Stat Mux Data
Statistically-multiplexed data contains the message itself—a part of a news story or
weather report—along with overhead information about the message, such as its
length, its origin, and its destination. Destination information directs data to a
specific logical receiver within the IDR V1000.
Logical Receivers
Stat mux operation has the capability of addressing messages to virtual, or logical,
receivers within an IDR V1000. A serial output port is automatically assigned to
each logical receiver. In stat mux mode, the CPU’s TDD partition of the data
stream can address all asynchronous output ports (Serial 1 through 4).
Most of the IDR V1000 status screen displays relate to statistically-multiplexed
packets and their destinations to one of four logical receivers within the IDR V1000.
Data handling in stat mux mode is more flexible than the transparent pass-through
data handling that occurs with transparent synchronous or asynchronous data.
Figure 5-2 and Table 5-1 specify the data stream processing destinations handled by
software within the IDR V1000.
TA = transparent asynchronous data
L1 = stat mux data
