ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    2 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:

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.
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    4 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.

ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    5 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.

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.
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    13 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.
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    14 PRE-DEPLOYMENT PLANNING Hub Site Selection  A suitable location for the Hub is one that provides an acceptable line of sight (LOS) wireless link to the CPE(s) located at the customer site(s). 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.  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.

ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    16 Table 3-3: Upstream Channel Mapping 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.   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.  All downstream frequencies indicated are the center frequency of the 6 MHz wide channel. Figure 3-3:  ARCXtend Downstream Block Diagram Downstream Block Diagram The DOCSIS cable modem downstream channel on the CATV plant is already established in the working cable modem 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.
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    18 TapCATV PlantARCXtendSubscriberTransceiverCable ModemARCXtendHubTransceiverCATV UpstreamFrequency5 MHz - 42 MHzARCXtend Air Frequency5258 MHz - 5342 MHzCM TransmitFrequency5 MHz - 42 MHzLAN or USBThe 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. Figure 3-4:  ARCXtend Upstream Block Diagram Upstream Block Diagram The cable modem (CM) is commanded by the downstream signal to transmit at a specific upstream frequency between 10 MHz and 42 MHz. 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.
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    19 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.
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    20 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
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    21 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-over-Ethernet. 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.

Install as shown in Figure 4-1 per the steps provided below using a 7/16” combination or socket wrench. It is recommended that the hub be located on the strand as close as possible to the utility pole to minimize swaying in windy conditions.  1.  Attach the bracket to the messenger strand with the hanger bolts at A and B.  Tighten the hanger bolts lightly.  If the existing cable bundle lashed below the messenger strand
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    25 is sufficiently thick to interfere with the top of the Hub cover, the two elevation adjustment bolts D can be relocated to a pair of upper holes G on the back plate F. 2.  Loosen horizontal adjustment bolt C and rotate the hub so that it is pointed at the center of the area to be served by this hub.  Tighten azimuth adjustment bolt C. 3.  Loosen the two elevation adjustment bolts at D (one on each side of the mounting bracket) and tip the Hub back plate F so that it is parallel to the azimuth adjustment bolt C. Tighten the elevation adjustment bolts lightly.  4.  Loosen the hanger bolts A and B and slide them in the slots E at the top of the mounting bracket until the hub balances and the back plate F is perpendicular to the ground.  Tighten the hanger bolts A and B. 5.  Loosen the two elevation adjustment bolts at D (one on each side of the mounting bracket) and tip the hub up or down to point it at the center of the area to be served.  Tighten the two elevation adjustment bolts D. 6.  Ensure that all bolts are tightened securely.  7.  Using a 75 ohm F connector coaxial cable, connect the Hub to the power passing tap.  8.  This completes the physical installation of the Hub. Establish a Local Connection to the Hub )Connect a laptop computer to the RJ-45 Ethernet port of the Hub and connect to the Hub via an Internet Explorer 5.x or higher with the IP address set to 192.168.100.1.  Note: If your lap top Ethernet Port alternates between “connected” and “not connected” you should reconfigure its LAN port speed and duplex setting from Auto to 10Mbps.   The hub should respond with the “Enter Network Password” prompt.  Enter the “user id” and password. The default user id “admin” and password is “arcwave”.  Verify the Embedded Cable Modem has achieved operational maintenance state.  ) Referring  to the Cable Status page of the user interface: Verify that the Embedded Cable Modem has successfully completed its initialization sequence.  If it has not, troubleshoot per normal procedures. Set up and verify the Hub’s cable plant interface ) Referring  to the Arcwave MIB page of the user interface:  •  Verify that the Upstream Frequency and CATV EIA Input Channel settings are correct.  If Cable Interface Control and Automatic Frequency Set are enabled these values will be entered automatically based on the values being used by the ECM. You can override these values by disabling the Cable Interface Control and Automatic Frequency Set features and entering them manually,  •  Verify that DCE Lock is set to true.
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    26 Set up and verify the Hub’s wireless interface )Referring to the Arcwave MIB page of the user interface: •  Set the Downstream Air Frequency. •  Set Select Downstream Power level the appropriate setting: a.

Arcwave MIB Maintenance ARCXtend Id  Displays the Hub type, AX1455, AX1455 Standard Band (5.8 GHz), AX1455 Extended Band (5.8 GHz), AX1555 (future), AX1655 (Enhanced) and AX1755 (future). This parameter is used internally by ARCSmart to customize the user interface based on the Hub type.  Cable Interface Control  Chose “Enable” to turn-on the RF interface of the ECM and “Disable” to turn it off. This parameter is useful when the Hub is used for a non-DOCSIS application, such as the wireless transport of a digital video or CBR (constant bit rate) voice signal, and there is no DOCSIS channel on the cable plant.  Selecting the “Disable” setting will prevent the ECM from continually scanning for a downstream channel, when none is present. The default setting is “Enable”
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    48 When Cable Interface Control is set to “Disable”, Network Access is set to “Disable” and Upstream Attenuation can not be set to “99”, automatic mode.  Auto Frequency Set  Chose “ENABLE” to have ARCSmart automatically program the Hub CATV EIA Input Channel and Upstream Frequency parameters with the same values used by the ECM. When set to “ENABLE” these parameters will change whenever the values are changed at the ECM. This setting is used for plug-n-play installation of the Hub. Chose “Disable” when these parameters will be set manually to values different than those used by the ECM. In this mode, the values entered will persist regardless of the values used by the ECM and across a Hub power outage or reboot. This mode is useful when the Hub will transmit a non-DOCSIS channel, such as digital video or CBR voice.  The default setting is “Enable”. Note: “Cable Interface Control” must be set to “Enable” in order for this element to be set to “Enable”. Local Ethernet Interface  Chose “Enable” to allow local connection to the Hub via the RJ-45 connector. Chose “Disable” to disable the RJ-45 connection and prevent anyone from connecting locally to the Hub.  When Local Ethernet Interface is set to “Disable”, Network Access is also set to “Disable”. Network Access  Chose “Enable” to allow a locally connecting computer to obtain an IP address, via DHCP, from the head end server and to access the cable IP network.  Chose “Disable” to prevent a locally connected computer from accessing the cable IP network. The locally connected computer will be assigned a default IP address  in the 192.168.100.0/24 network. Select Upstream Band  Not used with AX1455.   Upstream Frequency  Displays the frequency of the upstream channel that is being received by the Hub.  CATV EIA Input Channel  Displays the EIA standard channel number of the downstream channel that is being received by the Hub.  Upstream Attenuation  Chose the amount of attenuation (in dB) in the upstream receive path of the Hub.   If “99” is entered, ARCSmart will automatically set the attenuation based on the upstream channel transmit power out of the ECM.  If a number in the valid range from 0 to 64 is entered, the attenuation is set to that value.  This parameter is used to increase or decrease the upstream
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    49 channel transmit power of a cable modem connected wirelessly to a Hub. Increasing the attenuation will cause the CMTS to increase the cable modem’s upstream channel transmit power. Decreasing the attenuation will cause the CMTS to decrease the cable modem’s upstream channel transmit power. The change in the attenuation and the change in the upstream channel transmit power, while loosely related, is not one to one. Note: “Cable Interface Control” must be set to “Enable” in order for this element to be set to “99” (Automatic Upstream Attenuation setting). Downstream Air Frequency  Chose the downstream wireless carrier frequency.  Valid settings for AX1455 model Hubs are: 5,813, 5,819, 5,825, 5,831, 5,837 and 5,843 (in MHz). Downstream Enable  Chose “TRUE” to turn on the downstream wireless transmitter and “False” to turn it off. The default setting is “False”. Upstream Enable  Chose “TRUE” to turn on the upstream wireless receiver and “FALSE” to turn it off. The default setting is “False”. Select Downstream Power  Chose the downstream wireless transmitter power setting: High, Medium or Test Alarm Mask  The alarm mask corresponds to the hex number, which when translated into a binary number gives an 8 digit number. The position of a digit ‘1’, in that number, would enable the corresponding alarm and a digit ‘0’ would disable the corresponding alarm.  All 0’s masks all alarms, all F’s lets all alarms through, individual alarms are respresented as follows:   Bit 0:  1 = System Lock Lost Bit 1:  1 = Hub Dead Bit 2:  1 = Input voltage outside of tolerance Bit 3:  1 = Downstream (Transmitter) Over Temperature Bit 4:  1 = DCE Unlocked or Error Bit 5:  1 = Upstream (Receiver) Unlocked or Error Bit 6:  1 = Downstream (Transmitter) Unlocked or Error Bit 7:  1 = Local modification notification Example: If the user wanted alarms “System Lock Lost, Input voltage outside of tolerance, DCE Unlocked or Error and Local Parameter Modification Notification” turned on & the rest turned off, he would have to set the alarm mask to 0095 (Hex), which corresponds to 10010101 (Binary).

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.

ARCXTEND USER MANUAL – R1.4, ISSUE 6 Copyright 2005 Arcwave, Inc.    69 CABLE MODEM INITIALIZATION The sequence numbers shown in Figure B-1 are explained in Table B-1, which appears after the illustration. The cable modem will complete all the steps in this flowchart each time it needs to reestablish ranging and registration with the CMTS.
ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1  Copyright 2005 Arcwave, Inc.    70  Sequence Event  Description 1 Scan for a downstream channel and establish synchronization with the CMTS. 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. 2  Obtain upstream channel parameters.  The cable modem waits for an upstream channel descriptor (UCD) message from the CMTS. The UCD provides transmission parameters for the upstream channel. 3  Start ranging for power adjustments. The ranging process adjusts the cable modem’s transmit power.  4  Establish IP connectivity. 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. 5  Establish the time of day. 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). 6 Establish security. Keys for privacy are exchanged between the cable modem and the CMTS. 7  Transfer operational parameters. 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. 8 Comply with baseline privacy.  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. 9 Enter the operational maintenance state.  As soon as the cable modem has successfully completed above sequence, it enters operational maintenance state. Table B-1 Cable Modem Initialization Steps
