Figure 9, HOW Broadband Connects Us <br />Buwss Pawky <br />Infrastructure built on the older technologies described above is aging and results in <br />slower, less reliable access to content. Capacity limits of this infrastructure limit service <br />providers' ability to reliably provide high speeds, and in turn, the amount of data <br />consumers can use is also limited. Fiber provides the robust infrastructure that connects <br />telephone, cable and internet infrastructure between communities and around the world. <br />It was originally used by telecommunications for their core infrastructure, to connect their <br />major switching centers, and was only available to their biggest corporate and institutional <br />customers. <br />Today, fiber-optic networks serve homes and businesses throughout the world providing <br />telephone and television as well as internet access services. The next section describes <br />internet access technologies in more detail. <br />Dial -Up Access <br />Though not defined as a broadband technology due to speed and bandwidth limitations, <br />dial-up access still exists. Dial-up internet access uses the public switched telephone <br />network (PSTN) to establish an analog connection from a computer to an internet service <br />provider (ISP). The computer connects via a modem by dialing a telephone number on a <br />conventional telephone line and translating digital data into an analog signal. <br />19 1 P <br />City of San Leandro, CA <br />Fiber Master Plan <br />
