Zoom Telephonics Inc

Business Description

Zoom Telephonics designs, produces, markets, sells, and supports Internet access and other communications-related products including cable modems and gateways, mobile broadband modems, wireless routers, Multimedia over Coax (“MoCA”) adapters, Digital Subscriber Line (“DSL”) modems, and dial-up modems. Our primary objective is to build upon our position as a leading producer of Internet access devices sold through sales channels that include many of the largest United States (“USA” or “US”) high-volume electronics retailers, and to take advantage of a number of trends in communications including higher data rates, increasing use of wireless technology for transmission of data, and increasing use of smartphones, tablets, and streaming media.

Cable modem products, including both cable modems and cable gateways, were Zoom’s highest revenue product category in 2015 through 2017. Cable modems provide a high-bandwidth connection to the Internet through a cable that connects to the cable service provider’s managed broadband network. When a cable modem also includes a built-in WiFi router, it is called a cable modem/router or cable gateway. We began shipping cable modems in 2000. Our primary means of distribution to end-users in the US, our primary market, is through national retailers and distributors. We continue to sell cable modem products under the Zoom brand, and beginning in 2016 we started offering cable modems and gateways under the Motorola brand. In response to demand for faster connection speeds and increased functionality including improved WiFi performance, we have invested and continue to invest resources to advance our cable modem product line.

Our mobile broadband products provide or use a high-bandwidth cell-modem connection to the Internet through access to a mobile service provider’s mobile broadband network. These products target both the consumer and machine-to-machine (“M2M”) markets. Zoom has sold mobile broadband modems and routers in the past, and Zoom plans to ship a Motorola Ethernet cell modem, a Motorola Ethernet cell modem/router, and a Motorola multi-sensor in 2018.

Our DSL modems provide a high-bandwidth connection to the Internet through a telephone line that typically connects to compatible DSL equipment that is managed by the DSL service provider. In past years Zoom has shipped Asymmetrical DSL (“ADSL”) modems. Zoom plans to ship a new AC1600 gateway with both Very high bit-rate DSL (“VDSL”) and ADSL capabilities during the first half of 2018.

Our dial-up modems connect personal computers and other devices to the local telephone line for transmission of data, fax, voice, and other information. Our dial-up modems enable personal computers and other devices to connect to other computers and networks, including the Internet, at top data speeds up to 56,000 bits per second. Zoom’s sales of dial-up modems, our largest source of revenues from the mid-eighties through 2010, are expected to continue their decline due to the ongoing adoption of broadband access.

In August 2016 we extended our Motorola license to a worldwide exclusive license that includes cable modems and gateways, WiFi routers, WiFi range extenders, powerline communication devices, and related products. In August 2017 we further extended our Motorola license to a worldwide exclusive license for DSL modems and gateways, cellular modems and gateways, and MoCA products, and to a worldwide non-exclusive license for cellular sensors. We introduced under the Motorola brand two WiFi routers, one range extender, and one MoCA Adapter in 2017. In 2018 we plan to introduce under the Motorola brand one or more WiFi routers, a DSL modem/router, a cellular modem and modem/router, and a cellular multi-sensor.

We are incorporated in Delaware under the name Zoom Telephonics, Inc. Zoom Telephonics, Inc. was originally incorporated in New York in 1977 and changed its state of incorporation to Delaware in 1993. MTRLC LLC, a wholly owned subsidiary of Zoom Telephonics, Inc., is a limited liability company organized in Delaware that focuses on the sale of our Motorola brand products. Our principal executive offices are located at 99 High Street, Boston, MA 02110, and our telephone number is (617) 423-1072. Our Web site is at www.zoomtel.com. Information contained on our web site does not constitute part of this prospectus. Our common stock is traded on the Over-The-Counter market (“OTCQB”) under the symbol ZMTP.


The vast majority of our products involve communication of data through the Internet. Our cable modems connect to the cable-TV cable and our DSL modems connect to the local telephone line to provide a high-speed link to the Internet. Our mobile broadband modems and our coming mobile broadband routers and sensors connect to the Internet through a mobile service provider’s mobile broadband cellular network. Our dial-up modems link computers, point-of-purchase terminals, or other devices to each other or the Internet through the traditional telephone network. Our router products may communicate with a broadband modem for access to the Internet, and they may also be used for local area network communications. Our planned sensor products will connect sensors to users’ smartphones and Web browsers via a mobile broadband connection to the Internet.

Cable Modems

We have obtained CableLabs® certification for our currently marketed cable modems, and these cable modems have also received a number of cable service provider certifications. The lengthy, expensive, and technically challenging certification process has been and continues to be a significant barrier to entry.
