28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
REV. P1.0.6
Bits 7 - 4 - Unused:
Bits 3- 1 - PLM-V RDI Code[2:0]:
These three READ/WRITE bit-field permits the user to specify the value that the VT-Mapper block will transmit, within
the RDI-V bit-fields of the K4 byte (within each outbound VT-frame) whenever (and for the duration that) the
corresponding VT-De-Mapper block detects and declare the PLM-V defect condition.
N
OTE
:
In order to enable this feature, the user must set Bit 0 (Transmit RDI-V upon PLM-V) within this register to "1".
Bit 0 - Transmit RDI-V upon PLM-V
This READ/WRITE bit-field permits the user to configure the VT-Mapper block to automatically transmit the RDI Code
(as configured in Bits 3 through 1 - within this register) towards the remote VT PTE whenever (and for the duration that)
the corresponding VT-De-Mapper block declares the PLM-V defect condition.
`
0 - Configures the VT-Mapper block to NOT automatically transmit the RDI Code (via the K4 byte) whenever (and for
the duration that) the corresponding VT-De-Mapper block declares the PLM-V defect condition.
`
1 - Configures the VT-Mapper block to automatically transmit the RDI Code (via the K4 byte) whenever (and for the
duration that) the corresponding VT-De-Mapper block declares the PLM-V defect condition.
Bits 7 - 5 - TIM-V RDI Code[2:0]:
These three READ/WRITE bit-field permits the user to specify the value that the VT-Mapper block will transmit, within
the RDI-V bit-fields of the K4 byte (within each outbound VT-frame) whenever (and for the duration that) the
corresponding VT-De-Mapper block detects and declare the TIM-V defect condition.
N
OTE
:
In order to enable this feature, the user must set Bit 0 (Transmit RDI-V upon TIM-V) within this register to "1".
Bit 4 - Transmit RDI-V upon TIM-V
This READ/WRITE bit-field permits the user to configure the VT-Mapper block to automatically transmit the RDI Code
(as configured in Bits 3 through 1 - within this register) towards the remote VT PTE whenever (and for the duration that)
the corresponding VT-De-Mapper block declares the TIM-V defect condition.
`
0 - Configures the VT-Mapper block to NOT automatically transmit the RDI Code (via the K4 byte) whenever (and for
the duration that) the corresponding VT-De-Mapper block declares the TIM-V defect condition.
`
1 - Configures the VT-Mapper block to automatically transmit the RDI Code (via the K4 byte) whenever (and for the
duration that) the corresponding VT-De-Mapper block declares the TIM-V defect condition.
