TE1
Terminal Equipment Type 1. ISDN-compatible terminals.
Telnet
The TCP/IP standard protocol for remote terminal connection service.
Telnet allows a user at one site to interact with a remote timesharing
system at another site as if the user's terminal were connected directly
to the remote machine.
TCP/IP
Transmission Control Protocol/Internet Protocol. A set of protocols
developed by the Department of Defense to link dissimilar computers
across many kinds of networks.
twisted pair
Two wires twisted around each other to reduce induction (interfer-
ence) from one wire to the other. Several sets of twisted pair wires
may be enclosed in a single cable. Twisted pair is the normal cabling
from a central office to your home or office, or from your PBX to your
office phone. Twisted pair wiring comes in various thicknesses. As a
general rule, the thicker the cable is, the better the quality of the con-
versation and the longer cable can be and still get acceptable conver-
sation quality. However, the thicker it is, the more it costs.
2B+D
The Basic Rate Interface (BRI) in ISDN. A single ISDN circuit divided
into two 64 kbps digital channels for voice or data and one 16 kbps
channel for low speed data (up to 9,600 baud) and signalling. 2B+D
is carried on one or two pairs of wires depending on the interface, the
same wire pairs that today bring a single voice circuit into your home
or office. See ISDN.
23B+D
In ISDN, also known as the Primary Rate Interface. A circuit with a
wide range of frequencies that is divided in twenty-three 64 kbps
