13.6.2 Using Loop Modes for Troubleshooting
Loop Mode
This item allows the Zephyr Xstream to loop audio through the system.
• None
This is the normal operating mode. None of the loopback paths are turned
on. Studio Input is sent as send audio, and caller audio is presented at
Studio Out.
• V.35
This loops the incoming V.35/X.21 Receive data on each V.35/X.21 port back
out the Xmit data pins on the same port. NOTE: a valid external V.35 clock
is required.
• Audio
This loops the AES/EBU input (and analog signal inputs after Analog‐to‐
Digital conversion) back to the AES/EBU output (and analog output via the
Digital‐to‐Analog converter). With this mode engaged you can make signal
to noise, THD, and frequency response measurements through the system
to check the input and output stages.
