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.

Frequency Mapping
The Hub receives a digitally modulated RF signal in the range between 90 and 860 MHZ to and
upconverts it to a selected wireless carrier frequency in the 5,725 to 5,850 MHz 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 downconverts it to an RF channel in the range 425 to 550
MHz (the specific value is wireless carrier frequency minus 5300 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
upconverts it to a pair of fixed frequencies (one high computed as 5,300 MHz plus the RF signal
frequency, one low computed as 5,300 minus the RF signal frequency) in the range 5,250 to 5,350
MHz.
The Hub receives the wireless signal and downconverts 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 -5 to +25 dBmV while providing optimum wireless transmit power. The hub wireless transmitter
power, determined by the Downstream Path Optimization setting, can be set for on of three
modes: High (+19 dBm), Medium (+13 dBm), or Low (+3 dBm).
Note: The “High” power setting is for use with the AX1255-SM-90 and AX1255-VM-90 Network
Hubs. Use of the “High” power setting with the AX1255-SM-25 cancels the FCC certification and
voids the user’s authority to operate the unit in the 5.8 GHz band.
Copyright 2005 Arcwave, Inc.
ARCXTEND USER MANUAL – R1.4, ISSUE 4
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.
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
operation that 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
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 your plant:

ARCXTEND USER MANUAL – R1.4, ISSUE 4
•
•
The AX1255-SM-90 hub includes a 90° beamwidth antenna with a range up to 1 mile at 64
QAM and ¼ mile at 256 QAM;
The AX1255-SM-25 includes a 20° beamwidth antenna with a range of 2 miles at 64 QAM
and 1 mile at 256 QAM.
Wireless Feeder
Figure 2-4: Wireless Feeder
ARCXtend can be deployed as a wireless feeder solution connecting hundreds of customers. An
AX1255-VM vertical mount hub mounts on a utility pole, tower, or building providing the extended
range coverage required for retail districts, office parks, or campuses.
•
The AX1255-VM-90 vertical mount hub includes a 90° beamwidth antenna with a range of 2
mile at 64 QAM and ½ mile at 256 QAM.
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.

DOCSIS 2.0 Compliant ECM
Each Hub includes a hardened DOCSIS 2.0-compliant cable modem (ECM) supporting in-band
communication over standard DOCSIS channels with ARCSmart. For proper operation of
ARCSmart Advanced Network Features the ECM and all cable modems served by the Hub must be
on the same downstream and upstream DOCSIS channels at all times.
The ECM firmware can be upgrading using TFTP and normal cable modem firmware upgrade
procedures.
Watchdog Timer
This embedded cable modem also includes a system watchdog timer with a peripheral bus
interface. It provides a method for resetting the host, upon expiration of the timer value, to heal
system hangs due to software bugs, power spikes, and so on. The watchdog timer period and
prescale values are programmable and are protected by dual keyed-lock state machines. Disabling
of the watchdog timer is protected by both hardware tie-offs and a triple keyed-lock state machine.
Resetting (kicking) of the watchdog timer is provided through a dual keyed-lock state machine.
SNMP-compliant Arcwave Enterprise MIB
The Arcwave Enterprise MIB is compliant with SNMP version 1, 2, and 3 and fully accessible and
manageable using third-party SNMP-based network management tools. It contains all Hub
management, performance, and configuration data. Appendix A of this manual contains a
description and element definitions for the Arcwave Enterprise MIB as implemented in the Hub. The
compilable “arcwave.mib” file is included on each product documentation CD and can also be
downloaded from the Arcwave website.

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:
Copyright 2005 Arcwave, Inc.
12
ARCXTEND USER MANUAL – R1.4, ISSUE 4
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 or 19 dBm
Medium or 13 dBm
Low or 3 dBm
Note: The “High” power setting is for use with the AX1255-SM-90 and AX1255-VM-90 Network
Hubs. Use of the “High” power setting with the AX1255-SM-25 cancels the FCC certification and
voids the operator’s authority to operate the unit in the 5.8 GHz band.
PureBurst Ingress Noise Suppression
PureBurst effectively functions as a door. When there is no wireless upstream signal being received
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.
Copyright 2005 Arcwave, Inc.
13
ARCXTEND USER MANUAL – R1.4, ISSUE 4
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.

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.

Equipment Location
A simple method for choosing the location of the Hub uses a map1 of the area to be covered. 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. Try first to find locations on your plant that fall within the range of the
AX1255-SM-90 and the AX1255-SM-25 and then the AX1255-VM-90.
The AX1255-SM-90 provides maximum coverage area at the expense of limited range, whereas the
AX1255-SM-25 provides maximum range at the expense of limited coverage area. The AX12551
A network map with street and building information is ideal for this activity.

16
ARCXTEND USER MANUAL – R1.4, ISSUE 4
VM-90 provides maximum coverage and maximum range but requires access to a building or tower
for mounting. Locations on building or towers are availably but generally involve a lease agreement
with the owner and the site must be within a thousand feet of the cable plant.
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 Interference
ARCXtend maps the upstream DOCSIS channel to a high frequency and a low frequency pair in the
5.250 to 5.350 GHz band. This mapping is fixed and based solely on the frequency of the upstream
DOCSIS channel. Determine the corresponding wireless channels the upstream frequency used in
your cable plant. Check for interference at both frequencies and note which of these channels are
free of interference, as it will be used for the deployment. If you can’t find free spectrum for the
downstream and upstream signals then you will need to find another 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 monitoring, 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 are that it 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.

Downstream Configuration
The ARCXtend downstream block diagram is illustrated in Figure 3-3. 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.

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-3 in Appendix A provides a list of these channels and their corresponding
center frequencies.
The downstream output of the ARCXtend Hub is the over-the-air frequency in the range of 5729
MHz through 5843 MHz. Any frequency in this range can be chosen from Table 3-4, which
determines the corresponding cable modem receive frequency. Note from the table that the cable
modem downstream receive frequency is always [air frequency – 5300 MHz]. The ARCXtend
standard downstream air frequencies were chosen to ensure that the corresponding cable modem
downstream receive frequencies are centered on standard EIA CATV channels to enable the
fastest possible cable modem downstream scan.
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 air frequency only. 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 4-2. 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

Upstream Block Diagram
The cable modem (CM) is commanded by the downstream signal to transmit at a specific upstream
frequency between 5 MHz and 42 MHz. Note that any upstream frequency may be selected.
Refer to Figure 3-4 from right to left. The ARCXtend Subscriber Transceiver (CPE) up converts the
CM upstream signal to the 5300 MHz band and transmits two copies of the signal: 5300 MHz-[CM
transmit frequency] and 5300 MHz+[CM transmit frequency].
For example, if the CM upstream transmits frequency is 22.5 MHz; the ARCXtend CPE will
simultaneously transmit the signal on two air frequencies: 5277.5 MHz and 5322.5 MHz.
In summary, the CM upstream transmit frequency determines the two upstream air frequencies
transmitted by the ARCXtend CPE. The ARCXtend Hub selects either the high or low air frequency
and passes the user data upstream to the CATV plant at the original CM transmit frequency.

ARCXTEND USER MANUAL – R1.4, ISSUE 4
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 at levels within approximately 25 dB of each other, the combined signal on the upstream
will be unusable.
The solution is to utilize different upstream CM transmit frequencies, and therefore different
upstream air frequencies, in the different Hubs. This means that each CM transmit frequency will
be passed upstream into the CATV plant. Note that this will require the CATV plant and CMTS to
accommodate these separate upstream channels. Recall that DOCSIS supports multiple upstream
channels working with a single downstream. All CMs served by any given Hub must be provisioned
for the same upstream frequency.
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.
21
ARCXTEND USER MANUAL – R1.4, ISSUE 4
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 be prior to installation to confirm with 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 powering power. The internal power supply provides a regulated 24 VDC output
Copyright 2005 Arcwave, Inc.
22
ARCXTEND USER MANUAL – R1.4, ISSUE 4
over an ac input between 45 Vrms and 125 Vrms 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.
Connections are made using standard pin-type connectors with a nominal center-conductor
diameter of 0.067 inches. The minimum length of the center-conductor pin is 1.5 inches and the
maximum length is 1.65 inches. Longer pins can extend past the center-conductor seizure
mechanism and degrade the match. Extremely long pins can result in a short circuit.
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. DC power
should be applied to the CAT5 cable using the “Injector” provided by Arcwave.
Inset RJ-45 pin configuration
RF Signal Power Level and Quality
The Hub requires a downstream path RF power level at the input RF port of between -5 dBmV and
+25 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 12 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 100 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 event log is useful when diagnosing sporadic problems, and can reveal the reason for the ECM
having previously gone offline. Not every line in the log represents an error, even if it is flagged as
an error. Log entries of events affecting the data service are flagged Critical, Alert, or Emergency.
DOCSIS standard events are reported for the ECM and following are the valid ARCSmart 2.0
events:

Select Control Mode
Displays the Hub type, AX1255 or AX1455. This parameter is
used internally by ARCSmart to customize the user interface
based on the Hub type.
Chose the method for managing the Hub.
If Control via HTTP is chosen, then the Hub can be managed
remotely over the cable network or locally via the Hub’s
Ethernet port, using a PC and the HTTP-based user interface.
Cable Interface Control
Copyright 2005 Arcwave, Inc.
If the Control via SNMP is chosen, then the Hub can be
managed remotely over the cable network using SNMP.
Chose “Enable” to turn-on the RF interface of the ECM and
48
ARCXTEND USER MANUAL – R1.4, ISSUE 4
Select Upstream Band
“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 “Off” setting will prevent the ECM from
continually scanning for a downstream channel, when none is
present. The default setting is “On”
Chose which of the two copies of the upstream wireless
carrier being transmitted by the CPE is to be received by the
Hub and passed to the cable network. This parameter is used
to avoid potential interference on the upstream channel.
If High is chosen, then the Hub will receive the upstream
wireless carrier at 5300 MHz plus the frequency of the
upstream channel
If Low is chosen, then the Hub will receive the upstream
wireless carrier at 5300 MHz minus the frequency of the
upstream channel.
Auto Frequency Set
Upstream Frequency
CATV EIA Input Channel
Upstream Attenuation
Copyright 2005 Arcwave, Inc.
For example, if the upstream frequency is 32.0 MHz, the
wireless signal will be transmitted at 5332 MHz (High) and
5268 MHz (Low). As show in Table 5-2, certain combinations
of downstream wireless carrier frequencies and upstream
channels require a specific High or Low setting for optimal
performance. For all other downstream wireless carrier
frequencies, the default setting is High.
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 plugn-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”.
Displays the frequency of the upstream channel that is being
received by the Hub.
Displays the EIA standard channel number of the downstream
channel that is being received by the Hub.
Chose the amount of attenuation (in dB) in the upstream
receive path of the Hub.
49
ARCXTEND USER MANUAL – R1.4, ISSUE 4
If “99” is entered, ARCSmart will automatically set the
attenuation based on the upstream channel transmit power
out of the ECM.
If any other value in the valid range from 0 to 64 is entered,
that the attenuation is set to that value.
This parameter is used to increases or decreases the
upstream 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.
Downstream Air Frequency
Note: “Cable Interface Control” must be set to “Enable” in
order for this element to be set to “99” (Automatic Upstream
Attenuation setting).
Chose the downstream wireless carrier frequency.
Valid settings for AX1255 model Hubs are: 5729, 5735, 5741,
5747, 5759, 5765, 5771, 5777, 5783, 5789, 5795, 5807, 5813,
5819, 5825, 5831, 5837, and 5843 (in MHz).
Downstream Enable
Upstream Enable
Enter Title
Select Downstream Power
The downstream channel frequency out of the CPE is the
Downstream Air Frequency minus 5300 MHz. The default
setting is 5759.
Chose “TRUE” to turn on the downstream wireless transmitter
and “FALSE” to turn it off. The default setting is “TRUE”.
Chose “TRUE” to turn on the upstream wireless receiver and
“FALSE” to turn it off. The default setting is “TRUE”.
Enter a 40 characters alphanumeric string. The default
setting is the MAC address of the ECM. This parameter can
be used to give a unique identifier for the Hub.
Chose the downstream wireless transmitter power setting.
If “High” is selected, the transmit power is set to 19 dBm. (For
use with AX1255-VM-90 and AX1255-SM-90 Hubs only.)
If “Medium” is selected, the transmit power is set to 13 dBm.
Alarm Mask
If “Test” is selected, the transmit power is set to 3 dBm.
Enter the hex value of the events that are to be masked. All

Return of Material Authorization (RMA) Initiation and Tracking
The RMA process is initiated by contacting Arcwave technical support via telephone or e-mail.
Following receipt and review of the RMA request and if the return is authorized, Arcwave will assign
an RMA number. Only after receipt of this number is the customer authorized to ship the product
back to Arcwave. The RMA number is subsequently used to track the status of the return
Onsite Support
Arcwave on-site support service is provided per customer request. The appropriate technical
support engineer will be dispatched to the customer site after agreed upon objectives have been
established between the customer and Arcwave. It is the customer’s duty to make necessary
preparations for the visit, provide access to the relevant sites, and escort Arcwave personnel during
their visit. The customer will also provide security arrangements whenever required. Arcwave will
work with the customer to schedule onsite support in a timely fashion. At the end of the visit,
Arcwave will provide a report summarizing the problem(s) found, corrective action(s) taken, and any
recommendations to prevent the problem(s) from reoccurring in the future.
Copyright 2005 Arcwave, Inc.

ARCXTEND USER MANUAL – R1.4, ISSUE 4
Emergency Onsite Support
If an emergency condition, such as a network outage, arises Arcwave will make every effort to
dispatch the appropriate technical support engineer as soon as reasonably possible and upon
terms agreed to with the customers. This normally means the customer has agreed to pay for
expedited travel and lodging expenses as well as normal emergency onsite support rates.
Software / Firmware Services
Updates
Arcwave will provide periodic software and firmware updates that enhance performance or fix
problems. Software and firmware updates are provided free-of-charge under warranty and with a
service agreement. Arcwave does not typically offer software and firmware updates outside of
warranty or a service agreement so it is strongly recommended that customer’s choose an annual
service agreement.
Upgrades
Arcwave will also offer periodic software and firmware upgrades that provide additional product
functionality. It is often the case that in order to implement the upgrade the customer’s network
must have software and firmware updated to the most current revision to operate properly.

ARCWAVE ENTERPRISE MIB
This guide describes Arcwave Enterprise Management Information Base (Arcwave MIB) Release
2.0. 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.
Arcwave MIB Structure
The Arcwave MIB, named ArcwaveMib has the following structure:

The BRM-3520 Cable
Modem programs the
AR300 Extender Module
with this value based on its
assigned upstream
DOCSIS channel. There is
a one-to-one relationship
between the upstream
wireless frequency and the
upstream DOCSIS
channel.
This element is included
for possible future support
of frequency diversity. It
can also be used when
interference is experienced
one of the two channels.
This element contains the
upstream wireless
frequency (in MHz) that is
being used.
2 = arcwaveUpstreamFreq
- DOCSIS upstream
frequency (in MHz)
1 = arcwaveUpstreamFreq
+ DOCSIS upstream
frequency
The upstream DOCSIS
channel is transmitted by
the ArcWave CPE
simultaneously on two
frequencies:
This element tells the Hub
to tune to one of the two
upstream wireless carrier
pairs.

with this value based on its
downstream channel.
This element sets the
downstream wireless
channel to be used. (in
MHz)
This element sets the gain
on the upstream receiver.
The higher the value the
more attenuation is applied
to the upstream receiver.
Increasing the attenuation
reduces ingress noise onto
the cable plant, but also
decreasing the upstream
wireless range.
This element displays the
downstream channel that
is being used.

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.

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.
