BSS BLUHIF Soundweb Telephone Headset Interface

The BSS Audio BLU-HIF Telephone Headset Interface facilitates the 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 standard analog output.

The wiring configuration within the headset jack of a VoIP/digital phone often differs, depending on the manufacturer. The BLU-HIF comes with two cables whose 4P4C RJ-22 connectors are compatible with the two most common wiring configurations found in the headset jack of VoIP/digital phones.

The additional 2.5mm jack facilitates the connection of two-way communication devices such as cellular phones to the Soundweb London device. This gives the end-user the advantage of having an alternate communication path to the outside world, which is particularly useful as a backup to the main phone system.
