Bandwidth | The common measure of transmission capacity. For analog transmission, it is
measured in cycles per second; for digital transmission, it is measured in bits
per second.
|
Basic Rate ISDN (BRI) | A 2-wire line-side local switching system port that uses the 2B1Q line code at a 160 kilobit per second rate to transport overhead and up to two B channels and one D channel.
|
Bearer Channel (B Channel) | A 64 kilobits per second channel used for information transfer.
|
Beta Test | The stage at which a new product is tested under actual usage conditions. (Alpha
testing is conducted in-house.)
|
Billing Telephone Number (BTN) | The ten-digit number, including the area code, to which charges for a given
telephone service are billed.
|
Broadband | A data-transmission scheme in which multiple signals share the bandwidth of
a medium such as fiber-optic cable. This allows the transmission of voice, data
and video signals over a single medium; for example, cable television uses broadband
to deliver dozens of channel signals over a single cable.
