ATM Asynchronous Transfer Mode Data transmission technology utilizing virtual circuits to transmit text, voice, image, and video data.
CRC Cyclic Redundancy Check Used as a check to detect the alteration of data during data transmission or storage.
DHCP Dynamic Host Configuration Protocol Provides automatic allocation and management of IP addresses to LAN devices.
DMZ DeMilitarized Zone Zone in front of the modems firewall opening the LAN device to full view of the Internet. A device in the DMZ WILL NOT be protected by the firewall of the modem.
DNS Domain Name Server Provides IP to URL translation to find a specific site on the Internet. When a domain as in www.CenturyLink.com is entered into the address bar of your browser, DNS translates the domain to an IP address to find the site on the Internet.
FTP File Transfer Protocol Protocol used to transmit data from one computer to another over the Internet.
GRE Generic Routing Encapsulation Tunneling protocol used to create point to point tunnels over an IP network.
IM Instant Messaging
Real time communication with two or more people using text over an IP network.
IPCP Internet Protocol Control Protocol Network control protocol used to establish and configure a point-to-point link over an IP network.
IP Internet Protocol Protocol used for transferring data over a wide network. IP is the primary protocol used for the Internet.
ISP Internet Service Provider Provides access to the Internet.
LAN Local Area Network Network of computers and devices covering a small area as a home or office.
LCP Link Control Protocol Used to establishing a PPP connection, LCP determines the standards to ensure data transmission.
LLC Logical Link Control Provides flow and error control across all interfaces
MAC Media Access Control Provides addressing and channel access control of devices on the LAN.
NAT Network Address Translator Masks devices on the LAN behind the modem hiding the devices from the Internet.
PPP Point to Point Protocol Established a direct authenticated connection between two network devices. PPP is used to establish a connection between your modem and the CenturyLink network.
PPPoA Point to Point Protocol over ATM Establishes a direct authenticated connection using ATM as the transfer method.
PPPoE Point to Point Protocol over Ethernet Establishes a direct authenticated connection using Ethernet as the transfer method.
PSK Pre-Shared Key A shared secret between two devices to establish a secure wireless connection.
QoS Quality of Service Provides the ability to prioritize different traffic types over another. An example is prioritizing voice traffic over internet browsing traffic.
UPnP Universal Plug and Play Protocol allowing devices to connect to each other seamlessly providing a true plug-n-play experience.
RAM Random Access Memory Randomly accessed modem memory providing resources to run applications stored on the modem. Resources include all modem features and the GUI you are viewing.
RFC Request For Comment Provides a means for developing standards and specifications for protocol development.
RIP Router Information Protocol Identifies the shortest path between two network points with the least number of hops.
RS Reed-Solomon Error correcting technique used to correct errors in data bursts.
SNR Signal to Noise Ratio Compares the desired transmission signal to background noise on a transmission line. The higher the ratio, the better the signal transmission is.
SSID Service Set Identifier Is the name of your wireless network. When you search for a wireless network from a wireless client the network name that appears is the SSID. CenturyLink uses "myCenturyLinkxxxx" and "CenturyLinkxxxx" as default SSID's. The "xxxx" in the default SSID represents the last four digits of your routers serial number making network identification easier.
TCP Transmission Control Protocol Manages a data stream across the Internet ensuring a reliable delivery.
TKIP Temporal Key Integrity Protocol Security protocol used for wireless networks in the framework of WPA.
UDP User Datagram Protocol Allows network devices to send short datagrams to each other without the reliability of TCP.
URL Uniform Resource Locator Standard way of defining where a resource is available on the Internet. If you are looking for CenturyLink on the Internet, the URL www.CenturyLink.com would be used to connect to CenturyLink.
USB Universal Serial Bus Shared bus standard for connecting devices to a host computer. All devices connected the the USB bus share the available bandwidth. USB 1.0/1.1 has a maximum bus rate of 12Mbps where USB 2.0 has a maximum bus rate of 480Mbps.
VCI Virtual Channel Identifier Unique identifier in the ATM world identifying the virtual channel a data stream should take. VCI works in conjunction with the VPI to identify the destination point of the data stream.
VIP Virtual IP Interface Allows for the creation of a private and public subnet with a block of static IP addresses. Using VIP enables you to provide static IP addresses to devices that require a static IP address while providing DHCP addresses to devices that do not require a static IP address.
VLAN Virtual Local Area Network A group of devices that are geographically separated but appear to be in the same place on one LAN.
VPI Virtual Path Identifier Unique identifier in the ATM world identifying the virtual path a data stream should take. VPI works in conjunction with the VCI to identify the destination point of the data stream.
WAN Wide Area Network Network covering a wide area providing connectivity for many LANs. The Internet is considered a big WAN.
WEP Wired Equivalent Privacy Wireless network security protocol providing wireless security with an AP. WEP has been replaced with WPA2 as the preferred wireless security protocol for wireless networks.
WMM Wireless Multimedia Provides traffic QoS on the wireless link of a LAN. WMM allows for the prioritization of traffic by traffic type on the wireless AP.
WPA / WPA2 Wi-Fi Protected Access Wireless network security protocol providing wireless security with an AP. WPA2 is the preferred wireless security type over WEP. WPA2 allows you to create a security phrase instead of having to develop a hexadecimal key with WEP.
