Tuner Menu

This menu enables the user to configure the tuner for operation. The terminal configuration of
the tuner is simple to perform and can be done at installation time.
Menu items <C>, <M> and <T> are described in detail on the following pages.
Fill Rate
This value should NOT be changed from the factory default setting
(1,000,000) unless the receiver is being used for low-latency traffic such
as VoIP traffic.
Comtech EF Data recommends modifying this parameter to improve
latency and jitter performance, to a setting greater than 5,000,000. The
actual setting will depend upon traffic and may need to be set on a per
case basis. The valid value range is 0 to 10,000,000, with the default as
1,000,000. VoIP traffic may require a setting between 5,000,000 to
10,000,000.
Setting the Fill Rate to 10,000,000 (the maximum setting) may lower the
overall performance (packets per second and bits per second) of the
product by as much as 10%, so care must be taken when modifying this
parameter.
