This requires service providers to increase capacity and coverage, which is typically done by adding new cell sites. However, with city centers becoming more congested and local government zoning regulations becoming more stringent, obtaining permits for new wireless cell sites are becoming increasingly more difficult. Extending service to these hard-to-reach areas often requires overcoming major zoning challenges. The SCS is a cost-effective solution for extending or distributing capacity from base stations to other areas that require coverage. Application Digivance is the only all-digital DAS available today. By using patented technology, the 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 transport allows the signals to be replicated at full dynamic range, independent of the fiber length, which improves data throughput. As advanced, high data-rate broadband services become available, networks with ADC’s SCS technology will be ready. ADC’s digital RF transport technology accommodates enhancements such as free space optical laser links, millimeter wave links and xWDM capabilities. The xWDM option allows multiple transmit and receive paths over a single fiber strand, potentially reducing annual fiber lease costs. Free space optical laser links and millimeter wave solutions can often overcome fiber availability issues where line of sight exists. The 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 challenging service areas. Centralization of base station capacity can also be realized using the SCS. This allows service providers to further benefit by reducing capital expenditures and annual operating costs. Base station radio capacity may be simulcast to multiple remotes by using RF splitting and combining capabilities. The SCS is a cost effective way to solve coverage and capacity problems without assuming the capital expense and time it takes to deploy additional cell sites. System Description The SCS optically transports digitized RF spectrum to difficult coverage areas such as congested city center locations, tunnels, and canyons. A single-band point-to-point RF transport link consists of a Host Unit and corresponding Remote Unit. The SCS Host Unit is typically rack-mounted at the base transceiver station (BTS) site or collocated with other Host Units at a centralized base station radio (BR) suite. The RF spectrum is transported digitally over fiber optic cable connecting the host to a SCS Remote Unit. The SCS Remote Unit is positioned at the area requiring coverage and interfaces with an antenna to distribute the RF signal. The distance between the SCS Host Unit and Remote Unit is typically limited only by protocol response time delay requirements of system modulation standards (iDEN ® , GSM, CDMA, W-CDMA, 1xEV-DO, and HSDPA, etc.), and can be as far as several kilometers. With the product’s 25 dB optical budget, the SCS can be deployed in the most challenging fiber plants.

On the forward path, the Host Unit digitizes the designated RF band and digitally transports it over singlemode fiber to the SCS Remote Unit. On the reverse path, the Host Unit receives the digitized signal 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 can be daisy-chained together to allow monitoring and control of multiple links from a single-user interface. Remote alarm monitoring and control of the SCS can be managed from an off-site location or NOC. Using a standard PC with a standard physical layer protocol, communications can be delivered to the NOC. In addition to sending alarm notifications to the Digivance EMS through software, the SCS Host Unit also features front panel alarm reporting. LEDs on the front panel of the Host Unit will change color depending on the status of the unit. LED displays provide information regarding the following items: • Power • System mode (active/standby) • Indication of faulty unit • RF conditions Furthermore, alarm contact closures provide major and minor alarms. The Host Unit has two alarm contacts that either report system operation is seriously affected (major alarm) or system operation is degraded (minor alarm). The Host Unit operates on DC power. Remote Unit The small-form-factor SCS Remote Unit minimizes visual pollution and offers multiple mounting options that easily blends into the environment. Mounting options for the single- and dual-system remotes include inside pole-mount, pole-wrap, wall-mount, strand-mount and sub-terrain vault- mount capabilities. The Remote Units can be mounted in a vertical or horizontal position often in less than five minutes and are sealed NEMA 6/IP-67 rated enclosures that can be deployed in very harsh environments. Fiber, antenna, and power input/output connectors are all sealed for maximum protection. For installations in areas with significant solar load, ADC offers a solar shield shroud to protect the SCS. On the forward path, the Remote Unit receives the digitized spectrum from the Host Unit and converts the spectrum back into RF to be distributed via an externally mounted antenna system. On the reverse path, the Remote Unit digitizes the designated RF band and digitally transports it over singlemode fiber to the Host Unit. In addition to sending alarm notifications to the EMS software, the SCS Remote Unit also features LED alarm reporting. An LED on the bottom of the Remote Unit will illuminate upon a fault condition.

The EMS consists of a personal computer (PC) using a Windows ® operating system, ADC furnished Java-based software package; an ASCII based RS-232 capable terminal, and RS-232 cables. The EMS can simultaneously monitor a network of SCS links by daisy-chaining the alarm interfaces of up to 24 SCS Host Units. Each of the Host Units are connected through a controller area network bus and the PC can be connected to any of the Host Units. The EMS has the ability to download software, change parameters, and monitor alarms. The EMS provides three levels of alarms: software reporting, LEDs and external contacts. Additionally, off-site functionality is accomplished through a terminal at the NOC using a PC with a standard physical layer protocol for the communications. ADC offers a complete EMS hardware and software turnkey solution to element management, as well as a software solution, where operators utilize their existing element management network. Host Site Capabilities The EMS performs the following functions at the host site: • Provides real-time information regarding faults • Displays various system level values (voltages, RF, power, etc.) • Records and generates history reports with time and date stamps • Adjusts performance related parameters of the Host Unit and Remote Unit • Permits placement of Host Unit and Remote Unit into standby mode • Allows download of new software versions to the Host Unit and Remote Units Off-Site Capabilities The EMS performs the following functions at off- site locations such as the NOC: • Provides real-time information regarding faults • Displays various system level values (voltages, RF, power, etc.) • Adjusts performance-related parameters of the Host Unit and Remote Unit • Permits placement of Host Unit and Remote Unit into standby mode The EMS provides real-time data to the operator at the NOC through an ASCII-based, RS-232- capable terminal. The ASCII terminal at the NOC communicates to the PC at the host site through an RS-232 port. In addition, the operator has the ability to remotely access the EMS over Ethernet, RS-232 to Ethernet connection.
