The D-Series is an industrial dial-up 56 Kbps V.90 modem. The modem can be powered with an external wall mount power supply, or can be powered by a 12, 24, or -48 volt dc supply. A rack front is available for the metal case, so it can be easily rack mounted with one, two or three modems per 1U rack height.

Applications for the D-Series modems include those industrial strength applications where a rack mounting is required. a metal enclosure is required, or where the power source available is DC, rather than an AC wall outlet. It is ideal for telco installation, SCADA remote sites, or ISP POP locations.

These are not repackaged consumer grade modems. Designed from the ground up for our industrial customers, they are also more reliable on marginal phone lines than commonly used "retail store" modems.
