2.6 SI-Bus Interface
This section describes the system interface the CX29600 uses. This interface can
transfer payload data derived from either SONET or SDH data streams. The
SONET terminology for various rates and formats is used with the corresponding
SDH terminology following in parenthesis.
The SI-Bus transfers three complete, interleaved STS-1s with three separate start
of frame syncs.
SONET(SDH) data between a CX29600 device and several slave devices. By
definition, receive data flows from the CX29600 to the slave and transmit data
flows from the slave to the CX29600. Clocks and alignment controls flow from
the CX29600 to the slave in both the transmit and receive directions.
clock. Transmit and Receive 51.84 MHz clocks are generated for slave devices
thtat require STS-1 bit rate clocks.
The SI-Bus interface is capable of full-duplex, bi-directional transmission of
It operates at the nominal octet data rate of 19.44 MHz and has a continuous
