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.
Hardware Overview
There are eight (8) different devices that can be used in any Telestra installation:
1. Telestra : The processing platform itself
See “Telestra v3.0 User Guide” (DOC-01-TELS-UG-3) for full details.
2. Iris : The audio interface module where headsets and other I/O devices are attached.
See “Iris Audio Interface Module Technical & User Guide” (ASSY-01-UMAU-UG-1) for
full details.
3.
Axis : The local USB distribution module
See “Axis Local Distribution Module Technical & User Guide” (ASSY-01-UMLD-UG-1)
for full details.
4.
Prism : The USB extender module
5.
Spectrum : The remote USB distribution module
See “Prism & Spectrum Remote Distribution Modules Technical & User Guide”
(ASSY-01-UMRXRD-UG-1) for full details.
6.
1U Iris Extended and Local Options : The 1U Extended Iris is a 1U enclosure containing
one (1) standard Iris devices and one (1) Spectrum remote distribution module. The 1U
Local Iris is a 1U enclosure containing one (1) Iris devices and one (1) Axis local distribu-
tion module.
See “Iris Audio Interface Module Technical & User Guide” Appendix A (ASSY-01-
UMAU-UG-1) for the full details.

7. 4-Channel Iris : There are two 4-Channel Iris options. The 4-Channel Extended Iris is a
single 1U enclosure containing two (2) standard Iris devices and one (1) Spectrum remote
distribution module. The 4-Channel Local Iris is a single 1U enclosure containing two (2)
Iris devices and one (1) Axis local distribution module.
See “Iris Audio Interface Module Technical & User Guide” Appendix A (ASSY-01-
UMAU-UG-1) for the full details.
8.
6-Channel Iris : The 6-Channel Iris is a single 1U enclosure containing three (3) standard
Iris devices and one (1) Axis local distribution module.
See “Iris Audio Interface Module Technical & User Guide” Appendix B (ASSY-01-
UMAU-UG-1) for the full details.

USB Connector Types
In the following diagrams, connectors marked with an “A” represent standard USB type A plugs.
Connectors marked with a “b” represent miniature USB type B plugs.
Cables Suggestion
ASTi highly suggests using professionally-made, high-quality Cat 5 and USB cables. Our tests
have shown that most errors are the result of improperly constructed or poor quality cables.

Power-On Ordering Requirements and Lost USB Devices
The USB audio distribution architecture has specific requirements regarding the power on
sequencing of devices in order to achieve a working system. The Telestra processor system must
perform a discovery process in order to find all the devices that are connected, and hence this sys-
tem is started last in the sequence of elements. The discovery process runs as part of the system
framework boot process, or it is manually initiated from RMS, by clicking the “Hardware” tab,
and then the “Reset USB network” link. Prior to this all other elements of the USB sub-system
must be connected, and powered on.
Note that the Prism/Spectrum extender architecture should
be powered on before or simultaneously with the Iris audio interface units.
If any element of the USB sub-system is powered off and then back on again without rebooting
the Telestra processor, or initiating a manual USB discovery, then the result will be that those
devices are “lost” to the system, and will no longer process audio. The most effective way to
check for this condition is to look at the RMS system, select the “Hardware” tab, and then the
“Layout” tab. Any Iris units that were connected at the time of system boot and have been subse-
quently powered off will show up with a red ‘X’ through the device. If profiling is turned on (see
Telestra 3 User Guide for details), then any device that is not active on the USB sub-system will
be reported with a red ‘X’. To recover from this situation, power on the required USB devices
(Prism devices first, Iris devices last), and then either reboot the Telestra, or initiate a manual USB
re-discovery using RMS. If using RMS, once the re-discovery process has completed, it will be
necessary to reload the model.
