Figure 1-8. Bipolar Format
T1 Synchronization
A long string of zeros on a T1 line would cause the line to lose synchronization
due to lack of pulses. Bay Networks offers Bipolar with 8-Zero Substitution
(B8ZS) for T1 synchronization.
B8ZS substitutes a bipolar violation into a string of eight consecutive zeros at the
transmitting end, and removes the bipolar violation at the receiving end. In a
bipolar violation, the first pulse is in the same direction (positive or negative) as
the previous data pulse (F
igure 1-9).
