The Model 2350A Telemetry Gateway provides the necessary signal processing to pass telemetry data either to or from an Ethernet network. User programmability permits the unit to function as a Telemetry-to-Ethernet converter (packetizer) or as an Ethernet-to-Telemetry converter (de-packetizer). Each channel is individually configurable as either a packetizer or a de-packetizer.
The MD2350A is available in 6 and 12 channel configurations. Each channel accepts PCM data streams with associated coherent clocks. PCM data is captured and packetized into Ethernet packets along with header information. Packet size and buffering can be user selected or automatically controlled to minimize latency. The remote unit receives the Ethernet packets from the network and de-packetizes the PCM data. Using the statistics provided by the packetizer, the de-packetizer reconstructs the original PCM data stream and coherent clock. Input PCM data streams may be independent in content and rate. Up to 12 Channels are provided in the 1U Chassis.
In a typical application, the inputs to the packetizer are received from PCM sources such as bit synchronizers connected to telemetry receivers. (Optionally, internal bit synchronizers are available.) The data is then transported over the network to a remote unit. The de-packetizer function in the remote unit reconstructs the output clock and PCM data which can be directly connected to a PCM frame synchronizer / decommutator. Alternatively, the data can be sent over the networks to a remote processing unit. Frame synchronization and packet alignment in the packetizer simplify processing by a downstream software decommutator.
