Direct Connect
The following information applies only to V.35 Direct Connect
setups.
Direct Connect users can choose to have the local system answer a
video call when it detects data from a remote site, or hang up when
it detects lack of data from the remote site. This Direct Connect
signal lead would be in addition to existing V.35 signal leads that
control answer/hang up call states. A description of the use of these
signals can be found in the Integrators’ Reference Manual for
ViewStation EX, ViewStation FX, and VS4000.
Setting up Satellite (H.331) Broadcast Mode
The ViewStation EX with a V.35/RS-449/RS-530 network interface
support H.331 broadcast mode for broadcast transmissions via
satellite. In this mode, your system sends and receives audio and
video without handshaking with the far-site system or
H.331-compatible systems.
One system can send video and audio to many systems or other
H.331-compatible systems, such as large satellite network.
Broadcast configuration parameters should be set to accommodate
the lowest common denominator of the systems which are receiving
the broadcast. For example, if one system in the conference supports
H.261 only, broadcast should be set to H.261 to ensure all systems
participate in the conference.
To access the Broadcast Mode screen:
1. Enable Broadcast Mode Setup in the Video Network screen
(System Info > Admin Setup > Video Network > Video
Network
). The Broadcast Mode Setup satellite icon appears.
