DV/IP base stations are designed to interconnect directly with any TCP/IP network, including the Internet. However, in some private land mobile systems, it is not desirable to utilize the Internet for inter-site networking. In such instances, DWC's DNR Network Router becomes the hub of a DV/IP network.

Using Intel Pentium processors, and executing DWC's DV/IP operating system, the DNR Router serves as a local, regional or wide area controller. The Network Router can store digital audio, forward it to a remote DV/IP Network Router or DV/IP base station, and control and monitor a large number of co-located base stations.

The DV/IP DNR Network Router connects to DV/IP Base Stations by way of 10BaseT Ethernet using RJ-45 connectors.

The DNR is powered from 13.6 VDC, is constructed in a rack-mounted, industrial grade chassis, and features a front panel LCD liquid crystal display with florescent back light. The display provides a maintenance technician with operation and test information. A standard PC keyboard may be plugged into the front panel keyboard connector for testing purposes.

Two DNR Routers may be connected to the same 100 Base T LAN to provide a fully redundant multiple Network Router. Single or dual Ethernet busses may be used. A Network Router can directly support any number of DV/IP dispatch consoles and desktop Dispatch Workstations.
