Installation Guide Introduction The ARCXtend HSD Enhanced 5.8 GHz WPE solution is a physical layer wireless bridge device that provides wireless connectivity between a coaxial cable plant and one or more customer sites. The WPE solution operates in the 5,725 MHz to 5,850 MHz frequency band and supports the transparent delivery of one digitally modulated 6 MHz cable downstream EIA standard or HRC cable channels and one3.2 MHz or 6.
Installation Guide The hub connects directly to the coaxial portion of cable plant using a standard power extracting tap and is line powered over coax using 60 or 90 VAC. The CPE is installed at the customer site, connects to a standard cable modem, and is powered over the coax cable using a wall mounted AC adaptor and DC to coax power inserter.
Installation Guide The Hub The Hub is a self-contained weather-protected, strand mountable unit providing a bidirectional wireless connection between a cable plant and a cable modem. The Hub includes an integrated transceiver, patch antenna, embedded cable modem, hub controller and Arcwave’s ARCSmart intelligent management software. Interfaces The following illustration shows the rear of the Hub and identifies the interfaces.
Installation Guide Alignment Brackets Mechanically adjustable horizontal and vertical hub alignment brackets for aligning the hub’s integrated antenna to the desired coverage area. A 7/16” wrench is the only tool required for mounting and aligning the hub. RF W/AC An AC surge protected SCTE compliant female F-type connector for the RF and AC power connection to the cable network.
Installation Guide LED Green/amber weather proof status LED indicating: Amber Solid Amber Blinking Green Blinking Green Solid Power ON Embedded cable modem has Downstream Lock Embedded cable modem has Upstream Lock Embedded cable modem is Operational Ground Lug The ground lug terminal is for bonding the hub chassis to the strand wire. MAC address Each hub model has a unique MAC address as indicated on the label located on the rear of the unit.
Installation Guide The CPE The CPE is a small footprint weatherproof radome that can be easily mounted on a rooftop or side of a building to provide connectivity to the wireless network. It contains an integrated transceiver and a narrow-beam antenna that can be easily aligned to receive the signal from a Network Hub. The CPE is roughly one foot square and supports low cost installation using the same hardware and skills as a small satellite dish.
Installation Guide RF W/DC An SCTE compliant F-type connector provides the RF connection to the cable modem and for powering the CPE. The CPE operates on 18 Vdc nominal which is provided by the Arcwave supplied wall mounted 120 VAC CPE adaptor and DC power inserter, model number AX3655-PS-24. The DC inserter must be located within 300 feet of the CPE to ensure a minimum input voltage of 12 VDC at the RF W/DC port. The CPE can accept an input RF signal between 10 and +30 dBmV from the cable modem.
Installation Guide Deploying the ARCXtend Equipment Personnel installing the equipment must be familiar with basic cable drop, cable modem and ARCXtend WPE solution installation and troubleshooting techniques.
Installation Guide Installation Overview The installation process involves major four steps: • Wireless link planning • Installing the hub • Installing and aligning the CPE(s) • Installing the customer cable modem Wireless link planning Wireless link planning is essential to the success of WPE installation and is highly recommended before attempting to install the equipment.
Installation Guide Installing the hub This section provides instructions on how to install the hub on a cable strand with AC power provided over the coaxial cable. The hub can also be installed on a rooftop, mast or tower using the AX1655-SMA pole mount adaptor kit. It can be powered using power over Ethernet per the wiring diagram provided in the previous section. Aligning the hub Attach the bracket to the messenger strand with the two hanger bolts.
Installation Guide Verify that the hub has power and the embedded cable modem has achieved operational status. Configuring the Link Link activation is accomplished using the ARCSmart HTTP web browser interface or the ARCNet element management system. The parameter names and assignments are the same for both interfaces. Detailed information is available for both tools in their respective user and installation guides located on the Arcwave Support Extranet, http://www.arcwaveinc.com/support.html.
Installation Guide PARAMETER DESCRIPTION Cable Interface Control Choose “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 “Disable” will prevent the ECM from continually scanning for a downstream channel, when none is present.
Installation Guide PARAMETER DESCRIPTION such as digital video or CBR voice. Note: “Cable Interface Control” must be set to “Enable” in order for this element to be set to “Enable”. The default setting is “Enable”. Local Ethernet Interface Control Choose “Enable” to allow local connection to the Hub via the RJ-45 connector. Choose “Disable” to disable the RJ-45 connection and prevent anyone from connecting locally to the Hub.
Installation Guide PARAMETER Upstream Attenuation (Continued) DESCRIPTION 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” . The default setting is “99”. Downstream Air Frequency Choose the downstream wireless carrier frequency. Valid settings for AX1655 model Hubs are: 5813, 5819, 5825, 5831, 5837, and 5843 (in MHz).
Installation Guide PARAMETER Alarm Mask (Continued) DESCRIPTION 0095 (Hex), which corresponds to 10010101 (Binary). The bits that correspond to the alarms we want turned on have been set to 1 and the rest have been set to 0. The defautl setting is all F’s. Alarm Destination Enter up to (5) IP addresses where SNMP traps are to be routed to by the Hub. The default setting is all 0”s.
Installation Guide Installing the CPE Install the mounting hardware (e.g. non-penetrating roof mount, eaves mount) and coaxial cable per the manufacturer’s recommended procedures and in accordance with the National Electric Code and local ordinances. Loosen the (4) mounting bolts and slide the CPE on the mounting pipe. Visually align the CPE in the direction of the Hub and snug the mounting bolts to hold the CPE in place. Install the coaxial cable and ground connections as shown in the illustration below.
Installation Guide Please note the following during installation: • The CPE accommodates a mounting pipe with of 1-1/4” to 2-3/8” in diameter and the CPE and mounting pipe require a minimum of 12 inches clearance on all sides for optimal performance. • The CPE should be located as close to the edge of the building nearest the hub as possible.
Installation Guide Power level is too high Install one or more 10 dB (AX3155-ECF-10) or 20 dB (Ax3155-ECF-20) low pass attenuators between the power inserter and the cable modem. If more than 30 dB of attenuation is required, reduce the hub’s downstream power setting. Power level is too low Verify the CPE alignment. Verify the hub’s downstream power setting.
Installation Guide Cable Modem Installation Connect the cable modem to the TV port of the DC inserter as shown in the prior illustration. Set the upstream signal level Using the cable modem’s diagnostic interface, check that the upstream signal (US) level is within the desired operating range, typically +40 to +50 dBmV with a minimum value of +30 dBmV and a maximum value of +55 dBmV.
Installation Guide Problem Does not detect and lock on to the US channel Solution the following checks: • Verify that the “Select Downstream Power” setting is correct for the downstream modulation and wireless range. • Change “Downstream Air Frequency” to a different channel to rule out interference. • Verify that the range and Fresnel Zone clearance are within specifications.
Installation Guide Problem Solution customer cable modem. If there is no RF output replace the cable modem. If there is an RF output replace the CPE. Cable Modem does not receive an IP address Cable modem does not receive time of day (ToD) Cable modem does not receive the configuration file Cable modem initializes, receives the configuration file, and then reboots Perform normal cable modem installation troubleshooting procedures.
