Bursty Errored Seconds. Seconds with more than one, but less that 320 CRC6
errors.
A signal in which successive "ones" (marks, pulses) are of alternating, positive and
negative polarity, and in which a "zero" (space, no pulse) is of zero amplitude.
Binary digit. The smallest unit of information, representing a choice between a one
or a zero (sometimes called mark or space).
Bits per second. Indicates the speed at which bits are transmitted across a data
connection.
Bipolar Violation. In a bipolar signal, a "one" (mark, pulse) which has the same
polarity as its predecessor.
A small group of bits (usually 8) that is handled as a unit of data.
Bipolar with Eight Zero Substitution. A line coding technique used to accommodate
the ones density requirement of T1 lines.
The International Consultative Committee for Telegraphy and Telephony. (It is now
renamed as the ITU.)
Carrier Detect. The received line signal detector. V.24 circuit 109.
An independent data path.
Challenge Handshake Authentication Protocol.
A letter, figure, number, punctuation, or other symbol.
Customer Identification branch or the CSU menu tree.
A device that receives a specific service, such as database management, from a
server.
Clear Performance Registers branch of the CSU menu tree.
Configuration branch of the CSU menu tree.
A technique used to accommodate the ones density requirements of T1 lines.
The communications port on the CSU.
An identification used by SNMP to grant an SNMP server access rights to a MIB.
A product family and a registered trademark.
The arrangement of a system or network as defined by the characteristics of its
functional units.
Device firmware that establishes specific operating parameters for the device.
Sometimes referred to as straps.
Central Processing Unit failure. A Self-Test Health message indicating a failure in
the device's central processing unit.
Cyclic Redundancy Check. A mathematical method of confirming the integrity of
received digital data.
CRC using six check bits.
Canadian Standards Association.
Channel Service Unit. Protects the T1 line from damage and regenerates the T1
signal.
Control branch of the CSU menu tree.
Clear-to-Send. V.24 circuit 106.
