CALISTO Host API
- Data synchronization
- Data pumps: V.34 33600 bps, V.32bis/V.32 14400 bps,
Reference design platform and training is available for
testing and customization projects.
The CALISTO Host API is a C-language, re-entrant library that
lets multi-threaded applications control CALISTO and
SpiceBridge devices. The library is implemented in the ANSI
standard C programming language, and is protected from the
underlying operating system by an OS abstraction layer.
provides the flexibility to add to and to expand the API as
capability is added to CALISTO, or when new hardware devices
become available.
•
V.22bis/V.22 2400 bps
• Signaling relay: DTMF, MF-R1, Type 1 Caller ID, and
CPM/CPG
• Robust API
Users can place the library objects into tables maintained by call
management applications, or add system-specific data to the
objects so that they themselves become the table entries. The
objects encapsulate addressing and state data to provide a flexible
and scalable data organization.

CALISTO Architecture
The library can be ported between operating systems and host
platforms. As a library, the CALISTO Host API always executes in
task contexts provided by the application software.
• 21 processing units per chip: 16 SpiceEngines™ and 5 RISC
processors
• 8 physical interfaces: 2 TDM ports, 2 SpiceBus ports, SDRAM
port, JTAG port, SPI serial boot port, and PLL port
• 19-mm, 239-ball ceramic fine-pitch BGA
• Reconfigurable-adaptive instruction sets
• Over 3.3 GMACs of signal processing power
The CALISTO Host API allows users to embed CALISTO and
SpiceBridge products into custom hardware architectures. The API
provides C language software objects that correspond to the
hardware components, and can be tied together to reflect the
architecture of the custom system. The object-oriented design
The object-oriented approach also lets the API manage state for
related objects. If users reset a CALISTO, all Channel Socket
Objects associated with the CALISTO change state as well. This
encapsulation assists users in managing connections, and in
implementing a hot backup redundancy scheme.
