MIB objects unique to a specific company’s devices.
A trap unique to a specific company’s devices.
End of Number.
A discrepancy between a measured or computed value or condition and the true or
specified value or condition.
Errored Seconds. A second with one or more ESF error events (one or more CRC6 error
events or OOFs).
ElectroStatic Discharge. An undesirable discharge of static electricity that can damage
equipment and degrade electrical circuitry.
Extended SuperFrame. The T1 transmission standard that specifies 24 frames as an
extended superframe to be used for frame synchronization and to locate signaling bits.
A type of network that supports high-speed communication among systems. It is a widely
implemented standard for LANs. All hosts are connected to a coaxial cable where they
contend for network access using a Carrier Sense, Multiple Access with Collision
Detection (CSMA/CD) paradigm.
An uncorrected hardware error.
An accidental condition that causes a functional unit to fail to perform its required function.
Federal Communications Commission. The Board of Commissioners that regulates all
electrical communications that originate in the United States.
Facility Data Link. The selected framing bits in the ESF format used in a wide-area link that
are used for control, monitoring, and testing.
Individual DS0 channels that may be sold separately or in groups to provide bandwidth
that is some fraction of the total T1 capability.
One identifiable group of bits that includes a sequence of bits for control, framing, etc.
A high-speed connection-oriented packet switching WAN protocol using variable-length
frames.
A technique that separates bits into identifiable groups.
An extension to MIB II that defines additional objects for control of generic interfaces in
MIB II.
A command providing read-only access to SNMP MIB objects.
A physical connection to earth or other reference point.
High-Level Data Link Control. A communications protocol defined by the International
Standards Organization (ISO).
A computer attached to a network that shares its information and devices with the rest of
the network.
Hertz. A unit of frequency that equals one cycle per second.
Internet Control Management Protocol. Internet protocol that allows for the generation of
error messages, tests packets, and information messages related to IP.
A standard for a LAN protocol suite, implemented as Ethernet.
A shared boundary between functional units.
