The CX29503 has three TSB Interfaces (see
The TSB interface provides for full duplex communication with external devices,
such as Mindspeed’s CX28500 HDLC controller, over two serial (1-bit wide) buses.
One bus, called the Payload TSB, carries payload data to and from the PDH framers
and SONET/SDH block. The other bus, called the Overhead TSB, carries overhead
data communication channels to and from the PDH framers and SONET/SDH block,
and it carries a device’s register content and command data passed between the
Command and Status Processor (CSP) and the local host processor.
