E-10 MX2810 M13 User Manual 61185001L1-1

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.

synchronous

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 informa

tion 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).

TDM

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.

Te lnet

The standard TCP/IP remote login protocol specified in RFC-854.

transceiver

A combination of transmitter and receiver providing both output and input

interfaces within a single device.

transmission

The signaling of data over telecommunications channels.

V. 35

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.

VT 100

A non-intelligent terminal or terminal emulation mode used for asynchronous

communications. Used to configure the MX2810.
