SCbus Connectivity Paradigm
SCbus (Signal Computing) bus is an open architectural specification for digital intra-node communication. SCbus is a high-capacity bus with up to 2,048
time-slots, which will handle most audio/video applications. By using the SCbus connectivity paradigm, you can focus on other application issues (such as resource allocation) instead of complex connectivity problems. Each SCbus-compliant product provides virtually the same software interface to its given resource(s). Another advantage of developing with SCbus is consistency among compliant products.
While describing the SCbus characteristics in general, this section covers GDK SCbus-specific topics and introduces the SCbus Application Program Interfaces (APIs) for the CP Fax SC boards. Because of SCbus requirements, each compliant product must assign each of its resources to an unchanging and permanent transmit timeslot on the bus. The procedures to "nail up" transmit timeslots for its fax channels are described in detail at the end of this section.
