3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
STEP 2 – Induce a “0 to 1 transition” in Bit 0 (Insert Single NDF Event) within the “Transmit SONET
Path – Transmit Path Control” Register; as depicted below.
Transmit SONET Path – Transmit Path Control Register (Address = 0xN9B7)
Once the user induces this “0 to 1 transition” in Bit 0, then the following events will occur.
• The “N” bits, in the H1 byte (within the very next outbound STS-1 frame) will be set to the value “1001”.
• The ten pointer value bits (within the H1 and H2 bytes) will be set to the value that was written into the
“Transmit SONET Path – Transmit Arbitrary H1 Byte Pointer” and “Transmit SONET Path – Transmit Arbitrary
H2 Byte Pointer” registers; during STEP 1.
