Simple network management protocol. A control and reporting scheme widely
used to manage devices from various vendors. SNMP operates on top of the Inter-
net protocol.
Synchronous optical network. A standard format for transporting a wide range of
digital telecommunications services over optical fiber. SONET is characterized by
standard line rates, optical interfaces, and signal formats.
Data set ready. A signal on the DTE interface that indicates if a connection exists
and if the devices are ready to start handshaking control signals so communica-
tions can begin.
Communications in which the timing is achieved by sharing a single clock. Each
end of the transmission synchronizes itself with the use of clocks and information
sent along with the transmitted data.
Transmission rates of 1.544 Mbps are available on T1 communication lines. Also
referred to as digital signal Level 1 (DS-1). See also E1.
Transmission rates of 44.736 Mbps are available on T3 communication lines.
Also referred to as digital signal Level 3 (DS-3).
Time division multiplexing. A technique for transmitting two or more signals at
the same time over a single communication medium. This is accomplished by
allocating channels to the bandwidth for specific increments of time.
The standard TCP/IP remote login protocol specified in RFC-854.
A combination of transmitter and receiver, providing both output and input inter-
faces within a single device.
The signaling of data over telecommunications channels.
A standard for trunk interface between a network access device and a packet
network that defines signaling for data rates greater than 19.2 kbps.
A non intelligent terminal or terminal emulation mode used for asynchronous
communications. Used to configure the MX2800.
Wide area network. A communications network serving geographically separate
areas. A WAN typically extends a LAN outside the building to link to other LANs
over telephone lines.
