5 Data Communications
About Data and Video Communications
Calls to the group are distributed among group members in a circular pattern. The
system hunts for the first available modem or ISDN terminal adapter, starting with
the one that received the last call. If all group members are unavailable, the caller
hears a ringback tone.
Guidelines for creating DHGs are contained in "Creating Data Hunt Groups," later
in this chapter.
Data Hunt Group Configurations
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
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
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: NOTE: NOTE:
When using the 008 MLX or 408 GS/LS-MLX module for data or video, you
must use Version 28 of the module.
