Rack-mount Solutions
Multiple TDM Optical and Packet rack enclosure can house any combination of USB based test equipment- PacketExpert™ 10GX, tProbe™ (T1 E1), USB T3 E3 and Dual UTAs to support multiple interfaces in a compact rack space. Rack-mount systems not only provides space efficiency, but also account for easier scalability and reduced licensing cost per port.
1u Rack-mount is an enclosure, w/ or w/o Embedded PC. Scalability of Rack-mount solution can be achieved by stacking Rack-mount enclosure housing any of the USB based units with daisy chain connection. The daisy chain option allows to connect multiple Rack-mount solutions without embedded PC to a single Rack-mount with embedded PC, allowing all units to be controlled using a single software. This way multiple units can be stacked to accommodate more number of interfaces per system, and all controlled by a single software.
Rack-mount Solutions for TDM, Optical and Packet-IP network interfaces are briefly discussed.
