Command Set Controller SoftwareCommand set controller (CSC) software libraries include a general purpose CSC option for developers to support features offered by many command sets. These features include facsimile control (known as fax command sets class 1, 1.0, 2, 2.0 and 2.1), speech/audio coder control, speakerphone control, data modem control, caller ID, low-level multimedia control (V.80), V.8/V.8bis startup procedure control (V.251).

VOCAL’s Overall Modem Controller (OMC) Layer implements a command set independent modem. It can be used standalone (in systems that do not require command set control) or with the CSC layer. Our general purpose parse table structures can be customized for particular system requirements. Numerous command sets are already available (T.31, T.32, V.80, V.250 (V.25ter), V.253 (IS-101), EIA-615, industry standard, etc.).

VOCAL’s embedded software libraries include a complete range of ETSI / ITU / IEEE compliant algorithms, in addition to many other standard and proprietary algorithms. Our software is optimized for execution on ANSI C and leading DSP architectures (TI, ADI, AMD, ARM, MIPS, CEVA, LSI Logic ZSP, etc.). These libraries are modular and can be executed s a single task under a variety of operating systems or standalone with its own microkernel.  Contact us to discuss your modem application requirements.
