Binary 8-zero substitution. Line-code type, used on T1 and E1 circuits, in which a special code is substituted whenever 8 consecutive zeros are sent through the link. This code is then interpreted at the remote end of the connection. This technique guarantees ones density independent of the data stream. Sometimes called bipolar 8-zero substitution. [..]

Abbreviation for bipolar with eight-zero substitution. A T-carrier line code in which bipolar violations are deliberately inserted if user data contains a string of 8 or more consecutive zeros. Note 1: B8ZS is used to ensure a sufficient number of transitions to maintain system synchronization when the user data stream contains an insufficient numb [..]

A code in which eight consecutive zeros are replaced with the sequence 000+-0-+ if the preceding pulse was + and with the sequence 000-+0+- of the preceding pulse was -, where + represents a positive pulse, - represents a negative pulse, and 0 represents no pulse.

Binary Eight Zero Substitution (B8ZS) B8ZS is a T1 line coding format that makes available all 8 bits of a T1 channel for carrying digitized voice or data. It does this by ensuring the density of 1's on the line is met by the data on the line, or in the case where no data is sent, inserting 1 bits in a predetermined pattern.
