Name
Transmit TOAC Clock and Sync Inhibit Chan-
nel A. When set to 1, the transmit TOAC clock
and sync are placed in the high-impedance
state.
Transmit J0 Insert Control Channel A. Con-
trol bit, when set to a logic 1, inserts the value in
TJ0DINS[A—D][16:1][7:0] into the outgoing J0
bytes; otherwise, the insert value depends on
TTOAC_J0[A—D] registers. TJ0INS[A] is valid
in STS-48/STM-16 mode.*
Transmit TOAC J0 Byte Control Channel A.
Control bit, when set to logic 0, causes the
default value 00000000 for SONET or
11111111 for SDH to be inserted into the J0
byte in the transmit frame. Setting this bit to
logic 1 causes the TTOAC value to be inserted
into the J0 byte. TTOAC_J0[A] is valid for STS-
48/STM-16 mode.*
Transmit TOAC Odd or Even Parity Monitor
Channel A. When set to 1, even parity is
checked for transmit TOAC channels; other-
wise, odd parity is checked.
Transmit TOAC Byte Control Channel A.
Control bit, when set to logic 0, causes the
default value 00000000 for SONET or
11111111 for SDH to be inserted into those
overhead bytes within the transmit frame that
do not have all specific insert control bits. Set-
ting these bits to logic 1 causes the TTOAC
value to be inserted into those overhead bytes
not having specific insert control bits.
TTOAC_INS[A] is valid for STS-48/STM-16
mode.
Transmit TOAC E2 Byte Control Channel A.
Control bit, when set to logic 0, causes the
default value to be inserted into the E2 byte in
the transmit frame. Setting these bits to logic 1
causes the TTOAC value to be inserted into the
E2 byte. TTOAC_E2[A] is valid for STS-48/
STM-16 mode.
