5.2.  Demo Options

To specify certain options at run-time, launch the demo from a command line, using any of the switches listed in Table 1.  Command Line Switches.

Table 1.  Command Line Switches

Switch	Action	Default
-c <filename>	Configuration file name	gateway_r4.cfg
-d	Sets Debug Level (0-4): 0-FATAL: used when one or more channels are deadlocked. 1-ERROR: used when the application receives a failure which doesn't cause the channel to be deadlocked. 2-WARNING used when some problem or failure occurred without affecting the channel's usual action. 3-TRACE used at the start of the application entrance or the start of any function. 4-INFO prints data related to a specific action. NOTE: Debug level is inclusive; higher levels include all lower levels.	0 - FATAL
-f	Identifies the front end: 0 = analog 1 = digital T-1 2 = digital E-1	0
-h or ?	Prints the command syntax to the screen	Off
-l <n,...>	Printouts will be printed into channel log files. If `all' follows the --l, log files will be created for all available channels. If a list of channels in the following format: C1-C2, C3-C4, C5 (e.g., 1-10,112-150,314) follows the --l, log files are created for the channel ranges or specific channels specified in the list. If "--l" option is not used all prints go to the stdout, for the first 2 channels only (to keep from overloading the CPU, and more convenient for viewing printouts).	Disabled
-n	Sets the number of channels	The lesser of PSTN Devices and IP Devices
-p	0-Disable dialing 1-Enable dialing Used for testing purposes, or if running the demo on a machine that does not have all of the necessary external connections	-p1
-q	Enables the Quality of Service feature	Disabled
-r	Sets the number of rings before answering the call on the PSTN	2
-s	0-Disable DNIS 1-Enable DNIS Used for testing purposes, or if running the demo on a machine that does not have all of the necessary external connections	0
