Transmit Overhead Data Insert Input:
This input pin functions as the Transmit Overhead Data Insert input indi-
cator for the transmit system side interface when the XRT94L31 is con-
figured to operate in STS-1/DS3/E3 mode, however, it functions as the
Transmit STS-1 Overhead Enable output when the device is configured
to operate in the STS-1 mode.
When configured to operate in DS3/E3 mode:
This input pin is used to either enable or disable the Transmit Overhead
Data Input Interface block within the DS3/E3 Frame Generator block.
If the Transmit Overhead Data Input Interface block is enabled, then the
DS3/E3 Frame Generator block will accept overhead data (from the local
terminal equipment) via the TxOH_n input pin; and insert this data into
the overhead bit positions within the outbound DS3 or E3 data stream.
Conversely, if the Transmit Overhead Data Input Interface block is dis-
abled, then the DS3/E3 Frame Generator block it will NOT accept over-
head data from the local terminal equipment.Pulling this input pin "High"
enables the Transmit Overhead Data Input Interface block.
Pulling this input pin "Low" disables the Transmit Overhead Data Input
Interface block.
When configured to operate in STS-1 mode:
These input pins, along with TxOH_n, TxOHEnable_n, TxOHFrame_n
and TxOHClk_n function as the Transmit Overhead (TxOH) Input Port.
These input pins are used to enable or disable the TxOH input port.
If these input pins are pulled "High", then the TxOH port will sample and
latch data via the corresponding TxOH input pins, upon the falling edge
of TxOHClk_n.
Conversely, if these input pins are pulled "Low", then the TxOH port will
NOT sample and latch data via the corresponding TxOH input pins
N
OTE
:
If the TxOHIns_n input pin is pulled "Low", this setting will be
overridden if the user has configured the Transmit SONET/STS-
1 POH Processor or Transmit STS-1 TOH Processor blocks to
accept certain POH or TOH overhead bytes via the external
port.
