The Model 2350 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). The Model 2350 is a rack mount unit and accommodates one or two modules. The Model 2351 is a table-top unit that accommodates a single module. Modules can be mixed and matched as needed. Each channel on a module is individually configurable as either a packetizer or a depacketizer.
The Model 2350 is available in 2 and 4 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 depacketizes 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.
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.
