Transmit TOH Input Port - Input pin:
This input pin, along with the TxTOHIns input pin, the TxTOHEnable and
TxTOHFrame and TxTOHClk output pins function as the Transmit TOH
Input Port.To externally insert user values of TOH into the outbound
STS-3 data stream via the Transmit TOH Input Port, do the following.
Continuously sample the state of TxTOHFrame and TxTOHEnable
upon the rising edge of TxTOHClk
Whenever TxTOHEnable pulses "High", then the user's external
circuitry should drive the TxTOHIns input pin "High"
Next, output the next TOH bit, onto this input pin, upon the rising edge
of TxTOHClk. The Transmit TOH Input Port will sample the data (on
this input pin) upon the falling edge of TxTOHClk.
N
OTE
:
Data at this input pin will be ignored (e.g., not sampled) unless
the TxTOHEnable output pin is "High" and the TxTOHIns input
pin is pulled "High".

Transmit TOH Input Port - STS-3/STM-1 Frame Indicator:
This output pin, along with TxTOHClk, TxTOHEnable output pins, and
the TxTOH and TxTOHIns input pins function as the Transmit TOH Input
Port.This output pin will pulse "High" (for one period of TxTOHClk), one
TxTOHClk clock period prior to the first TOH bit of a given STS-3 frame,
being expected via the TxTOH input pin.To externally insert user values
of TOH into the outbound STS-3 data stream via the Transmit TOH Input
Port, do the following.
Continuously sample the state of TxTOHEnable and this output pin
upon the rising edge of TxTOHClk.
Whenever the TxTOHEnable output pin pulse "High", then the user's
external circuitry should drive the TxTOHIns input pin "High".
Next, output the next TOH bit, onto the TxTOH input pin, upon the
rising edge of TxTOHClk.
N
OTE
:
The external circuitry (which is being interfaced to the Transmit
TOH Input Port can use this particular output pin to denote the
boundary of STS-3 frames.
