This preparation will have been covered by a site survey conducted by Airspan Networks or by a survey form completed by the customer. The survey will include a site plan of the facility identifying the floor layout, power outlets, distribution boxes, and cabling runways. A sketch showing the rack support arrangements showing the exact positions of the mounting points on the rack with dimensions, and typical overhead ironwork provision should be included. Inspect the site, and particularly the equipment room, before unloading or unpacking the equipment to ensure the following:
Installation 5  Air conditioning is installed and funtional (if required to maintain room environment).  Adequate grounding is provided.  Access to the equipment room will be adequate for normal handling and movement.  Adequate lighting is available for carrying out the installation. Any non compliance with acceptable standards should be bought to the customers attention and resolved before proceeding with the installation. Power Availability From the site survey, confirm the location of the fuse position for the negative battery supply and the return point required for each rack. Also locate the fuse position for the alarm unit power supply. Site Earth Confirm the position of the grounding point using the site survey. Flooring Ensure that flooring is substantial enough to support the rack and can provide a secure fixing. Cable Trays Verify that cable trays are installed to provide routing to the proper destinations and are of adequate strength Delivery Inspection Upon taking delivery of the equipment consignment, check that the consignment agrees in all particulars with the consignment delivery documentation (number of boxes, descriptions, and the contents of boxes, etc.).

Installation 13 Rack Installation Positioning and Securing Racks Installing Rack in a Suite From the site survey, confirm the position of the CT Rack(s). If the racks are to be positioned in a suite, metalwork will be required to secure it to the overhead structure. Either a proprietary system or fabricated steelwork will be required - see site survey. Manoeuvre the racks into position. Securing Rack Base Using the base of the rack as a template, mark the floor locating positions through the cutouts in the Rack Frame. Using a 13mm diameter drill bit, drill four holes to a depth of approximately 25mm. Position the rack over the four holes and screw the four (supplied) M12 screws through washers to secure the rack base. If the rack is cabled from under the floor the access holes are required through the floor beneath the rack base. Securing Rack Base Warning: These screws are provided as locating pins only and must be used in conjunction with the overhead steelwork and not as the only method for securing the rack. Temporarily secure the rack to adjacent racks or steelwork until the overhead support is in place. Securing the rack using overhead Ironwork Assemble the overhead steelwork as required and secure the rack to the overhead structure using suitable fixings in compliance with local requirements. Remove all burrs and sharp edges.
Printed Documentation 14 Typical Overhead Ironwork Support Note: In installations where threaded droprods in excess of 500mm are employed it may be necessary to provide additional support bars to ensure rigidity of the support structure. Securing a Rack to a Wall If the rack is to be positioned against a wall, attach two right-angled wall brackets to the top of the rack and finger tighten with the provided M12 screws. Manoeuvre the racks into position against the wall. Join the racks together with 12mm nuts and bolts placed through the holes at the top and bottom of the side panels and mark the wall through the holes in the top brackets. Securing Rack to a Wall Using an 11mm. drill bit, drill holes in the wall to a depth of 75mm and fit masonry plugs. Fix the hex head screws through the brackets and finger tighten. Check that the rack is in the correct position and tighten all fixings. Attention should be paid to the fabric of the wall. Where possible, drill directly into the brick and not into mortar. With panelled or partitioned walls, instruction should be taken locally as to how the rack is to be secured. See site survey. Follow the procedure for the rack base as described above.
Installation 15 DC Power and Alarm Cabling Rack Earthing Using the site survey, locate the building central [safety] grounding point. Run an earth cable rated at 30A to each rack and connect it to the centre earth stud located at the top or at the side of the rack. (only one external earth per rack) See illustrations below. These points are labelled with the IEC Earth symbol. Rack earthing at top Rack earthing at base Other external safety earth connections must not be made to the rack.
Printed Documentation 16 Terminate the battery feed and return cables at the isolator/fuse positions, and ensure that the AC rack is isolated until the commencement of commissioning tests. DC Power The cables for the negative DC battery feeds, the 0V returns and the Rack Ground are detailed in. Should local requirements specify otherwise, it is acceptable for cables of other colours to be used, however, under no circumstances should the cable sizes be less than that specified in. The length of the cable supplied will be detailed in the site survey. Separate DC sources are desirable for maximum protection. Function Colour Min. Cable Size Negative Battery Feed -36V to -60V DC Blue 10 AWG; 6.0mm2 Zero Volt Positive Battery Return Black 10 AWG; 6.0mm2 Rack Ground Green/Yellow 8AWG; 10.0mm2 DC Power Cables. This equipment requires a negative Supply. Ensure that the +ve volt line is connected to ground or that the supply is floating. The –ve battery feed should not be connected to ground or zero volts under any circumstances. The maximum DC input should not exceed 60 Volts. Voltages in excess of this are considered hazardous. Note 1: Do not insert fuses until instructed to do so in the commissioning stage of installation. Note 2: If the equipment is installed according to EN 60950 §1.7.9, there should be available a single disconnect device that isolates the whole equipment., A double-pole external isolating switch should be provided to isolate the two supplies and should be wall mounted in the locale of the rack. A label should be included on the unit to direct the user to use the external isolator for isolation. The Access Concentrator and Central Terminal Shelves are designed to operate from a -48V DC supply. In installations where the nominal supply voltage is +24V DC a DC to DC converter is needed to provide the -48V supply see the schematic diagram below. The DC to DC converter must be rated at 20 amps or greater at -48V DC
Installation 17 Power Supply Configurations Three alternative methods are possible to connect the DC supply to the rack.  Secure Supply: This is the preferred method as it provides DC from different sources giving greater resilience of supply than the other methods. (see diagram above and note 2 below) From each Distribution Boards (DB) run and tie in a negative battery feed and a zero volt return to a Dual Pole Isolating switch and then from the isolating switch to the AC/CT rack installed. These supplies should be rated at 30A. Power cables must be run and tied separate from signal cables.
Printed Documentation 18  Dual Supply: Both feeds are fed from the same Distribution Boards (DB) and separately fused so that in the event of one fuse failing the rack is supplied via the other fuse. Run and tie in two negative battery feeds and a two zero volt returns from the Distribution Board to a Dual Pole Isolating switch and then from the isolating switch to the to the AC/CT rack installed. These supplies should be rated at 30A. Power cables must be run and tied separate from signal cables. (see diagram above and note 2 below).  Single Supply: Is the least preferred option as a blown fuse causes the total loss of supply to the rack but because there is only one supply the fuse can act as an isolation point and there is no need for a separate isolation switch as required on the other options. Run and tie in a negative battery feed and a zero volt return from the Distribution Boards to the AC/CT rack installed. The two inputs to the Combiner Shelf/Fuse and Alarm Panel should be looped together as shown in the diagram above. This ensures that the alarms on the PSU are extinguished when a supply is present. From the site survey confirm the location of the isolator for the negative battery feed points; then ensure that the supply is isolated. If the location is remote from the AC Rack, take appropriate action to ensure that the supply is not inadvertently reconnected. This may include locking OFF an isolator, removing fuses and ensuring that replacement fuses are not easily installed. Provide a label at the AC Rack to indicate the location of the isolator or fuse positions mentioned above. To provide security of supply two separate Distribution Boards (DB) should be used to supply DC to each rack (see note 2 below) Run and tie in a negative battery feed and a zero volt return to the AC/CT rack installed from the DB. Run and tie in a second negative battery feed and a zero volt returns to the AC/CT rack installed from a second DB, if a second distribution board is available. If only one source of supply is available the both supplies may be run from the same DB These supplies should be rated at 30A. Power cables must be run and tied separate from signal cables. DC Cabling Central Terminal Modem Rack/Integrated Basestation Run the DC cables through the top right hand side of the rack, loosen the screws on the Combiner Shelf and slide the screen to the right. Place the DC cables behind the screening and though to the connection block at the lower right of the Combiner Shelf. Return the screen to its original position. Re-tighten the Combiner shelf screws. Trim cables and strip 7mm to insert into the termination block. Terminate the cables on the Combiner Shelf at the appropriate connection points. The negative supplies go to Termination Block 2 & 4. The positive battery returns go to 1 & 3. DC Termination on The Combiner Shelf. DC Termination on Fuse and Alarm Panel (AS4000 Access Concentrator and AS4000 Expansion Rack) Run the DC cables through the top left hand side of the rack, into the fuse and alarm panel.
Installation 19 Remove clear plastic cover protecting the DC input terminals. Trim cables and strip 7mm. Crimp a spade terminal or terminal ring onto the wire and attach to terminals inside the Fuse and Alarm panel at the appropriate connection points. The negative supplies go to Termination Block 1 & 4. The positive battery returns go to 2 & 5. Replace clear plastic cover protecting the DC input terminals. DC Termination on Fuse and Alarm Panel.

Installation 33 PTU to Host Cabling RJ45 to DB25 Adaptor To connect the 100baseT cable to the AC Shelf interface panel a RJ45 to DB25 adaptor must be fitted. Fit the RJ45 to DB25 adaptor and screw to the backplane. The RJ45 to DB25 adaptor currently must be connected onto the lower of the two 25-way AC connectors allocated to each slot (even though the activity lights work if connected to the top). Patch Cable A standard Cat 5 Ethernet patch cable with 8-way RJ45 plugs at each end has all pins connected straight through. The Tx and Rx pairs are pins 1&2 and 3&6. With plug towards you, cable away from you, pins on the top, pin 1 is on your right. Clearly Tx at one end must talk to Rx at the other. A Hub (and Router) Ethernet port will have a built in crossover, often denoted by a ‘X’ printed on the box, so a PC to a Hub uses a straight through standard patch cable, and so does a Router to the PTU. To connect a PC to PC or a PC to PTU (for demo, tests, etc.), use a crossover cable, with Pin 1 to Pin 3 and Pin 2 to Pin 6.

AS4020 is flexible in its deployment, although is must remain within a couple of meters of the radio sub-system. Initially the AS4020 CT shelf is fitted within the AS4000 CT rack with the Radio sub-system, and optionally alongside up to two AS4000 CT shelves. Alternatively a half-height AS4000 CT rack can fit four AS4020 shelves and a radio sub-system. All connections to the AS4020 shelf are through the front of the unit, except DC power, which is fed from the RF combiner shelf to the rear of the unit. the illustration below shows a the interfaces available on the front of the AS4020 CT shelf. All connections are made to the front panel with the exception of the power connection at the left hand side of the shelf. All cables should enter via the cable tray above the shelf. Cable entry to the main panel is via the left hand opening and via the right hand opening to the option panel as this avoids the possibility of cables obscuring the menu. The AS4020 CT shelf is cooled using fans that are hot-pluggable in the event of failure. An AS4020 CT shelf can only be installed in a weather-protected location. The AS4020 CT shelf provides a terminal connection for initial configuration of the Ethernet ports, a method for commissioning the system, and menus for basic systems diagnostics. In addition to the terminal interface, AS4020 contains an LCD screen to provide alarm details and limited status information. Full configuration of AS4020 is via the management system, which can be a local Ethernet connection, or via the network Ethernet interface. The AS4020 CT shelf provides the switching functionality of the system, as well as managing radio access on both the uplink and downlink. The shelf is also responsible for the radio interface architecture, namely BDM, dynamic modulation, and RTS/CTS signalling. When adding shelves to an existing AS4000 system use the following diagrams to determine the points to connect the radio port and combiner monitor connections. o Adding one AS4020 shelf o Adding two AS4020 shelves o Adding three AS4020 shelves o Adding four AS4020 shelves o Adding Two AS4020 Shelves to an existing Two AS4000 shelf rack Installing the Voice Option Board Units are shipped with the option board installed if specified, but options boards may be added to existing shelves.

91 Setup and Test System Testing This section sets up the parameters for the system and the connection to Netspan Refer to the Netspan, document no. 605-0000-509 for the detailed configuration and set up procedures of Netspan and the AS4020 System. General The following procedures need to be carried out in order to verify the functionality and operation of all cards fitted into the Central Terminal prior to placing the AS4000/4020 system into service. It is preferable to connect the As4000/AS4020 to a ISP when commissioning. This allows the CT to be connected and test calls made over the system during the commissioning process. If during testing, a fault occurs preventing the continuation of the test, the faulty module or card should be replaced and the test repeated for the new card module and any other tests that are affected by the performance of that card. All results must be entered on the Commissioning Test Result Sheets (Copies are included in this manual and should be printed as required). Test forms should be photocopied as needed, ensure that sufficient copies of all sheets are available prior to the commencement of commissioning tests. There are two activities required; a) the network management centre should create the sites and equipment in the database (frequency and PN ),using Netspan b) the field engineer should commission the equipment to the recommended parameters (output power and system receiver sensitivity). Pre-Commissioning at the Network Management Centre For a completely new installation, the NMC administrator should create the sites and equipment racks in each site ( with the frequency, PN etc entered, in preparation of the actual equipment installation and commissioning. When expanding the system with additional CT sites, the administrator should add the extra CT equipment using Netspan. During field commissioning, the field engineer will use a local laptop running copy of STMON to control the test ST.
Printed Documentation 92 AS4000 AC Setup and Test Access Concentrator: Turn-Up and DC measurements Pre-Checks Before commencing the turn-up of the rack check that the serial number and Rev levels of all card have been entered into the test form and that the SC boot chip version is recorded. DO NOT power up or plug any cards fully into their slots at this stage. Router Port Availability. If the Sitespan Server is located at the NMC and connected via a router confirm the IP address for the router at the AC and the port for connection (typically a RJ45 cabled to the AC from the back of the router. Apply a loopback on the designated router port (pins 3 to 6 on an RJ45). Check that the router at the AC can be pinged and the loopback seen from the Sitespan Server PC at the NMC by using a simple communication application as hyper terminal at the COM port intended for Sitespan use. Isolate all E1/T1 cables from the AC by removing the links at the DDF. Disconnect all cards from the backplane by pulling forward in the card guides so that the power will not be applied to the cards when the shelf is switched on. Rack Turn-Up and Measuring Input Voltage (Test 1a) This section describes the procedure for measuring and connecting DC to the rack, checking that the cards have the correct alarm indications on power-up and measuring the PSU output voltages. Unscrew retaining screws on the face of the Fuse and Alarm Panel. Hinge forward the panel and using the DMM measure and record the Exchange DC voltage supply across the input terminals (TB1(-); TB2+;.for Supply 1 and TB4(-); TB5(+) for supply 2). Check that the polarity is correct. Ensure that the voltage measured complies with the site nominal voltage and is within the limits specified on the test results sheet. Test Voltage Record the measured voltage on the test results sheet. 3. Turn-Up AC Shelves: (Tests 1b)
Setup and Test 93 Place one PSU in the shelf . Switch the Rack ON by placing one breaker on. The two breakers duplicate power to each shelf and the shelves will still function if one power supply fails though the LED indicators on the power supplies will not be on. The PSU should show a green LED and one supply fail LED. Switch on the second breaker and the Red LED should extinguish. Switch off and place the second PSU in the shelf and repeat the process described in the paragraph above. Access Concentrator Shelf PSU Place a SC Card into the shelf to provide a load. Switch both breakers on and measure and record the DC voltage at the o/p of each PSU. Ensure that the voltages measured are within the limit shown below. Record the results in test form.

Printed Documentation 120 Procedure in case of card boot-up failure Procedure in case of card boot-up failure If the cards inserted into the shelf do not boot-up, the top red LED on the card will be either continuously ON or FLASHING. The following steps should be followed: 1. Check cards are properly inserted into the shelf, in the correct positions 2. Reset the SC card using Netspan/Sitespan, under the card view. 3. The cards boot-up. If the cards do not boot-up try and reset the shelf backplane configuration. Download the SetTUinv.txt to the SC. Ensure they are available before continuing. 4. Disconnect Netpan from the shelf containing cards that will not boot-up. 5. Connect the LAT cable to the SC card 6. Send the text files for the correct shelf, one after another using Terminal. 7. Once completed, type the following: TI 118 EA 118:0/119:0 ES 0 8. Wait 2 – 3 minutes for the process to complete. 9. Reset the SC by shorting Pins 2 & 3 10. Wait for 3 minutes: After 3 minutes the Shelf Controller has a green LED ON, and all the other cards have FLASHING red LEDs 11. Re-Connect Netspan /Sitespan 12. The cards on the shelf boot-up. If the cards do not boot-up, then it is likely that one of the cards is faulty. Try replacing one of the cards and starting the procedure again.
Setup and Test 121 Setting RX sensitivity using DACU 2.0-2.3GHz & 3.4-3.6GHz Band (Test 6) If a DACU is not available use Setting RX Sensitivity without DACU Preparation for commissioning at the Central Terminal 1. The DACU should be powered up and allowed to warm up for 30 mins to achieve stability prior to setting the RX sensitivity. For details on setting up the DACU see Connecting the DACU 2. Enter the loss values in the DACU calibration chart for the relevant frequency See chart below. 3. Calculate/determine total path loss and required DACU output power and hence power meter reading. 4. Connect cables and equipment as per diagram below 5. Ensure that the commissioning button is off. This should have been done at the end of the TX Gain set-up but it is prudent to ensure that it has been switched off. Switching off resets the DTU card, reactivates RW14&15 for link acquisition, and sets all RWs in service. Note: The DTU card view shows all of the RW codes, and their current state within the system (i.e. OOS or IS). 6. Create an ST on Netspan. See Netspan Section 7. Configure test ST using AS7020STMON according to modem shelf properties to the correct frequency, PN code and ID number. 8. Allow test ST to acquire link and net enter to “warm” state 9. Using the ST Line List, set loopback mode on both lines to enable 160k high rate operation. 10. Measure the DACU o/p level 11. On Modem Shelf Properties, set RX gain to achieve required ST o/p level as calculated in step 4 for –98dBm receiver sensitivity Adjust the 'RX Gain' by increasing and decreasing the values. 12. Note: To start with, set the RX gain to around 2200. ( if value is reduced power goes UP). The values may be set by typing in a new value or by using the up and down arrows at the side of the box. The ST power changes in steps of approximately 0.7dB and the nearest value to the required value. A single step on the gain value may not produce any change so start with larger values and through a number of iterations home in on the correct setting. Note: Levels are updated only when the OK button is clicked. Check the output power of the DACU, and repeat until the output power matches that in the DACU Calibration Table.
Printed Documentation 122 14. Record results in test results sheet 15. Power off the DACU. 16. Put all RWs back in service. Restoring shelf connections 1. Remove the test equipment and connecting cables. 2. Replace the Shelf covers and the protective cap on the coupler. 3. Do not remove the Sitespan connection at this time. Entering Test values into Netspan The values of the TX Transmit and RX gain must be set into the Netspan at the Network management Centre before the backhaul is connected to the CT, failure to do this results in the TX power and RX sensitivity values being overwritten by the value stored in the Netspan Server. Connecting CT, AC and NMC At this point, ensure the NMC has the site equipment created in the master database and the V5.1 interface activated. It should show an alarm on the E1 connection to the CT shelf. 1. Contact the NMC administrator, and pass the CT shelf Transmit Power and Receiver Level settings to the administrator for updating the master database. Warning: When Netspan is reconnected to the CT the values of the TX and RX levels stored at the NMC will be written to the SC of the modem shelf and Netspan should not be reconnected until the NMC has updated its database with the correct Transmit and receive level settings. 2. The CT shelf connected to the LAPTOP should be in ‘UNCONNECTED’ state. This is because the shelf is expected to get its data from the remote management system. 3. Reconnect the E1/T1 links to the CTUs/DTUs. 4. At the AC Connect Netspan backhaul to the NMC. If using a router fit RS232 9 way to Async RJ45 adapter to the Netspan port used to backhaul to the server. Connect Sitespan Port 1 (AC Backplane) to Management Network (ports allocated on Cisco Router). 5. Call the NMC and ensure the commissioned shelf is in ‘connected’/ ‘downloading’ state and the E1/t1 alarm on the CTU is cleared. 6. Remove Modem card and check that the alarm is seen in Netspan’

Setup and Test 125 BER Test The BER test is best done from the network management centre but if a management centre backhaul has not yet been established the test may be performed at the AC site and should be set up by connecting Local Netspan/Sitespan to AC Rack, building site locally and create subscriber. Setting up system tests at the Access Concentrator. Create CAS XTU in a spare slot (slot 10 if spare). Create CAS subscriber in Sitespan. Note the timeslot and E1 link used. Fit CAS TU card to the shelf in the configured slot. Fit CAS TU card to the shelf in the configured slot. Setting up Test ST. To perform overall system tests a test ST should be set up. The ST should be located 1 to 5 km from the CT in the centre of the lobe served by the CT. Set up using details to match the RF channel, PN code and ST-ID for the CT sector to be tested. Screen captures of the RF analysis may be taken and pasted into a document for confirmation of the relative signal strengths. Check for the ST to acquire a link and use STMON to ensure that the frequency acquired is that of the CT and not that of an adjacent signal. (see STMON User Guide for details of checking the channel.) For Information on setting up a subscriber terminal see 605-0000-505. Subscriber Terminal installation and commissioning. Measuring BER This process can be carried out at the Access Concentrator and loopback at the ST or if using a Data ST the test may be performed at the L series ST and a loop applied at the Exchange a) Testing at the Access Concentrator Connect BER Tester to E1 in link on the shelf backplane (or Type 43 converter module if used) set above and inject a 64K Pseudo Random Pattern 215-1in the timeslot set above. Put a Loop on the ST from Netspan (In the ST Line List. check the Loopback box and click OK). Note: The loopback is dropped if the link fails or the ST power is cycled To reapply the loopback the loopback tick box should be cleared and the OK button clicked. The loopback should then be re-applied by re-checking the loopback tick box and clicking the OK button.
Printed Documentation 126 The presence of the loopback should be seen at the BER test set. Inject 1 error into the test signal and observe it on the incoming signal to check that errors are detected. Start and stop the test to clear the injected error. Observe the return signal on the T1/E1 out to establish that the link is error free. Run BER test for 1 Hour. On completion of the test remove the loopback (open the Edit DA ST window and click the Loopback box to remove the tick and click OK.) Delete CAS subscriber in Sitespan, and delete CAS XTU. b) Testing at the Subscriber Terminal if L Series SIU used. An alternative method of testing the BER of a link from a CT to an ST is to provide a hard wired loopback on a selected E1/T1 port on a Data XTU Card at the AC site. By using an ST-L128 or ST-l64, 128kbit/s or 64kbit/s data rates may be tested using a BER tester at the ST location. The advantage of this method is that there is no need to have a person at both the AC site and the ST test location Note. A suitable data cable from the BER test set is required. Most BER test sets provide V.35 or X.21 synchronous interface options. Power for a prolonged test may be a problem in field locations . An inverter running from a vehicle 12V supply may be used for tests of up to 1 hour with the ST powered directly from the Vehicle battery Place a physical loop on the E1/T1 at the AC/Exchange. At the AC site: Loopback E1 link on Data XTU card. (loop on shelf backplane or DDF) At the Subscriber Terminal: Connect BER test set to the ST. The presence of the loopback should be seen at the BER test set. Inject 1 error into the test signal and observe it on the incoming signal to check that errors are detected. Start and stop the test to clear the injected error. Observe the return signal on the E1/T1 out to establish that the link is error free. Run BER test for 1 Hour. On completion of the test remove the loopback and re-connect the E1/T1. Delete test data subscriber in Netspan.
Setup and Test 127 Setting the System into Service Checking alarms and connections to Netspan At the AC Test the RS232 disconnect alarm by disconnecting the adapter on Sitespan port I. Pull card and check alarm is visible at NMC. At the NMC set the free list entries. For details on setting free list entries see the Netspan Help File Note System Optimisations to the configuration that improve Net entry time  Ensure that the number of net-entry channels is set to around 6 for a shelf running medium/ large deployments of voice service. The only constraint to be borne in mind is that each channel used for net-entry is not available for traffic, so you need to be careful about not over-provisioning the number of net entry channel if the shelf has a large proportion of data / ISDN STs (which operate in a fixed-assigned mode).  Make certain that any STs that are created in the database before deployment are marked 'out-of-service'. If they're not, on every cycle through the database, the system is trying to net-enter STs that don't exist. Test Call 1. Connect the AC port to Switch (ensure V5.1 link and cards configured). 2. Create a V5.1 DA Subscriber Terminal using Netspan and place the ST in service. Check L3 address unblocked and define phone number. 3. Configure the test ST with the ST Id PN number RF channel and phone number (as set at NMC). 4. Wait for ST to acquire a link (STMON can be used to monitor progress). Check for dialtone. 5. Using a telephone make test call from the test ST over the system. Check for both way transmission and absence of noise and interference. 6. Solicit an incoming call from the NMC or another phone and again check the quality of the call The tests should be completed for all other shelves commissioned on the same base station. At the completion of all tests remove all test cards from the shelf BER Tests See Topic BER Tests Packet Testing See Topic Packet System Testing Site inspection and test card removal When the BER and call tests are completed for all other CT shelves relating to an AC site (may have 1 or more AC shelves) remove all test cards from the AC shelf and delete all test STs from Netspan At the AC and CT sites check all work areas are free of debris i.e. cable off-cuts, braid, dust and packaging and that the site is as found.

At the end of this test a label with the calibrated value should be attached to the coupler. Calibrated attenuators and cables are provided with the DACU for this test. The RX sensitivity is set according to the required CT RX level. It is important to note that the lower the modulation rate the further the geographical spread. For maximum range the AS4020 should use QPSK 1/2. Higher data rates may be achieved using higher orders of modulation but the range will lessen as the modulation rate increase. This level is determined as part of the planning function and takes into consideration the highest modulation rate to be offered and the noise floor predicted in the planning stage. The RX Level is set dependant on the highest operational modulation rate as follows. By undertaking an appropriate level of RF planning the level is optimised in order to balance uplink data rate and system range. Typical levels are shown below for two network configuration scenarios: For networks where only a single RF Channel is operating, or only adjacent + one RF Channels are used (no co or adjacent channel interference), the following CT Rx levels apply: Rx Level (dBm / RW) Modulation Code Rate Below 3GHz Above 3GHz Session ids for LAT TE command in Mode 3 QPSK 1/2 -105 dBm -103dBm 58 or 59 QPSK 3/4 -103 dBm -101dBm 56 or 57 16QAM 1/2 -97 dBm -95dBm 54 or 55 16QAM 3/4 -93 dBm (see note 1) -91dBm 52 or 53 64QAM 3/4 Not supported on the uplink Table 1 Note 1: Note, 16QAM ¾ is only supported on the uplink with up to 7RW codes active. For networks where co or adjacent frequencies are reused to provide “cellular type” network coverage with limited available spectrum (ie. A relatively high level of co and adjacent channel interference), the following CT Rx levels apply: Rx Level (dBm / RW) Modulation Code Rate Below 3GHz Above 3GHz Session ids for LAT TE command in Mode 3 QPSK 1/2 -103 dBm -100dBm 58 or 59 QPSK 3/4 -101 dBm -98dBm 56 or 57 16QAM 1/2 -94 dBm -92dBm 54 or 55 16QAM 3/4 -90 dBm (see note 1) -88dBm 52 or 53 64QAM 3/4 Not supported on the uplink Table 1a 1.

The commissioning procedure described in this document is not restricted to any particular RF channel or PN code. However the user should make sure that both the CT and ST are programmed with identical RF channel and PN code. 9. Using the values of the calibrated attenuators and cable calculate the loss of the attenuators and cable between the DACU and CT as per diagram above: Note the power meter reading. 10. Replace the calibrated attenuators with the coupler and note the power meter reading. If the power meter is more than the previous one then the difference should be added to the sum of the attenuator values and of less it is subtracted from the sum of the attenuator values.

Printed Documentation 148 Packet System Testing Data Tests To pass Ethernet traffic through the AS4020 system, it will be necessary to transfer data between a Server connected to the “Traffic” Ethernet port of the AS4020 CT, and a PC connected to an ST. To test basic functionality, the following throughput speed tests are performed. Test Method & Results: Windows 2000 has a built-in FTP server. This is simple to use, free, and readily available, therefore ideal for setting up a test system to measure AS4020 performance. However this must be installed and activated before use. Also, some suitable test files must be added to the FTP “home directory”, appropriately sized for transferring through the AS4020 system. The FTP command-line client program (also included with Windows 2000) can be used for the transfers. The following tests assume that the FTP server has been set up, test files are available, and that the method of measuring download speed used is as described in Annex A. The modulation scheme in use can be found in the “ST Packet Line Classes” section of the “Global Setup” tree, on the left hand side of the main NetSpan window. The downloads can be automated into a batch file for ease of use – this way the test can be run simply by double-clicking on the batch file, which is more convenient than downloading “by hand”. Equipment Required 2 PC’s with NIC cards enabled. FTP Software (Windows FTP or use DOS prompt) Windows 2000 Server Software Access to the CT over the radio interface from a ST Setting up FTP Server PC 1. Open the Control Panel (Start -> Settings -> Control Panel); 2. Open the “Add/Remove Programs” tool; 3. Click on the “Add/Remove Windows Components” button, found on the left side of the window; 4. Select “Internet Information Services (IIS)” and click on the “Details” button; 5. Make sure that the tick boxes are selected for the following subcomponents : “Common Files”, “File Transfer Protocol (FTP) Server” and “Internet Information Services Snap-In”. It is not necessary to install (or uninstall) any other subcomponents, as they are independent from the FTP Server; 6. Click “OK” on this dialog box, and then click on the “Next >” button. Installation will start, and may take a few minutes to complete. Note: The Installer program will probably need to copy some files from a Windows 2000 Installation CD. If you do not have a CD, it is possible that the installation files will have been previously copied to the hard drive of the PC. If this is the case, search the hard drive for a directory called “i386” and Browse to this directory when prompted for a CD by the installer wizard.If necessary fit NIC card to PC.
Setup and Test 149 Configuration of the FTP Server: The FTP Server needs a home directory – this is where the “root” of the FTP server will be located, and where the files will be downloaded from. These steps detail configuring the directory location, and additionally some other required parameters such as access rights: 1. Right-Click on the “My Computer” icon on the desktop, and choose the option “Manage”. Note: It is possible that the icon will have been renamed, but is usually the blue computer icon positioned at the top-left of the desktop. 2. In the “Computer Management” window that will appear, on the left side is a tree view. Near the bottom of the tree view, expand the “Services and Applications” branch. 3. Under the “Services and Applications” branch, expand the “Internet Information Services” branch. 4. Right-click on the “Default FTP Site” icon that will appear, and choose the “Properties” option. 5. Working through all of the options, set up the FTP site as follows. Note, not all available options are described here - where an option isn’t described below, it is not relevant to this configuration. If you change an option as a result of following this table, you may want to make a note of it so that the PC can be returned to the original settings when you have finished testing: FTP Site Tab: IP Address (All Unassigned) TCP Port 21 Connection Limited to: 10 Connection Timeout 900 Enable Logging Disabled. Do not tick the box. Security Accounts Tab: Allow Anonymous Connections Enabled. Tick this box. Warning: Anonymous FTP access: The above instructions will allow all computers to have Anonymous read, and more importantly write, access to the directory used for the root of the FTP Server. This is clearly not a desirable mode in which to leave the PC when testing is completed. Airspan recommends as a minimum to turn off “write” access, via the “Home Directory” Tab. Home Directory Tab: A directory located on this computer Select this option, as we will be downloading files from this PC. Local Path The drive must be a local hard disk, and have 40Mbyte free space (100Mbyte recommended). Make a note of the path, as it is required in the next section. For convenience you may wish to record it here: Read / Write / Log Visits Enable Read and Write, Disable Log Visits. Warning: Anonymous FTP access: The above instructions will allow all computers to have Anonymous read, and more importantly write, access to the directory used for the root of the FTP Server. This is clearly not a desirable mode in which to leave the PC when testing is completed. Airspan recommends as a minimum to turn off “write” access, via the “Home Directory” Tab.
Printed Documentation 150 Creating suitable download / upload test files: Due to the high transfer rates possible with the AS4020 system, suitably sized test files should be transferred. The recommended test file sizes are of the order of 1Mbyte (uploading) and 10Mbyte (downloading). We must also ensure that any file compression does not result in files appearing to be transferred faster than they actually are. The recommended method for performing the transfer tests (described in the next section) uses an FTP method that transfers files in binary mode, without compression. However, as other utilities may not do this, the test files should not be compressible. To assist with this, Airspan provides a utility for generating uncompressible files of varying sizes. Inside the .zip file embedded below are two files – “filegen.exe” and “generate.bat”. If you do not have an electronic copy of this document, you can request the embedded .zip file by email. Send your request to support@airspan.com Instructions: 1. Unzip the embedded .zip file. The files “filegen.exe” and “generate.bat” should be placed into the FTP Site Directory that was recorded in the previous section. Note: Use Windows Explorer to check that the files are in the correct location. Do not use the “right-click” option to “Extract to folder …\FTP test file generation”, because a new subdirectory will be created and the files placed there. You can use Windows Explorer to move the files to the correct location if you have used this method to extract the files, or have extracted them elsewhere on the hard disk. 2. Defragment the partition of the hard disk which contains the FTP Site Directory: a. Opening Windows Explorer select the Drive letter containing the FTP Site Directory; b. Right-Click on the drive letter and choose “Properties”; c. Select the “Tools” Tab at the top; d. Press the “Defragment Now…” Button; e. When the defrag program opens, press the “Defragment” button. Note: This may take many minutes to run, and may require some disk space to be freed if there is less than 15% free disk space. 3. When the defragmentation is complete, navigate to the FTP Site Directory using Windows Explorer. 4. Double-click on the “generate.bat” file. Note: For information - The “filegen.exe” program takes the command line parameters denoting the filename and size in Kbytes, and creates files containing random data (hence the files cannot be compressed at all, they will grow in size if “zipped”). The “generate.bat” batch file repeatedly calls the “filegen.exe” to create a set of uncompressable files of varying sizes. You may wish to edit this file if you need different file sizes. The batch file will generate the following files: File Name File Size (Bytes) 100K 102,400 200K 204,800 500K 512,000 1M 1,048,576 2M 2,097,152 5M 5,242,880 10M 10,485,760 These numbers follow the binary data store convention of 1KB = 2^10 Bytes, 1MB = 2^20 Bytes. The file generation process will take approximately 30 seconds to complete, depending on the specification of the Server PC.
Setup and Test 151 Using the FTP Client, and automating the transfers: To perform the data transfers, an FTP Client running on a PC connected to an ST will download and upload data files to the FTP Server running on a computer connected to the same network as the Traffic Port of the AS4020. To avoid the influence of other network traffic, all other computers on the network should be disconnected. If this is not possible, disconnect from the network, and connect the FTP Server directly to the Traffic Port of the AS4020 using a crossed Ethernet cable. The Traffic Port should be set to 100Mbit/sec, half-duplex mode. The FTP Server PC’s Ethernet port should be set to “Auto Speed, Auto Duplex”, or alternatively to 100Mbit/sec, half-duplex. It is recommended to use the command-line FTP Client which is included with all versions of windows, as this will already be available on the PC (as it is installed at the same time as the TCP stack) and gives a speed result at the end of the transfer. The FTP Server PC and the FTP Client PC must have IP addresses in the same subnet. If the PCs can “ping” one another, then they will be able to perform FTP transfers between them. Note that when measuring uplink speeds (i.e. in the direction from the ST to the AS4020), it is not necessary to run an FTP Server on the ST. Instead the FTP Client on the PC connected to the ST will perform an FTP upload to the Server. Note: It is possible that an FTP download could be cancelled or aborted part way through (a number of reasons could cause this). If this is the case, the partly transferred file will reside on the hard disk, and will have the correct name but will not have the expected file size. Therefore the file sizes should be checked before any transfers are made. The files can easily be rebuilt simply by running the “generate.bat” batch file described in the previous section. Alternatively, when transferring files, make sure to choose a different destination filename – i.e. when downloading a file called “1M”, save it as “1M_downloaded”. This is described in more detail below. The following instructions for performing the transfers assume that the IP addresses of the Client and Server PC are in the same subnet and can ping one another through the AS4020 system. Create a working directory containing test files: 1. Create a working directory: Make a new directory on a hard drive with at least 40MB free disk space. You can do this with Windows Explorer by selecting the hard drive letter and choosing “File -> New -> Folder”. Rename the folder as appropriate (e.g. “FTPtests”). 2. Copy the “Filegen.exe” and “generate.bat” files into this directory and run the “generate.bat” batch file (this is described in greater detail in the previous section). This will create a set of files which can be used for upload measurements. 3. Performing a manual file transfer: Open a command prompt window. This can be achieved by following the menu “Start -> Programs -> Accessories -> Command Prompt”, or by opening the “run” box (Press the “Windows” keyboard key and the letter “R” simultaneously) and typing in “cmd” and pressing Enter. 4. Navigate to your working directory, for example if the new folder created in step 1 was “C:\FTPtests”, enter the following commands (all commands shown below should have either the “Return” or the “Enter” key pressed after typing them): c: cd \FTPtests The command prompt will show the directory in which you are working. 5. Run the FTP Client and instruct it to connect to the IP address of the FTP Server. For example of your FTP Server IP address is 10.0.60.1, enter: ftp 10.0.60.1
Printed Documentation 152 6. The Server will ask for a username and password. Enter the username “ftp”, and the password can be anything, even left blank if the FTP Server is set up as described earlier. Note: A blank anonymous password will not work on all types of FTP server, some may require a correctly formatted email address (e.g. a@b.com) as the password. Also, the username ftp is equivalent to typing the username anonymous. 7. Switch the transfer mode to binary, by entering the command bin; 8. Turn on “hash marking”, by entering the command “hash”. This will print “#” symbols across the screen when the transfer is in progress. 9. Transfer a file: The command to receive a file is “recv”, and to send is “send”. Following the command you must enter the name of the file to transfer, and optionally also the name to call the file when it has arrived. For example, to send a file called “500K”, enter: send 500K And to receive a file called “2M”, and locally rename it to “2M_downloaded”, enter: recv 2M 2M_downloaded Note: Some FTP servers are case-sensitive, this is a common reason for a failed download. Remember that Windows does not always display file names with their names in the correct case. To see a list of files in the current directory of the FTP Server, and their exact case sensitive names and file sizes, enter the command “ls –l” (short for: list directory contents, using long format). You can use this command to make sure the files you are intending to transfer are the correct length for the test you wish to perform. a. Wait for the transfer to complete. You will see “#” symbols scrolling across the screen, at a rate proportional to the file transfer speed. You can cancel the transfer by pressing CTRL + C, although the system will take a few seconds to take action and close down the transfer. When the transfer is complete, the session will show you the transferred speed. An example transcript from Airspan’s Product Applications Laboratory is shown in the screenshot below: Note: As the FTP Client shows the speed at which the data in the file was transferred, it will not show you the actual data throughput over the air interface. This is because an allowance of 3.7% must be made to include the protocol headers encapsulating the data. A description of these overheads and the 3.7% calculation is shown in the technical note at the end of this section, along with details of other overheads to consider. Referring to the transfer speed in the screenshot above, the data transfer above resulted in an Ethernet frame throughput to the FTP Client of: 110.33KBytes/sec * 1.037 = 114.4KBytes/sec, or 915.3KBits/sec.
Setup and Test 153 Please refer to the technical note at the end of this section, explaining why the figure will be less than the theoretical maximum data rate available. 10. To exit from the FTP program, type “quit” at the prompt Creating batch files for automatic File Transfers: As mentioned earlier, it will be much more convenient to have test batch files which will automatically perform a file transfer, and then pause to show the results. The command-line FTP program described above can be instructed to use a script file with a set of commands, thus preventing the need to type them every time. Included in the embedded .zip file below are sample files to perform a 10Mbyte download, and a 1Mbyte upload. They are explained below, and if you use them you will need to unzip them into your working FTP directory, and then edit them to use an appropriate IP address for your FTP Server. The files are very small and easy to create, if you do not have a paper copy of this document The FTP program can be invoked using the syntax: ftp –s:filename Where “filename” specifies a text file containing FTP commands; the commands will automatically run after FTP starts. The commands will be almost identical to those used in the “manual” method above, the difference is the use of the “open” command to connect the FTP program to the FTP server. A worked example (note text after the // are comments and must not be included in the file): Contents of “10MB_Download.bat” ftp -s:10M_Download_Script.txt // invoke the FTP program using a script pause // wait for a key press, so you can see the results Contents of “10M_Download_Script.txt” Open 10.0.60.1 // Server IP address: change this to match yours ftp // Username for anonymous access dummypassword@xyz.com // A password, in “email” format bin // Change to Binary mode hash // Turn on “hash marking” recv 10M 10M_ downloadedfile // Get the file “10M” and rename it locally quit // Exit the program To automatically send a file, you will also need another batchfile to call the FTP program with a different script file. The script file will be the same as the one above, except the “recv 10M 10M_downloadedfile” command will be replaced with, e.g. “send 1M 1M_uploadedfile”. Technical Note: An explanation of Ethernet, and Airspan protocol overheads in FTP transfers: The structure and relative sizes of the different portions of an Ethernet frame vary, but a full sized FTP data transfer Ethernet Frame is 1514 Bytes, consisting typically of: 1. 14 Bytes Data Link Control (layer 2 of the OSI 7 Layer model): Containing 6 bytes each of source & sestination MAC addresses, and 2 bytes Ethertype – in this case IP; 2. 20 Bytes Network Layer (layer 3 – in this case IP):Containing source and destination IP addresses, and other information such as IP version, Length, TTL, protocol, checksum, and several flags; 3. 20 Bytes Transport Layer (layer 4 – in this case TCP):Containing source & destination Port numbers, sequence and ACK numbers, TCP Receive Window size, User Data offset position, a checksum, and some flags; 4. 1460 Bytes Application Layer (layer 7 – in this case FTP) – the actual file contents being transferred.
Printed Documentation 154 Therefore the “Ethernet” overhead is 100*1514/1460 = 3.7% Additionally, there is an overhead associated with Airspan’s air interface. The data is sent in small blocks, transmitted every 4ms on multiple RW channels simultaneously. Additionally, an ST can receive up to 4 blocks simultaneously. Each block has a 4 byte overhead. The number of bytes in a block depends on the modulation scheme being used, as per the table below (showing the total bytes/block, including the 4 byte overhead): Modulation Total Bytes/Block QPSK ½ 64 QPSK ¾ 96 16QAM½ 128 16QAM¾ 192 64QAM ¾ 288 As the Ethernet frame size is unlikely to be an exact multiple of the useable Bytes/Block, there will be an additional overhead, as the block containing the last section of an Ethernet frame will have some unused bytes, not completely filled by the end of the frame. Adding the overheads together results in the target throughput figures quoted in the test plan. These numbers have been chosen as realistic figures that should be achieved under laboratory test conditions.
Setup and Test 155 Voice Option Testing Option Module Test It is only possible to fully test the voice module if the installation of the AC and the backhaul connections to the switch are in place. Netspan also needs to be connected. The card is set for 120ohm or 75ohm dependant on the type of backhaul selected on Netspan. When connected to the AC using the correct impedance port the relevant LED should be green. A red LED signifies link disconnection, and an amber LED signifies link present but faulty. Check that the module responds to disconnection of a link. If a switch test is to be undertaken the CT should be connected to a DACU and a voice call made from the DACU to the switch.

Printed Documentation 174 Circuit Board Assemblies Circuit board assemblies must be individually boxed in Airspan-approved shipping containers, to properly protect them from static electricity damage. Static Control Rules Airspan uses state-of-the-art semiconductors to obtain the fastest, most reliable operation. These components are highly sensitive, and can be damaged by a static discharge as low as 250V. Individuals may generate enough static to damage a component without noticing the discharge, so must take precautions to control static. Static Electricity Control All sensitive Printed Circuit Boards (PCBs) must be handled at a static-safe work area. The minimum requirement is a workbench with a grounded work surface, a grounded floor mat, and a wrist strap. When a board is changed at the switch, a portable field service grounding kit must be used. Figure 1 shows the grounded workbench. Figure 1. Printed Circuit Card Workstation All boards must be transported in a static-shielding bag. The following procedures reduce the possibility of static discharge damage: a. Wearing a wrist strap while handling PCBs. b. Attach the string of the Airspan Return and Repair Tag to the ejector/injector of the PCB. c. Insert PCBs into approved static shielding bags with repair tags remaining outside the shielding bag. Do not insert repair tags into static shielding bags. d. Pack/unpack PCBs at a static-safe workbench. e. Transfer boards in a static-shielding bag or non-conductive board container. f. Properly ground storage shelves. g. Properly ground personal wrist straps while transferring boards to the storage shelves. Shipping Boxes WARNING:;A box of boards must not contain other heavy items that could cause part damage. PCBs
General 175 Individually boxed PCBs must be placed into a larger packing case for shipment. Board boxes alone do not sufficiently protect against shipping damage. Empty space in shipping cases must be filled with additional shipping boxes to prevent part movement and damage during handling. Power Supplies And Peripherals Each type of assembly must be shipped in its specifically-designed packing box. Retain individual shipping containers for these items. To prevent damage, all mechanical movable parts (such as disk heads and rotor) must be in the locked/secure position before handling/shipping. All handling must be done using only the handles and/or handholds so the equipment is not damaged. All items must be accompanied by a completed Airspan Return and Repair Tag. Shipment To Airspan The customer should ship the item to the Customer Service Centre at Uxbridge unless Airspan has provided an alternative shipping address. The cost of shipping returns to Airspan for repair shall be borne by the customer, and all risks associated with the shipping remain the responsibility of the customer. Items under repair, and their subsequent return to the customer shall be the responsibility of Airspan. Should the customer specify expedited shipping for the return of a repaired FRU or an advance replacement, all costs incurred shall be borne by the customer. Damaged Shipment If a shipment is received with visible damage to the container, the receiving party should document the damage and report it to the Airspan Customer Service Centre. If concealed damage is found after the shipment is accepted, , the receiving party should document the damage and report it to the Airspan Customer Service Centre. Airspan will arrange for the freight company to inspect the damaged shipment and file an inspection report so that a claim can be initiated.
