Transmit Path Overhead Input Port - Input Pin.
These input pins allow the following actions.
1. Insertion oft the POH data into each of the 12 Transmit SONET POH
Processor blocks (for insertion and transmission via the outbound STS-
12 signal.
2. Insertion of the POH data into each of the 12 Transmit STS-1 POH
Processor blocks (for insertion and transmission via each of the out-
bound STS-1 signals).
3. Insertion of the TOH data into each of the 12 Transmit STS-1 TOH
Processor blocks (for insertion and transmission via each of the out-
bound STS-1 signals).
The function of these input pins, depends upon whether or not the TOH
data is inserted into the 12 Transmit STS-1 TOH Processor blocks.
If the user is only inserting POH data via these input pins:
In this mode, the external circuitry (which is being interfaced to the
Transmit Path Overhead Input Port is suppose to monitor the following
output pins.

The TxPOHFrame_n output pin will toggle "High" upon the falling edge
of TxPOHClk_n approximately one TxPOHClk_n period prior to the
TxPOH port being ready to accept and process the first bit within the J1
byte (e.g., the first POH byte). The TxPOHFrame_n output pin will
remain "High" for eight consecutive TxPOHClk_n periods. The external
circuitry should use this pin to note STS-1 SPE frame boundaries.
The TxPOHEnable_n output pin will toggle "High" upon the falling edge
of TxPOHClk_n approximately one TxPOHClk_n period prior to the
TxPOH port being ready to accept and process the first bit within a given
POH byte.
To externally insert a given POH byte, (1) assert the TxPOHIns_n input
pin by toggling it "High" and (2) place the value of the first bit (within this
particular POH byte) on this input pin upon the very next falling edge of
TxPOHClk_n. This data bit will be sampled upon the very next rising
edge of TxPOHClk_n. The external circuitry should continue to keep the
TxPOHIns_n input pin "High" and advancing the next bits (within the
POH bytes) upon each falling edge of TxPOHClk_n.
If the user is inserting both POH and TOH data via these input pins:
In this mode, the external circuitry (which is being interfaced to the
Transmit Path Overhead Input Port is suppose to monitor the following
output pins.
