Configuring DTCs Step-by-Step
Modify the Network Management Configuration File
In determining how many PAD connections to allow,
keep in mind that PAD connections use SVCs, out of the
pool of available SVCs. The same pool of SVCs is used
for system-to-system connections if system-to-system
connections are also configured for this card. You will
need to balance your PAD support requirements with
you system-to-system requirements to find the
optimum configuration for your network.
