Key Features

  • The TTESwitch A664 Pro (SMC) enables the implementation of critical network-centric applications. The high-performance switch enables packet processing on all 24 ports with full line speeds:

    • 6 x 10/100/1,000 Mbit/s ports
    • 18 x 10/100 Mbit/s ports
    • 1 additional mirroring port: 10/100/1,000 Mbit/s
  • The switch allows the configuration of up to 4,096 virtual links (VLs). Virtual links can be configured with 8 priorities and a bandwidth allocation gap (BAG) of 0.5 to 1,600 ms.

    The configuration of the network is stored in the switch’s non-volatile memory (256 Mbit). As an option, IEEE 802.1Q VLANs can be configured. Profiled IP/UDP, redundancy management and traffic shaping are implemented in the hardware. A built-in TMS 570 CPU is used for management and higher-layer protocol functions.

  • The built-in management module runs on a separate CPU. It allows for data loading as well as for querying the network status via SNMP. The data loading is done according to ARINC 615A-3.

    • 6 x 10/100/1,000 Mbit/s full-duplex Ethernet (via QSGMII)
    • 18 x 10/100 Mbit/s full-duplex Ethernet (via QSGMII)
    • 1 x 10/100/1,000 Mbit/s Ethernet Mirroring (via QSGMII)
