employing a variety of visual aids, including interactive writing and drawing, prepared text and graphic materials, and prerecorded audio and video material. You can have all the advantages of face-to-face meetings while decreasing your travel budget.

Group video systems that support ISDN/BRI interfaces have built-in data communications devices and can use one MLX B-channel or two (depending on the system), requiring only a single MLX jack and the system’s 2B Data feature.

Older group systems that support a V.35 interface may also have built-in data communications devices; if not, they require two Lucent Technologies-certified ISDN terminal adapters, or an inverse multiplexor and two MLX ports. V.35 systems use two adjunct extension numbers.

Most group videoconferencing applications include an easy-to-use control console that allows you to conduct the conference as easily as you operate a telephone. It includes superior camera optics and digital audio signals.

The components of a group video system can be integrated on a mobile console that rolls easily into a conference room prior to a scheduled video conference call. Alternatively, some companies build their systems into a videoconferencing room.

CTI (Computer Telephony Integration) Link 5

Beginning with Release 5.0, the system supports the CTI (Computer Telephony Integration) link, which allows the use of software applications with the system. Although the CTI link is not, strictly speaking, a feature, it enables considerable feature enhancement to the system. Available in Hybrid/PBX mode, this capability connects the system to a PassageWay Telephony Services product on a local area network (LAN). The link is made through a programmed MLX extension jack that is connected to an ISDN BRI PC expansion board (such as the EICON board) on a server running Novell NetWare software, version 3.12, 4.11, or 4.1.

The CTI link allows calls on SA buttons to be monitored and controlled from client workstation applications connected on a LAN to the server. The link can support LAN workstations with analog BIS (ATL) multiline or MLX telephones, not single-line telephones or analog membrane telephones. The link allows worktop applications to control their associated telephones. QCC operator extensions cannot use CTI link applications, but DLC operators can. Only one link is necessary, and it can support up to 136 LAN clients, depending upon the types of extensions (analog or MLX) and the volume of calls handled by the software applications.

Incoming calls on SA buttons may arrive through calling group distribution, PRI routing by dial plan, DID (Direct Inward Dial) lines/trunks, or transfer from a DLC or QCC operator or automated attendant.
