Bit 7 - DS1 Channel 27 Loop-back Request Inter-
rupt Status
This “Reset-upon-Read” bit-field indicates whether
the “DS1 Channel 27 Loop-back Request” interrupt
has occurred or not.
This bit-field will be set to “1” if the “DS1 Channel 27
Loop-back Request Interrupt” has occurred since the
last read of this register.
This bit-field will be set to “0” if the “DS1 Channel 27
Loop-back Request” interrupt has NOT occurred
since the last read of this register.
NOTE: This bit-field is ignored if the XRT72L13 is config-
ured to operate in the “ITU-T G.747 Mode”.
Bit 6 - DS1 Channel 26 Loop-back Request Inter-
rupt Status
This “Reset-upon-Read” bit-field indicates whether
the “DS1 Channel 26 Loop-back Request” interrupt
has occurred or not.
This bit-field will be set to “1” if the “DS1 Channel 26
Loop-back Request Interrupt” has occurred since the
last read of this register.
This bit-field will be set to “0” if the “DS1 Channel 26
Loop-back Request” interrupt has NOT occurred
since the last read of this register.
Bit 5 - DS1 Channel 25 Loop-back Request Inter-
rupt Status
This “Reset-upon-Read” bit-field indicates whether
the “DS1 Channel 25 Loop-back Request” interrupt
has occurred or not.
This bit-field will be set to “1” if the “DS1 Channel 25
Loop-back Request Interrupt” has occurred since the
last read of this register.
This bit-field will be set to “0” if the “DS1 Channel 25
Loop-back Request” interrupt has NOT occurred
since the last read of this register.
Bit 4 - DS1 Channel 24 Loop-back Request Inter-
rupt Status
This “Reset-upon-Read” bit-field indicates whether
the “DS1 Channel 24 Loop-back Request” interrupt
has occurred or not.
This bit-field will be set to “1” if the “DS1 Channel 24
Loop-back Request Interrupt” has occurred since the
last read of this register.
This bit-field will be set to “0” if the “DS1 Channel 24
Loop-back Request” interrupt has NOT occurred
since the last read of this register.
Bit 3 - DS1 Channel 27 Loop-back Request Inter-
rupt Enable
This “Read/Write” bit-field permits the user to enable
or disable the “DS1 Channel 27 Loop-back Request”
Interrupt.
Setting this bit to “0” disables this interrupt. Con-
versely, setting this bit to “1” enables this interrupt.
NOTE: This bit-field is ignored if the XRT72L13 is config-
ured to operate in the “ITU-T G.747 Mode”.
Bit 2 - DS1 Channel 26 Loop-back Request Inter-
rupt Enable
This “Read/Write” bit-field permits the user to enable
or disable the “DS1 Channel 26 Loop-back Request”
Interrupt.
Setting this bit to “0” disables this interrupt. Con-
versely, setting this bit to “1” enables this interrupt.
Bit 1 - DS1 Channel 25 Loop-back Request Inter-
rupt Enable
This “Read/Write” bit-field permits the user to enable
or disable the “DS1 Channel 25 Loop-back Request”
Interrupt.
Setting this bit to “0” disables this interrupt. Con-
versely, setting this bit to “1” enables this interrupt.
