Microwave Radiation Warnings

Radio Warning

Under normal operating conditions, Link CX radio equipment complies with the limits for human exposure to radio frequency (RF) fields adopted by the Federal Communications Commission (FCC). All interWAVE Communications, Inc. microwave radio equipment is designed so that under normal working conditions, microwave radiation directly from the radio is negligible when compared with the permissible limit of continuous daily exposure recommended in the United States by ANSI/IEEE C95.1-1991 (R1997), Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.

Microwave signal levels that give rise to hazardous radiation levels can exist within transmitter power amplifiers, associated RF multiplexers, and antenna systems.

Antenna Warning

Designed for point-to-point operation, the Link CX microwave radio system uses directional antennas to transmit and receive microwave signals. These directional antennas are usually circular or rectangular, are generally located outdoors, and are usually mounted with the Link CX on a tower or mast.

The Link CX is classified as a fixed installation product, and per FCC policy guidelines regarding maximum permissible exposure (MPE), antennas used for this interWAVE radio must be installed to provide a separation distance of 2 m (79 in.) or more from all persons during normal operation to satisfy FCC RF exposure limits. As the Link CX is typically mounted on a building or mast high enough to clear ground-level path obstructions, the general population will be further than 2 m (79 in.) from the radio antenna, and the FCC RF exposure limits will be met.

interWAVE Communications, Inc. fully supports the FCC’s adopted MPE limits, and recommends that personnel stay 2 m (79 in.) or more from the front of all directional microwave antennas. Should you have questions about Link CX microwave signal radiation, please contact interWAVE Customer Support.

Never look into the front of an open RF connection or RF antenna as eyes are particularly vulnerable to radiation. Do not disconnect RF coaxial connectors, open microwave units, or break down any microwave screening while the radio equipment is operating.

FCC Regulatory Information

1-2 System Overview

Each Link CX consists of a Link CX radio, with integral antenna (5.3 GHz or 5.8 GHz versions) or an optional external antenna (5.8 GHz versions), as shown in Figure 1-1, along with external power and data cabling. In a typical installation, the Link CX radio and antenna are mounted outdoors, usually on a tower or building. If so equipped, the external antenna connects to the Link CX radio through a factory-supplied coaxial cable.

See Figure 1-1. A radio system, or link, contains two Link CX radios each equipped with either an integral or external antenna, installed at each end of the link, separated by a line of sight transmission path. Frequency band, terrain, actual line-of-sight and environmental conditions influence the range of operation and path performance.

The Link CX carries one full-duplex DS-3 or Ethernet channel, and is powered by a 30-watt external ±21 to ±60 VDC power supply.

1-4 Link CX Basic Structure

1-4.1 Radio Links

Each radio link includes two Link CX terminals. Each terminal consists of a Link CX radio with an integral flat-panel antenna, or a Link CX radio with an external antenna (see Figure 1-1). Generally, the Link CX terminals are mounted outdoors on a tower or building.

1-4.2 Data Stream

The DS-3 or Ethernet data signals enter the Link CX, and are modulated into the RF data stream. The RF radio signal radiates from the local antenna and propagates to the remote antenna. At the remote terminal, the received signal is demodulated and demultiplexed, separating the payload data and the overhead management data.

1-4.3 Link CX Models

The Link CX is manufactured in many configurations:

• Versions with DS-3 or Ethernet carried over 5.3 GHz or 5.8 GHz links.

• Each version available with either an integral 30 x 30 cm (12 x 12 in.) antenna, or with an

N-type connector for a factory-supplied 61 cm (2 ft.) or 122 cm (4 ft.) external antenna, or an N-type connector for a customer-supplied external antenna.

Link CX models are described in Table 1-1.

To ensure longevity in a outdoor environment, interWAVE sells various cables designed for use with the Link CX. interWAVE offers the following weather-resistant cables:

• DS-3 and Ethernet data cables and the power cables are offered in 25 m (82 ft.), 50 m

(164 ft.), and 100 m (328 ft.) lengths.

• A 6 m (19.7 ft.) Ethernet cable is available to route the Ethernet signal between two Link CXs

in the same location, or when you are configuring the Link CX from a Craft PC.

• For models to be used with external antennas, a 2 m (6.6 ft.) N-to-N RF cable is available to

connect the external antenna to the Link CX.

• A 6 m (19.7 ft.) RS-232 4-pin Circular-to-DB9 Craft cable is available to connect a Craft PC

to a Link CX for future CLI applications.

• When the Link CX is to be used with a StreamNet ATM Switch for a mesh backhaul network,

a 6 m (19.7 ft.) dual TNC-to-TNC cable is available to connect each StreamNet ATM Switch to a Link CX.

All of the cables described above include weather-resistant connectors and moisture-excluding gel inside the cable sheaths. For this reason, interWAVE recommends that customers and installers not attempt to shorten or splice the factory-supplied cables.

System Description 9

1-4.7 Integral Antenna

The integral antenna is a 30 cm x 30 cm (12 in. x 12 in.) flat-panel antenna mounted directly on the

5.3 GHz or 5.8 GHz Link CX radio chassis, as shown in Figure 1-4. All RF connections between the integral antenna and the Link CX radio are made internally, eliminating the need for external coaxial cabling. Because the integral antenna is sealed onto the Link CX chassis, the Link CX and integral antenna are mounted as a unit, and share the same environmental protection. An arrow on the connector side of the Link CX chassis indicates the antenna polarization (either vertical or horizontal).

1-4.9 Configuration, Operation, and Monitoring

The Link CX and radio link are configured, operated and monitored through one of five user interfaces. The five interfaces are:

• A built-in web server GUI hosted by the Link CX, which can be accessed by any local or

remote computer equipped with a web browser. This is the interface most operators will use to interact with the Link CX. The web browser can access the Link CX built-in web server through either the ETHERNET 1 or ETHERNET 2 port.

Note that the ETHERNET 1 and ETHERNET 2 ports are functionally equivalent, and that they are both served by an onboard Ethernet controller. The controller automatically switches polarity on the transmit and receive pairs when they are reversed, eliminating the need for crossover cables.

• SNMP traps, which communicate with MIB-II compliant NMSs (Network Management

Systems) and EMSs (Element Management Systems). This interface is used by operators who want real-time notification of radio problems. The Link CX sends SNMP traps to NMSs and EMSs over Ethernet links through either the ETHERNET 1 or ETHERNET 2 port.

• An ASCII command line interface, accessible through the RS-232 CRAFT port, or through

the ETHERNET 1 or ETHERNET 2 port using telnet. This interface is primarily used by operators and interWAVE technical support personnel when performing detailed troubleshooting.

• The RSSI port, providing a DC voltage level proportionate to the received RF signal level, and

allowing installers to use a DC voltmeter to fine-tune antenna alignment. This interface is primarily used during installation, but the current RSSI measurement is also available via the Link CX built-in web server or via SNMP polls.

• Five LEDs that provide visual alarm status. They verify proper operation of the Ethernet

ports, DS-3 ports, and radio link, and indicate proper power input and radio operation. These LEDs are usually used during installation to provide a quick product verification.

1-4.10 SNMP

The Link CX radio supports SNMP network management. SNMP is a protocol that defines the method of communicating with and controlling network devices.

Devices that support the SNMP protocol can be queried for their status and other device information. Some devices allow changing device settings or configurations using SNMP commands. The device settings and other device data are available as variables. They are defined in the standard Management Information Base (MIB) file, provided by the device manufacturer. The SNMP manager uses a database to hold lists of variables that can be accessed for each device on the network. The device data can be displayed in tables, graphs, or saved in a file.

1-4.11 Link CX Network Management Architecture

Link CX software network management is comprised of two main items:

• SNMP based Network Management System (NMS) application in the network management

workstation.

System Description 13

Polling

Traps

• SNMP agent in the Link CX.

The workstation manages all Link CXs assigned unique IP addresses. The workstation also provides a graphical display of the network objects showing the status, performance, and configuration parameters of each Link CX radio.

The SNMP local agent is a standard MIB-II compliant software module that resides in each Link CX. The agent collects information from different Link CX components as defined in the Management Information Base (MIB) structure. The Link CX incorporates both standard and private MIBs.

Different Link CXs are distinguished by their customer-assigned IP addresses. The Web browser communicates with the Link CX using TCP/IP and HTTP protocol.

The NMS data transfer between the manager and the agents is accomplished using either polling or trapping techniques.

The NMS polls each Link CX SNMP agent at specific intervals. These are set according to user requirements during SNMP NMS configuration.

The Link CX agent sends an SNMP trap to the manager whenever a predefined event occurs. Groups of traps can be defined according to their level of severity. The operator can choose to enable or disable any traps or group of traps according to their level of severity (and his or her own security level). Traps can be logged using any standard SNMP manager.

1-4.12 NMS Connectivity

The NMS workstation can access any Link CX using its IP address. The NMS workstation can connect to each Link CX using any of the following methods:

• 10/100 Base-T Ethernet - accessing Link CXs via a LAN through hubs, switches or routers.

• Cascading Ethernet links transport NMS information between colocated Link CXs. This is

done by daisy-chaining the ETHERNET 1 and ETHERNET 2 ports between Link CX radios using straight-pinned or crossover Ethernet cables.

1-4.13 Web-Based GUI Access Security

Access to the Web-based GUI (graphical user interface) is limited by username and password, which is available at different levels of security as follows:

• User - Read only privilege.

• Administrator - Read/partial write privilege. The administrator cannot cause an radio link to

reset by changing critical parameters.

• Supervisor - Full read/write privilege.
