CPAS-5500 MITR – Ruggedized TAP Recorder


  • Over 1.5GB per second sustained record rate
  • Up to 24TB of RMM storage capacity
  • Simultaneous publishing up to 4Gbps from recording channels to 4 Ethernet switch ports
  • HDLC/Chapter 7 Encoded PCM Output for CH10 UDP Telemetering Transmission
  • Modular Data Channels: Fibre Channel, Ethernet, AS5643 IEEE-1394B, & More

The Modular Instrumentation Traffic Analysis Point (TAP) Recorder (MITR) is a high-bandwidth, high-capacity IRIG 106 Chapter 10 data recorder/publisher with a TAP Interface Module (TIM) & multiple Tera-Bytes of high-speed removable storage. MITR is suitable for a wide range of data recording requirements in harsh & demanding environments.

Configurable TIM’s provide protocol independent full duplex optical transceivers. Applications include Ethernet, Fibre Channel, InfiniBand, or any specific communication application. Input channels are recorded/published & mirrored outputs provide full active TAP capabilities.

MITR also contains a Layer 2/3 Managed Carrier Ethernet Switch with (4) external interfaces, a GPS receiver & IRIG Time Code Generator. The hardware based IEEE-1588v2 time engine provides multiple Grand Master, Master, Slave & Transparent clock capabilities.

The (4) external Ethernet interfaces can be used for IRIG 106 Chapter 10 data publishing, RMM download or as a fully capable Layer 2/3 Managed Switch. Switch ports can also be recorded or be used as a NAS/file server interface to one or more of the RMM drives.
