Condition	Result	Solution

Authentication		credentials to be reset. Trying to register a
(credentials)		modem after doing this will cause a
problem (cont.)		credentials error because the reset values in
		the modem do not match the values the
		MDIS has for that IP Address from prior
		usage.
		This problem is not likely when you are
		initially registering a new modem, unless
		the IP Address was previously used in your
		organization. If a credentials problem is
		indicated, contact the carrier to have the
		credentials for the IP Address reset.
		If you suspect that this occurred, use the
		AT-Zcommand (in service provider
		mode) to view the actual credentials. If the
		displayed credentials are zero, call the
		carrier to get the IP Address reset.
Flow control	Not	This condition is only possible if you are
problem	applicable	using manual registration (AT\R1) instead
		of automatic registration. If, after you key
		AT\R1 and press ENTER, the cursor returns
		to the A of the AT and the modem does not
		return an OK or an ERROR within the
		time-out period (S-Register 13) you likely
		have this problem.
		Flow control is only applied when the
		modem is in online mode or is interacting
		with the network in command mode (as it
		is when trying to register). Even if the flow
		control is set improperly, or has a cable
		problem that impacts flow control, you will
		not notice it until you try to register. The
		flow control setting defaults to hardware
		flow control, indicated by \Q2 in the
		modem profile, and this should match the
		COM port setting on your PC’s terminal
		emulator program. If the settings match try
		changing them both to no flow control
		(\Q0) on the DART. If registration now
		works then a broken or missing pin, faulty
		connection, or broken or missing RTS or
		CTS wire is the likely source of the
		problem.
