14.2 M13 Basics
M13 multiplexing is a two-step process of merging 28 T1 lines into a single T3 line. First, four of the T1
lines are merged into a single T2 rate and then seven T2 rates are merged to form the T3. The first step of
this process is called a M12 function since it is merging T1 lines into T2. The second step of this process
is called a M23 function since it is merging T2 lines into a T3. The term M13 implies that both M12 and
M23 are being performed to map 28 T1 lines into the T3. These two steps are independent and will be
discussed separately.
