Synapse Installation Guide
MoH is not playing and the
AUX IN LED is GREEN.
MoH not properly configured.  Verify that the audio source is playing and not muted.
 Set the MoH output volume level by adjusting the playback
volume of the music source device connected to the ATA.
You may need to set the volume near the maximum.
 Some MoH sources without volume controls, such as
those with audio-out jacks, are usually very loud and
might be too loud.
 Synapse limits the volume of the sound delivered to the
phone line. Because of this, there may be audio clipping
(missing sounds) for some sources.
 Some forms of music do not play well over a telephone
line.
 Verify that the audio source meets the electrical
specifications for ATA AUX IN. See “Appendix A: Technical
Specifications” on page 202.
 Verify that Hold Announcement is not playing a silent
message.
