Anti-Stream
The A
NTI
-S
TREAM
option is used to select the anti-stream time-out.
The anti-stream time-out is the maximum time the DSU III AR
transmits data into the network from the DTE. This feature
prevents one DTE device on a multi-drop network from
continuously tying up the transmit circuit back to the master DSU.
Figure 6-8 shows the menu path used to access the
A
NTI
-S
TREAM
options menu.
The anti-stream timer is reset to zero when RS changes to the active
state and is updated every second while RS is active. When the
anti-stream time-out expires, the DSU III AR stops transmitting
DTE data into the network but continues to accept data from it.
This condition exists until the DTE deactivates the RS input.
The factory default setting is T
IMER
