1. DESCRIPTION
1.0 Description
The DCB D56 modem is a 56 Kbps (V.90) dial-up modem. The modem
can be powered by an external AC wall mount power supply, or by an
optional internal 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 D56 modem include those industrial applications
where rack mounting is required, a metal enclosure is required, or
where the power source available is DC, rather than an AC wall outlet.
