A Side Drop Channel n VT/TU Selection: The eight-bit binary code writ-
ten into this location selects the TU/VT that is to be dropped from the A
side drop bus. Please refer to the operations section for the description for
selecting a VT/TU for a STS-1 in the STS-3 format, and for a TUG-3 in the
STM-1 VC-4 format.
A Side Add Bus Channel n TU/VT Selection: The eight-bit binary code
written into this location selects the TU/VT that is to be added to the A side
add bus. Please refer to the operations section for the description for
selecting a VT/TU for a STS-1 in the STS-3 format, and for a TUG-3 in the
STM-1 VC-4 format.
Reserved
A Side Add Bus Channel n J2 and N2 Message Segments: The follow-
ing locations store the transmit 64-byte J2 message when control bit
ATnJ2TSZ is a 1, and the transmit microprocessor-written 16-byte J2 mes-
sage and 16 byte N2 message when this control bit ATnJ2TSZ is a 0.

A Side Add Bus Channel n V1 Byte: The value written to this location is
transmitted as the V1 byte for the VT/TU selected for the A side add bus
and when control bit ATnTPTV is a 1. Please note: the VT/TU is still sent
with a fixed pointer offset. Bits 7-0 of the register correspond to bits 1-8 of
the V1 byte.
A Side Add Bus Channel n V2 Byte: The value written to this location is
transmitted as the V2 byte for the VT/TU selected for the A side add bus
and when control bit ATnTPTV is a 1. Please note: the VT/TU is still sent
with a fixed pointer offset. Bits 7-0 of the register correspond to bits 1-8 of
the V2 byte.
A Side Add Bus Channel n V4 Byte: The value written to this location is
transmitted as the V4 byte for the VT/TU selected for the A side add bus
and when control bit ATnV4BS is a 1. When control bit ATnV4BS is a 0,
the V4 byte is transmitted with a 0 value. Bits 7-0 of the register corre-
spond to bits 1-8 of the V4 byte.
A side Add Bus Channel n O Bits: The value written to this location is
transmitted as the O bits for the VT/TU selected for the A side add bus and
when control bit TOBWZ is 0. Bits 7 through 4 correspond to bits 3 through
6 in the first justification control byte. Bits 3 through 0 correspond to bits 3
through 6 in the second justification control byte. When control bit TOBWZ
is a 1, the O bits in all channels are transmitted with a value equal to 0.
A side Add Bus Channel n V5 Byte: The value written to this location is
transmitted as the V5 byte for the VT/TU selected for the A side add bus
and when control bit ATnV5BS (bit 0, register X+064H) is 1. When control
bit ATnV5BS is set to 0, a normal V5 byte is transmitted. Bits 7-0 of the
register correspond to bits 1-8 of the V5 byte.
