Station
A computer or other addressable device on a network, including PCs, terminals,
probes, routers, and mainframes. A station must have an IP address.
STM-1 (Synchronous Transfer Mode)
Information being transported or switched in regular and fixed patterns with
respect to a frame pattern reference (or some other reference).
STP (Shielded Twisted Pair)
LAN cable that is both twisted, in pairs, and shie lded. Pair twisting and shielding
reduces crosstalk to a greater degree than UTP cable, especially at high
transmission rates.
STS (Synchronous Transport Signal)
The electrical signal rate defined by SONET. See also OC-3.
Subnet Mask
Identifies the subnet field of a network address and is a 32-bit Internet address
written in dotted-decimal notation. A subnet mask is used to divide a network into
sub networks.
SVC (Switched Virtual Circuit)
A virtual circuit which is dynamically created and torn down when no longer
active.
Switch
A network element (NE) that reroutes incoming cells into an outgoing cell stre am
based on each cell’s VPI and VCI.
Synchronous
Signals that are sourced from the same timing reference and hence are identical in
frequency.
TC
Transmission Convergence Sublayer
TE
Terminal Equipment.
