4.0 Registers
4.1 Registers
0x10—TXK1 (Transmit K1 Overhead Control Register)
The TXK1 register controls the K1 byte in the transport overhead. The K1 and K2 bytes are allocated for
Automatic Protection Switching (APS) signaling between Line level entities. These bytes are defined only for
the first STS-1 of the STS-3c signal.
0x11—TXK2 (Transmit K2 Overhead Control Register)
The TXK2 register controls the K2 byte in the transport overhead. The K1 byte and bits 0-5 of the K2 byte are
allocated for Automatic Protection Switching (APS) signaling between Line level entities. These bytes are
defined only for the first STS-1 of the STS-3c signal.
These bytes are defined only for the first STS-1 of the STS-3c signal.
4-60
Bits 6-8 of the K2 byte are allocated for Alarm Indication Signal (AIS) and Remote Defect Indicator (RDI).
