The OH1H2EN bit enables the insertion of the H1 and H2 bytes in the transport overhead on
the Outgoing TelecomBus. When OH1H2EN is a logic one, the values in the internal
registers is inserted into the H1 and H2 bytes of the Outgoing TelecomBus according to the
STS1_PTR_SEL[12:1] bits. When OH1H2EN 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 Outgoing TelecomBus when the OH1H2EN bit is set.
When STS1_PTR_SEL[x] is a logic zero, the OSTA Transmit H1-H2 Pointer Value register is
used for the associated STS-1 on the Outgoing bus. When STS1_PTR_SEL[x] is a logic one,
the OSTA Transmit Alternate H1-H2 Pointer Value register is used for the associated STS-1
on the Outgoing bus. These bits have no effect when OH1H2EN is low or when in SBI mode
(TELECOM_BUS = ‘b0 in the Master Configuration Register).
