Netopia Router PN Series - Manual (Page 287)

GL-17
Statistical Multiplexing: Interleaving the data input of two or more
devices on a single channel or access line for transmission through
a frame relay network. Interleaving of data is accomplished using
the DLCI.
S/T interface: The inter face on local ISDN equipment where the
connection to an NT1 or a properly terminated ISDN line is made.
The Netopia ISDN Router models 440-S/T and 430-S/T have S/T
inter faces. See also
NT1, U interface.
subnet: A network address created by using a subnet mask to
specify that a number of bits in an internet address will be used as
a subnet number rather than a host address.
subnet mask: A 32-bit number to specify which part of an internet
address is the network number, and which part is the host address.
When written in binary notation, each bit written as 1 corresponds
to 1 bit of network address information. One subnet mask applies
to all IP devices on an individual IP network.
SDLC (Synchronous Data Link Control): A link-level
communications protocol used in an International Business
Machines (IBM) Systems Network Architecture (SNA) network that
manages synchronous, code-transparent, serial information transfer
over a link connection. SDLC is a subset of the more generic HDLC
(High-Level Data Link Control) protocol developed by the
International Organization for Standardization (ISO).
T1: Transmission rate of 1.544 Mbps on T1 communications lines.
A T1 facility carries a 1.544 Mbps digital signal. Also referred to as
DS-1 (Digital Signal Level 1). See also
E1 and channel.
TCP/IP (Transmission Control Protocol/Internet Protocol): An
open network standard that defines how devices from different
manufacturers communicate with each other over one or more
interconnected networks. TCP/IP protocols are the foundation of the
Internet, a worldwide network of networks connecting businesses,
governments, researchers, and educators.
telephone wall cable: 2-pair, 4-pair, or 8-pair, 22- or 24-gauge solid
copper wire cable. Telephone wall cable is sometimes called
telephone station cable or twisted-pair cable.
