The NEW Model MD2355-M16 is a Gateway unit that acts as a PCM to Ethernet (packetizer) or Ethernet to PCM (de-packetizer) converter utilizing our new web-based Browser GUI internal to our chassis. The MD2355-M16 is a 1U rack mount unit gateway that facilitates the transfer of data, which can originate from a variety of sources to and from a digital Ethernet network. The basic input is a digital data stream and its coherent clock. This serial data source is packetized, placed in an Ethernet wrapper, and output to a network environment. A second model MD2355-M16 or our legacy MD2350-(M02, M04, M12) can be connected to the network to receive and extract the original data from the Ethernet packets. This reconstructed data stream is output with a coherent clock at the same data rate as the original source. Each channel can be independently configured as PCM serial clock & data or Ethernet packets depending on your application. A typical application would have the inputs to the MD2355-M16 originating from a PCM source such as a Receiver with an inherent bit sync or a separate independent Receiver & bit sync configuration. Data I/O can be configured as TTL Data & Clock or RS-422 Data & Clock with each one of the sixteen channels assigned as input or output. This compact high-density transport solution will bring down the per/channel costs while increasing the system mean time between failures (MTBF).
