Boston, MA, November 4, 1998 - Zoom Telephonics (NASDAQ: ZOOM), a leading producer of wide-area network solutions, today announced a line of feature-rich external ISDN terminal adapters with exceptional voice telephony and fax support.

All models feature two POTS (Plain Old Telephone Service) ports, each of which can handle up to five voice telephony devices, such as standard telephones, fax machines , and analog modems. In addition to POTS ports, the MX model features a V.34 faxmodem to provide interoperability with analog modems and fax machines around the world.

"With its V.34 faxmodem, the MX model brings a level of integration and interoperability that is unmatched in the market today."

Each product comes bundled with an easy-to-use point-and-click application that enables users to install and configure the device as well as the user's ISDN line. There are eleven LEDs on the TX and fourteen on the MX, for full status reporting of the ISDN line, the POTS ports, and the DTE port. In addition to the front panel LEDs, the application utility provides comprehensive ISDN diagnostic tools and troubleshooting advice.
