4.10 V24/CTI Interface Module
4.10.1 Hardware description
4.10.1.1 Overview
The V24/CTI Interface Module allows a Data Terminal Equipment (DTE) to be connected to the OXO
Connect, via a UA link, by means of an RS232 serial link (CTI port) or a V24 link.
The V24/CTI Interface Module can be used alone or combined with Digital Premium DeskPhones.
CTI port
The RS232 serial link carries signalling (up to 9600 bit/s) and allows telephone operations such as call
management and call monitoring. The audio part is carried out by the associated dedicated set.
V24 port
The  V24  port  is  considered  as  a  DCE  and  provides  a  capacity  of  19200  bit/s  (ECMA  102)  for  an
asynchronous V24 transmission. The electrical interface complies with the V28 recommendation of the
CCITT.
