Register 0202H, 0282H, 0302H and 0382H: RHPP Payload Configuration
In the normal mode of operation of the S/UNI-2488, this register must not be changed from its
default settings. In the cross connect mode of operation (controlled by the XCONNECT register
bit), the RHPP must be configured to correctly process the various payloads that are input to the
S/UNI-2488.

The STS-3c (VC-4) payload configuration (STS3C[1]) bit selects the payload configuration.
When STS3C[1] is set to logic 1, the STS-1/STM-0 paths #1, #5 and #9 are part of an STS-3c
(VC-4) payload. When STS3C[1] is set to logic 0, the paths are STS-1 (VC-3) payloads. The
STS12C register bit has precedence over the STS3C[1] register bit.
The STS-3c (VC-4) payload configuration (STS3C[2]) bit selects the payload configuration.
When STS3C[2] is set to logic 1, the STS-1/STM-0 paths #2, #6 and #10 are part of an
STS-3c (VC-4) payload. When STS3C[2] is set to logic 0, the paths are STS-1 (VC-3)
payloads. The STS12C register bit has precedence over the STS3C[2] register bit.
