Connecting a Modem

If you need remote dial-in access to the command line interface (CLI), you can connect a modem (AT or Hayes compatible) to the CVX 600 using the DB-9 to DB-25 modem cable.

To connect a modem to the CVX 600, follow these steps:

Step	Action
1	Turn on the modem, then configure it using the parameters listed
	below.
	For instructions, see the documentation for the modem.
	Modem Parameter	Value/State
	Baud rate	56 Kb/s (or less)
	Auto answer	Set to n rings with DTR active.
		(The value n must be greater than
		0. If the value is 0, Auto answer is
		disabled.)

	Data terminal ready (DTR) signal	DTR signal fail-disconnect
		enabled. Return to command
		mode; Auto answer is disabled.
