Wideband Line Quality Monitor

During the course of a wideband call line quality on a telephone network can degrade, which can impact the clarity and overall audio quality of a VTX Wideband call. SoundStation VTX 1000s Wideband Line Quality Monitor will automatically revert a wideband call to narrowband mode if significant line quality degradation is detected, and is severe enough to impact wideband audio quality over time. The Wideband Line Quality Monitor is ON

by default, but can be deactivated by selecting OFF and then SAVE . For shorter conference calls, the benefit of turning off the Wideband Line Quality Monitor is

Administrator’s Guide

The ability for two SoundStation VTX 1000s units to connect in wideband mode is largely dependent on telephone line quality. The longer the “training” time (the time between when two VTX phones connect until a wideband call is established) the higher the probability two SoundStation VTX units can establish a wideband call, even on relatively poor quality phone lines.

SoundStation VTX 1000 assumes poor line quality by default, defaulting to a Long Training Time of 10 - 12 seconds. However, a Short Training Time can be configured on higher quality phone

lines, such as analog lines on enterprise telephone systems (PBXs, etc.), in order to save wideband connection time.

Training time can be decreased to 4

-6 seconds by selecting SHORT, then pressing SAVE to save the change.

If Short Training Time does facilitate consistent connections in wideband mode, return SoundStation VTX 1000 to LONG Training Time.

that it may be likely that your wideband call will end before any detectable degradation in audio quality can be detected, thus avoiding an unnecessary “drop” to narrowband.
