CHAPTER
3.0 Getting Started with OBR3650
3.1 Before You Begin
The OBR3650 provides the base station component of the Vecima VistaMAX system. To set up and configure the base
station, you require the following:
•
One VistaMAX OBR3650 base station with a stand-alone Power over Ethernet (PoE) or WES800 Ethernet Switch
•
One VistaMAX outdoor subscriber station or indoor subscriber station such as the OSR3500C or ISR3510.
•
One of the following components to provide the DHCP and TFTP server:
– Vecima’s Network Management 8000
– A third-party DHCP and TFTP server as per the WiMAX standard. This setup is not covered in this manual.
Setting up the system using NMS8000
Using the NMS8000 as the provisioning tool for all OSR subscriber stations and hosts on the VistaMAX system is the
most common scenario. The platinum, gold, silver, or bronze VistaMAX starter kits available from Vecima Networks
includes an NMS8000.
NOTE
If you wish to connect Internet-accessible hosts to the VistaMAX system, you will need to provide a router with
a public IP address and a valid DNS server. When you are connecting to Internet-accessible host and using the
NMS8000, Vecima recommends connecting one of the NMS8000 Ethernet interfaces on a public routeable IP
address.

3.2 Overview of Configuration
The following steps outline the process for configuring a VistaMAX system. This process assumes that you are using an
NMS8000.
Step 1
Use CAT5 straight-through Ethernet cables to connect the physical components as shown in Using
NMS8000 to Provision VistaMAX System.
Step 2
Use the Web-based interface to configure the IP addresses for the base station and subscriber station(s).
If necessary, configure the IP addresses for the NMS8000.
Step 3
Use the Web-based interface to configure the radio parameters for the base station and subscriber
station(s).
Step 4
If necessary, use the Web-based interface for the NMS8000 to add the subscriber stations on the
NMS8000.
Step 5
Establish the link between the base stations and subscriber stations and verify that the subscriber stations
are online.
The steps that pertain to the base station are described in more detail below. For more information, refer to the NMS8000
& NMS8000/SSP Network Management Server Installation and Operation Guide or related information listed

3.4 Configuring the Network
You will need to configure your network to establish communication between the network elements. Figure 3-2 shows
an example of a properly configured network. The example shows a network configuration using default values. If you
purchased a WiMAX starter kit, these value will already be set.
The VistaMAX Base Station is shipped with a default IP address. However, depending upon your network configuration,
you may want to change the IP address of your Base Station.
Figure 3-2 Network Diagram
As per the WiMAX standard, the subscriber station requires an IP address and TFTP offered to it during network entry.
To fulfill this requirement, both a DHCP and TFTP server must be present. It is possible to use a third-party customersupplied DHCP and TFTP server, but Vecima recommends using the Network Management Server 8000 (NMS8000).
Most Vecima starter kits come with an NMS as part of the solution.
NOTE
Customers who purchased the basic starter kit or who do not have an NMS must use the WiMAX-out-of-the-box
(WOOTB) procedure. For more information about WOOTB, contact the Application Engineering Support at
Vecima Networks.
To configure a network using NMS8000:
Step 1
Open the base station graphical user interface (GUI) and click Configuration > Network Configuration.
The Current Interfaces screen opens displaying the name, IP address, and netmask of the base station’s
primary interface. The default value is 192.168.101.2. To modify this value, click br0 to open the BR0
configuration screen and type the new value in the appropriate field. See “To change the base station IP
address“ below for a detailed description of this Step.
Step 2
Using the NMS GUI, set up and enable DHCP on the NMS, then configure the subscriber stations and host
computers as required.
NOTE
For more information see the NMS8000 & NMS8000/SSP Network Management Server Installation and
Operation Guide.

3.7.8 Setting Service Flow Information
The service flow is part of the Quality of Service (QoS) feature of the base station. Service flows provide the following
functions:
•
Service flows specify a multitude of QoS parameters including: traffic priority, sustained and reserved data rates,
jitter, maximum latency, and specify security profiles.
•
Service flows are setup individually for both uplink and downlink data flows.
•
Service flows classify traffic based on Layer 2, 3 or 4 (Ethernet, IP, TCP/UDP/RTP) header information including
items such as source and destination addresses, port numbers, 802.1Q VLAN IDs, and Ethernet or IP traffic priority
levels.
Before each frame, OBR3650 examines all of the incoming requests and grants a time to transmit for the subscriber
station based on all of the active service flow parameters to guarantee QoS where required. Individual subscriber
stations receive aggregate bandwidth grants from the OBR3650 and must individually manage their own uplink
bandwidth usage.
Setting up a Quality of Service framework:
Step 1
Define a service class and set up its parameters.
Step 2
Define a classifier template and set up its rules.
Step 3
Create service flows and associate them with service classes and classifier templates.
Step 4

APPENDIX
A1 MolexÂŽ Backshell Installation
A defect was detected with the Ethernet terminating end of the MolexÂŽbackshell packaged with the OBR3650. The
terminating modular plug allowed the shielding wire to be improperly grounded, thus making the cable susceptible to
radiated interference. Without proper grounding, the presence of interfering radiation can cause the loss of data packets
between the OBR base station and the WES800.
To fix this problem, Vecima recommends reworking the termination of the Ethernet cable using the JMRJ45S-15
modular plug and properly grounding the cablefeed. The cable termination can be repaired in the field at the tower site.
Once the Ethernet cable termination is repaired, the cable feed will no longer be susceptible to interfering radiation and
the data will be secured.
Figure A-1 JMRJ45S-15 Modular Plug
NOTE
Other than the risk of data loss due to interfering radiation, there is no safety issues concerning the connector
that came with the OBR3650. Where loss of data due to the radiating interference is not a concern, reworking
the terminating end with the JMRJ45S-15 is only necessary as a precaution.
If using a pre-made cable assembly (such as a CAT5CABLE/OD/25, CAT5CABLE/OD/50, CAT5CABLE/OD/75
or CAT5CABLE/OD/100 from Vecima Networks), then the process described in this document is not necessary
CAUTION
Before attaching the backshell, it is highly recommended that the user read through
this entire appendix to become familiar with all of the steps involved to ensure that
none are missed.

A1.3 Attaching the RJ45 Connector
Assembling the JMRM45S-15 Ethernet Terminating End
Step 1
Carefully cut about 1.5 inches (approximately 4 cm) of the jacket. Be careful not to cut the foil that encases
the wires. Vecima recommends that you use an exacta knife to score the length of jacket that you are
removing, then use your needle-nose pliers to carefully split the jacket. If you happen to take off all the foil,
simply remove more of the jacket. When complete, 0.65 inches (or 1.7 cm) of intact foil should be exposed
and the wires should extend another 0.85 inches (or 2.2 cm) beyond that. See Figure Figure A-4.
Figure A-4 Stripped jacket
Step 2
Untwist the wire pairs and separate them. Fold the stranded wire back over the foil. See Figure A-5 below
for a picture of wires prepared for insertion into the connector sleeve.
Figure A-5 Preparing the wires for insertion in connector sleeve
Step 3
Insert each wire through the loading sleeve in the precise order shown in Figure A-6. Ensure that the foil is
closed around the wires and that the loading sleeve is pushed as far back on the cable as possible so that
it is close to the foil. Be sure to insert the wires into the open end of the loading sleeve. Trim the wires so
that the they extend from the foil by 0.4 inches (1 cm). Figure Figure A-7 shows the completed assembly
before crimping.

Step 4
Before installing into the connector bend back the metal strain relief along the cable length. The metal strain
relief should fit just after the jacket and cover the foil.
Check the following before crimping:
1) The wires are in the correct order. See Figure A-6
2) You can see the copper ends of the wires. If the wires are not snug against the connector end, the
connection will be intermittent.
After ensuring that the cable is prepared correctly, crimp the cable using a WT1144 or WT1145 crimping
tool as shown in Figure A-8. The crimped cable is shown in Figure A-9.
NOTE
If no crimping tool is available, use a pair of pliers to crimp the shield to the cable.
Ensure that the shield is securely attached to the cable.

B1 Installing the Antenna - Points to Consider
Improperly installed antennas will add cost, time, and frustration to your operation. Taking some time to plan a proper
installation will have long term benefits.
B1.1 Planning the Installation
Consider the following points when planning an installation:
•
The antenna should support proper grounding and lightning protection.
It is usually far easier to bring the coax into the building where the AC power enters the building; because this is the
easiest and cheapest way to properly bond the cable entrance to the AC ground (coax is easier and cheaper to work
with than #6 AWG copper). Any lightning energy coming in on the coax will be also shared and spread over to the
AC ground system, and there will be no voltage differential between the two ground systems.
•
The antenna should be able to send and receive a strong signal.
The simplest method is to presurvey the proposed location with an antenna and transceiver that are connected via
a temporary string of coaxial cable to a power inserter. The assembly can be mounted to any pole and hand–held
to determine the presence of signal using the integrated beeper.
•
The antenna should support your plan for cableruns.
Cableruns that are too long might decrease the efficiency of signal transmission. Cableruns should be able to
support proper grounding and surge protection. Make sure that you have determined the entire wiring route & needs
before drilling holes in the structure and attaching mounting hardware.
CAUTION
To comply with RF exposure requirements, the integrated antenna or any external antenna which is
connected to an OBR3650 requires a minimum distance of 1.5 meters between it and all persons.
B1.2 Safety Considerations
Before you begin your installation, read all critical safety warnings. See Safety Precautions for more information.
•
Do not put the antenna under a power line. The power line can cause interference, and also exposes the Installation
to unnecessary site hazards.
•
All Installations must meet building and electrical codes. Note that some municipalities have restrictions or
community covenants regarding towers and antenna structures. Check first.
•
Do not install the antenna in high winds or in stormy weather, particularly if lightning is present.
•
Remember to assemble the antenna hardware at a safe location before climbing up to the antenna mount.
•
Depending on your location, you may need two or more people to install the antenna and mount.
B1.3 Evaluating the Mounting Location
You can mount the antenna to a variety of surfaces.
•
The antenna should have a clear line-of-sight to the subscriber station. Do not put the antenna where it will be
blocked by people, animals or vehicles.
Consider how time and the season will affect the line-of-sight. For example, will foilage from growing trees interfere
with the line-of-sight? Will wind or ice add strain to the mounting assembly?

The simple arm supplied with the integrated antenna assembly can be mounted to the side of the house if you can
locate the structural studding.
The simple arm can also be attached to brick or cinder blocks. If mounting to brick, be sure to put the anchors in the
brick only, as anchors will not hold in joint mortar. If mounting to cinder blocks, use toggle bolts that go into the hollow
space in the block.
•
The rooftop will often be another spot to fasten to. This usually is the best location for obstruction clearance. Locating
underlying truss structure can be done with stud finders, looking for nail fasteners through the fascia board, standard
sounding techniques, or from the underside of the roof. To prevent the roof from leaking, you should caulk the holes
with silicone sealant around the holes and at the bottom of the antenna foot where it contacts the surface. Apply the
sealant before you bolt the foot down tight. Be sure to caulk all holes to prevent leaks.
•
An independent radio tower can also be used, but the Installation of these towers is beyond the scope of this
document, usually involving professional structural engineering. Metal towers can provide some of the best lightning
protection since the large metallic structural elements will best carry lightning energy straight to ground.
•
Wooden poles are NOT recommended, because the insulating properties of the wooden pole mean that a large
percentage of a lightning stroke will follow the coax towards the terminal end, even when substantial grounding
conductors are used. Also, wooden poles will sway in the wind putting the antenna beam in and out of alignment in
high wind conditions. By the time the pole is re-guyed to minimize the sway; a properly engineered metal tower could
have been installed.
•
Wind considerations. The integrated antenna has been engineered to operate in 160 Km (100MPH) winds, and
survive in 220 Km (135 MPH) winds, but these forces will generate several hundred Kg. of load to the supporting
mast. At this point, the mounting structure needs to be very secure.
•
The Installation should be accessible year round. Ice might build up in the winter or early spring time.
TIP
When the primary coaxial cable is placed, leave approximately 24” of coaxial cable with a 4” to 6” diameter loop
where the antenna will be installed. This will allow for the required flexibility for adjustment and future servicing.
