E
ELP
stands for “Event Logging Printer,” which is the printer, connected to an INM or
NMP, to which alarms are sent.
Encapsulation
is the process whereby one protocol layer receives a message from a higher layer and
attached a header to the message for transmission to the next lower layer or out over
the network.
Ethernet
is a LAN technology defined by IEEE standard 802.3, which supports CSMA/CD
(carrier sense multiple access/collision detection) protocol.
Event
see “Alarm.”
Event log
is a mechanism in the FRX8000/N7000 software that passes alarms on to screens,
printers, and/or files, depending on how alarm reporting is configured in the Node file.
F
Fragment
is an IP datagram that is a piece of a larger datagram, the larger one having been seg-
mented to allow it to pass through a network that did not support the larger datagram.
(See “Fragmentation.”)
Fragmentation
is the breaking up of IP datagrams into smaller segments, to allow the datagrams to
pass through a network that does not support the full size. If IP fragments the data-
grams, they will be reassembled at the final destination; if another protocol fragments
them (for example, to pass through an X.25 network), they will be reassembled at the
other side of that network.
Frame
is a unit of data transmitted between OSI level 2 entities, and containing its own
control information for addressing and error checking.
Frame relay
is transmission of data in a format that combines level 2 and level 3 functionality, but
provides connection information only for level 2.
FTP
stands for the MIL-STD-1780 (Military Standard 1780) File Transfer Protocol, which
allows transfer of ASCII, EBCDIC, and binary files between devices using the pro-
tocol.
