Glossary
ARPA
Advanced Research Projects Agency of the U.S. Department of Defense. ARPA funded research and experimentation with ARPANET,
the predecessor to the Internet.
ATM
Asynchronous Transfer Mode
blank filler plate
An empty panel used to fill vacant subslots on a SIP. For proper operation, a SIP should be fully installed with either functional SPAs
or blank filler plates.
FPD
field-programmable device. General term for any hardware component implemented on router cards that supports separate software
upgrades. SIPs and SPAs must have the correct FPD version to function properly; an FPD incompatibility will disable all interfaces
on the SPA or all SPAs within the SIP.
FPD image package
A software file used to upgrade FPD images. Whenever a Cisco IOS image is released that supports SPAs, a companion SPA FPD
image package is also released for that Cisco IOS software release.
LAN
local-area network. High-speed, low-error data network covering a relatively small geographic area (up to a few thousand meters).
LANs connect workstations, peripherals, terminals, and other devices in a single building or other geographically limited area. LAN
standards specify cabling and signaling at the physical and data link layers of the OSI model. Ethernet, FDDI, and Token Ring are
widely used LAN technologies.
