Installing and Configuring the Driver using a Command (cmd) Prompt
When the install program installs the driver, history logging is
disabled by default (0). When you manually install the driver using
install, the default is set to disable history logging (which you can
choose to override). History logging is a powerful debugging tool,
especially when working with Dialogic Technical Services and
Support. However, it does consume a significant amount of CPU
time when running very high call loads. Therefore, leave history
logging off for systems that have high call loads and are CPU bound.
For low-load systems or when debugging, enable history logging (1).
Leave the number of physical and application channel histories at 0
unless you are directed to change this by Dialogic Technical Services
and Support. If you change the physical or application buffer size, do
not change the value to one smaller than the default.
If you specify a number for the physical channel histories, install
asks if you want to restrict the physical channels to administrative
channel 1.
Restrict physical channels to admin channel 1 (default 1):
Choose the default (enable).
If you select advanced configuration parameters, the software
prompts you for the number of I2O frames, driver flow control
interval, internal memory allocation parameters, module
reservations, and test parameters. Do not configure advanced
parameters except under the advice of Dialogic Technical Services
and Support.
When Dialogic® Brooktrout® PCI hardware modules are installed in
the system, a certain type of memory resource might be exhausted or
dangerously low if you do not perform a memory adjustment. For
small numbers of modules, the adjustment is often not required, but
there is no way to predict the point at which it becomes necessary,
since each system is different. Need for the adjustment depends on
the system configuration, whether other drivers or devices are using
