Data Hunt Group Configurations	5

The following DHG configurations work on the system:

■ISDN Terminal Adapters. Allows communications with the local host computer or a workstation (gateway) to a LAN.

■Modems. Allows communications with the local host computer or a workstation (gateway) to a LAN.

Video Systems 5

A video system is a hardware configuration that provides video teleconferencing. The video systems use both B-channels (2B Data) associated with an MLX port to achieve data rates of up to 128-kbps when using PRI or NI-1 BRI facilities, and 112-kbps when using T1 Switched 56 facilities.

There are two basic types of video teleconferencing:

■Personal Video Conferencing. This type, also referred to as Desktop Video Conferencing, typically is a single user communicating with another individual using their PC.

■Group Video Conferencing. This type, as the name implies, allows larger groups of people to communicate with another group at a different location.

Personal Videoconferencing 5

A personal videoconferencing system typically consists of a video camera and an audio unit connected to a PC. The PC connects directly to any available MLX port on a 408 MLX or 008 MLX module by way of a BRI interface card.

NOTE:

When using the 008 MLX or 408 GS/LS-MLX module for data or video, you must use Version 28 of the module.

The MLX port must be configured as a 2B Data port in order to provide the necessary high-speed data connection needed to support video applications. The network facilities used by the endpoint connected to the MLX port may be PRI, T1 Switched 56 (both provided by the 100D module), or NI-1 BRI (provided by the 800 NI-BRI module) facilities.

NOTE:

Some applications also provide data and application sharing and transfer capabilities (video collaboration) in addition to video conferencing.

This configuration, in which the personal video system is the only device connected to the MLX port, is called the Standalone configuration. Some personal video systems also offer the capability to support a Passive Bus configuration. See Figure 5–6 on page -18 for a sample connection diagram.
