Node B Rack Mount Installation Guide Version 0.0.0 Page 32 of 42 Step 10 Antenna Cabling - Installation Antennas and coaxial cable should be available at the site, and are part of the construction checklist and general assumptions. Two antennae per Node B Radio Shelf are optimum, allowing receiver diversity and transmit diversity (note: if option fitted), therefore two coaxial cables per Node B are needed. Diversity can be via polarization, in which case two feeder runs to the same antenna are needed, feeding oppositely polarised sectors in the same physical enclosure. Cables should be properly marked to indicate what antenna the coaxial cables are to be connected to the Node B serving the sector or area. In the case where only one feeder / antenna is being used, this must be connected to the top connector when viewed from the front of the Node B. The following installation describes the position of the antenna ports and designations. Figure 6-16 : Antenna Connections & Routing

Node B Rack Mount Installation Guide Version 0.0.0 Page 33 of 42 Step 11 Alarm Connections If local alarms are to be utilised two Dtype connectors are been provided on the Node B digital shelf. The specifications for those interface requirements are below:- The maximum input voltage is restricted to 39V for a 500A 8/20 uS pulse, with a minimum working voltage of 18V. All six input circuits are the same. Figure 6-17 : Alarm Outputs & Inputs

Node B Rack Mount Installation Guide Version 0.0.0 Page 34 of 42 Alarm Inputs The 6 external alarm inputs are connected via the 15wayD female type located on the right hand side of the digital shelf. The external alarm inputs are opto-isolated current loops. The voltage and currents shall be supplied by the external source. The pin-out for the alarm inputs are shown in the table below.

Node B Rack Mount Installation Guide Version 0.0.0 Page 35 of 42 Step 12 GPS Installation & Operation The Node B has an external/remote GPS antenna and receiver. The connection for the antenna (N-Type) is located on the Digital Shelf, Figure 6-18. The GPS timing signal is used by the Node B for the TDD frame timing, so that all Node B's in a network are synchronized. The GPS signal is also used by the master oscillator for a frequency reference. The Node B can operate for two hours after a loss of GPS timing but a gradual drift of the frame timing will result in system interference and a loss of Node B selection / reselection capability. A suitable Node B GPS antenna is shipped with every Node B. This antenna should be used with a maximum of 15 metres cable of RG6 type cable plus male N-type connectors at each end. For longer runs, the cable losses will affect signal strength and could impede GPS signal performance. For proper operation of the GPS receiver, the Node B GPS Antenna must have a clear southern view of the sky (northern hemisphere installations). A site survey should be done before Node B installation to verify that the Node B installation location is suitable for GPS reception. A simple survey method is to take a handheld GPS receiver to the site and verify that GPS lock is obtained in the location of the Node B installation. The handheld GPS should be able to obtain a "locked" condition within 2 minutes of power-on, and should be able to see a minimum of 4 satellites at all times. The GPS receiver, integral to the Node B Digital shelf, is automatically enabled when the Node B is powered and there are no adjustments or settings to be made by the user. Note: When the Node B installation is on or near a tower or building wall, the GPS survey should replicate the configuration. Figure 6-18 : GPS Antenna GPS Antenna Field of Vision No Obstructions
