Page 8: Overview
1.2.1 FCC Compliance The Link CX-24 is FCC certified for use in the 24 GHz unlicensed band in the United States. 24GHz (24.05-24.250 GHz) When deployed in an area regulated by the FCC, Link CX-24 radios operate under the FCC Part 15.249 band regulations for intentional radiators in a point-to-point configuration. -
Page 9: Applications
Competitive Local Exchange Carriers (CLECs). System Overview Each Link CX-24 consists of a Link CX-24 radio, with integral antenna as shown in Figure 1.2, along with external power and data cabling. In a typical installation, the Link CX-24 radio with integral antenna is mounted outdoors, usually on a tower or building. -
Page 10: Figure 1.2 - Typical Radio Link Configurations
Figure 1.2 – Typical Radio Link Configurations Because the Link CX-24 offers both high and low channels in a single band, and can be installed with horizontal or vertical polarization, up to four Link CX-24 radios can be mounted at each hub, or node, to form part of a star or mesh network. -
Page 11: Features
1.7.2 Data Stream The DS-3 or Ethernet data signals enter the Link CX-24 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 de-multiplexed, separating the payload data and the overhead management data. -
Page 12: Figure 1.4 - Link Cx-24 Interface Connectors And Indicators
To ensure proper mounting and antenna alignment, YDI sells a mounting bracket designed for use with the Link CX-24. The single bracket mounts one Link CX-24. The bracket is designed to provide rugged mounting for the Link CX-24, while allowing fine adjustment for antenna alignment. -

100 m (328 ft.) lengths. • A 6 m (19.7 ft.) Ethernet cable is available to route the Ethernet signal between two Link CX-24 in the same location, or when you are configuring the Link CX-24 from a Craft PC. - Page 15 The five interfaces are: • A built-in web server GUI hosted by the Link CX-24, 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-24. The web browser can access the Link CX-24 built-in web server through either the ETHERNET 1 or ETHERNET 2 port.
- Page 16 Refer to Appendix C for Link CX-24 GUI operating instructions. Configuration Management The NMS software can be used to configure the parameters of the Link CX-24 radio, although this is normally done using a web browser GUI. This includes the setup of templates with predetermined default values, relating to both the parameters of common element types and the validation of parameter values.
- Page 17 Note that the ‘local’ system is the Link CX-24 you are logged into, and the ‘remote’ Link CX-24 is the one at the far end of the radio link. Thus, when you are logged into the far end Link CX-24 on a radio link that terminates at your current physical location, the far end Link CX-24 is ‘local’...

Page 18: Typical Applications
The simplicity of the Link CX-24 installation makes it easy for the user to implement Link CX-24 in a variety of applications. It also means that the user can conveniently move a previously installed Link CX- 24 to a new location to meet the requirements of a changing system. -
Page 19: Installation
Generally, the common points to consider when planning a Link CX-24 network are: Line of Sight: Unlike some frequency bands, the Link CX-24 radios must be within line of sight of each other. That is, the far-end antenna must be visible from the near-end antenna. If there are trees, buildings, mountains, or other obstructions between the two antennas, the Link CX-24s on each end of the radio link will be unable to communicate with each other. -
Page 20: Site Planning
Link CX-24. Mounting Point: The Link CX-24 is usually mounted on a vertical mast or pole mounted on a building or a tower. The Link CX-24 mounting bracket can accommodate a 4.5 to 7.6cm (1.75” to 3” OD) diameter mast or pole. -
Page 21: Planning Element And Network Management Ethernet Links
EMS and/or NMS Ethernet links. The cable run from the Ethernet switch or router to the Link CX-24 must be 100 m (328 ft.) or less, and can be straight-through or crossover, because the Link CX-24 Ethernet ports automatically detect the transmit and receive pairs and switch them if necessary. -

Section 1.7.6. Power Planning YDI sells 25 m (82 ft.), 50 m (14 ft.), and 100 m (328 ft.) power cables with the correct connectors for Link CX-24 power, as described in Section 1.7.6. -
Page 23: Radio Link Planning
Radio Link Planning As described in Section 1.7, each radio link requires a Link CX-24 at each end of the link. Before you start installing the Link CX-24s, make a copy of Table 2.2 and fill in the information for both ends of the radio link: Table 2.2 –... -

Link CX-24 installation instructions have been written for such personnel. Since Link CX-24 is easy to install, a previously installed Link CX-24 can be conveniently moved to a new location. Re-deployment allows the user to meet the requirements of a changing system with minimal effort and expense. - Page 26 Link CX-24 parts. YDI suggests that the user retain at least one (1) of each packing carton with all its packing materials. In the event that it is necessary to return a unit, the user will have the required packing material for safe shipment.
