds Command 62. The Modify Alarm Thresholds command allows the user to change the BER thresh— old settings for a specific transmission medium. To modify the BER thresholds, type {4} at the Transceiver Provisioning Menu prompt and press {ENTER}. The system then prompts the user for the type of facility to be modified. Enter Facility Type [Fiber}]: 63. Enter the "RF" facility type at the prompt and press {ENTER}. If the {ENTER} key is pressed without specifying the "RF" facility type, the system uses the default value, "Fiber". Press the {[} or {}} keys at the system prompt to scroll through the system options. Press {ENTER} when the desired facility is displayed at the prompt. 64. After entering the "RF" facility type, the system prompts the user for the new BER thresholds to be used for the specified facility.

The first alarm threshold is the BER — Red Alarm. This threshold sets the Bit Error Rate at which a Major or Critical alarm is generated. This alarm indicates that the system transmission is too poor to carry traffic. For example, to trigger a BER Red Alarm when the BER reaches 1 x 10°°, enter the "3" at the BER — Red Alarm prompt. BER — Red Alarm [3]: 66. If the number entered is not valid, the system will display an error message identify— ing the error. Correct the error by entering a valid value at the prompt and pressing {ENTER}. When a valid value has been entered for the BER — Red Alarm, the sys— tem prompts for the alarm threshold value for the BER — Maintenance Alarm. BER — Maintenance Alarm [8]: 67. At the prompt, enter the desired BER alarm threshold that will trigger a maintenance alarm and press {ENTER}. The {{[} or {]} keys may be used to step through the available options. This value indicates that the system is experiencing sufficient errors in transmission that the system is in danger of failure. If an invalid value is entered, the system will display an error message identifying the problem. When a valid value is entered, the system will set the BER thresholds and display the mes— sage "System Thresholds Updated" and return to the Transceiver Setting Menu. 68. From any menu in the system, the "A" command is available. To list all alarms, type {A} at the Transceiver Setting Menu prompt and press {ENTER}. 69. To return to the Provisioning Menu, type {B} at the Transceiver Setting Menu prompt and press {ENTER}. 70. To return to the Main Menu, type {*} at the menu prompt and press {ENTER}. 71.
