Modem & Fax Software

As products become obsolete and unsupported, hardware begins failing, and telecom providers continue to remove copper POTS lines, VOCALs modem solutions prove to be vital for maintaining a base of legacy devices.

VOCALs feature rich modem stack includes support for standardized ITU-T modulations and error correction protocols configurable via industry standard AT commands or direct software interfaces making it a drop in replacement for many existing modem applications and easy to integrate into any new product designs.

The flexible nature of the software based modem stack allows VOCAL to create end-to-end data modem solutions. Solutions for remote modems include embedded modem software to enable communication over legacy connections and Analog Modem Adapters to enable adaptation to modern wired and wireless networks. Solutions for central sites include the SIP Analog Modem Server (SAMS) for deploying a VoIP aware modem server and ITU-T V.150 enabled gateways.

VOCALs modems are used throughout commercial, industrial, and government sectors for applications including utility meter reading, environmental monitoring, medical devices, data gathering, secure phone communications (STE, STU), Point of Sale terminals, industrial SCADA (PLCs, RTUs), Remote Access Servers (RAS), alarm panel notifications, paging terminals, building automation and management, and Out of Band monitoring, configuration, and updating.

The grandfathering period for the FCC’s forbearance order is quickly approaching its end. Starting August 2nd 2022, telecom carriers that provide copper POTS lines are no longer required to maintain or repair that infrastructure. Existing applications that utilize analog voice, data, and facsimile services will no longer function correctly when this infrastructure is removed. SAMS is a key component in maintaining critical legacy services through this sun-setting process.
