Complete Communications Engineering

56K Modem Software supports real-time multichannel applications. The embedded 56K softmodem libraries are modular and can be executed as a single task under a variety of operating systems or standalone with its own microkernel. Contact us to discuss your modem application.

VOCAL’s 56K modem software is optimized for performance on leading DSP architectures and processors from TI, Intel, ADI, ARM and other vendors. Our modem software may be licensed standalone, as a library or complete design. Custom solutions are also available to meet your specific 56K modem requirements.

Virtual Modem over IP

VOCAL’s SIP Software modem (MoIP or V.MoIP) solution provides developers a range of solutions to connect legacy dial up modems to modem infrastructure. Unlike other virtual modem designs, the SIP software modem can communicate with a physical modem at the far end using a VoIP service over an IP network.

56K Analog Digital Modem

Features

Configurations

As per terminology above, three 56k modem system configurations are relevant: systems that implement an analog modem only, systems that implement a digital modem only, and systems in which the modem can take on the role of either an analog or digital modem.

Depending upon 56K modem configuration selected, the line interface may be an analog front end (codec and DAA) or a digital interface such as T1/E1, switched 56 and ISDN. The upper end of this software can provide PPP, V.14, HDLC or direct binary framing layers. Higher data protocol layers, V.42 (including MNP 2-4), V.44, V.42bis and MNP5 are options as well.

The 56K modem modulation family can be combined with other data modulations (V.92, V.34, V.32bis/V.32, and V.22bis/ V.22/V.23 V.21). V.8/V.8bis startup procedures can be used. All data modulation software is fully compatible with VOCAL’s facsimile, telephony, speech coder and multimedia systems.
