BSS BLU-HIF VoIP Digital Phone Telephone Headset Interface

The BSS Audio BLU-HIF Telephone Headset Interface facilitates connection of the headset jack of a VoIP/digital phone to an AEC input and analog output of a Soundweb London device. The BLU-HIF therefore allows the VoIP/digital phone to be used as the dialing interface and hybrid for a conference system. This simple interface eliminates the programming requirements associated with third-party control systems, while providing a familiar and low-cost dialing interface to the end user.
The BLU-HIF features an RJ-22 jack for connection to the headset jack of a VoIP/digital phone, a balanced input (Tx) for sending near-side audio, and a balanced output (Rx) for receiving far-side audio. While the BLU-HIF provides substantial isolation of the Rx and Tx signals, near-side audio will still be heard on the Rx channel due to the presence of side-tone. As such, BSS Audio recommends always feeding the Rx channel to an AEC input, as opposed to a standard analog input. The AEC algorithm will remove the side-tone. The Tx channel connects to a standard analog output.
