ADC’s Digivance Street-Level CoverageSolution (SCS) helps wireless service providersimprove capacity in dense urban areas whererestrictive zoning requirements prohibitdeployment of necessary network equipment.This digital distributed antenna system (D-DAS)utilizes patented RF transport-over-fibertechnology to distribute wireless servicebetween existing cell sites and SCS remoteantenna units. The low power, small-form-factor remote units offer an unobtrusivedesign and multiple mounting options thateasily blend into the environment. Themaintenance-free design of the remoteantenna units makes the SCS ideal forimproving capacity in hard-to-access areassuch as tunnels, subways, and urban canyons.Digivance®Street-Level Coverage Solution (SCS)Features:• Supports 800 cellular, 800 SMR, 900 SMR,and 1900 PCS• Single-band and dual-band solutions in acompact remote unit• Maintenance-free operation with sealed unit– no fans or filters• Industry’s highest available optical lossbudget – 25 dB• Digital transport is transparent to airmodulation standards; e.g., iDEN®, GSM,CDMA, W-CDMA, IxEV-DO• All-digital transport enables transition tooptional capabilities such as free spaceoptics links and coarse wavelength divisionmultiplexing (CWDM)• Noiseless (no fans) remote is sealed NEMA6/IP-67 rated enclosure with passive cooling• Remote units mount vertically or horizontally– inside pole, pole wrap, wall mount, andstrand mount• Remote alarm monitoring and SNMPsupport• Local alarm networking of multiple systemsfor monitoring and control• Remote unit features integrated WDM tominimize fiber connectionsSPEC SHEET  SPEC SHEET  www.adc.com • +1-952-938-8080 • 1-800-366-3891
OverviewWith the increasing popularity of wireless devices, subscribers expect to have coverage at any time inany place.  This requires service providers to increase capacity, which is typically done by adding new cellsites. However, with city centers becoming more congested and local government zoning regulationsincreasingly more stringent, obtaining permits for new wireless cell sites is becoming nearly impossible.Extending service to these hard-to-reach areas often requires overcoming major challenges. TheDigivance Street-Level Coverage Solution (SCS) is a cost-effective solution for extending or distributingcapacity from base stations to other areas that require coverage.ApplicationDigivance is the only all-digital distributed antenna system (D-DAS) available today. By using patentedtechnology, the Digivance SCS digitizes the entire designated RF band, digitally transports it over fiber,and reconstructs the signal at full bandwidth, regardless of modulation technology. Digital RF transportallows the signals to be replicated at full dynamic range, independent of the fiber length, whichimproves data throughput. As advanced, high data-rate broadband services become available, networkswith Digivance SCS technology will be ready.ADC’s digital RF transport technology is also conducive to enhancements such as free space optical laserlinks instead of physical fiber connections for even faster deployment and CWDM capabilities. TheCWDM option allows multiple transmit and receive paths over a single fiber cable, potentially reducingannual fiber lease costs. Free space optical laser links overcome fiber availability issues, as well as enableservice providers to deploy wireless capacity in specific dense urban areas in days.Digivance SCS offers all the benefits of digital technology in a maintenance-free, compact remote unit.Its versatility and small size allow service providers to quickly deploy networks in areas where zoningrestrictions often hinder installation of base stations. Centralization of base station capacity can also berealized using Digivance SCS. This allows service providers to further benefit by reducing capitalexpenditures and annual operating costs.System DescriptionThe Digivance SCS is an all-digital distributed antenna system (D-DAS) that optically transports RF signalsto difficult coverage areas such as congested city center locations, tunnels, and canyons. One point-to-point RF transport link consists of a host unit and corresponding remote unit.  Base station radiocapacity may be simulcast to multiple remotes by using RF splitting and combining capabilities.The Digivance SCS host unit is typically rack-mounted at the base transceiver station (BTS) site or co-located with other host units at a centralized base station radio (BR) suite. The RF signal is transporteddigitally over fiber optic cable connecting the host to a remote SCS unit. The Digivance SCS remote unitis positioned at the area requiring coverage and interfaces with an antenna to distribute the RF signal.The distance between the Digivance SCS host unit and remote unit is typically limited by time delayrequirements of system modulation standards (iDEN®, GSM, CDMA, etc.), and can be as far as 40 milesor more. With the product’s 25 dB optical budget, the SCS can be deployed in the most challengingfiber plants.Element Management System (EMS)The Digivance EMS provides operational and maintenance capabilities for the SCS product. This EMScan simultaneously monitor a network of Digivance SCS links by daisy-chaining the alarm interfaces ofup to 24 Digivance SCS host units. Each host unit is connected through a controller area network bus,and the PC can be connected to any of the host units. The Digivance EMS has the ability to downloadsoftware, change parameters, and monitor alarms. It also provides three levels of alarms: softwarereporting, LEDs, and external contacts. In addition, off-site functionality is accomplished through a terminal at the NOC utilizing Digivance EMSor Digivance - supported SNMP. Through StarGazer®, ADC’s SNMP manager, enhanced GUI, alarmmanagement and interfaces are provided.8/05 • 1337291 Digivance®Street-Level Coverage SolutionDigivance®Street-Level Coverage Solution (SCS)2www.adc.com • +1-952-938-8080 • 1-800-366-3891
Host UnitThe rack-mountable Digivance SCS host unit is typically located at a BTS or a facility housing a suite ofBTSes. On the forward path, the host unit digitizes the designated RF band and digitally transports itover single mode fiber to the remote SCS unit. On the reverse path, the host unit receives the digitizedsignal and converts it to RF. The host unit also collects alarm information from the remote unit. For system deployments, multiple links can be networked together at the same BTS site. Host units canbe daisy-chained together to allow monitoring and control of multiple links from a single user interface. Remote alarm monitoring and control of the Digivance SCS system can also be managed from an off-site location or NOC. Using a PC with a standard physical layer protocol, communications can bedelivered to the NOC.  In addition to sending alarm notifications to the Digivance EMS throughsoftware, the Digivance SCS host unit also features front panel alarm reporting. LEDs on the front panelof the host unit will change color depending on the status of the unit. LED displays provide informationregarding the following items:• Power • System mode (active/standby)• Indication of faulty unit• RF conditionsFurthermore, alarm contact closures provide major and minor alarms. The host unit has two alarmcontacts that either report system operation is seriously affected (major alarm) or system operation isdegraded (minor alarm). The host unit operates on DC power.Remote UnitThe low power, small-form-factor Digivance SCS remote unit offers an unobtrusive design and multiplemounting options that easily blend into the environment.  Mounting options for the single-band anddual-band remotes include inside pole mount, pole wrap, wall mount, and strand mount. The units,which can be mounted in a vertical or horizontal position in less than five minutes, are sealed NEMA6/IP-67 rated enclosures that can be deployed in the harshest environments. Fiber, antenna, and powerinput/output connectors are all sealed for maximum protection.On the forward path, the remote unit receives the digitized signals from the host unit and converts thesignal back into RF to be distributed via an externally mounted antenna. On the reverse path, theremote unit digitizes the designated RF band and digitally transports it over single mode fiber to thehost unit. In addition to sending alarm notifications to the Digivance EMS software, the Digivance SCS remote unitalso features LED alarm reporting. An LED on the bottom of the remote unit will illuminate upon a faultcondition. The LED will display information about the following:  • System mode (active/standby)• Indication of faulty unit• RF conditions• Power amplifier fault• Antenna fault system (VSWR)8/05 • 1337291 Digivance®Street-Level Coverage SolutionDigivance®Street-Level Coverage Solution (SCS)3www.adc.com • +1-952-938-8080 • 1-800-366-3891
