                DCM-100 Ethernet Cable Modem 3

  Thank you for choosing the D-Link DCM-100 digital, two-way DOCSIS 1.0-compliant Ethernet Cable Modem. The DCM-100 provides customers with high-speed access to the Internet through your cable TV (CATV) network connection. It works on any cable system that complies with MCNS DOCSIS specifications and provides a high- bandwidth connection to the Internet. It downloads Web pages almost instantly, transfers files at exceptionally fast speeds, and delivers real-time video and music with unsurpassed quality. The DCM-100 digitizes data and sends it over the cable at up to 10.2 Mbps and can receive transmissions at up to 42.88 Mbps. To give you an idea of just how fast this is, digitized television quality video and audio are transmitted together at about 3 Mbps. The DCM-100 uses a standard RJ-45 port for a 10BASE-T connection to a computer or computer network. When properly configured these connections allow simultaneous data transfers to the Internet via the cable company’s network.
 Designed for versatility and performance, the Ethernet Cable Modem provides the following: Product Features ♦ MCNS/DOCSIS 1.0 compliant ♦ DOCSIS 1.1 upgradeable from DOCSIS 1.0 by software ♦ Building MCNS MIB ♦ Frequency Agility ♦ DES Encryption and Decryption ♦ Automatic Signal Power Recognition/Adjustment ♦ Baseline Privacy Interface ♦ QPSK/16 QAM Upstream Modulation ♦ 64/256 QAM Downstream Modulation DCM-100 Ethernet Cable Modem 4    
       Open the shipping carton and carefully remove all items.

 DCM-100 Ethernet Cable Modem 5 ♦ AC Power Connector - For the included power adapter, if you use a power adapter other than the one included with the product, please make sure it has a DC output of 12V/1A. ♦ Ethernet 10BASE-T Port - The 10BASE-T Ethernet port accepts Category 5 or better UTP cabling with an RJ-45 connector used to connect the DCM-100 to a LAN device (hub, switch, PC, etc.). ♦ Cable In - This jack is used to connect the DCM-100 to the splitter. This connection uses a standard coax cable which is the same cable used by your cable TV company.   In order for you to enjoy the benefits of your Cable Modem, your PC and TV must be properly connected to the cable TV wire. The following diagram illustrates a typical PC/TV installation.
♦ Cable TV Wall Outlet - This is the normal cable TV wall outlet installed by your cable company. If you plan to connect both your TV and your computer to the cable TV wire, the cable TV wall outlet should be connected to a splitter. ♦ Splitter - This unit, usually provided by your cable TV company during installation, splits the signal onto a second wire. The two wires coming out of the splitter can be connected to your TV (or set-top box), and the cable modem. NOTE: 1. If your cable TV company does not provide a splitter or you chose to buy your own, make sure you get one with sufficient frequency range (the range should be printed on the splitter). A range of 5 to 1000 MHz should be adequate. The splitter should provide EMI isol…
