U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless PLEASE READ THESE SAFETY PRECAUTIONS! RF Energy Health Hazard The radio equipment described in this guide uses radio frequency transmitters. Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard. Do not allow people to come in within 20cm to the front of the antenna while the transmitter is operating. Protection from Lightning Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building. The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode. FCC Notice, USA The AB-Access units comply with Part 15 of the FCC rules. Operation is subject to the following two conditions: • This device may not cause harmful interference. • This device must accept any interference received including interference that may cause undesired operation.

U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 2 Document Overview This document covers technical specifications and configuration information for the AB-Access system. It also covers some general troubleshooting steps to resolve issues that may occur while configuring or deploying the AB-Access system. This document should only be used as a reference for the 5.1.6 EMS and 5.1.5 or newer System Software. March 10, 2003 Company Confidential Page 11 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 3 AB-Access Overview 3.1 Topologies There are three topologies that are available with the AB-Access units CLIP, 1483 Bridging, and Native ATM. There are several configuration variations within these topologies but all will be referred by these names with an extension. 3.1.1 CLIP (RFC 1577) CLIP stands for Classical IP and is a routed topology. The AP or SU acts as a standard Layer 3 IP router, which means when data comes into the unit it analyzes the IP header and sends it out one of its interfaces based on the information in the header and its routing tables. It is important to note that only IP traffic can be passed over the units in this configuration. 3.1.2 1483 Bridging (RFC 1483) 1483 Bridging is a Layer 2 bridge, which will pass any valid Ethernet frame regardless of protocol. 1483 is also referred to as MPoA (Multi-protocol over ATM). The basic concept of how the bridge works is simple. It has two tables one for the terrestrial interface and one for the wireless interface. The terrestrial table stores all source MAC address it has learned from the terrestrial interface. It learns the MAC addresses by storing the source MAC address of any packet that has originated from a device on its terrestrial interface. If a packet is received that has a destination MAC address that is already in the table it will be discarded. The reason for this is if the destination MAC address is in the table it must mean that the device with that MAC address is on the terrestrial side of the radio. The wireless table works in the same manor except it learns the source MAC address of packets that have been received from the wireless interface. It is important to note that all broadcast packets will be sent over the link. It is also important to note that the implementation of 1483 bridging that the AB-Access system uses is LLC/SNAP encapsulation and we do not support the VC multiplexing implementation. 3.1.3 Native ATM Native ATM is a mode where both the AP and the SU act as an ATM switch. In this mode ATM cells are simply passed through the switching layer of the radio at layer 2.

Depending upon the required architecture, certain layers of this model may or may not be used. Please note that both the wireless and terrestrial interfaces have access to all of the functions of the unit. This is designed to allow the reader to understand where an incoming service is terminating and where its configuration is managed. Management files (on Flashfs) for each layer are as follows: All: system.conf Routing Layer: resolve Bridging Layer: resolve, initbridge, initmr1483 or initr1483 Switching Layer: initswitchcli An E or A will indicate the Terrestrial interface type below the interface at the corner. As an example, the diagram above shows an SU (on the left) with an Ethernet terrestrial interface and an AP (on the right) with an ATM interface. The Wireless interface is always ATM. Additional services/clients such as NAT and/or DHCP will be depicted at the appropriate interface. March 10, 2003 Company Confidential Page 13 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 4.1 Subnetting Subnetting within the AB-Access radios is done in hexadecimal format. There for it is necessary to know the decimal to hex conversions for commonly used subnets. CIDR notation is also used to define the subnets in all the diagrams, so refer to the chart below for any questions on subnetting. Decimal Subnet HEX Subnet CIDR 0 00 /24 128 80 /25 192 C0 /26 224 E0 /27 240 F0 /28 248 F8 /29 252 FC /30 4.2 Peak Cell Rate - PCR The Peak Cell Rate is policing not pacing, there for it will discard all cells received over the limit and not buffer them. This means the cells will be have to be retransmitted via an upper layer protocol. To calculate the Peak Cell Rate you simply divide the desired bandwidth by the number of bits in an ATM cell. An ATM cell is 53 bytes consisting of a 5-byte header and a 48-byte payload. In the following example, the PCR for a 1 Megabit circuit is calculated. PCR values are rounded to the nearest integer. 1024000 bps/(48 bytes-per-cell*8 bits-per-byte) = 2667 The following table lists PCR values for several, common data rates.

Here are a few important points that should be kept in mind if the AP doesn’t register. 1. See if you can ping the unit. The default configuration is to have the AP receive a DHCP address from the CS. If it has not received it you will not be able to ping it. So if you are unable to ping the AP you should check and see that the dhcpd.conf file is setup properly. Notice that in the example AP1 has a fixed address set, each AP must be given the same address every March 10, 2003 Company Confidential Page 35 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless time it leases an address. It is important to be aware that by default most routers will not pass DHCP request unless they are specifically configured to do so. #eth0 subnet 192.168.2.0 netmask 255.255.255.224 { range 192.168.2.34 192.168.2.50; option routers 192.168.2.33; } host AP1 { hardware ethernet 0:c0:69:0c:52:2f; fixed-address 192.168.2.50; } For various reasons it may be desired to not use DHCP to give an AP an address. In this case the IP address can be statically assigned to the unit. To do this you will need to create a resolve file that looks identical to the CLIP_T static resolve file described in the section for Static 1483_T. 2. Make sure the MAC address is correct. Without the correct MAC address the AP can not register. You can verify this by tailing the adapcs.log file. In this example an SU with the indicated MAC address is trying to register and is not found in the database. Either the SU was not added to the EMS or was entered with the wrong MAC address.

If the CS is on a different network, than the default route in the AP must be correct. 6.1.2.2 SU Object If the SU will not register make sure all the fields in the EMS database are filled in properly. Here are a few important points that should be kept in mind if the SU doesn’t register. Many different things can cause the SU not to register so after verifying all of these points and it still doesn’t register the next step will be to troubleshoot the RF link. See RF troubleshooting document. 1. Make sure the MAC address is correct. Without the correct MAC address the AP can not register. You can verify this by tailing the adapcs.log file. In this example an SU with this MAC address is trying to register and is not found in the database, which means when you created the object it had the wrong MAC address.

U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 6.2.3 Troubleshooting 6.2.3.1 Can’t ping the radio from the terrestrial interface 1. Check all physical connections. The radio is a network device, which means if you connect it to a PC (NIC) you will use a straight-through cable. To connect the radio to a network device (hub, switch, router) use an Ethernet cross-over cable (1-3, 2-6). It is also important to check that the cable is punched down correctly in the wall box and that the cable is terminated correctly at the radio. The termination at the radio uses 568B (wo,o,wg,bl,wbl,g,wbr,br). 2. Make sure the computer you are pinging from is on the same network as the AP. If you are on a different network than the radio make sure you have the proper routes in the radio and the computer you are trying to ping from. 6.2.3.2 Can’t ping across the wireless link There are numerous reason why you couldn’t ping across the wireless link. After following these troubleshooting steps and you still can’t ping across the wireless link refer to the RF troubleshooting document. 1.

This means that the AP will pass ATM cells at layer 2, and the SU will act as a router analyzing all data at layer 3 and based upon destination IP address forward the data out the proper interface. In static mode you can configure the management traffic in either routed or a switched configuration.

U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 1. Make sure the MAC address is correct. Without the correct MAC address the AP can not register. You can verify what MAC address the AP is attempting to register with by tailing the adapcs.log file. In the following example an AP is trying to register and is not found in the database, which means when you created the object it had the wrong MAC address. [root@cs1 /root]# tail -f /var/log/adapcs.log CS[5025.8192](16Dec 12:36:03.027 ): AtmAccessPointImpl: Unknown ATM AP 00c0690c522f trying to register 2. The management address must be on the same subnet as the atm0 interface on the Control Server. 3. Check that the PVCs are mapped correctly in the switch. Since the problem is with the AP registering, pay close attention to how the registration PVC (61) and management PVC are mapped.

The “AS Port” has to be filled in with the proper port if you have chosen to manage the anchor switch with the EMS (selected when creating the Control Server). 5. Make sure the Control Server has the created the proper atmarp entries in it. There should be an atmarp entry for every management address. • Lists atmarp entries [root@cs1 /root]# atmarp -a ----- Itf 0 (192.168.2.1, netmask 255.255.255.0) ----- Default QOS: ubr,aal5:max_sdu=9188 IP 192.168.2.50, state VALID, addr <none>, flags 0x4<PERM> 0.0.33 ----- Unknown incoming connections ----- ----- Incoming unidirectional connections ----- ----- End of dump ----- 7.1.2.2 SU Object If the SU will not register make sure all the fields in the EMS database are filled in properly.

It is also important to check that the cable is punched down correctly in the wall box and the cable is terminated correctly at the radio. The termination at the radio uses 568B (wo,o,wg,bl,wbl,g,wbr,br). 2. Make sure the computer you are pinging from is on the same network as the AP.

U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 9 1483_T The 1483_T configuration is where both the AP and the SU act as a layer 2 bridge. It is important to understand that in this configuration data can only go from SU-AP & AP-SU within the sector. Data will not be able to from SU-SU within the same sector. This can only be done by connecting a router to the AP and redirecting that traffic back to the AP. 9.1 Interactive 1483_T All assumptions for troubleshooting 1483_T are based on the following diagram.

U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 9.1.2 Troubleshooting 9.1.2.1 AP Object If the AP will not register make sure all the fields in the EMS database are correctly filled in. Here are a few important points that should be kept in mind if the AP doesn’t register. 1. See if you can ping the unit. The default configuration is to have the AP receive a DHCP address from the CS. If it has not received it you will not be able to ping it. So if you are unable to ping the AP you should check and see that the dhcpd.conf file is setup properly. Notice that in the example AP1 has a fixed address set, each AP must be given the same address every time it leases an address. It is important to be aware that by default most routers will not pass DHCP request unless they are specifically configured to do so. March 10, 2003 Company Confidential Page 84 of 149

In this case the IP address can be statically assigned to the unit. To do this you will need to create a resolve file that looks identical to the 1483_T static resolve file described in the section for Static 1483_T. 2. Make sure the MAC address is correct. Without the correct MAC address the AP can not register. You can verify this by tailing the adapcs.log file. In this example an SU with the indicated MAC address is trying to register and is not found in the database. Either the SU was not added to the EMS or was entered with the wrong MAC address.

U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 13 RF Design and Planning 13.1 Overview The AB-Access system is a communications system using wireless technology in the U-NII & ISM frequency bands. Therefore understanding Radio Frequency (RF) system design is necessary to ensure gook link quality and, thus, good system performance. This section discusses the basics of RF Design and Planning from the perspective of deploying the AB-Access System. 13.2 The U-NII & ISM Channel Plan In 1997 the FCC amended its Part 15 rules to make 300 MHz of spectrum available for high-speed wireless digital communications with unlicensed operation. This band, called the Unlicensed National Information Infrastructure or U-NII band, provides the spectrum at 5.15 to 5.25 GHz for indoor use, and 5.25 to 5.35 and 5.725 to 5.825 GHz for outdoor use. The peak output power permitted is limited to 23 dBm EIRP in the lower (indoor) band, 30 dBm in the mid-band, and 36 dBm in the upper band. The 5.8 GHz ISM (Industrial Scientific and Medical) band ranges from 5.725-5.850 GHz. Which is an unlicensed frequency limited to 36 dBm for PTMP equipment. The limit for PTP is higher than PTMP. NOTE: AB-Access uses both the U-NII and ISM band for its upper band channels. NOTE: BPSK modulation is only approved by the FCC for the upper band channels. 13.3 Air Interface The SU talks to the AP over a proprietary airlink protocol on a single 15 MHz channel using QPSK or BPSK modulation and a technique called Time Division Duplex (TDD). Both upstream and downstream traffic time-share this channel. 13.4 Wireless MAC March 10, 2003 Company Confidential Page 128 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless When data is sent over the wireless link it must first be put into a structure that each end unit will understand. The hardware that does this is called the MAC (Medium Access Controller). ASUSUSUACFRAC Cell Cell down-stream up-stream R---Cell Cell- idlidlVariable length MAC RGFDHDR DACK DCELLATT STT RR UACK UCELL/UCELLR 13.4.1 Downstream burst 13.4.1.1 Access Point Turnaround Time (ATT) AB-Access system is TDD (Time Division Duplexing), meaning that the AP and SUs transmit and receive on the same frequency. It is therefore necessary to have a small delay between the transmit and receive processes, because it is using the same hardware to perform both functions. 13.4.1.2 Frame Descriptor Header (FDHDR) Downstream bursts begin with a Frame Descriptor Header (FDHDR) this portion of the MAC frame is seen by all SUs in that sector. The FDHDR contains a map of all traffic upstream and downstream, to occur within the MAC frame. This is why you assign a unit a MID, when an SU sees an FDHDR it looks for its MID in the FDHDR to see if it is going to receive any cells. If it does not see its MID it will ignore the rest of the frame. 13.4.1.3 Reservation Grant (RG) The next field in the downstream burst is the Reservation Grant Response (RGR). An RGR is a response to an Reservation Grant Request (Upstream Burst). The RGR acknowledges a request and tells the SU that it can transmit on the upstream burst. March 10, 2003 Company Confidential Page 129 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 13.4.1.4 Downstream Acknowledgement (DACK) The Downstream Acknowledgement (DACK) is an acknowledgement sent from the AP, which contains bit maps corresponding to the success or failure of individual cells sent to an SU in the previous frame. If any cells were missed or dropped they will be resent in the next frame. 13.4.1.5 Downstream Data Cells (DCELL) The Data Cells are the actual ATM cells that contain data. The maximum ATM cells per frame are 32. The maximum ATM cells that can be sent to an individual SU is 6 per frame. 13.4.1.6 Subscriber Turnaround Time (STT) AB-Access system is TDD (Time Division Duplexing), meaning that the AP and SUs transmit and receive on the same frequency. It is therefore necessary to have a small delay between transmit and receive processes, because it is using the same hardware to perform both functions. There is also a set delay for each individual SU. This delay in turnaround is to compensate for propagation delay. 13.4.1.7 Reservation Request (RR) The Reservation Grant Request (RR) is a request sent by the SU to the AP when it has data to send. The RGR is a contention based request, meaning it performs like an Ethernet network were there is no guarantee that it will be received by the AP on the first try. This would happen when another SU wants to transmit at the same time and would cause a collision. If a collision occurs the SU will try again until it is acknowledged with a Reservation Grant Response. 13.4.1.8 Upstream Acknowledgement (UACK) The Upstream Acknowledgement (UACK) contains bit maps corresponding to the success or failure of individual cells from an AP. If any cells were missed or dropped they will be resent in the next frame. 13.4.1.9 Upstream Cell (UCELL/UCELLR) The UCELL’s are the actual ATM cells that contain data. The maximum ATM cells per frame are 32. The maximum ATM cells that can be sent to an AP by an individual SU is 6 per frame. The UCELLR is a data cell that also has a Reservation Grant Request if the SU has more than 6 data cells to send. The reason for this is so that the SU doesn’t have to contend for another Reservation Grant in the contention slot. 13.5 Delay Compensation During the upstream portion of the MAC several SUs transmit in sequence. Since SUs are separated from the AP by anywhere from 0m to 16km, there is a wide range of propagation times for the full path for the AP to the SUs and back. In order for the SUs transmissions to March 10, 2003 Company Confidential Page 130 of 149

An SU must delay compensate before it can transmit data, if it was allowed to transmit without delay compensating it would confuse the AP because it would be receiving cells out of order.

The AB-Access implementation of the TDD architecture allows the TDD frame to dynamically vary in size according to the offered load: short frames when fewer users are sharing the channel, longer frames when there are many simultaneous users. The TDD guard time is also adaptive, as it is set to round trip propagation delay to the farthest SU. TDD has a number of advantages over a FDD system. These include: • Spectral Efficiency – TDD can be deployed using less spectrum than a comparable FDD system. A single TDD channel can be deployed per sector instead of two channels needed for FDD. Likewise, a multi-cell deployment can be installed using a total of three RF channels (both polarizations), whereas FDD needs four to six channels. • Complexity – Since each transceiver is wither transmitting or receiving, but never both at once, a single RF front end can be shared reducing the radio complexity. • Power Control – In cellular systems, where channels are reused many times throughout the system in order to increase capacity, the highest efficiency is realized when the power in each direction can be minimized. This reduces the amount of March 10, 2003 Company Confidential Page 132 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless energy that is ‘leaked’ into surrounding areas, which appears as interference. In FDD systems, it is quite difficult to accurately control the channel’s power since a feedback path is required. No such path is needed in a TDD system since the same channel is used in both directions. The SU needs to only measure the received power from the AP in order to know how much to attenuate its upstream transmission. • Channel Efficiency – Because each frame carries upstream and downstream traffic in proportion to the offered load in each direction, adaptive TDD systems are highly efficient in its use of bandwidth. FDD systems have to make an estimate of the traffic mixture and allocate channel bandwidth accordingly. As shown in the chart below, any variation from this estimate (in this case 15:1 downlink) will result in wasted bandwidth. This variation is inevitable due to the diurnal variation of business usage during the daytime hours, residential usage in the afternoon and evening, a varying mixture of user types according to the geographic location, and an ever-changing set of user applications. 13.8 AP and SU Specifications 13.8.1 AP/SU/Extender Functional Block Diagram The Access Point and Subscriber Unit functional block diagram is shown below.

While the real world possibilities are endless, the following three distinctive geographic topologies will be covered: • Macrocells • Microcells • Picocells A Macrocell design should be used when you are trying to provide ubiquitous coverage over a large area. Each cell has many Subscribers. The fundamental limit in deploying in this manner is usually coverage zone (cell radius) due to U-NII & ISM EIRP limits, as well as building and terrain obstructions. A Microcell is normally used when you are trying to provide high density coverage to a smaller geographic area. Each cell sector has many subscribers per sector. The fundamental limit in deploying in this manner is co-channel interference due to LOS interference paths. A Picocell design normally covers an extremely small geographic area such as a neighbourhood or a Multiple Dwelling Unit (MDU) complex. There are normally March 10, 2003 Company Confidential Page 138 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless many sectors and few subscribers per sector. The fundamental limit in deploying in this manner is Line of Sight (LOS) coverage. While the above are generalizations, they can be used effectively as a starting point for developing an RF plan for deployment. However, based upon the specifications of the AB-Access equipment, it is necessary to have some pre-defined RF coloring schemes. To better understand the benefits of different coloring schemes, a basic concept of interference types should be understood. 13.10 Interference Types There are four distinct types of interference that can occur in a cellular reuse pattern. Each unique in its geometry and imposes unique frequency reuse constraints. EFFECT INTERFERENCE TYPE Would affect only the one SU. Could affect other units if they are in the same area. Type 1 – Downlink Downlink to Subscriber Unit Interfered with by another Access Point transmission. Would affect only the one SU. Could affect other units if they are in the same area. Type 2 – Downlink Downlink to Subscriber Unit Interfered with by a Subscriber Unit Uplink in another cell. Would affect all units in the sector. This would be a constant source of interference. Type 3 – Uplink Uplink to Access Point Interfered with by another Access Point transmission. Becomes critical if facets using same frequency face each other. Would affect all units in the sector. Could be an intermittent problem based on the amount of data that interfering SU is transmitting. Type 4 – Uplink Uplink to Access Point Interfered with by a Subscriber Unit uplink from another cell. Hardest to eliminate and will reduce the performance of the whole system. March 10, 2003 Company Confidential Page 139 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 13.10.1 Type 1 Interference Downlink to Subscriber Unit interfered with by another Access Point Downlink. All Access Points power control for full service at the sector edge (in cusp). The worst case scenario is when the SU (Cell 1) has the interfering AP at Boresight (Cell 2) and is towards the edge of its sector, i.e. min CNR from its AP. Interference Interfering APCell 1 Cell 2 Strong Interference path Weak Interference path Cell 2 Cell 1 13.10.2 Type 2 Interference Downlink to Subscriber Unit interfered with by a Subscriber Unit Uplink in another cell. Worst case scenario is interfering SU at range (max Tx power), and victim SU at range (lowest CNR) and SUs facing each other, e.g. Cells 1 and 3. The interference is reduced if SUs using the same frequencies do not face each other, e.g., Cells 1 and 2. Cell 3 March 10, 2003 Company Confidential Page 140 of 149
U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 13.10.3 Type 3 Interference Uplink to Access Point interfered with by another Access Point Downlink. This is only an issue if sectors using the same frequency face each other in the reuse pattern, e.g., Cell 1 and Cell 3. Otherwise it is a benign interference type, e.g., Cell 1 and Cell 2. Interfering AP Cell 3Interferencepath Interfering AP Cell 2Cell 1 13.10.4 Type 4 Interference Uplink to Access Point interfered with by a Subscriber Unit Uplink in another cell. This is the worst case of intercell interference, as one SU, e.g., in Cell 2, interferes with all the users on the same frequency and polarization in Cell 1 (whenever the SU in Cell 2 is transmitting). As the system has power control for SUs, the worst case Type 4 interference will be caused by SUs deployed at range and at the edge of their sector, i.e., in the Access Point Antenna Cusp.

U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 15 Rupee There are configurations that are not covered by the upgrade scripts. Even if they are covered, you will probably want to add settings that are specific to your network. To do this you can edit the individual files and rupee them to the units. This is not meant to replace the upgrade script. It is only meant to send individual configuration files to a unit. You can send individual files from DOS or LINUX; unlike the upgrade scripts. The reason for this is that the upgrade script is using expect scripting and can only be run from a Unix based OS. One note about the rupee-dos is that it can only be run be a true DOS based OS (Win95 or Win98 not NT). NT uses a Virtual DOS Machine (NTVDM) and will not work with the rupee-dos command. WARNING If you rupee a file or files to a unit and do not reboot the unit, and then rupee another file or files to the unit only the last set of files will be saved to the flash. 15.1 LINUX 1. Make sure you can ping the unit that you want to send files to. 2. Change to the directory that the configuration files are in. The rupee-unix file must also reside in this directory. 3. To upload individual files: ./rupee-unix –p atmos –d 2 –r <IP Address> <file> <file> Note: You might have to change the permissions on the rupee-unix command using “chmod” chmod +x ./rupee-unix 15.2 DOS 1. Make sure you can ping the unit that you want to send files to. 2. Change to the directory that the configuration files are in. The rupee-unix file must also reside in this directory. 3.

U-NII Config & User Guide 5.2 Axxcelera Broadband Wireless 16 RTFD (Return To Factory Default) The new Return To Factory Default (RTFD) feature allows IP connectiviey to be established with units that have unknown or invalid configurations. Using this feature, the AB-Access unit wil adopt a known IP configuration enabling Command Line Interface access via telnet through the physical Ethernet interface. Following a restart or power up, the AB-Access/AB-Extender units will listen for 1 second for a proprietary coded UDP packet on their Ethernet interface; adopting the appropriate IP configurations as indicated below. If the unit receives the UDP packet, it will retain the active configuration for 30 minutes, after which the normal start-up procedures will continue with the IP and interface configuration taken from the unit’s Flash files. If during the 30 minute period, a subsequent coded UDP packet is received, the timeout will be restarted. NOTE On Windows 2K and XP you may need to disable the auto media sense. Some NICs will be capable of disabling this feature from their configuration parameters. If this option is not available on your NIC you will have to add a registry entry. Axxcelera has created a reg edit that can be installed by simply double clicking on the media-sense.reg file. Or you can enter the following register key via regedit. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters] "DisableDHCPMediaSense"=dword:00000001 16.1 RTFD IP Configurations Ethernet Interface Access: IP Address 192.168.3.254 Netmask 255.255.255.0 Default Route 192.168.3.1 16.2 Recover To supply the coded UDP packet the “recover” utility is provided with the system software in two forms. recover-dos.exe - For use with a DOS prompt under Microsoft Windows.

Connect a PC (Windows or Linux) to the wallbox of the unit, ensuring that there is appropriate connectivity at the physical and IP levels. 2. Start the recovery utility. A sequence of dots will be displayed to indicate successful network transmissions. [root@temp SU_TEMPLATE]# ./recover-unix ethernet SU/AP recovery client …………………………….. 3. Restart the AB-Access unit. 4. When the recover utility terminates, the AB-Access unit has been successfully configured and can be contacted over the physical interface via a telnet session. 5. It is best to do a full system upgrade after a unit has been recovered to a state that IP connectivity is regained. This will insure the unit will function properly once redeployed. 16.4 Disabling the RTFD Feature RTFD can be disabled by writing a file to flash with the name “no_rtfd”. The file must be a text file; i.e. only containing ASCII characters. A suggested first line for the file is “disable RTFD” – though the actual content of the file will not be referenced: only the presence or absence of the file is significant.
