Acronym for Data Terminal Equipment. It is the end-user terminal or computer that plugs into the
termination point (DCE) of a communications circuit.
gateway
Is a device which enables information to be exchanged between two dissimilar systems or
networks.
HDLC
Acronym for High Level Data Link Control. It is a generic link-level communications protocol
developed by ISO, that manages synchronous code-transparent serial information transfer over a
link connection. See also SDLC.
host computer
The primary or controlling computer in a multiple computer operation.
in-band signaling
is signaling over the same channel used for data.
IP
Acronym for Internet Protocol. It provides for transmitting blocks of data between hosts identified
by fixed-length addresses.
ISDN
Acronym for Integrated Services Digital Network. It is a network architecture that enables end-to-
end digital connections. It supports diverse services through integrated access arrangements
and defines a limited set of standard, multipurpose interfaces for equipment vendors, network
providers, and customers.
LAN
Acronym for Local Area Network. A privately owned network that offers high-speed
communications channels connecting information processing equipment in a limited geographic
area.
MIB
Acronym for Management Information Base. It is a database of network management information
used by SNMP.
multi-point
Is a configuration or topology designed to transmit data between a central site and a number of
remote terminals on the same circuit. Individual terminals are not able to send data to each other.
out-of-band signaling
Is signaling that is separated from the channel carrying information (voice, data, video, etc.) by a
filter.
packet
Is a bundle of data that contains both control information and the data itself. The control
information is used for routing the packet through a network to its final destination.
packet-switching network
Is a telecommunications network based on packet-switching technology, wherein a transmission
channel is occupied only for the duration of the transmission of the packet.
parameter
Is a numerical code that controls an aspect of terminal and/or network operation. Parameters
control page size, data transmission speed, and timing options.
ping
Is an internet protocol standard that provides loop-back on demand for any device in an IP
network. One device "pings" another by sending a loop-back request to the device's IP address.
point-to-point
Is a type of communications link that connects a single device to another single device, such as a
Base unit to a CPE unit.
remote configuration
A feature that allows the CPE unit to be configured from the Base unit or VT-100 compatible
terminal.
router
Is a device that supports LAN-to-LAN communications. IT reads logical addressing information
and directs data across a network to its destination. See also bridge.
