28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
`
1 - Configures the Transmit VT-Mapper block to set the RFI-V bit-fields to the appropriate value, based upon any
defects that the corresponding Receive VT-Mapper block is currently declaring.
BIT 0 - Auto Transmit RDI-V Indicator
This READ/WRITE bit-field is used to select the source of the RDI-V bit-field, within the V5 byte of each outbound
VT1.5/VT2 traffic. In this case, the user has the following two options.
a.
The user can configure the Transmit VT-Mapper block to use an on-chip register as the source of the RDI-V
bit-fields (within the V5 byte). More specifically, the Transmit VT-Mapper block will read out the contents
within BIT6 (Transmit RDI-V value) within the VT Mapper Block - Ingress Direction - DS1/E1 Insertion Control
Register (Address = 0xND43) and it will load this value into the RDI-V bit-field position within each outbound
VT. In this case, the user will have Software Control over the state of the RDI-V bit-fields, within the outbound
VT traffic) or
b.
The Transmit VT-Mapper block will set the RDI-V bit-fields to the appropriate value, based upon any defect
conditions that are currently being declared by the corresponding VT-De-Mapper block.
`
0 - Configures the Transmit VT-Mapper Block to use the on-chip register as the source of the RDI-V bit-field.
`
1 - Configures the Transmit VT-Mapper block to set the RDI-V bit-fields to the appropriate value, based upon any
defects that the corresponding VT-De-Mapper block is currently declaring.
BIT7 - Transmit RFI-V Value:
This READ/WRITE bit-field is used to exercise Software Control over the state of the RFI-V bit-field (within each V5
byte) of the outbound VT data-stream. If the user sets BIT 1 (Auto Transmit RFI-V Indicator), within the VT-Mapper
Block - Ingress Direction - DS1/E1 Insertion Control Register - 2 to 0, then the Transmit VT-Mapper block will read out
the contents within this bit-field, and it will load this value into the RFI-V bit-field within each V5 byte of the outbound VT-
data-stream.
N
OTE
:
This bit-field is ignored if the user sets Bit 1 (Auto Transmit RFI-V Indicator), within the VT Mapper Block -
Ingress Direction - DS1/E1 Insertion Control Register - 1 to 1.
BIT6 - Transmit RDI-V Value:
This READ/WRITE bit-field is used to exercise Software Control over the state of the RDI-V bit-field (within each V5
byte) of the outbound VT data-stream. If the user sets BIT 0 (Auto Transmit RDI-V Indicator), within the VT-Mapper
Block - Ingress Direction - DS1/E1 Insertion Control Register - 2 to 0, then the Transmit VT-Mapper block will read out
the contents within this bit-field, and it will load this value into the RDI-V bit-field within each V5 byte of the outbound
VT-data-stream.
N
OTE
:
This bit-field is ignored if the user sets Bit 0 (Auto Transmit RDI-V Indicator), within the VT Mapper Block -
Ingress Direction - DS1/E1 Insertion Control Register - 1 to 1.
BIT 5 - Transmit AIS-V Indicator
This READ/WRITE bit-field is used to command the Transmit VT-Mappper block to transmit the AIS-V indicator (within
the corresponding VT1.5 or VT2) within the outbound VT-data-stream.
0 - Configures the Transmit VT-Mapper block to NOT transmit the AIS-V indicator within the outbound VT-data-stream.
1 - Configures the Transmit VT-Mapper block to transmit the AIS-V indicator within the outbound VT-data-stream as
shown in
Figure 20
