CHAPTER 4 BOARD AND SYSTEM CONFIGURATION
This chapter describes the configuration of the Cyclades-PC400. After the general instructions, guided ex-
amples are provided to assist in parameter selection. Read the example closest to your application if in doubt
as to the best value for a parameter.
STEP ONE
If the PC400 driver was compiled as a module and it is desired that the driver be autoloaded when a PC400
device is accessed, add the lines below to /etc/conf.modules (or /etc/modules.conf, depending on
the Linux distribution used):
alias char-major-214 pc400
alias char-major-215 pc400
IMPORTANT: the Cyclades-PC400 driver must be loaded before the device is used.
STEP TWO
Next, create a text file to store configuration variables or edit the default configuration file, /etc/cyclades/pc400/
pc400.cfg.. Only one label and one value per line, with a space between the label and the value. Blank lines
are allowed. Examples are shown later in this chapter. The parameters are grouped into blocks and applied to
each interface/channel/logical link/profile as will be seen below.
• General parameters define the user interface, name and password, together with some general options.
• ISDN-PRI profile parameters set trunk information such as telephone numbers and connection type for
up to five profiles.
• DSP profile parameters set the string to be sent to the SAP for up to five profiles.
