Introduction
ASTi's Telestra product line includes a variety of USB-based digital audio and input/output (I/O)
distribution equipment. USB connections originate at the Telestra processing platform, and even-
tually terminate at one or more Iris audio interface modules. The installation and connection of
intermediate devices will vary depending on the required distribution of these Iris devices.
This document addresses which types of connections are supported (and which are not). Where
connections
are
supported, maximum cable lengths and connector types are highlighted.
For the sake of clarity, this document uses the word “upstream” in reference to devices that are
closer to the Telestra system in relation to other “downstream” devices.
ASTi’s USB interface is based on the industry standard USB 2.0, but has been optimized for use
with this product line.
WARNING: Do not connect commercially-available, standard USB devices to the USB ports on
the Iris, Axis, Prism or Spectrum devices. This may cause damage to these devices.
