A Udio Port - Avaya 4600 Series Installation Manual

A UDIO Port

2 3 0 B
This port is found on the rear of all IP Office control units. It is used for the input of an external music-on-
hold sound source. Note that if the IP Office has loaded an internal music-on-hold sound file, any input
from this socket is ignored.
The port is a 3.5mm stereo jack socket suitable for use with the most standard audio leads and
connection to the 'headphone' output socket of most audio systems.
The use of a 'headphone' socket allows simple volume adjustment. Connection via a 'Line Out' socket
may require additional equipment in order to adjust the volume level.
