BreezeMAX PRO 5000 CPE
Simple Network Management Protocol. A network management protocol that provides
a means to monitor and control network devices, and to manage configurations,
statistics collection, performance, and security. SNMP works by sending messages,
called protocol data units (PDUs), to different parts of a network. SNMP-compliant
devices, called agents, store data about themselves in Management Information Bases
(MIBs) and return this data to the SNMP requesters.
Signal to Noise Ratio. The ratio of the amplitude of a desired analog or digital data
signal to the amplitude of noise in a transmission channel at a specific point in time.
SNR is typically expressed logarithmically in decibels (dB). SNR measures the quality
of a transmission channel or a signal over a network channel. The greater the ratio, the
easier it is to identify and subsequently isolate and eliminate the effects of noise. SNR
also is abbreviated as S/N.
Subscriber Unit
Transmission Control Protocol. Connection-oriented transport layer protocol that
provides reliable full-duplex data transmission. TCP is the part of the TCP/IP suite of
protocols that is responsible for forming data connections between nodes that are
reliable, as opposed to IP, which is connectionless and unreliable.
Transmission Control Protocol/Internet Protocol. A set of protocols developed by the
U.S. Department of Defense to allow communication between dissimilar networks and
systems over long distances. TCP/IP is the de facto standard for data transmission
over networks, including the Internet.
Time Division Duplex is a duplexing technique dividing a radio channel in time to allow
downlink operation during part of the frame period and uplink operation in the
remainder of the frame period.
Trivial File Transfer Protocol. Simplified version of FTP that allows files to be
transferred from one computer to another over a network, usually without the use of
client authentication.
TR-069 CPE WAN Management Protocol (CWMP) was created by the DSL Forum to
standardize management of CPEs over the Wide Area Network (WAN) . The TR-069
protocol specifically defines a common method for CPE devices to communicate with
an Auto Configuration Server (ACS).
Transmit
User Datagram Protocol. Connectionless transport layer protocol in the TCP/IP
protocol stack. UDP is a simple protocol that exchanges datagrams without
acknowledgments or guaranteed delivery, requiring that error processing and
retransmission be handled by other protocols. UDP is defined in RFC 768.
Up Link
Virtual Local Area Network. A group of devices on one or more LANs that are
configured with the same VLAN ID so that they can communicate as if they were
attached to the same wire, when in fact they are located on a number of different LAN
segments. Used also to create separation between different user groups.
