Unidirectional Broadcast Mode Applications
The unidirectional broadcast mode enables a user at a central location to send
data to multiple users connected to remote Megaplex units (simplex
communication), while using only one timeslot.
In this mode, any message is simultaneously received by all the unidirectional
users, but none of them can send back data to the originator.
This capability is achieved by separating the handling of the receive and transmit
paths in the timeslot assigned for the unidirectional channels, as shown by the
dashed lines within the Megaplex units in
Figure
1-3.
Figure
1-3
shows a network that uses the unidirectional broadcast mode to
distribute data from a central location (A) to several remote locations (B, C, D,
etc.). In
Figure
1-3
,
the user at the central location (A) is connected to an HS-RN
channel configured for operation in the unidirectional transmit mode. The
channels of the remote users (at locations B, C, D) are configured for the
unidirectional receive mode.
