E2 Framing Structure and E12 Multiplexing
The E2 frame structure is made up of four 212-bit sets (
). 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
positions. When a majority of the three Justification Control Bits from a particular tributary is set to zero,
the Stuffing Bit position will be used for tributary data. When the Justification Control Bits are majority
decoded to be one, the Stuffing Bit will not be used for tributary data.

E3 Framing Structure and E23 Multiplexing
The E3 frame structure and the E23 multiplexing scheme are almost identical to the E2 framing structure
and the E12 multiplexing scheme. The E3 frame structure is made up of four 384-bit sets (
).
The four sets are transmitted one after another (...Set1/Set2/Set3/Set4/Set1...) to make up the complete E3
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 positions. When a majority of the three Justification Control Bits from a particular tributary
is set to zero, the Stuffing Bit position will be used for tributary data. When the Justification Control Bits
are majority decoded to be one, the Stuffing Bit will not be used for tributary data.
