DESCRIPTION

The DV-1D data and voice multiplexer from DCB makes it easy to combine voice and data over a single 56/64 Kbps digital link. The DV-1D includes the DSU/CSU, one digital channel and one voice channel. The digital interface can operate at 9600, 19,200 or 38,400 bps and includes both an RS-232, RS-530, or RS-422 interface. There are two modular connectors for the voice line interface, one 2-wire and one 4-wire. One of the 2-wire voice interfaces provides for connection to a telephone, the other to a PBX station line. The 4-wire interface is E&M for PBX tie line operation. A second RJ-48S connects to the digital link.

The DV- 1 is priced right, making voice an affordable choice any time you are installing a data line between two locations. The DV-1D pays for itself in two years or less versus the cost of a business line at each end of the link. If you have any long distance calling, the DV-1D typically pays for itself in a few months. The DV-1D is always the right choice.

The voice channel can be used to connect remote office key systems together, to connect PBX's together, or to provide a remote PBX extension. In key system applications, the voice line will appear as one of the line selections on a key telephone system. The 4-wire E&M interface is used to connect PBX systems together using a tie line. PBX station lines can be extended to either a single line telephone or a key system at a remote location. Both loop start and ground start lines are supported.

The DV-1D has an internal 56/64 Kbps DSU/CSU. It has standard diagnostic loopbacks, self test, local test, remote test and data interface LED indicators. The data interface can operate either sync or async.

The DV-1D is ideal to use with the DCB SR or SPL multiplexers and routers. Together they give you the lowest cost, highest performance combination of voice, DSU/CSU and statistical multiplexing or routing. Dynamic bandwidth allocation supplies more bandwidth to the data interface when no phone call is taking place. With the DV-1D you can now afford to add voice to every point to point statistical multiplexer link.
