4-14
Payload TSBUS
Overhead TSBUS
Examples of the payload TSBUS operates at a data rate of 51.84 Mbps. It carries
the data path signals derived from either SONET, SDH, electrical DS3 or the
electrical E3 signals. The data on the payload TSBUS is framed and consists of 84
time slots.
Payload data paths are as follows:
Examples of the overhead TSBUS operates at a data rate of 12.96 Mbps. It carries
PDH or SDH overhead communication channels and carries the data monitoring
and data configuration for the device that communicates through TSBUS
interface with the CX28560. The data on the overhead TSBUS is framed and
consists of 84 time slots.
The sources and destinations of overhead data transferred to and from the
overhead TSBUS are as follows:
