SDLC (Synchronous Data Link Control)
This level 2 protocol was developed by IBM. While it is not actually a standard
(as being defined by a standards organization) it is commonly used. All data
transmissions are in frames, and the starting flag, address, and control fields are
known as Header information and the FCS and ending flags are known as Trailer
information. See also HDLC.
Server
A device on the network that is dedicated to specific functions.
Signal Framing (Fs)
The framing bit (f) identifies frames 6 and 12 in which signaling states, A and B
are transmitted when traffic on a network is channelized voice service.
SIMM (Single Inline Memory Module)
DRAM that is mounted on a small printed circuit board that can be installed in an
Agilent probe. Also see DRAM.
Simple Network Management Protocol (SNMP)
The Simple Network Management Protocol provides requests and responses
between SNMP managers and SNMP agents. These transactions work with
network management information from Management Information Bases (MIBs)
SLIP (Serial Line Internet Protocol)
A protocol used for serial communications.
Station
A computer or other addressable device on a network, including PCs, terminals,
probes, routers, and mainframes. A station must have an IP address.
STP (Shielded Twisted Pair)
LAN cable that is both twisted, in pairs, and shielded. Pair twisting and shielding
reduces crosstalk to a greater degree than UTP cable, especially at high
transmission rates.
