Configuring Template Options
a. You may enable or disable Multilink support. Once you have enabled Multilink, the
following Multilink parameter will take effect.
b. Enter the Multilink Minimum Fragment Size. When transmitting data over multiple
channels, the normal algorithm is to divide the original packet into proportional fragments
for transmission over all the channels in the group. This option dictates a minimum size for
the fragments, with the intent being to avoid the transmission of very small fragments. The
parameter is actually expressed as fragment transmission time, in units of .1 milliseconds.
For example, a minimum fragment size of 64 bytes on a 64,000 Kbits/second link would be
expressed as 80 (64bytes/(8000bytes/sec) = 8 msec ==> 80).
Note: The reduced processing burden due to avoidance of small fragments comes at the
potential expense of wasted bandwidth, since some channels may be left idle when
transmitting a packet.
CONFIGURING CALL CONTROL INFORMATION
This section shows you how to configure call control information for the site template. The screen
below shows the default call control configuration.
1. Enter the Call Interval value (in hundredths of seconds). This is the minimum time between call
attempts. The site’s systems will not make a call attempt in less than the configured call interval
value. However, due to the system clock resolution, the actual time interval may be greater
than the configured value. The default value is .70 seconds. The range of the configured value
is 0 to 5 seconds, in 1/100 second increments. A configured value of 0 implies that the system
will make call attempts without any delay between attempts.
