14.3 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.

E2 Framing Structure and E12 Multiplexing
The E2 frame structure is made up of four 212-bit sets (Figure 14.3A). The four sets are transmitted one
after another (...Set1/Set2/Set3/Set4/Set1...) to make up the complete E2 frame structure. The Frame
Alignment Signal (FAS) is placed in the first 10 bits of Set 1 and is followed by the Remote Alarm
Indication (RAI) bit and a National Bit (Sn). The remainder of Set 1 is filled with bits from the four
tributaries. The four tributaries are bit interleaved starting with a bit from Tributary 1 immediately after
the Sn bit. The first four bits of Sets 2, 3, and 4 are the Justification Control Bits. Bits 5 to 8 of Set 4 are
the Stuffing Bits. The Justification Control bits control when data will be stuffed into the Stuffing Bit
