Delay Limit
– The inverse of the
Delay Cushion
, this parameter instructs
the manager not to wind the buffer out beyond a certain delay value,
regardless of how many packets are lost. This is useful in applications
where staying below a certain delay figure is essential, but use of the delay
limit can result in very poor performance if the network jitter dramatically
exceeds the limit.
Fixed Delay
– This option simply sets the
Delay Cushion
and
Delay
Limit
at a similar value, so that the delay buffer is defined to the chosen
value and will not increase or decrease significantly.
Buffer Management On/Off
– This option is available only as a
troubleshooting tool. Turning the manager off will result in eventual
failure, since the manager is required to compensate for clock skew
between the encoder and decoder.
The
System Settings Tab
defines parameters that are not specific to a
particular remote connection. Examples are how incoming (POTS and IP)
calls are handled, global modem settings, and how the contact closures are
assigned. The
System Settings Tab
is shown in Figure 26a.
