Appendix J. RETURN GROUP Q
Figure 6-21 shows the appearance of this page when QoS is disabled (i.e., use the QoS Control
Mode drop-down list, available in the Add/Change/Delete Group section of this page, to select
Off, and then click [Submit]).
The top portion of the QoS page provides common functionality for all QoS modes. The bottom
portion of this page changes depending on the active QoS Mode. All commonality / differences
in page appearance between QoS Modes is noted accordingly.
Comtech EF Data strongly recommends that you do NOT operate the CDM-840
with QoS Control Mode = Off. When QoS Control Mode = Off there is no traffic
shaping or filtering. All data coming into the modem will be sent to the WAN as it
is received, in the order it was received, for so long as the WAN can support the
packet/frame and data rate of the incoming traffic. If there is not enough WAN
capacity to support the incoming traffic, packets or frames are tail-dropped as they
overflow the internal buffer.
