BIT 5 - E2 Byte Insert Method
This READ/WRITE bit-field is used to specify the source of the contents of the E2 byte, within the transmit output STS-
1/STS-3 or STS-3 data stream.
0 - E2 Byte is obtained from TxTOH Serial Input Port.]
1 - E2 Byte is obtained from the contents within the Transmit Transport - E2 Byte Value register (Address Location =
0x0747). This selection provides the user with software control over the value of the outbound E2 byte.
BIT 4 - E1 Byte Insert Method
This READ/WRITE bit-field is used to specify the source of the contents of the E1 byte, within the transmit output STS-

0 - E1 Byte is obtained from TxTOH Serial Input Port.
1 - E1 Byte is obtained from the contents within the Transmit Transport - E1 Byte Value register (Address Location=
0x0743). This selection provides the user with software control over the value of the outbound E1 byte.
BIT 3 - F1 Byte Insert Method
This READ/WRITE bit-field is used to specify the source of the contents of the F1 byte, within the transmit output STS-
1 or STS-3 data stream.
0 - F1 Byte is obtained from TxTOH Serial Input Port.
1 - F1 Byte is obtained from the contents within the Transmit Transport - F1 Byte Value register (Address Location=
0x073F). This selection provides the user with software control over the value of the outbound F1 byte.
BIT 2 - S1 Byte Insert Method
This READ/WRITE bit-field is used to specify the source of the contents of the S1 byte, within the transmit output STS-
1 or STS-3 data stream.
0 - S1 Byte is obtained from TxTOH Serial Input Port.
1 - S1 Byte is obtained from the contents within the Transmit Transport - S1 Byte Value register (Address Location=
