B Channel
The "bearer" channel, in the ISDN scheme. With both Basic Rate and Primary Rate ISDN, this is a full duplex 64Kbps channel for sending and receiving data. See Basic Rate Interface, B Channel, Integrated Services Digital Network, Primary Rate Interface.
BABT
British Approvals Board for Telecommunications
Backbone
That part of a network, which is used as the main path for carrying traffic between network endpoints.
Bandwidth
Bandwidth is a measure of the amount of data that can be transmitted down a telecommunication link. The rate of data flow is expressed in terms of the number of data bits transmitted per second e.g. kbps(thousands of bits per second) or Mbps(millions of bits per second).The broader the bandwidth the larger the amount of data that can be sent. For example; a coaxial cable may have a data rate of 140 Mbps, enough to carry, at any one time, the information for two TV channels or nearly 300 music channels or about 2000 telephone channels. Optical fibres have even greater data rates of 500 Mbps or more. Coaxial cable is considered as broadband, whereas telephone wire (twisted pair) is narrowband.
Baseband
Using the entire bandwidth of a transmission medium, such as copper cable, to carry a single digital data signal.
BGP
Border Gateway Protocol, an Internet protocol that enables groups of routers to share routing information so efficient, loop-free routes can be established. BGP is commonly used within and between Internet Service Providers
Broadband
Sharing the bandwidth of a medium such as copper or fiber optic cable, to carry more than one signal.
