Cross Connections | 134 QJET cross connections Expand the E1 / T1 display by clicking on the relevant icons. The QJET card can operate in several modes allowing you greater flexibility in tailoring or grooming traffic. The Data type selection are Off, E1, or T1 rates. Note: An unframed E1 / T1 port requires 5 bits (or 40 kbit/s) of overhead traffic per port for synchronization. An unframed E1 port with 2048 kbit/s of traffic requires 2088 kbit/s of link capacity. An unframed T1 port with 1544 kbit/s of traffic requires 1584 kbit/s of link capacity.
Cross Connections | 135 For each port that you want to put into service, choose the required mode (either Unframed or Framed): Unframed mode Leave the Framed checkbox unticked. Select the required Data type from the drop-down list E1 or T1. Local drop and insert connections are not possible between Unframed E1 / T1 ports. Framed mode Tick the Framed checkbox. Select the required framed mode from the drop-down list: Local drop and insert connections are possible between framed E1 ports on the same interface card or E1 ports on different interface cards. Local drop and insert connections are possible between framed T1 ports on the same interface card or T1 ports on different interface cards. Local drop and insert connections are not possible between framed E1 ports and framed T1 ports.
Cross Connections | 136 E1 Framed Modes Framed Mode Description E1 – PCM 30 Provides 30 timeslots to transport traffic. Timeslot 16 carries channel associated signalling data (CAS). E1 – PCM 31 Provides 31 timeslots to transport traffic. Timeslot 16 can be used for common channel signalling or to transport traffic. E1 – PCM 30C Same as E1 – PCM 30 mode but supports CRC-4. E1 – PCM 31C Same as E1 – PCM 31 mode but supports CRC-4. E1 CRC-4 (cyclic redundancy check) is used to ensure correct frame alignment and also used to gather E1 performance statistics e.g. Errored Seconds (ES), Severely Errored Seconds (SES). The first three bits of timeslot 0 NFAS (bits 0,1 & 2) and all of timeslot 0 FAS are not transported across the link, but rather terminated and regenerated at each terminal. The last five bits of timeslot 0 NFAS (bits 3 – 7) are the National Use Bits (NUBs) which can be cross connected locally or over the link. E1 - PCM 30 mode E1 - PCM 30 modes are used when access to the signalling bits (ABCD) is required, for example:  Splitting a PCM 30 E1 into two separate PCM 30 E1s  Cross connecting signalling from DFXS, DFXO or Q4EM interfaces into an PCM 30 E1  Drop and Insert connections between PCM 30 E1s In PCM 30 / PCM 30C mode, the timeslot table left column is used to map timeslot bits and the timeslot table right column is used to map CAS bits (ABCD) for signalling. Timeslot 16 is reserved to transport the CAS multi frame. One use of this mode is to connect the 4 wire E&M interfaces to third-party multiplexer equipment over the E1 interface using CAS in TS16 to transport the E&M signalling. To configure this mode correctly, you must have a detailed knowledge of the CAS signalling modes for the third-party equipment to ensure the signalling bits are compatible and configured to interoperate. E1 - PCM 31 mode E1 - PCM 31 modes are used to cross connect timeslots bits without the signalling bits (ABCD). TS16 can be cross connected between E1 ports (to transport the entire CAS multi frame) or used for common channel signalling or to transport traffic. The timeslot table left column is used to map timeslot bits but the timeslot table right column for CAS bits (ABCD) is not used.
Cross Connections | 137 T1 Framed Modes Framed Mode Description T1 - SF Provides 24 timeslots to transport traffic using the G.704 12 frame Super Frame without signalling. There is no CRC capability with the SF. T1 – SF 4 Provides 24 timeslots to transport traffic using the G.704 12 frame Super Frame with 4 state signalling (AB bits).

T1 - SF mode T1 SF mode provides 24 timeslots to transport traffic using the G.704 12 frame Super Frame without demultiplexing the signalling. Complete timeslots can be cross connected including the inherent robbed signalling bits. The timeslot table left column is used to map timeslot bits but the timeslot table right column for CAS bits (ABCD) is not used. T1 SF mode is used when access to the signalling bits is not required but are transported between T1s, for example:  Drop and Insert connections between 12 frame Super Frame T1s or data interfaces T1 - SF 4 mode T1 SF 4 mode provides 24 timeslots to transport traffic using the G.704 12 frame Super Frame with four state demultiplexed signalling using the AB bits. The mapping left column is used to map timeslot bits and the timeslot table right column is used to map the CAS A&B bits for signalling (C&D bits are not used). T1 SF mode is used when access to the signalling bits is required, for example:  Cross connecting signalling from DFXS, DFXO or Q4EM interfaces into a 12 frame Super Framed T1 using ‘multiplexed’ signalling from the interface.  Drop and Insert connections between 12 frame Super Framed T1s or data interfaces T1 - ESF mode T1 ESF mode provides 24 timeslots to transport traffic using the G.704 12 frame Extended Super Frame without demultiplexing the signalling.

On the other side of the link, expand the corresponding DFXO display, as required, by clicking . 3. For the DFXS card and corresponding DFXO card, select the Signalling type as required, according to the table below. The CAS signalling between DFXO / DFXS interfaces uses 4RF proprietary allocation of control bits. The Signalling type affects both ports of the DFXO / DFXS interface. If a mixture of signalling types is required, then multiple DFXO / DFXS cards are needed. Signalling Application Overhead Multiplexed (default) Multiplexers the four ABCD bits from the interface into a single 8 kbit/s channel. Use when interworking DFXO to DFXS, between an XE and a SE radio or when limited bandwidth is available. This signalling type cannot be used for interworking between framed E1 and voice interfaces. 8 kbit/s Non-multiplexed Transports each of the four ABCD bits in separate 8 kbit/s channels. Use when interworking DFXO cards to DFXS cards or when signalling bits are mapped into an E1 / T1 timeslot. 32 kbit/s 4 wire compatible Use when interworking the DFXO card or DFXS card to a Q4EM interface • DFXS to DFXO A bit mapped to off-hook • DFXO to DFXS A bit mapped to fault 8 kbit/s 4. Set the Voice capacity and create the Voice connection by dragging and dropping between the mapping connection boxes of the DFXO and DFXS corresponding ports. 5.

Cross Connections | 148 Symmetrical Connection Wizard The Cross Connections application has a Symmetrical Connection Wizard which simplifies the cross connection configuration when the terminals are fitted with symmetrical / matching interface types. A symmetrical connection is a connection between the local and the remote terminal where the local slot, card type, port and connection details are identical to those of the remote terminal. The only exception is DFXO / DFXS connections where DFXO cards are considered to match DFXS cards (as they normally interwork). Framed E1 / T1 CAS connections, drop-and-insert connections, and connections that do not involve entire timeslots, are considered to be asymmetrical. Starting the wizard When starting the wizard with unsaved changes, the following popup dialog should appear Click on 'Save' if you wish to save the current configuration to a file. Clicking on 'Continue' will continue with the wizard and overwrite any changes made when the wizard finishes. The wizard can be cancelled at any time by clicking on the 'Cancel' button or by closing the window. Wizard Navigation Click on the Next button to progress through the wizard. The current stage is indicated in the navigation bar on the left. You can jump directly to a stage by clicking on the stage required.

If the IP addresses are not displayed, enter the IP addresses of the local and remote terminals. Click on 'Get Configuration' to upload the existing cross connections configuration from the local terminal. The Radio bandwidth bar will show the available bandwidth and will be updated as bandwidth is assigned to cards. Setting the bandwidth If the Cross Connections Application is opened from SuperVisor, the Total Capacity of the radio link will be shown in the Bandwidth field. If the Cross Connections Application is opened as a stand alone application, the Total Capacity of the radio link will be need to be entered in the Bandwidth field. The 'Remove asymmetrical connections' button will be active if there are existing asymmetrical cross connections. If you want to remove existing asymmetrical cross connections, click on this button. The Radio bandwidth bar will update accordingly.
Cross Connections | 150 Card Selection If the Cross Connections Application is opened from SuperVisor, existing cards installed in the local terminal that match cards installed in the remote terminal will be displayed. Mismatched cards will be shown as 'Empty Slot'. If the Cross Connections Application is opened as a stand alone application, select the card types that will be fitted in the terminal. To copy the card type selected in Slot A to all the other slots (B – H), click on the Copy Card button. This assumes that the same interface card types are fitted in all the card slots.

Protected terminals | 153 11. Protected terminals Monitored Hot Stand By (MHSB) This section describes configuring the protected terminal in MHSB mode. A protected terminal in MHSB mode comprises two radios interconnected using the tributary and RF switches as shown below: The MHSB switch protects terminals against any single failure in one radio. It also monitors the alarm output of each radio and switches between radios if major radio link alarms occur. The MHSB switch uses a CPU to monitor the alarm status received from both the connected radios' alarm ports. When a relevant major radio link alarm is detected on the active radio (that is, transmitter, receiver, power supply or modem), the CPU switches a bank of relays that switches all the interfaces and the transmit port from the main radio to a functioning stand-by radio. The stand-by radio now becomes the active radio. The tributary switch and the RF switch are both a 19-inch rack-mount 1U high chassis. The total rack space required is 6U. The MHSB switch option is available for the following bands: 300, 400, 700, 900, 1400, 2000, and 2500 MHz.

Protected terminals | 156 RF protection switch LEDs LED Colour Appearance Explanation Tx A Green Solid RF is being received from radio A Tx B Green Solid RF is being received from radio B On Blue Solid Indicates that there is power to the RF protection switch Slave tributary switches Each tributary switch protects up to eight ports. Up to three slave tributary switches may be added to a MHSB terminal to protect up to 32 ports. Each slave tributary switch is interconnected by means of the slave tributary switch ports on the RF switch, as shown below. Note: A tributary switch that is operating as a slave (rather than a master) has a RJ-45 V.24 loopback connector plugged into the console port. If the connector is missing, contact Customer Support. Alternatively, you can make this connector. Follow the standard pinouts for a V.24 RJ-45 connection (see "QV24 Interface connections" on page 228).
Protected terminals | 157 MHSB cabling The two radios are interconnected as follows: Caution: Do not connect Transmit to Receive or Receive to Transmit as this may damage the radio or the MHSB switch. Cables supplied with MHSB The following cables are supplied with a MHSB terminal:  Ethernet interface: RJ-45 ports standard TIA-568A patch cables .  Alarm interface: RJ-45 ports standard TIA-568A patch cables.  RF ports: two QMA male patch cables are supplied. MHSB power supply See “DC power supply” on page 32 and “AC power supply” on page 35.
Protected terminals | 158 Configuring the radios for protected mode The MHSB switch does not require any special software. However, the radios connected to the MHSB switch must be configured to work with the MHSB switch. This sets the alarm outputs and inputs to function in MHSB mode. You must configure the interfaces of both radios connected to the MHSB switch identically. To perform this, you can either connect directly to the radio or use the test mode of the MHSB switch. IP address setup Before configuring the link, you must ensure that the two independent links have correctly configured IP address details. All four radios in the protected link must be on the same subnet.
Protected terminals | 159 Mounting the MHSB radios and switch Once the IP addresses are correctly configured, it is important to connect the A and B radios' Ethernet and Alarm ports correctly. In general, mount radio A above the MHSB switch and radio B below the MHSB switch: There is an Ethernet connection between any of the four Ethernet ports on each radio and the Ethernet port on the Tributary switch. There is also a connection between radio A and radio B, which ensures Ethernet traffic is maintained if a radio loses power. The Ethernet port on the protection switch can be connected to an Ethernet hub or switch to allow multiple connections. Important: The management Ethernet capacity on each of the four radios in the protected terminal must be identical for remote communications to work and there should only be one IP connection to the management network (via the tributary switch Ethernet port).
Protected terminals | 160 Configuring the terminals for MHSB It is recommended that you configure the local and remote A side first, then the local and remote B side. Both the local A and B radios must be configured identically, and both the remote A and B radios must be configured identically. Tip: As illustrated below, you may find it helpful to have two browser sessions running simultaneously. You can then easily see both the A and B sides of the protected link. To configure MHSB operation: 1. Select Link > Maintenance > MHSB. 2. Enable MHSB mode. 3. Select whether the radio is A or B. Ensure that the radio connected to the A side of the protection switch (normally above the MHSB switch) is set to Radio A and the radio connected to the B side of the protection switch (normally below the MHSB switch) is set to Radio B. In the event of a power outage, the radios will switch over to the A side of the protection switch when the power is restored. The A side is also the default active side. 4. When you have made your changes, click Apply to apply changes or Reset to restore the previous configuration. 5. Repeat steps 2 to 4 for the other side of the protected link.
Protected terminals | 161 Clearing MHSB alarms If a switchover event occurs, the OK LED on the front panel and on the Terminal status and menu bar in SuperVisor changes to orange. 1. Select Clear Switched Alarm from the MHSB Command drop-down list. 2. Click Apply to apply changes or Reset to reset the page. Note: When MHSB mode is enabled, external alarm input 2 is used by the protection system to carry alarms from the protection switch to the radio. In MHSB mode, therefore, only external alarm input 1 is available for user alarms.
In-service commissioning | 163 12. In-service commissioning Before you start When you have finished installing the hardware, RF and the traffic interface cabling, the system is ready to be commissioned. Commissioning the terminal is a simple process and consists of: 1. Powering up the terminals 2. Configuring both the local and remote terminals using SuperVisor 3. Aligning the antennas 4. Synchronizing the terminals 5. Testing the link is operating correctly. As a minimum, conduct the suggested tests to ensure correct operation. More extensive testing may be required to satisfy the end client or regulatory body requirements. 6. Connecting up the client or user interfaces What you will need  Appropriately qualified commissioning staff at both ends of the link.  Safety equipment appropriate for the antenna location at both ends of the link.  Communication equipment, that is, mobile phones or two-way radios.  SuperVisor software running on an appropriate laptop, computer, or workstation at one end of the link.  Tools to facilitate loosening and re-tightening the antenna pan and tilt adjusters.  Predicted receiver input levels and fade margin figures from the radio link budget (You can use Surveyor (see "Path planning" on page 19) to calculate the RSSI, fade margin, and availability).
In-service commissioning | 164 Applying power to the terminals Caution: Before applying power to a terminal, ensure you have connected the safety earth and antenna cable. Apply power to the terminals at each end of the link. When power is first applied, all the front panel LEDs will illuminate red for several seconds as the system initializes. After the system is initialized, the OK LED on the front panel should illuminate green and if the terminals are correctly configured, the TX and RX LED should also be illuminated green. If the RX LED is:  Red — the antennas are may be significantly mis-aligned with no signal being received.  Orange — the antennas may be roughly aligned with some signal being received.  Green — the antennas are well-aligned and adequate signal is being received to create a reliable path. If the TX LED is:  Red — there is a fault in the antenna or feeder cable, or the transmitter is faulty.  Green — this means the transmitter is working normally. Review the link configurations using SuperVisor 1. Connect a PC, with SuperVisor installed, to both terminals in the link. 2. Log into the link. 3. Select Link > Summary and confirm the following basic information:  Terminal IP address(es)  Terminal TX and RX frequencies  RSSI (dBm)  TX power (dBm)  SNR (dBm) Note: If the terminals have not already been configured, refer to "Configuring the terminal" on page 61, "Configuring the traffic interfaces" on page 77, and "Configuring the traffic cross connections" on page 121.
In-service commissioning | 165 Antenna alignment For any point-to-point link, it is important to correctly align the antennas to maximize the signal strength at both ends of the link. Each antenna must be pointing directly at the corresponding antenna at the remote site, and they must both be on the same polarization. The antennas are aligned visually, and then small adjustments are made while the link is operating to maximize the received signal. Directional antennas have a radiation pattern that is most sensitive in front of the antenna, in line with the main lobe of the radiation pattern. There are several other lobes (side lobes) that are not as sensitive as the main lobe in front of the antenna. For the link to operate reliably, it is important that the main lobes of both antennas are aligned. If any of the side lobes are aligned to the opposite antenna, the received signal strength of both terminals will be lower, which could result in fading. If in doubt, check the radiation patterns of the antennas you are using. Checking the antenna polarization Check that the polarization of the antennas at each end of the link is the same. Antenna polarization of grid antennas are normally indicated by an arrow or with “H” and “V” markers (indicating horizontal and vertical). On Yagi antennas, ensure the orientation of the elements are the same at each end of the link. Transmit frequency and power, and antenna polarization would normally be defined by a regulatory body, and typically licensed to a particular user. Refer to your license details when setting the antenna polarization.
In-service commissioning | 166 Visually aligning antennas 1. Stand behind the antenna, and move it from side to side until it is pointing directly at the antenna at the remote site. The remote antenna may be made more visible by using a mirror, strobe light, or flag. If the remote end of the link is not visible (due to smoke, haze, or local clutter, etc), align the antenna by using a magnetic compass. Calculate the bearing using a scale map of the link path. When setting the antenna on the desired bearing ensure that you use the appropriate true-north to magnetic-north offset. Also ensure that the compass reading is not affected by standing too close to metallic objects. 2. Once the antenna is pointing at the remote antenna, tighten the nuts on the U-bolt or antenna clamp just enough to hold it in position. Leave the nuts loose enough so that small adjustments can still be made. Check that the antenna is still pointing in the correct direction. 3. Move the antenna up or down until it is pointing directly at the remote site. 4. Tighten the elevation and azimuth adjustment clamps. 5. Mark the position of the antenna clamps so that the antenna can be returned to this rough aim point easily when accurately aligning the antennas. 6. Repeat steps 1-5 at the opposite site. Note: Low gain antennas need less adjustment in elevation as they are simply aimed at the horizon. They should always be panned horizontally to find the peak signal.
In-service commissioning | 167 Accurately aligning the antennas Once the antennas are visually aligned, accurately align both antennas by carefully making small adjustments while monitoring the RSSI. This will give the best possible link performance. Note: Remember that it is important to align the main radiation lobes of the two antennas to each other, not any side lobes. It may be easier to perform this procedure if you can communicate with someone at the remote site by telephone, mobile, or two-way radio. 1. Connect a laptop PC running SuperVisor software and power up the terminals at both ends of the link. Select Link > Performance > Summary so that you can see the RSSI indication for the local terminal. Alternatively, use the RSSI test point on the front panel together with a multimeter (see "6Measuring the RSSI” on page 168). 2. Move the antenna through a complete sweep horizontally (known as a 'pan') either side of the point established in the visual alignment process above. Note down the RSSI reading for all the peaks in RSSI that you discover in the pan. 3. Move the antenna to the position corresponding to the maximum RSSI value obtained during the pan. Move the antenna horizontally slightly to each side of this maximum to find the two points where the RSSI drops slightly. 4. Move the antenna halfway between these two points and tighten the clamp. 5. If the antenna has an elevation adjustment, move the antenna through a complete sweep (known as a 'tilt') vertically either side of the point established in the visual alignment process above. Note down the RSSI reading for all the peaks in RSSI that you discover in the tilt. 6. Move the antenna to the position corresponding to the maximum RSSI value obtained during the tilt. Move the antenna slightly up and then down from the maximum to find the two points where the RSSI drops slightly. 7. Move the antenna halfway between these two points and tighten the clamp. 8. Recheck the pan (steps 2-4) and tighten all the clamps firmly. 9. Perform steps 1-8 at the remote site.
In-service commissioning | 168 Measuring the RSSI Measure the RSSI value with a multimeter connected to the RSSI test port on the front of the terminal (see "Front panel connections and indicators" on page 27). 1. Insert the positive probe of the multimeter into the RSSI test port, and clip the negative probe to the chassis of the terminal (earth). 2. Pan and tilt the antenna until you get the highest VDC reading. The values shown in the table below relate the measured VDC to the actual received signal level in dBm regardless of bandwidth and frequency. RSSI test port value (VDC) RSSI reading (dBm) RSSI test port value (VDC) RSSI reading (dBm) RSSI test port value (VDC) RSSI reading (dBm) 0.000 - 100 0.675 - 73 1.350 - 46 0.025 - 99 0.700 - 72 1.375 - 45 0.050 - 98 0.725 - 71 1.400 - 44 0.075 - 97 0.750 - 70 1.425 - 43 0.100 - 96 0.775 - 69 1.450 - 42 0.125 - 95 0.800 - 68 1.475 - 41 0.150 - 94 0.825 - 67 1.500 - 40 0.175 - 93 0.850 - 66 1.525 - 39 0.200 - 92 0.875 - 65 1.550 - 38 0.225 - 91 0.900 - 64 1.575 - 37 0.250 - 90 0.925 - 63 1.600 - 36 0.275 - 89 0.950 - 62 1.625 - 35 0.300 - 88 0.975 - 61 1.650 - 34 0.325 - 87 1.000 - 60 1.675 - 33 0.350 - 86 1.025 - 59 1.700 - 32 0.375 - 85 1.050 - 58 1.725 - 31 0.400 - 84 1.075 - 57 1.750 - 30 0.425 - 83 1.100 - 56 1.775 - 29 0.450 - 82 1.125 - 55 1.800 - 28 0.475 - 81 1.150 - 54 1.825 - 27 0.500 - 80 1.175 - 53 1.850 - 26 0.525 - 79 1.200 - 52 1.875 - 25 0.550 - 78 1.225 - 51 1.900 - 24 0.575 - 77 1.250 - 50 1.925 - 23 0.600 - 76 1.275 - 49 1.950 - 22 0.625 - 75 1.300 - 48 1.975 - 21 0.650 - 74 1.325 - 47 2.000 - 20
In-service commissioning | 169 Synchronizing the terminals After you have completed the alignment of the two antennas, you must ensure the two terminals are synchronized. The terminals are synchronized when:  the OK LED is green, which indicates that no system alarms are present, and  the RX LED is green, which indicates a good signal with no errors, and  the TX LED is green, which indicates that there are no transmitter fault conditions. Checking performance The amount of testing performed on the completed installation will depend on circumstances. Some customers may need to prove to a local licensing regulatory body that the link complies with the license provisions. This may require special telecommunications test equipment to complete these tests. Most customers simply want to confirm that their data traffic is successfully passing over the link, or that the customer interfaces comply with known quality standard. However, the most important performance verification checks are:  Receive input level  Fade margin  Long-term BER Checking the receive input level The received signal strength at the local terminal is affected by many components in the system and has a direct relationship with the resulting performance of the link. A link operating with a lower than expected signal strength is more likely to suffer from degraded performance during fading conditions. The receive input level of a link is normally symmetrical (that is, similar at both ends). 1. Compare the final RSSI figure obtained after antenna alignment with that calculated for the link. 2. If the RSSI figure is in excess of 3 dB down on the predicted level, recheck and correct problems using the table below and then recheck the RSSI. Alternatively, recheck the link budget calculations. Possible cause Terminal(s) Is the terminal operating on the correct frequency? Local & remote Is the remote terminal transmit power correct? Remote Are all the coaxial connectors tight? Local & remote Is the antenna the correct type, that is, gain and frequency of operation? Local & remote Is the antenna polarized? Local & remote Is the antenna aligned? Local & remote Is the path between the terminals obstructed? Note: If following the above steps does not resolve the situation, contact Customer Support for assistance. 3. Record the RSSI figure on the commissioning form. 4. Repeat steps 1 to 2 for the other end of the link.
In-service commissioning | 170 Checking the fade margin The fade margin is affected by many components in the system and is closely related to the received signal strength. A link operating with a lower than expected fade margin is more likely to suffer from degraded performance during fading conditions. A reduced fade margin can be due to operating the link too close to the noise floor, or the presence of external interference. The fade margin of a link can be asymmetrical (that is, different at each end). Possible causes of low fade margin are as follows: Problem Terminal Low receive signal strength (see above table) Local and Remote Interfering signals on the same, or very close to, the frequency of the local terminal receiver. Local Intermodulation products that land on the same or very close to the frequency of the local terminal receiver. Local or Remote Operating near the local receiver noise floor Local To check the fade margin: 1. Confirm (and correct if necessary) the receive input level (see the previous test). Note: If the receive input level is lower than expected, the fade margin may also be low. 2. Select Link > Performance > Summary and check the current BER of the link in its normal condition is better than 10-6 (If necessary, clear out any extraneous errors by clicking Reset Counters). 3. Check the signal to noise (S/N) indication on the Link > Performance > Summary page. This shows the quality of the signal as it is being processed in the modem. It should typically be better than 30 dB. If it is less than 25 dB, it means that either the RSSI is very low or in-band interference is degrading the S/N performance. 4. Temporarily reduce the remote site's transmit power using either an external attenuator or SuperVisor (Remote > Terminal > Basic). Note: Ideally, the transmit power of the remote site should be reduced by up to 20 dB, which will require the use of an external 50 ohm coaxial attenuator capable of handling the transmit power involved. In the absence of an attenuator, reduce the transmit power using SuperVisor. 5. Check and note the current BER of the link in its now faded condition (Again, if necessary, clear out any extraneous errors (introduced by the power reduction step above) by clicking Reset Counters). 6. Compare the unfaded and faded BER performance of the link (steps 2 and 4). Continue to reduce the remote transmit power until either the BER drops to 10-6 or the remote transmitter power has been reduced by 20 dB. Note: The fade margin of the link is expressed as a number (of dB) that the link can be faded (transmitter power reduced) without reducing the BER below operating specifications (1 * 10-6 BER). A 20 dB fade margin is adequate for most links.
In-service commissioning | 171 7. Record the fade margin and SNR results on the commissioning form. Note: If the transmit power is reduced using SuperVisor rather than an external attenuator, the fade margin should be recorded as “Greater than x dB” (where x = the power reduction). 8. Restore the remote terminal transmit power to normal. 9. Repeat steps 1 to 7 for the other end of the link. Note: If following all the guidelines above does not resolve the situation, contact Customer Support for assistance. Checking long-term BER The BER test is a measure of the stability of the complete link. The BER results of a link can be asymmetrical (that is, different at each end). 1. Select Link > Performance > Summary and check the current BER and error counters of the link. (If necessary, clear out any extraneous errors by selecting Reset Counters). 2. Wait 15 minutes, and check the BER display and error counters again. If there are a small number of errors and the BER is still better than 10-9, continue the test for 24 hours. If there are a significant number of errors, rectify the cause before completing the 24 hour test. Note: It is normal to conduct the BER test in both directions at the same time, and it is important that no further work be carried out on the equipment (including the antenna) during this period. 3. The BER after the 24 hour test should typically be better than 10-8. 4. Record the BER results on the commissioning form. Bit Error Rate tests A Bit Error Rate (BER) test can be conducted on the bench, (see “Bench setup” on page 37). Attach the BER tester to the interface port(s) of one terminal, and either another BER tester or a loopback plug to the corresponding interface port of the other terminal. This BER test can be carried out over the Ethernet, E1/T1, V.24 or HSS interfaces. It will test the link quality with regard to user payload data. Caution: Do not apply signals greater than -20 dBm to the antenna as they can damage the receiver. In a bench setup, there must be 60 - 80 dB at up to 2 GHz of 50 ohm coaxial attenuation (capable of handling the transmit power) between the terminals’ antenna connectors.
In-service commissioning | 172 Additional tests Depending on license requirements or your particular needs, you may need to carry out additional tests, such as those listed below. Refer to the relevant test equipment manuals for test details. Test Test equipment required TX power output measurements (at TX and duplexer outputs) Power meter TX spectrum bandwidth Spectrum analyzer TX spectral purity or harmonic outputs Spectrum analyzer TX center frequency Frequency counter or spectrum analyzer Bulk capacity BER test BER tester LAN throughput or errors LAN tester G.703 / HDB3 waveforms Digital oscilloscope Serial interface BER BER tester Audio quality PCM4 or SINAD test set
In-service commissioning | 173 Checking the link performance For a graphical indication of the link performance, you can use the constellation analyzer. The 'dots' are a graphical indication of the quality of the demodulated signal. Small dots that are close together indicate a good signal. If the dots become spaced further apart, this indicates that the signal quality is degrading. This signal quality degradation can be caused by low Rx signal level due to, for example:  external interference  failure of any of the following: modem, receiver, far end transmitter, an antenna (either end), a feeder or connector (for example, due to water damage)  path issues such as multi-path fading or obstructions To check the performance of the link using the constellation analyzer: 1. Select Link or Local or Remote > Performance > Constellation. A blank constellation diagram appears: 2. Click Start to start the constellation analyzer. While the constellation analyzer is running, the terminal will temporarily stop collecting error performance statistics. If you want to run the constellation analyzer anyway, click OK when you see this warning message: 3. Click Stop to stop the constellation analyzer. The terminal automatically resumes collecting error performance statistics.

Maintenance | 175 13. Maintenance There are no user-serviceable components within the terminal. All hardware maintenance must be completed by 4RF or an authorized service centre. Do not attempt to carry out repairs to any boards or parts. Return all faulty terminals to 4RF or an authorized service centre. For more information on maintenance and training, please contact Customer Services. Caution: Electro Static Discharge (ESD) can damage or destroy the sensitive electrical components in the terminal. Routine maintenance Every six or twelve months, for both ends of the link, you should record the RSSI and SNR levels as well as checking the following: Item What to check or look for Equipment shelter environment Water leaks Room temperature Excessive vibration Vermin damage Terminal mounting Firmly mounted Antenna cable connections Tight and dry Antenna cable and its supports Not loose or suffering from ultra-violet degradation Antenna and its mounting hardware Not loose, rusty or damaged Safety earth Connections tight Cabling intact DC system Connections tight Voltage in normal limits Batteries (if installed) Connections tight Electrolyte levels normal
Maintenance | 176 Terminal upgrades You can upgrade all software for both terminals remotely (through a management network), which eliminates the need to physically visit either end of the link. The best method of upgrading a terminal is to use the TFTP server method (see “Upgrading the terminal using TFTP” on page 177). This method downloads all the required image files into the terminal and then activates the correct files following a terminal reboot. A terminal can also be upgraded by download all the required system software files (see “Upgrading the terminal by uploading system files” on page 182”). Upgrade process To minimize disruption of link traffic and prevent your terminals from being rendered inoperative, please follow the procedures described in this section together with any additional information or instructions supplied with the upgrade package. Before upgrading the terminal, ensure that you have saved the configuration file (see "Saving the terminal's configuration" on page 66) as well as the cross connection configuration (see "Saving cross connection configurations" on page 130). The Remote terminal upgrade process will be faster if the bandwidth allocated to the management ethernet capacity is maximized. The terminal software must be identical at both ends of the link. At the end of the terminal upgrade process, the versions of image files (kernel software, and firmware) that were in use before the upgrade are still in the terminal. You can restore them, if required, by editing the image tables and reactivating the old files (see “Changing the status of an image ” on page 188). IMPORTANT NOTE: Ensure you are logged into the Near end terminal before you start an upgrade. Installing RF synthesizer configuration files If you are upgrading from software version 5_x_x or greater, refer to “Upgrading the terminal using TFTP” on page 177). If you are upgrading from a software version prior to 7_1_x, you will need to install new RF synthesizer files, refer to “Configuration files” on page 182. You can then upgrade the terminal using TFTP (on page 177). Frequency Band Synthesizer File(to be installed) 300 MHz XE_300_400_synth.cfg 400 MHz XE_300_400_synth.cfg 700 MHz XE_600_700_800_900_synth.cfg 800 MHz XE_600_700_800_900_synth.cfg 900 MHz XE_600_700_800_900_synth.cfg 1400 MHz XE_1400_synth.cfg 2000 MHz XE_2000_2500_synth.cfg 2500 MHz XE_2000_2500_synth.cfg If you are upgrading from software version 3_x_x or 4_x_x, refer to “Upgrading the terminal by uploading system files” on page 182.
Maintenance | 177 Upgrading the terminal using TFTP Before upgrading the terminal, ensure that you have saved the configuration file (see "Saving the terminal's configuration" on page 66) as well as the cross connection configuration (see "Saving cross connection configurations" on page 130). Upgrading the terminal using the TFTP (Trivial File Transfer Protocol) server involves these steps: 1. Run the TFTP server. 2. Login to the Near end terminal / local terminal (see “IP addressing of terminals” on page 47). 3. Run the TFTP upgrade process on the Remote terminal. 4. Reboot the Remote terminal. 5. Run the TFTP upgrade process on the Local terminal. 6. Reboot the Local terminal. 7. Clear the Java and web browser caches. Step 1: Run the TFTP server 1. Double-click tftpd32.exe (located in the TFTPD directory) from the Aprisa CD supplied with the product. Leave the TFTPD32 application running until the end of the upgrade process. 2. Click Settings and make sure that both SNTP server and DHCP server are not selected (no tick), and click OK. 3. Click Browse and navigate to the root directory on the Aprisa CD (for example, D:\) supplied with the product, then click OK. 4. Note down the IP address of the TFTP server (shown in the Server Interfaces drop-down list in the TFTPD32 window) as you will need it later.
Maintenance | 178 Step 2: Log into the Local terminal Use SuperVisor to log into the Near end terminal (now the Local terminal) (see “IP addressing of terminals” on page 47) with either 'modify' or 'admin' privileges. Step 3: Run the TFTP upgrade process on the Remote terminal 1. Select Remote > Maintenance > Upload > TFTP Upgrade. 2. Enter the IP address of the TFTP server (that you noted earlier) 3. Enter the version number of the software that you are upgrading to as a three digit number separated by underscores, for example, 7_3_2. 4. Click Apply and check the TFTP server for download activity. The Upgrade Result changes from 'Executing' to either 'Succeeded' or 'Failed'. Note: This may take several minutes when upgrading the remote terminal. If the upgrade has failed:  The TFTP server IP address may be set incorrectly  The 'Current Directory' on the TFTP server was not pointing to the location of the upload config file e.g. 'Rel_7_3_2.cfg' .  There may not be enough free space in the image table to write the file. Inactive images can be deleted (and the terminal rebooted) to free up space for the new image (see “Changing the status of an image file” on page 188). Step 4: Reboot the Remote terminal Reboot the remote terminal before proceeding with the next step of the upgrade process (see “Rebooting the terminal” on page 189). 1. Select Remote > Maintenance > Reboot and select [Hard Reboot] Communications to SuperVisor remote page will fail until the remote terminal reboot has completed.
Maintenance | 179 Step 5: Run the TFTP upgrade process on the Local terminal. 1. Select Local > Maintenance > Upload > TFTP Upgrade. 2. Enter the IP address of the TFTP server (that you noted earlier) 3. Enter the version number of the software (that you are upgrading to) for example, 7_3_2. 4. Click Apply and check the TFTP server for download activity. The Upgrade Result changes from 'Executing' to either 'Succeeded' or 'Failed'. Note: This may take several minutes when upgrading the remote terminal. Step 6: Reboot the Local terminal Reboot the local terminal before proceeding with the next step of the upgrade process (see “Rebooting the terminal” on page 189). 1. Select Local > Maintenance > Reboot and select [Hard Reboot] 2. Log back into the Local terminal when the reboot has completed. Step 7: Clear the Java and web browser caches After upgrading the terminal you should clear the Java and web browser caches. The files stored in them may cause the SuperVisor and Cross Connections applications to display incorrectly. To clear the Java cache (Windows XP): 1. Select Start > Control Panel. 2. Select Java Plug-in 3. Click the Cache tab. 4. Click Clear and then click OK to confirm.
Maintenance | 180 To clear your web browser cache (Mozilla Firefox 1.x and above): 1. Select Tools > Options. 2. Select Privacy and then click Cache. 3. Click Clear to clear the cache, and then click OK to confirm.
Maintenance | 181 To clear your web browser cache (Internet Explorer 6.x and above): 1. Select Tools > Internet Options. 2. On the General tab, click Delete Files, and then click OK to confirm.
Maintenance | 182 Upgrading the terminal by uploading system files A terminal can also be upgraded by uploading specific system files: configuration files, kernel image files, software image files or firmware image files. Note: You should only upgrade components that need changing. It is not always necessary, for instance, to replace kernel or software files when upgrading a single firmware file. If interdependency exists between file types, this will be made clear in the documentation that accompanied the update package. Configuration files Configuration files (.cfg) are compressed archives containing a script to instruct the terminal on how to handle the other files in the archive. Uploading of configuration files can only be performed to the Local Terminal (not via the link to the Remote Terminal). RF synthesizer configuration files The RF synthesizer configuration archive contains files that provide values for the transmitter and receiver synthesizers to operate across the supported frequency bands. Synthesizer configuration filenames have the following format: XE_(frequency bands)_synth.cfg e.g. XE_300_400_synth.cfg Modem configuration files The Modem configuration archive contains files that provide values for the Modem to operate at the various supported channel sizes and modulation types. Modem configuration filenames have the following format: modem_(version number).cfg e.g. modem_7_1_4.cfg Cross-connect configuration files The Cross-connect configuration archive contains the Cross Connections application program that can be launched from within SuperVisor. Cross-connect configuration filenames have the following format: C-crossconnect_(version number).cfg e.g. C-crossconnect_7_1_4.cfg
Maintenance | 183 To upload a configuration file: 1. Select Local > Maintenance > Config Files > Upload Configuration 2. Browse to the location of the file required to be uploaded into the terminal *.cfg. 3. Click on Upload. The normal response is Succeeded if the file has been loaded correctly. A response of ‘Failed’ could be caused by: • Not enough temporary space in the filesystem to uncompress the archive and execute the script • A file or directory expected by the script not being present on the filesystem 4. Reboot the terminal using a ‘Hard Reboot’ (see “Rebooting the terminal” on page 189).
Maintenance | 184 Image Files Image files (.img) are loaded into the terminal and either contains code that is executed by the system processor, or contain instructions to configure the various programmable logic elements. The image file types that can be uploaded are: • Kernel image files • Software image files • Firmware image files Note: The Bootloader image file C-CC-B-(version number).srec and Flash File System image file C-CC-F-(version number).img can only be changed in the factory. Uploading of image files can only be performed to the local terminal (not via the link to the remote terminal). To upload and activate an image file: 1. Upload the required image file. If the Upload Status page show ‘executing’, then ‘writing to flash’, then ‘Succeeded’, then the file has been written into the image table correctly. If the Upload Status is ‘Failed’, there may not be enough free space in the image table to write the file. Inactive images can be deleted (and the terminal rebooted) to free up space for the new image (see “Changing the status of an image file” on page 188). 2. Set the status of the image to ‘activate’ (see “Changing the status of an image ” on page 188). This actually sets the status to ‘Selected’ until after a terminal reboot. 3. Reboot the terminal using a ‘Hard Reboot’ (see “Rebooting the terminal” on page 189). This activates the selected image. The image table status will now show ‘Active’. The previous image file status will now show as ‘Inactive’.
Maintenance | 185 Kernel image files Kernel image files contain code that forms the basis of the microprocessor’s operating system. There can only ever be two kernel image files in the image table, the active and the inactive. Kernel filenames have the following format: C-CC-K-(version number).img e.g. C-CC-K-7_1_4.img To upload a kernel image file; 1. Select Local > Maintenance > Upload > Kernel 2. Browse to the location of the file required to be uploaded into the terminal *.img. 3. Click on Upload. 4. Activate the image (see “Changing the status of an image file” on page 188). 5. Reboot the terminal using a ‘Hard Reboot’ (see “Rebooting the terminal” on page 189). Software image files Software image files contain code that forms the basis of the terminal’s application and management software (including the Web-based GUI). There can only ever be two software image files in the image table, the active and the inactive. Software image filenames have the following format: C-CC-R-(version number).img e.g. C-CC-R-7_1_4.img To upload a software image file; 1. Select Local > Maintenance > Upload > Software 2. Browse to the location of the file required to be uploaded into the terminal *.img. 3. Click on Upload. Software image files may take one or two minutes to upload as they can be quite large (≈ 2 Mbytes). The size of this file has caused some Microsoft Internet Explorer proxy server setups to abort during the software update process. To avoid this problem, either set the proxy file size limit to 'unlimited' or avoid the use of the proxy altogether. 4. Activate the image (see “Changing the status of an image file” on page 188). 5. Reboot the terminal using a ‘Hard Reboot’ (see “Rebooting the terminal” on page 189).
Maintenance | 186 Firmware image files Firmware image files contain instructions to configure the various programmable logic elements in the terminal. There can only ever be two firmware image files for the same HSC version in the image table, the active and the inactive. Firmware image filenames have the following format: C-fpga_Ef-x-y-z.img e.g. C-fpga_E5-0-6-4.img where f indicates the function (motherboard, interface card, etc). Function Number Function 1 Motherboard 1 2 Motherboard 2 5 QJET 7 Q4EM 8 DFXO 9 DFXS A Modem B QV24 C HSS where x indicates the HSC (hardware software compatibility) version. Revision Number Revision 0 revision A hardware 1 revision B hardware 2 revision C hardware 3 revision D hardware where y indicates the firmware major revision number where z indicates the firmware minor revision number To upload a firmware image file; 1. Select Local > Maintenance > Upload > Firmware 2. Browse to the location of the file required to be uploaded into the terminal *.img. 3. Click on Upload. 4. Activate the image (see “Changing the status of an image file” on page 188). 5. Reboot the terminal using a ‘Hard Reboot’ (see “Rebooting the terminal” on page 189).
Maintenance | 187 Viewing the image table To view the image table: 1. Select Link or Local or Remote > Maintenance > Image Table. The image table shows the following information: Heading Function Index A reference number for the image file Type The image is not currently being used by the system and could be deleted.

Inactive The image is not currently being used by the system and could be deleted.Selected The image is not currently being used by the system but has been activated and will become active following a terminal reboot. Current (deselected) The image is currently being used by the system but as another image has been selected, it will become inactive following a terminal reboot.
Maintenance | 189 Rebooting the terminal The local or remote terminals can be rebooted by SuperVisor. You can specify a ‘Soft Reboot’ which reboots the terminal without affecting traffic or a ‘Hard Reboot’ which reboots the terminal (similar to power cycling the terminal). You can specify an immediate reboot or setup a reboot to occur at a predetermined time. To reboot the terminal: 1. Select Link or Local or Remote > Maintenance > Reboot. 2. Select the Reboot Type field:  None: Do nothing.  Soft Reboot: Reboots the software but should not affect customer traffic.  Hard Reboot: Reboots the systems and affects customer traffic. 3. Select the Reboot Command field:  None: Do nothing.  Reboot Now: Execute the selected reboot now.  Timed Reboot: Set the Reboot Time field to execute the selected reboot at a later date and time. This feature can be used to schedule the resulting traffic outage for a time that has least customer impact.  Cancel Reboot: Cancel a timed reboot. 4. Click Apply to execute the reboot or Reset to restore the previous configuration.
Maintenance | 190 Support summary The support summary page lists key information about the terminal, for example, serial numbers, software version, frequencies and so on. To view the support summary: Select Link or Local or Remote > Maintenance > Support Summary.
Maintenance | 191 Installing interface cards Caution: You must power down the terminal before removing or installing interface cards. Interface cards are initially installed in the factory to the customers’ requirements however, during the life of the product, additional interface cards may need to be installed. Unless the terminals are protected (see "Protected terminals" on page 163), installing new interface cards involves a substantial interruption of traffic across the link. Staff performing this task must have the appropriate level of education and experience; it should not be attempted by inexperienced personnel. To install an interface card: 1. Switch off the power to the terminal. 2. Prepare the terminal for new interface cards (see “Preparing the terminal for new interface cards” on page 192). 3. Install the interface card (see “Installing an interface card” on page 194). 4. Power up the terminal. 5. Configure the slot (see “Configuring a slot” on page 196). A slot can be configured before installing a new interface card, or after the interface card is installed and the terminal power cycled. 6. Configure the cross connections. (see "Configuring the traffic cross connections" on page 133)
Maintenance | 192 Preparing the terminal for new interface cards To prepare the terminal for a new interface card: 1. Remove the terminal from service by first switching off the terminal power. For an AC powered terminal, remove the AC power connector. For a DC powered terminal, switch off the DC circuit breaker or supply fuse. 2. Remove all other cables from the terminal, marking their locations first, if necessary, to aid later restoration. The safety earth connection must be the last cable removed. 3. Ensure you have unobstructed access to the top and front of the terminal. Remove the terminal from the equipment rack, if required. 4. Remove the top cover of the terminal by removing two socket screws from the rear. Note: The top cover slides back towards the rear of the chassis. 5. Remove the front fascia by removing the four front panel socket screws. Note: The front fascia first hinges out to clear the antenna connector and earth stud, and is then removed by unclipping from the chassis and sliding downwards. See illustration below.
Maintenance | 193 6. Remove the card securing screw from the required interface slot. 7. There are two types of interface slot blanking plates, the seven tab break off and the single slot type (newer type). If the blanking plate is the seven tab break off, remove the slot blanking tab by folding the tab to and fro until it breaks off. If the blanking plate is the single slot type, unclip the blanking plate from behind the slot (assuming that the card securing screw has already been removed).
Maintenance | 194 Installing an interface card To install an interface card: 1. Remove the interface card from its packaging and static-safe bag. Caution: To avoid static damage to the terminal or the interface card being installed, use a static discharge wristband or similar antistatic device. 2. Offer the interface card into the chassis at an angle until the front panel of the card engages in the chassis. 3. Rotate the card in the chassis until it is level, and both parts of the card interface bus connector engage with the socket. Push down evenly on the interface card to seat it into the socket.
Maintenance | 195 4. Replace the card securing screw. Note: Some interface cards may not have the bracket to accept the card securing screw. 5. Replace the fascia and top covers, restore all cables, and power up the terminal.
Maintenance | 196 Configuring a slot 1. Select Link or Local or Remote > Interface > Slot Summary. 2. Select the required slot and click Configure Slot. 'Slot' shows the slot the interface card is plugged into in the terminal (A – H). Details of the interface card currently installed in the slot are: 'H/W’ (hardware revision). 'F/W’ (firmware revision) 'HSC’ (hardware software compatibility) A number used by the system software to determine which FPGA ‘firmware image file’ to use in the interface card installed. ‘Installed’ field shows the actual interface card installed in the slot. If there is no interface card installed in the slot, this field will show ‘none’. ‘Expected’ shows interface card type that had been previously installed. Interface cards can be setup before they are installed in the terminal or after they are installed in the terminal. 3. To setup a new interface card in a slot, select the interface card type you want to fit (or has been fitted) from the ‘Expected’ drop-down menu. Note: The transmitter, receiver and modem are configured in other sections (see "Configuring the terminal" on page 61). 4. Click Apply to apply changes or Reset to restore the previous configuration.
Troubleshooting | 197 14. Troubleshooting Loopbacks Loopbacks are used as a tool for testing or as part of the commissioning process and will affect customer traffic across the link. The terminal supports three types of loopbacks:  RF radio loopback  Interface loopbacks, set at the interface ports  Timeslot loopbacks RF radio loopback The RF radio loopback provides a loopback connection between the radio Tx and radio Rx. Each terminal is looped back independently. All traffic entering the transmit stage of the local terminal is turned around and delivered to the receiver section. This loopback will affect all traffic through the terminal. To enable or disable the RF loopback: Select Link or Local or Remote > Maintenance > Loopbacks.  To enable the RF loopback, click the RF Loopback checkbox (tick the box). Note: An RF loopback will automatically disable after the period set (in seconds) in the Loopback Timeout field. The default entry is 3600 seconds (60 minutes).  To disable the RF loopback, click the RF Loopback checkbox (untick the box). Click Apply to apply changes or Reset to restore the previous configuration. Note: When the RF loopback is selected, both the RX and TX LEDs will flash.
Troubleshooting | 198 Interface loopbacks The interface loopback provides a loopback connection for the customer-connected equipment. All traffic arriving from the customer interface is looped back. These loopbacks are applied on a port-by-port basis and can only be enabled on active ports i.e. has to be activated by assigning traffic to it by the Cross Connections application. The interface card green LED flashes while the loopback is active. Loopback type Description QJET (whole tributary) The QJET interface loopback will loop back the selected E1 / T1 port. QJET (individual timeslot) The Cross Connections application can loopback framed E1 / T1 timeslots (see "6Timeslot loopbacks” on page 198). Q4EM port The Q4EM interface loopback will loop back the port 4 wire analogue path to the customer. DFXO port The DFXO interface loopback will loop back the port digital paths to return the port analogue signal back to the customer. DFXS port The DFXS interface loopback will loop back the port digital paths to return the port analogue signal back to the customer. HSS port The HSS interface loopback will loop back the port data to the customer. QV24 port The QV24 interface loopback will loop back the port data to the customer. Ethernet No loopback possible. Timeslot loopbacks You can loopback framed E1 / T1 timeslots in the Cross Connections application. 1. Open the Cross Connections application. 2. Right-click the timeslot you want to loop back. 3. Select Timeslot Loopback - the looped timeslot will display in black:
Troubleshooting | 199 Alarms The LEDs (OK, RX, and TX) on the front panel illuminate either orange or red when there is a fault condition:  Orange indicates a minor alarm that should not affect traffic across the link.  Red indicates a major alarm condition that could affect traffic across the link. A major or minor alarm can be mapped to the external alarm outputs (see “Configuring the external alarm outputs” on page 76). Diagnosing alarms To view the Alarm Summary and their current states: Select Link or Local or Remote > Alarms > Summary.
Troubleshooting | 200 Alarm Explanation Synthesizer Status The selected transmit frequency is outside the tuning range of the transmitter synthesizer Modem Lock The terminal modem is not synchronized with the modem at the other end of the link TX Temp Shutdown The transmitter power amplifier temperature is greater than 75°C. The transmitter has shut down to prevent damage. TX Temp Warning The transmitter power amplifier temperature is greater than 70°C. The transmitter will continue to operate in this condition, but if the power amplifier temperature increases above 75°C, a major alarm condition is set and the transmitter will shut down to prevent further damage. TX AGC Voltage The transmitter power amplifier automatic gain control is out of limits for normal operation TX Reverse Power There is excessive reflected power at the transmitter port of the terminal, indicating a low return loss in the path between transmitter port and the antenna. TX Return Loss Status Indicates the difference between the transmitted power and the amount of power being reflected back into the terminal. The alarm will trigger when there is too much reflected power from the antenna that will degrade link performance. RX RSSI The RX RSSI alarm threshold is determined by the RSSI Thresholds for each of the modulation types (see “Configuring the RSSI alarm threshold” on page 73) Fan 1 The internal cooling fan 1 is not operating Fan 2 The internal cooling fan 2 is not operating External Input 1 -2 Indicates an active alarm state on the the external alarm input Alarm Output 1 - 4 Indicates an active alarm state on the the external alarm output MHSB Switch Indicates that the MHSB has switched over. The MHSB alarm is only shown if MHSB mode is enabled (see “Configuring the terminals for MHSB” on page 160). To view detailed alarm information: Select Link or Local or Remote > Alarms > Alarm Table The Alarm Table shows the source of the alarm and the type, the slot (and port, if applicable) where the alarm originated, the severity and the date and time the alarm occurred. To further diagnose the cause of the alarm (see “Identifying causes of alarms” on page 204, and “Alarm types” on page 229).

Select the desired interface card slot from the Interface Summary and click Alarms. This opens a page as shown below with a summary of the alarms on the interface card: The following fields are displayed:  Source: The type of interface card that generated the alarm  Type: The type of interface alarm  Slot: The slot of the interface card that generated the interface alarm  Port: The port that generated the interface alarm  Severity: Whether the interface alarm was major or minor 3. Return to the Interface Summary page by either selecting Options > Interface Summary or clicking Back in the browser window.
Troubleshooting | 203 Clearing alarms Select Link or Local or Remote > Alarms > Clear Alarms MHSB Command If a MHSB switchover event occurs, the OK LED on the front panel changes to orange. To clear the MHSB switchover alarm: Select Clear Switched Alarm from the MHSB Command drop-down list and click on Apply. Image Table Alarm An image table alarm appears if a problem occurred during the boot process which may have left the image table in an inconsistent state. To clear the two types of image table alarms:  The alternate image table alarm: this indicates that a backup image table has been used. This will match the actual image table unless immediately following a software upgrade.  The default image table alarm: this indicates that the image table has been rebuilt from defaults. In some circumstances this will mean that an incorrect build of software is running on the terminal. In either case, in addition to clearing the image table alarm, you should verify that the active images in the image table are correct for their software release.
Troubleshooting | 204 Identifying causes of alarms The following are possible causes of an alarm. LED Colour Possible causes OK Orange A minor system alarm is set Red A major system alarm is set RX Orange Low RSSI or AGC limits have been exceeded Red Receiver power supply or synthesizer failure TX Orange AGC, transmitter temperature, forward power or reverse power limits have been exceeded Red Transmit power supply or synthesizer failure OK LED Colour Alarm condition Suggested action Orange Fan failure Check that the fans are not blocked and can spin freely. Orange Interface card mismatch Using SuperVisor, check that the expected interface card and the fitted interface card are the same. Red Modem lock A modem lock alarm is generally seen when other conditions such as low RSSI are present. If there are no other alarms indicated, check the following: The terminal clocking is set up correctly. Both terminals are using the same modulation. Both terminals are using the same version of software. External RF Interference from equipment operating in adjacent channels. Check the constellation pattern for evidence of disturbances in the RF path. Compare RSSI with the expected values from the original path engineering calculation. Investigate any large differences. If the fault persists, contact your local representative. Red Interface alarms Check that the E1 or Ethernet interface cables are fitted correctly and the equipment they are connected to is functioning correctly.
Troubleshooting | 205 RX LED Colour Alarm condition Suggested action Orange Low RSSI Check that all antenna and feeder cables are firmly connected and not damaged or kinked Check there is no damage to the antenna Check the TX power and alarm status of the remote terminal Orange Receiver AGC Contact your local 4RF representative Red Receiver power supply Contact your local 4RF representative TX LED Colour Alarm condition Suggested action Orange Reverse power Check that all antenna and feeder cables are firmly connected and not damaged or kinked Check there is no damage to the antenna Check that the Receiver and Transmitter ports are correctly connected to the High and Low ports of the duplexer Red Transmitter temperature Check operation of cooling fan or fans Ensure the air grills on the sides of the terminal are clear Ensure the ambient air temperature around the equipment is less than 50˚C
Troubleshooting | 206 E1 / T1 alarm conditions The QJET interface yellow LED indicates:  Loss of signal (LOS) A loss of signal alarm occurs when there is no valid G.703 signal at the E1 / T1 interface RX input from the downstream system. This alarm masks the LOF and AIS received alarms.  Loss Of Frame alignment (LOF) A loss of frame alignment alarm occurs when the E1 / T1 interface RX input receives a valid G.703 signal (code and frequency) but does not receive a valid G.704 signal i.e. no frame alignment word, from the downstream system (in framed E1 / T1 modes only) (red alarm in framed T1 modes). This alarm masks the AIS received alarm.  Alarm Indication Signal (AIS) An AIS received alarm occurs when AIS is received from the downstream system. An E1 / T1 interface will output AIS to the downstream system if the normal upstream traffic signal is not available e.g. loss of modem synchronization, loss of RF signal across the link (blue alarm in framed T1 modes).  Remote Alarm Indicator (RAI) A remote alarm indicator occurs when RAI is received from the downstream system when it has an active LOS or LOF alarm (TS0 NFAS bit 3 in framed E1 modes and yellow alarm in framed T1 modes).  TS16 Loss of signal (TS16LOS) A TS16 loss of signal alarm occurs when there is no valid TS16 signal at the E1 interface RX input from the downstream system (in E1 PCM 30 modes only).  TS16 Remote Multi-frame Alarm Indicator (RMAI) A remote multiframe alarm indicator occurs when RMAI is received from the downstream system when it has an active TS16LOS alarm (TS16 F0 bit 6 in E1 PCM 30 modes only).  TS16 Alarm Indication Signal (TS16AIS) A TS16 Alarm Indication Signal alarm occurs when AIS is received from the downstream system in TS16. An E1 interface will output the TS16 AIS signal to the downstream system if the normal TS16 multi-frame signal is not available (in E1 PCM 30 modes only). The QJET interface green LED indicates: The QJET interface green LED flashes when the E1 / T1 port loopback is active.
Troubleshooting | 207 System log SuperVisor automatically keeps a log, known as 'syslog', which captures all alarms, errors and events for each terminal. You can specify that the ‘syslog’ is saved to a particular file (see "6Setting up for remote logging” on page 209). You can then email this file to customer service, if requested, to enable them to fault-find more accurately. Checking the syslog To view the Syslog: 1. Select Local > Performance > Logging > Syslog. This opens a new window:
Troubleshooting | 208 2. The system log is quite hard to decipher in Internet Explorer. If you're using Internet Explorer, select View > Source, which opens the file in a more legible layout in Notepad (see illustration below). Save or print this file, as required. 3. If you want to save the system log, you can save it from within Notepad (or Internet Explorer). Select File > Save As. Navigate to where you want to save the file. Enter a meaningful filename and select 'Text File' from the Save As Type drop-down list. Click Save. You can specify that this file is automatically saved to a computer (see "6Setting up for remote logging” on page 209).
Troubleshooting | 209 Setting up for remote logging Note: When setting up to save the system log to a specific computer, be aware that the file is constantly updated and may get quite large quite quickly. To set up a terminal for remote logging: 1. Copy the TFTP server application (tftpd32.exe, which is located in the TFTPD directory) from the terminal product CD into a suitable directory on the PC (for example, C:\Program Files\TFTP Server). 2. Create another directory where you want the system logs to be saved for example; C:\Aprisa XE Syslog 3. Double-click tftpd32.exe. 4. Click Settings and make sure that both ‘Syslog Server’ and ‘Save syslog message’ boxes are ticked. 5. Click Browse and select a directory where you want the Syslog file to be saved (created in step 2). 6. Click OK to close the Settings dialog box.
Troubleshooting | 210 7. In SuperVisor, select Link or Link or Local or Remote > Terminal > Advanced. 8. In the Remote Syslog Address field, enter the IP address of the PC on which the Syslog server is running. 9. In the Remote Syslog Port field, enter 514. 10. Reboot the terminal (Link or Local or Remote > Maintenance > Reboot). 11. Open the directory where the system logs are being saved to. You should see a file called syslog.txt.

Product end of life | 255 19. Product end of life End-of-life recycling programme (WEEE) The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment. Under the Directive, used equipment must be marked, collected separately, and disposed of properly. 4RF Communications has implemented an end-of-life recycling programme to manage the reuse, recycling, and recovery of waste in an environmentally safe manner using processes that comply with the WEEE Directive (EU Waste Electrical and Electronic Equipment 2002/96/EC). The WEEE symbol explained This symbol appears on Electrical and Electronic Equipment (EEE) as part of the WEEE (Waste EEE) directive. It means that the EEE may contain hazardous substances and must not be thrown away with municipal or other waste. WEEE must be collected separately You must not dispose of electrical and electronic waste with municipal and other waste. You must separate it from other waste and recycling so that it can be easily collected by the proper regional WEEE collection system in your area. Return and collection programmes in your area Contact your local or regional authority for information about the return and collection programmes available in your area. Your role in the recovery of WEEE By separately collecting and properly disposing of WEEE, you are helping to reduce the amount of WEEE that enters the waste stream. One of the aims of the WEEE directive is to divert EEE away from landfill and encourage recycling. Recycling EEE means that valuable resources such as metals and other materials (which require energy to source and manufacture) are not wasted. Also, the pollution associated with accessing new materials and manufacturing new products is reduced. EEE waste impacts the environment and health Electrical and electronic equipment (EEE) contains hazardous substances which have potential effects on the environment and human health. If you want environmental information on the Aprisa XE terminal, contact us (on page 15).
