The amount of time required to transmit a logical one or a logical zero. [T1.106-1988]

A character position in a word in a binary notation.

1. In a bit stream, the number of bits occurring per unit time, usually expressed in bits per second.
Note: For n-ary operation, the bit rate is equal to log2n times the rate (in bauds), where n is the number of significant conditions in the signal.
2. The rate of transmission of information in binary (two state) form in bits… (Read More →)

In digital carrier systems, the practice or technique of preempting, at regular intervals and for the purpose of transmitting signaling information, one digit time slot that (a) is associated with the given user channel for which signaling is required, and (b) is used primarily for transporting encoded speech via that channel.
Note 1: Bit robbing is an option in networks… (Read More →)

In digital transmission, the loss of a bit or bits, caused by variations in the respective clock rates of the transmitting and receiving devices.
Note: One cause of bit slippage is overflow of a receive buffer that occurs when the transmitter's clock rate exceeds that of the receiver. This causes one or more bits to be dropped for lack of… (Read More →)

A sequence of bits.
Note: In a bit stream, individual bit strings may be separated by data delimiters. Synonym binary string.

The insertion of noninformation bits into data.
Note 1: Stuffed bits should not be confused with overhead bits.
Note 2: In data transmission, bit stuffing is used for various purposes, such as for synchronizing bit streams that do not necessarily have the same or rationally related bit rates, or to fill buffers or frames. The location of the stuffing bits… (Read More →)

See nominal bit stuffing rate.

Synchronization in which the decision instant is brought into alignment with the received bit, i.e., the basic signaling element.

Operation in which data circuit terminating equipment (DCE), data terminal equipment (DTE), and transmitting circuits are all operated in bit synchronism with a clock.
Note 1: In bit synchronous operation, clock timing is usually delivered at twice the modulation rate, and one bit is transmitted or received during each clock cycle.
Note 2: Bit synchronous operation is sometimes erroneously referred… (Read More →)
