5.6 RESPONSE ERROR CODES

All responses from the RTU-292 include an error code. This error code allows the user to see if there were any problems with a given command. Unless otherwise noted the user may assume that a non-zero error code indicates that the command was not acted upon.

	Table 5-4	Response Error Codes
E0	No error.
E1	The previous command is unknown.
E2	The previous command was missing required parameter(s).
E3	The previous command had a parameter, which was out of the allowed range for this command.
E4	The previous command requested a resource, which is not available. An example of this would
	be a DIAL command sent to the Local Phone option, when the Local Phone option is not
	installed.
E5	The previous command requested a resource, which is currently busy. An example of this would
	be a DIAL command received when the RTU-292 is already off hook.
E6	The previous command may not be used at this time. An example of this would be a DTMF
	command received when the RTU-292 is still on-hook.
E7	A hardware related fault was detected.
