The H1H2EN bit enables the insertion of the H1 and H2 bytes in the transport overhead.
When H1H2EN is a logic one, the values in the internal registers is inserted into the H1 and
H2 bytes of the Transmit TelecomBus according to the STS1_PTR_SEL[12:1] bits. When
H1H2EN is a logic zero, the values from the internal registers is not inserted into the H1 and
H2 bytes. This bit has no effect when in SBI mode (TELECOM_BUS = ‘b0 in the Master
Configuration Register).
The STS1_PTR_SEL[12:1] bits select which of the two H1-H2 Pointer registers is used for
each of the 12 STS-1’s output on the Transmit TelecomBus when the H1H2EN bit is set.
When STS1_PTR_SEL[x] is a logic zero, the SBS Transmit H1-H2 Pointer Value register is
used for the associated STS-1 on the Transmit bus. When STS1_PTR_SEL[x] is a logic one,
the SBS Transmit Alternate H1-H2 Pointer Value register is used for the associated STS-1 on
the Transmit bus. These bits have no effect when H1H2EN is low or when in SBI mode
(TELECOM_BUS = ‘b0 in the Master Configuration Register).
