ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 PRODUCT DESCRIPTION Overview The ARCXtend solution is a wireless point-to-multipoint plant extension solution supporting the wireless transmission of digitally modulated RF signals between a cable system operator’s coaxial cable plant and one or more customer sites. The solution consists of a Strand or Vertically Mounted Network Hub (Hub) and one or more Customer Premise Equipments (CPE). The Hub connects directly to the coaxial portion of cable plant using a standard power passing, passive tap or coupler and is line powered over coax using 60-90 Vac. The CPE is installed at the customer site, connects to a standard cable modem, and is powered locally using an AC power pack. Figure 2-1: ARCXtend Solution Architecture System Configuration Figure 2-2 details the elements of the ARCXtend solution provided by Arcwave (shaded) and provided by the cable operator: Copyright 2005 Arcwave, Inc. ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 Cable Plant PC POE AC Power Pack RJ-45 -20 dB Monitor F Type-2 Port F Type-1 60-90VAC and DOCSIS Signal Hub CPE Hub Mounting Kit CPE Mounting Kit DC Inserter LP Attenuator Cable Modem Provided by Arcwave Figure 2-2: ARCXtend Solution Elements Cable and Wireless Network Interfaces Frequency Mapping The Hub receives a digitally modulated RF signal in the range between 90 and 860 MHz to and up converts it to one of the six available wireless carriers in the range 5.8 GHz license-free band. The channel can be 64 QAM or 256 QAM and up to 6 MHz wide. The CPE receives the wireless signal and down converts it to an RF channel in the range 90 to 150 MHz which is provided to a Cable Modem. The CPE receives a digitally modulated RF signal in the range between 5 to 42 MHz and up converts it to a fixed frequency in the range 5.8 GHz license free band. The Hub receives the wireless signal and down converts it to the appropriate RF channel in the range 5 to 42 MHz. Signal Levels The Hub includes Automatic Gain Control (AGC) on the RF input and can accept an RF input signal of 0 to +30 dBmV while providing optimum wireless transmit power. The hub wireless transmitter power, determined by the Downstream Transmit Power setting, can be set for on of three modes: High, Medium or Test mode. Note: The “High” power setting is for use with the AX1455-SM-Network Hub. Use of the “High” power setting with the AX1455-SM-25 cancels the FCC certification and voids the user’s authority to operate the unit in the 5.8 GHz band. The upstream output power out of the Hub into the cable plant is controlled by the Upstream Attenuation parameter. This parameter is automatically set by the Hub based on the transmit power setting of the Embedded Cable Modem (ECM) contained in the Hub. Copyright 2005 Arcwave, Inc. ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 The gain of the CPE is fixed in both the upstream and downstream direction. The transmit power of the CPE directed towards the Hub will vary based on the input RF signal received from the cable modem. The CPE can accept an input RF signal between 20 and +58 dBmV from a cable modem. The downstream output power out of the CPE directed towards the cable modem will vary based on the distance between the Hub and the CPE. It is typically in the range of +10 to +30 dBmV. Arcwave provides specially designed low pass attenuators to reduce the downstream power level to within the – 15 dBmV and +15 dBmV operating range of a cable modem. Note that for 256 QAM the downstream power level into the cable modem must be at least -6 dBmV. Element Management Each Hub contains Arcwave’s ARCSmart intelligent network management which combines an embedded DOCSIS 2.0 compliant cable modem, SNMP-compliant Arcwave Enterprise MIB (management information base) and a processing engine with upgradeable software to support low cost configuration monitoring, and troubleshooting of a Hub. Management of the CPE can be most cost effectively achieved using the capabilities built into the subscriber cable modem. The CPE has no settable parameters so management is not required. Applications Copyright 2005 Arcwave, Inc. ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 ARCXtend Wireless Drop Figure 2-3: Wireless Drop ARCXtend can be deployed as a wireless drop connecting customers located across a parking lot, highway, or river or in areas with zoning restrictions to your plant. An AX1455-SM strand mount hub mounts directly on the cable plant. Wireless Overlay and Upstream The ARCXtend Wireless overlay solution delivers additional DOCSIS capacity without costly network upgrades or deployments. It is an ideal solution for providing DOCSIS-based services to isolated communities or out-of-franchise markets. A typical ARCXtend cell site, mounted on 100 foot tower, can cover over 100 square miles and could provide commercial-grade high speed data service for up to 1,600 customers. The ARCXtend Wireless upstream solution provides a quick and cost effective means for upgrading older one-way plants to deliver 2-way DOCSIS service. With the ARCXtend wireless upstream solution, two-way service can be up and running in weeks rather than months at a fraction of the cost of upgrading the entire plant. Copyright 2005 Arcwave, Inc. ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 Equipment Description ARCXtend Network Hub The Hub is a self-contained weather-protected unit providing a 2-way wireless connection between a CMTS or cable plant and a cable modem. The Network Hub includes an integrated transceiver, antenna, embedded cable modem and controller supporting high reliability point-tomultipoint wireless coverage, SNMP, HTTP-based web user interface, ARCSmart Intelligent network management, and PureBurst upstream ingress noise suppression technology. • • ARCSmart is a fully programmable and field upgradeable engine that enables a Network Hub to dynamically optimize itself to changing DOCSIS or Wireless Network conditions. PureBurst enables Cable MSO’s to send an upstream DOCSIS channel over wireless links with zero impact to their cable network. The Hub is frequency agile from 90 to 860 MHz and can be connected directly to a cable plant using a common tap or coupler. It can be mounted on the cable strand or on a tower, building or other nearby structure and can be line or locally powered.

ARCSmart firmware upgrade ARCSmart provides the ability to upgrade its firmware using a TFTP (Trivial File Transfer Protocol) protocol. This is accomplished using the Firmware Download Information table on the Arcwave MIB Maintenance page: TFTP server IP Address: Enter the TFTP (Trivial File Transfer Protocol) server’s IP address. Firmware Upgrade Filename: Enter the file name of the ARCSmart controller firmware to be downloaded to the Hub. Start Upgrade: Click the “Apply” button to initiate the download. The download of the new controller firmware will take one to two minutes. The download can be verified by refreshing the page. The version number of the downloaded firmware should be displayed in the Firmware Version Number box under in the Real Time Monitor Information table. Advanced Network Management Features Plug-n-Play ARCSmart has the ability to automatically program and modify Hub settings with the same DOCSIS downstream and upstream channel information being received by the ECM. To activate this feature, set Auto Frequency Set to “ENABLE”. With this activate, whenever the ECM detects a change in the downstream or upstream channel it will propagate this change to the appropriate Hub settings. This includes information sent in a Station Maintenance Message (SMM) Notification-US Frequency Change. Downstream frequency agility ARCSmart has the ability to automatically “tune” to a downstream channel on the cable network. To activate this feature, set Cable Interface Control to “On”. Settable Hub Transmit Power The wireless transmitter output of the Hub, determined by the Select Downstream Power setting, can be set for on of three modes: High (high power), Medium (high linearity) or Test (short range) Note: The “High” power setting is for use with the AX1455-SM-60 Network Hubs. Use of the “High” power setting with the AX1455-SM-25 cancels the FCC certification and voids the operator’s authority to operate the unit in the 5.8 GHz band. Copyright 2005 Arcwave, Inc. 12 ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 PureBurst Ingress Noise Suppression PureBurst effectively functions as a door. When there is no wireless upstream signal being received by the Hub, this door is closed. When closed, the Hub does not output any noise onto the cable plant. Therefore, when other subscribers are transmitting in the upstream to the CMTS, the wireless hub does not contribute to the cable plant’s noise floor. When a cable modem utilizing the wireless upstream link is transmitting the door is open. During this time the Hub allows the upstream signal plus Hub related thermal noise to pass onto the cable plant. Closing of the door results in the cable plant’s U/S noise floor returning to its previous level. This ensures that the only upstream signal affected by the hub’s internal upstream noise is the wireless burst signal as scheduled by the CMTS. This allows many wireless hubs employing PureBurst to be connected to the same cable plant without raising the upstream plant noise floor and affecting other users sharing the same cable plant. This feature is enabled by default.

An acceptable wireless link is one within the working range of Hub and with line of sight to the customer sites. Line of Site Line of sight is defined as a path between the Hub and CPE that is free of obstructions in the Fresnel zone. Obstructions could be trees, buildings, street signs, etc. An accepted rule of thumb is that LOS conditions exist when there are no physical obstructions within 60% of the Fresnel zone (obstruction free zone). Obstructions can be trees, buildings, street signs, etc. The Fresnel Zone clearance is determined by the distance between the Hub and CPE as shown in Figure 3-1. CPE Net work Fresnel Zone m ust Hub be clear of obstruct ions 500 ft. 1,000 ft. ½ mile 1 mile 2 miles 3 ft. 4 ft. 12 feet 6 ft. 9 ft. Figure 3-1: Fresnel Zone Clearance Requirement Range The maximum range, assuming a clear Fresnel zone, is determined by the Hub type, downstream modulation, and the mounting height of the Hub. The range, arc, and coverage area of all models of Hubs are given in Tables 3-1 and 3-2.

Draw two circles taking the customer site(s) to be covered as its center and the maximum range of each Hub type as the circle’s radius. . Once you have identified possible sites for the Hub, drive out to these locations and determine which, if any of them, provide a line of site path to the customer site(s) to be served. The simplest way to do this is, using a spotting scope, find the other end of the path and determine if it meets the Fresnel zone criteria. A more accurate approach would be to use a range finder to measure the height of the highest obstruction in the path and GPS to measure the distance. If you find that none of the Hub sites will work then you need to go back to the map and try and locate alternative locations. Checking for Upstream Interference ARCXtend maps the upstream DOCSIS channel to a frequency between 5,725 MHz and 5,742 MHz. As shown in Table 3-3 the mapping is fixed and based solely on the frequency of the upstream DOCSIS channel.

As part of the site selection process check for interference at the wireless frequency carrying the DOCSIS upstream channel. If interference is present you will need to use a different DOCSIS upstream channel, if possible, or move the Hub to a different location. . Handheld wireless LAN spectrum analyzers covering the 5.250 to 5.350 range and capable of identifying signals regardless of origin, like the BANTAM INSTRUMENTS Model 425A, are ideal for locating potential interference. CPE Site Selection Height and Location A suitable location for the CPE is one that provides an acceptable line of sight (LOS) wireless link, as previously defined, to the Hub. This requires the CPE to be placed high enough on the rooftop to provide the required Fresnel zone clearance. Using the setup shown in Figure 3-2, the optimal height and location can be determined by monitoring the Signal Level reading on the AR100 Signal Strength Meter. Monitoring the Signal Level meter on the AR100, the optimal CPE height and location will be indicated by maximum signal level readings. The CPE should be located to the edge of the building closet to the Hub. If the CPE were to be mounted towards the middle or back of the building, the incoming wireless signal can be reflected by the rooftop impairing the performance of the link. It is also advisable to select a location near to the rooftop grounding system to have a short, low resistance path and within 300 feet of an AC power source. The routing path for the coaxial cable that connects the CPE to the cable modem is also worked following your normal guidelines.

The available carriers and the corresponding CPE downstream RF channel are given in Table 3-4.

Note that the North American DOCSIS 64 QAM or 256 QAM downstream signal is 5.25 MHz wide and is transported within a standard 6 MHz wide channel throughout the CATV plant and the ARCXtend system.

At the time of installation the ARCXtend Hub is automatically configured to the CATV downstream channel. Any EIA channel between 7 and 134, inclusive, may be utilized. Table A-4 in Appendix A provides a list of these channels and their corresponding center frequencies. Copyright 2005 Arcwave, Inc. 17 ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 The Downstream DOCSIS channel can mapped to any one of the available downstream wireless frequencies. Each downstream wireless channel is down converted by the CPE to a fixed frequency as given in Table 3-4. e In summary, any CATV downstream channel may be employed as input into the Hub, and any specified air frequency between 5729 and 5843 MHz may be chosen, but the cable modem receive frequency (channel) is determined from the wireless frequency. Note that the downstream CATV frequency may be different than the cable modem receive frequency. This is generally not a concern as most DOCSIS systems on which there is only one DOCSIS downstream channel on the cable network do not specify the CM receive frequency in the CM configuration file, rather they let the CM find the downstream on its own. Upstream Configuration The ARCXtend upstream block diagram is illustrated in Figure 3-4. Note that the North American DOCSIS (Version 1.0 and 1.1) QPSK or QAM upstream signal is up to 3.2 MHz wide. DOCSIS 2.0 upstream signals can be as much as 6.4 MHz wide. All frequencies specified in this section are the center frequency of the particular signal.

Any upstream channel frequency between 10 and 42 MHz will work with ARCXtend. Referring to Figure 3-4 from right to left: The ARCXtend Subscriber Transceiver (CPE) up converts and transmits the entire cable upstream band. The Hub receives only the selected wireless upstream channel. The upstream wireless channel is centered at 5,720 MHz plus the upstream DOCSIS channel frequency: e.g. Upstream Channel 29.5 MHz is transmitted at 5,749.5 MHz. Copyright 2005 Arcwave, Inc. 18 ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 ARCXtend Multiple Hub Configurations Downstream If multiple ARCXtend Hubs are to be installed such that more than one Hub is visible (line of sight) from any ARCXtend subscriber transceiver (CPE), additional measures must be taken. A receiver will not operate properly if it “sees” signal on the same frequency from more than one transmitter such that the two or more signals arrive at the receiver at levels within approximately 25 dB of each other. (If the desired signal is greater than approximately 25 dB stronger than the undesired, the receiver will function). Since the ARCXtend downstream configuration can map the CATV plant downstream channel to any of the specified air frequencies, the solution is to choose different downstream air frequencies for each visible ARCXtend Hub. Upstream Similarly, if multiple ARCXtend Hubs are to be installed to cover a larger geographic area than can be accommodated by the antenna pattern of one Hub, but in close enough proximity that more than one Hub can “see” the upstream signal from a particular CPE operating at the same upstream air frequency then there must he at least 25 dB separation for 64 QAM and 30 dB separation for 256 QAM operation between the two CPE’s. If this signal separation can’t be achieved then you must use different DOCSIS upstream channels for each Hub. This means that each CM transmit frequency will be passed upstream into the CATV plant. IP Network Preparation Hub’s Default IP Address The ARCXtend Network Hub (Hub) utilizes an IP address in the cable network for remote management and automatic of configuration of Hub parameters. If an IP address is not provided for the Hub, it can be only accessed via the local Ethernet interface and using the default IP address: • • IP address of 192.168.100.1 Subnet mask 255.255.255.0 Cable Network IP Address If remote management or plug-n-play installation is desired, the Hub must be assigned an IP address by the cable network. This is accomplished by provisioning the MAC ID of the Hub’s embedded cable modem (ECM) MAC ID into the networks OSS/NMS. Copyright 2005 Arcwave, Inc. 19 ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 DHCP Server Setup The Hub’s ECM requires an IP address and its own unique configuration file. In order for the ECM to be assigned an IP address and be loaded with the proper configuration file the following actions are required: Set up a DHCP pool on your server for the ARCXtend ECMs to ensure that the ECM is properly configured and addressed. ECM Configuration File The ECM has its own DOCSIS standard format configuration file, ecm.cfg, which is pre-loaded at the factory and loaded on the ECM. A copy is also included on the documentation CD and downloadable from the customer support page of the www.arcwave.com web site. The configuration file should be edited prior to installation to confirm the cable network specific settings. The configuration file for the ARCXtend ECM contains the following information: • • • • • Downstream channel parameters (optional) UCD which specifies the upstream channel parameters (optional) Authentication parameters (optional) Registration parameters (mandatory) ECM firmware upgrade file name (optional) The Hub ECM and attached wireless subscriber cable modem must be assigned to the same upstream frequency and must not be part of an upstream group supporting multiple upstream channels. TCP/IP Port Filtering TCP/IP port filtering is the practice of selectively enabling or disabling Transmission Control Protocol (TCP) ports and User Datagram Protocol (UDP) ports on computers or network devices. The following ports must be open for SNMP, HTTP, and TFTP applications to be performed on the Hub: • • • Port 161/162 for SNMP Port 80 for HTTP Port 69 for TFTP Hub Electrical Interface The Hub is connected to the cable plant using a power-passing tap spliced in at the desired location on the cable plant. AC Powering and Surge Protection In strand mount applications, the Hub is powered through the input RF port. The Hub is capable of 60 Vac or 90 Vac plant power. The internal power supply provides a regulated 24 Vdc output Copyright 2005 Arcwave, Inc. 20 ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 over an ac input between 50 Vac and 110 Vac with a line frequency from 50 Hz through 60 Hz. A 20-ampere fuse is furnished in the power supply module and provides over current protection for ac power applied to the input. SCTE compliant surge protection is provided in the power supply. DC Powering The Hub can also be powered through the weather-protected Ethernet port using Power-overEthernet. The power level at the Ethernet Port should be between 18 and 26 Vdc. RF Signal Power Level and Quality The Hub requires a downstream path RF power level at the input RF port of between 0 dBmV and +30 dBmV. The modulation error ratio (MER) going at the input RF port should be within the budgeted range for the wireless link. In general a minimum MER of 35 dB is required for 256 QAM and 31 dB is required for 64 QAM downstream path modulations. CPE Electrical Interface The CPE is powered over and connects to the cable modem, using standard coaxial cable. AC Powering and Surge Protection The CPE is powered through the RF output port. The CPE is powered with 18 Vdc. Arcwave provides a 120 VAC CPE power pack and a power inserter approved for use with the CPE. The CPE must typically be located within 300 feet of the power pack to insure adequate powering of the CPE. Lightning Protection The CPE must be mounted at least 2 feet below the highest point at the site to minimize the likelihood of lightning strikes. The location should be properly grounded for lightning protection to all applicable national (National Electric Code, sections 820-33 and 820-40) and local codes. To protect the customer equipment from surges on the coaxial cable that is connecting the CPE to the cable modem, the installation of an SCTE compliant surge protector is required.

The Arcwave Enterprise MIB is included in all ARCXtend Network Hubs. The MIB file contains variables that can be set or read to provide information on network devices and interfaces. The Arcwave MIB is a set of variables that are private extensions to the Internet standard MIB II. The MIB II is documented in RFC 1213; Management Information Base for Network Management of TCP/IP based Internets: MIB-II. The listing of Arcwave MIB variables in the Arcwave.mib text file is identical to the listing of Arcwave MIB variables in this guide. The Arcwave.mib file is included on each product documentation CD and can also be obtained from Arcwave technical support. The Arcwave MIB variables are accessible via the Simple Network Management Protocol (SNMP), which is an application-layer protocol designed to facilitate the exchange of management information between network devices.

Copyright 2005 Arcwave, Inc. 69 ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1 Sequence Event Scan for a downstream channel and establish synchronization with the CMTS. Obtain upstream channel parameters. Start ranging for power adjustments. Establish IP connectivity. Establish the time of day. Establish security. Transfer operational parameters. Comply with baseline privacy. Enter the operational maintenance state. Description The cable modem acquires a downstream channel from the CMTS and saves the last operational frequency in non-volatile memory. The cable modem tries to reacquire the saved downstream channel the next time a request is made. Note An ideal downstream signal is one that synchronizes QAM symbol timing, FEC framing, MPEG packetization, and recognizes downstream sync MAC layer messages. The cable modem waits for an upstream channel descriptor (UCD) message from the CMTS. The UCD provides transmission parameters for the upstream channel. The ranging process adjusts the cable modem’s transmit power. The cable modem sends a DHCP request to obtain an IP address, which is needed for IP connectivity. The DHCP response also includes the name of a file that contains additional configuration parameters, the TFTP server’s address, and the Time of Day (TOD) server’s address. The cable modem accesses the TOD server for the current date and time, which is used to create time stamps for logged events (such as those displayed in the MAC log file). Keys for privacy are exchanged between the cable modem and the CMTS. After the DHCP and security operations are successful, the cable modem downloads operational parameters from a configuration file stored on the cable company’s TFTP server. If the software image running on the cable modem includes baseline privacy, link level encryption keys are exchanged between the CMTS and the cable modem. As soon as the cable modem has successfully completed above sequence, it enters operational maintenance state. Table B-1 Cable Modem Initialization Steps Copyright 2005 Arcwave, Inc. 70
