PRELIMINARY InterReach™ Unison System Description SECTION 2 2.
InterReach™ Unison System Description PRELIMINARY Key System Features • Superior RF performance, particularly in the areas of IP3 and noise figure. • High downlink composite power (+26 dBm), IP3 (+38 dBm) and low uplink noise figure (22 dB for a system with 8 RAUs), enables support of a large number of channels and larger coverage footprint per antenna. • The Main Hub and the Expansion Hub are software configurable. Thus, the frequency band can be field configured.
PRELIMINARY System Hardware 2.
PRELIMINARY InterReach™ Unison System Description 2.3 System OA&M Capabilities The InterReach Unison is microprocessor controlled and contains firmware which enables much of the OA&M functionality. Complete alarming, down to the field replaceable unit (i.e., Main Hub, Expansion Hub, Remote Access Unit) and the cabling infrastructure, is available.
PRELIMINARY OA&M Software 2.3.1 OA&M Software The AdminManager software runs on a Laptop PC which is either directly connected to the DB-9 RS-232 male connector on the Main Hub’s front panel or is remotely communicating through a modem that is connected to the DB-9 connector on the Main Hub’s rear panel. The AdminManager communicates with one Main Hub, and its downstream units, at a time.
PRELIMINARY InterReach™ Unison System Description Figure 2-2 PC/Laptop running AdminManager Use the AdminManager to query units for their status or get current warning and alarm conditions. Local System Monitoring and Reporting The Main Hub checks its own status and polls each of its Expansion Hubs for their status, which includes RAU status. Main Hub The Main Hub receives status of the Expansion Hubs and each of their RAUs, and compares it to previously stored status.
PRELIMINARY Monitoring and Maintaining Unison Remotely 2.3.3 Monitoring and Maintaining Unison Remotely • Using AdminManager Remotely You can use AdminManager to query Unison status via a read-only Configuration & Maintenance panel. You cannot change system parameters or configure system components remotely with AdminManager. (Refer to Figure 2-1 on page 2-4.
InterReach™ Unison System Description 2.3.4 PRELIMINARY Using Alarm Contact Closures The DB-9 female connector on the rear panel of the Main Hub can be connected to a local base station or to a daisy-chained series of Unison, LGCell, and/or MetroReach Focus systems. • When you connect MetroReach Focus or a BTS to Unison, the Unison Main Hub is the output of the alarms (alarm source) and Focus is the input (alarm sense).
PRELIMINARY System Connectivity 2.4 System Connectivity The double star architecture of the Unison system, illustrated in the following figure, provides excellent system scalability and reliability. The system requires only one pair of fiber for 8 antenna points. This makes any system expansion, such as adding an extra antenna for additional coverage, potentially as easy as pulling an extra twisted pair (instead of pulling additional fiber).
PRELIMINARY InterReach™ Unison System Description 2.5 System Operation • Downlink (Base Station to Wireless Devices) The Main Hub receives downlink RF signals from a base station via coaxial cable Main Hub The Main Hub converts the RF signals to IF, then to optical signals and sends them to Expansion Hubs (up to four) via optical fiber cable. Expansion Hub The Expansion Hub converts the optical signals to electrical signals and sends them to RAUs (up to eight) via Cat-5/6 cable.

After the five-second test: • The POWER and UL STATUS LEDs should be green.
PRELIMINARY Installing Expansion Hubs To clean the fiber ports: Use compressed air to blow dust out of each fiber port before you insert the SC/APC connector. Note that compressed air should not leave any residue as this will contaminate the fiber port. To clean the fiber connectors: Be sure that the fiber cable’s SC/APC connectors are clean and free of dust or oils. If the fiber connector front face is not free of dust or oils, follow the manufacturer’s recommendations for cleaning it.
PRELIMINARY Installing Unison Components Splicing Fiber and Pigtail The fiber cable must have SC/APC connectors. If it does not, you can splice a pigtail, which has SC/APC connectors, to the fiber cable. There are two different pigtails: 1 for single-mode fiber (PN 4013SCAPC-3) and 1 for multimode fiber (PN 4012SCAPC-3). To splice the fiber optic cable to the SC/APC pigtail: Option A 1. Secure both the fiber cable and the SC/APC pigtail in a splice tray that is installed immediately adjacent to the Hub.
PRELIMINARY Installing Expansion Hubs To splice the fiber optic cable to the SC/APC pigtail: Option B 1. Secure both the fiber cable and the SC/APC pigtail in a splice tray portion of a fiber distribution panel. 2. Prepare the fiber end by ring-cutting the polyethylene jacket, cutting back the Kevlar strands, and stripping back the fiber cladding. Ensure that sufficient slack is maintained in order to be able to reach the fusion splicer. 3.
PRELIMINARY Installing Unison Components Connecting the ScTP Cables Considerations: • Confirm that the cables have been tested and the results recorded. To connect the ScTP cables: 1. Connect the ScTP cables to any available RJ-45 port on the Expansion Hub. 2. Record which RAU you are connecting to which port. This information is required for the As-Built Document. 3. Tie-off cables or use the optional cable manager to avoid damaging the connectors because of cable strain.
