3-28 Cisco Integrated Services Router Hardware Installation Guide Chapter 3 Connecting the Router Cisco 860, 880, 890 Series NoteAntenna orientation can increase or decrease signal reception due to polarization. Typically, an SP’s transmitting antenna on the BTS is a vertically polarized omnidirectional antenna, which means the electromagnetic waves are transmitted from it in a vertical plane. Hence, the receiving antenna needs to be vertically oriented too in order to receive the best signal. As the angle of the antenna orientation is changed from vertical to horizontal, only an angular component of the signal is picked up by the antenna. Therefore, if the antenna orientation is horizontal, the antenna picks up the least signal. The signal is received by the antenna as a result of it bouncing off of reflective surfaces. Hence, depending on where the antenna is placed, it may receive different signal strengths. However, the recommended position is vertical. For additional information on all the available cables and antennas available for 3G, go to: http://www.cisco.com/en/US/docs/routers/access/1800/1861/software/feature/guide/mrwlsgsm.html#w p1262730 Connecting a Data BRI Port You can connect the Data BRI port to the ISDN service provider as a backup link to the WAN port in case the primary xDSL (general term referring to various forms of DSL, including global industry standard symmetrical high-speed DSL [G.SHDSL]) WAN service fails. The Data BRI connection is not available on the third-generation (3G) models. The cabling requirements for the ISDN S/T connection are as follows: You must provide two unshielded Category 5 cables. The first cable connects the NT1 box to the splitter, and the second cable connects the splitter to the wall jack. There are RJ-45 connectors at both ends of the default orange ISDN S/T cable. However, an RJ-45–to–RJ-11 ISDN S/T cable is available upon request if the wall jack at the site requires an RJ-11 connector. Contact your router reseller for the appropriate cable. CautionBoth LAN and WAN ports use RJ-45 connectors. Use caution when connecting cables to these connectors. To avoid damage to the router, do not connect telephone-network voltage (TNV) circuits (such as ISDN or DSL circuits) to safety extra-low voltage (SELV) circuits (such as LAN circuits).
