Overview Installation Troubleshooting Contact FAQ Specifications Glossary License Configuration: Basic Gateway TCP/IP Wireless USB P packet packetswitched PacketCable pass-through PAT PCI PCMCIA PDA PDU periodic ranging physical layer piggybacking PING PMD point-to-point POTS port The unit of data that is routed between the sender and destination on the Internet or other packet-switched network. When data such as an e-mail message or other file is sent over the Internet, IP on the sender divides the data into uniquely-numbered packets. The packet header contains the source and destination IP addresses. The individual packets may travel different routes. When all packets arrive at the destination, IP at that end reassembles the packets. The header and the data can vary in length. Packet and datagram are similar in meaning. A scheme to handle transmissions on a connectionless network such as the Internet. An alternative is circuit-switched. A CableLabs-led project to define a common platform to deliver advanced real-time multimedia services over two-way HFC cable plant. Built on DOCSIS 1.1, PacketCable networks use IP technology as the basis for a highly-capable multimedia architecture. A pass-through client on the SBG940 LAN obtains its public IP address from the cable provider DHCP server. Port Address Translation Peripheral Component Interconnect The Personal Computer Memory Card International Association sets international standards for connecting peripherals to portable computers. Laptop computers typically have a PCMCIA slot that can hold one or two PC Cards to provide features such as Ethernet connectivity. personal digital assistant A protocol data unit is a message containing operational instructions used for SNMP. The basic SNMP V2 PDU types are get-request, get-next-request, get-bulk-request, response, set-request, inform-request, and trap. Ranging that is performed on an on-going basis after initial ranging has taken place. Layer 1 in the OSI architecture. It provides services to transmit bits or groups of bits over a transmission link between open systems. It entails the electrical, mechanical, and handshaking procedures. A process that occurs when a cable modem simultaneously transmits data and requests additional bandwidth. A network utility that tests host reachability by sending a small packet to the host and waiting for a reply. If you PING a computer IP address and receive a reply, you know the computer is reachable over the network. It also stands for "Packet InterNet Groper." The physical media-dependent sublayer of the physical layer which transmits bits or groups of bits over particular types of transmission links between open systems. It entails the electrical, mechanical, and handshaking procedures. Physical connection made from one point to another. The "plain old telephone service" offered through the PSTN; basic analog telephone service. POTS uses the lowest 4 kHz of bandwidth on twisted pair wiring. On a computer or other electronic device, a port is a socket or plug used to physically connect it to the network or to other devices. in TCP/IP, a port is a number from 0 to 65536 used logically by a client program to specify a server program. Ports 0 to 1024 are reserved SBG940 User Guide 126
