During and after failover, the system continues its normal operations with little or no interruption in service. FCC - Federal Communications Commission.The United States'governing body for telecommunications, radio, television, cable, and satellite communications. FDB - See forwarding database (FDB). Federal Communications Commission - See FCC. FHSS - Frequency-hopping spread-spectrum. One of two types of spread-spectrum radio technology used in wireless LAN (WLAN) transmissions. The FHSS technique modulates the data signal with a narrowband carrier signal that "hops" in a predictable sequence from frequency to frequency as a function of time over a wide band of frequencies. Interference is reduced, because a narrowband interferer affects the spread-spectrum signal only if both are transmitting at the same frequency at the same time. The transmission frequencies are determined by a spreading (hopping) code. The receiver must be set to the same hopping code and must listen to the incoming signal at the proper time and frequency to receive the signal. Compare DSSS. forwarding database (FDB) - A database maintained on a DWS-1008 switch for the purpose of making Layer 2 forwarding and filtering decisions. Each entry consists of the media access control (MAC) address of a source or destination device, an identifier for the port on which the source or destination station is located, and an identifier for the virtual LAN (VLAN) to which the device belongs. FDB entries are either permanent (never deleted), static (not aged, but deleted when the switch is restarted or loses power), or dynamic (learned dynamically and removed through aging or when the switch is restarted or loses power).

encryption
- Any procedure used in cryptography to translate data into a form that can be read by only
its intended receiver. An encrypted signal must be decrypted to be read. See also cryptography.
ESS
- Extended service set. A logical connection of multiple basic service sets (BSSs) connected to the
same network. Roaming within an ESS is guaranteed by the D-link Mobility System.
Ethernet II
- The original Ethernet specification produced by Digital, Intel, and Xerox (DIX) that served
as the basis of the IEEE 802.3 standard.
ETSI
- European Telecommunications Standards Institute. A nonprofit organization that establishes
telecommunications and radio standards for Europe.
European Telecommunications Standards Institute
- See ETSI.
extended service set
- See ESS.
Extensible Authentication Protocol
- See EAP.
Extensible Markup Language
- See XML.
failover
- In a redundant system, an operation by which a standby (or secondary) system component
automatically takes over the functions of an active (or primary) system component when the active
component fails or is temporarily shut down or removed for servicing. During and after failover, the
system continues its normal operations with little or no interruption in service.
FCC
- Federal Communications Commission. The United States’ governing body for telecommunications,
radio, television, cable, and satellite communications.
FDB
- See forwarding database (FDB).
Federal Communications Commission

FHSS
- Frequency-hopping spread-spectrum. One of two types of spread-spectrum radio technology
used in wireless LAN (WLAN) transmissions. The FHSS technique modulates the data signal with
a narrowband carrier signal that “hops” in a predictable sequence from frequency to frequency as
a function of time over a wide band of frequencies. Interference is reduced, because a narrowband
interferer affects the spread-spectrum signal only if both are transmitting at the same frequency at the
same time. The transmission frequencies are determined by a spreading (hopping) code. The receiver
must be set to the same hopping code and must listen to the incoming signal at the proper time and
frequency to receive the signal. Compare DSSS.
forwarding database (FDB)
- A database maintained on a DWS-1008 switch for the purpose of making
Layer 2 forwarding and filtering decisions. Each entry consists of the media access control (MAC)
address of a source or destination device, an identifier for the port on which the source or destination
station is located, and an identifier for the virtual LAN (VLAN) to which the device belongs. FDB entries
are either permanent (never deleted), static (not aged, but deleted when the switch is restarted or loses
power), or dynamic (learned dynamically and removed through aging or when the switch is restarted or
loses power).
