B IP ADDRESSING The Internet Protocol Suite The Internet protocol suite consists of a well-defined set of communications protocols and several standard application protocols. Transmission Control Protocol/Internet Protocol (TCP/IP) is probably the most widely known and is a combination of two of the protocols (IP and TCP) working together.
64 APPENDIX B: IP ADDRESSING This type of IP Address operates on a subnet mask of ‘255.255.255.0’. See Table 3 for an example about how a network with three computers and a Wireless Cable/DSL Gateway might be configured. Table 3 IP Addressing and Subnet Masking Device IP Address Subnet Mask PC 1 192.168.100.8 255.255.255.0 PC 2 192.168.100.33 255.255.255.0 PC 3 192.168.100.188 255.255.255.0 Wireless Cable/DSL 192.168.100.72 Gateway 255.255.255.
How does a Device Obtain an IP Address and Subnet Mask? Static Addressing Auto-IP Addressing 65 You must enter an IP Address and the subnet mask manually on every device. Using a static IP and subnet mask means the address is permanently fixed. Network devices use automatic IP addressing if they are configured to acquire an address using DHCP but are unable to contact a DHCP server.

D Important Safety Information SAFETY INFORMATION WARNING: Warnings contain directions that you must follow for your personal safety. Follow all directions carefully. You must read the following safety information carefully before you install or remove the unit: WARNING: The Gateway generates and uses radio frequency (rf) energy. In some environments, the use of rf energy is not permitted. The user should seek local advice on whether or not rf energy is permitted within the area of intended use.
70 APPENDIX D: SAFETY INFORMATION ACHTUNG: Stapeln Sie das Geräts nur mit anderen OfficeConnect Gerätes zusammen. ACHTUNG: Aufgrund von internationalen Sicherheitsnormen darf das Gerät nur mit dem mitgelieferten Netzadapter verwendet werden. ACHTUNG: Die Netzsteckdose muß in der Nähe des Geräts und leicht zugänglich sein. Die Stromversorgung des Geräts kann nur durch Herausziehen des Gerätenetzkabels aus der Netzsteckdose unterbrochen werden.
Consignes importantes de sécurité 71 AVERTISSEMENT: Débranchez l'adaptateur électrique avant de retirer cet appareil. AVERTISSEMENT: Ports RJ-45.

GLOSSARY 802.11b 10BASE-T The IEEE standard to which the 3Com OfficeConnect Wireless Cable/DSL Gateway conforms. This standard provides for 1,2,5 and 11Mbps data rates and a set of fundamental signaling methods and other services (see WECA). The IEEE specification for 10 Mbps Ethernet over Category 3, 4 or 5 twisted pair cable. 100BASE-TX The IEEE specification for 100 Mbps Fast Ethernet over Category 5 twisted-pair cable.
78 GLOSSARY networks (100BASE-TX) and can transmit data up to speeds of 100 Mbps. Category 5 cabling is better to use for network cabling than Category 3, because it supports both Ethernet (10 Mbps) and Fast Ethernet (100 Mbps) speeds. Channel Similar to any radio device, the OfficeConnect Wireless Cable/DSL gateway allows you to choose different radio channels in the wireless spectrum. A channel is a particular frequency within the 2.4GHz spectrum within which the Gateway operates.
79 Full Duplex Gateway Half Duplex A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link. A device that acts as a central hub by connecting to each computer's network interface card and managing the data traffic between the local network and the Internet. A system that allows packets to transmitted and received, but not at the same time. Contrast with full duplex.
80 GLOSSARY MAC Address NAT Network Network Interface Card (NIC) Protocol Media Access Control Address. Also called the hardware or physical address. A layer 2 address associated with a particular network device. Most devices that connect to a LAN have a MAC address assigned to them as they are used to identify other devices in a network. MAC addresses are 6 bytes long. Network Address Translation. NAT enables all the computers on your network to share one IP address.
81 connect LANs of a different type; however they connect more LANs than a bridge and are generally more sophisticated. TCP/IP Transmission Control Protocol/Internet Protocol. This is the name for two of the most well-known protocols developed for the interconnection of networks. Originally a UNIX standard, TCP/IP is now supported on almost all platforms, and is the protocol of the Internet.
