14.8 E13 Basics
E13 multiplexing is a two-step process of merging 16 E1 lines into a single E3 line. First, four of the E1
lines are merged into a single E2 rate and then four E2 rates are merged to form the E3. The first step of
this process is called a E12 function since it is merging E1 lines into E2. The second step of this process
is called a E23 function since it is merging E2 lines into a E3. The term E13 implies that both E12 and
E23 are being performed to map 16 E1 lines into the E3. These two steps are independent and will be
discussed separately.
