Transmit G1 Byte: This byte is used for sending the
microprocessor-controlled states for REI, RDI, and any unassigned bits,
according to the states given in the tables below:
Transmit F2 (User) Channel: This location contains either a
microprocessor-written value or a POH input/output interface value prior to
transmission.
Transmit H4 Byte: This location contains either a microprocessor-written
value or a POH input/output interface value prior to transmission. This byte
is not used for E3 or DS-3 to SDH/SONET applications and is normally
sent with a value equal to 00H.
Transmit F3, K3, and N1 Bytes: These locations contain either a
microprocessor-written value or a POH input/output interface value prior to
transmission.

Transmit O-Bits: These two bits correspond to the two O-bits found in
each of the nine subframes in the DS3 format or the TranSwitch desig-
nated reserved bits in the three subframes in the E3 format. The O-bits are
read once per frame and inserted into each of the subframes.
