FULL DUPLEX SETTING

4.10.1

Full Duplex Setting for Terminals

Full-duplex mode for conversations allows both parties to talk and be heard simultaneously. All of the
UX5000 IP terminals are full-duplex and this cannot be changed. The UX5000 digital keysets are full-duplex
by default - except the 6-Button or 2-Button terminals which are half-duplex). If required, this setting can be
changed on the digital terminals to half-duplex mode. The following installation instructions can be used for
the Enhanced 12-Button or 24-Button, or DESI-Less terminals.
