IBM 2283, 6274 manual Symptom, Action

Symptom		Action
General	1.	Make sure the telephone cords are connected correctly
modem/communication		and securely. Connections for a standard modem are
problems.		shown in “Disconnecting cables” on page 36. If you are
		using other communication devices in conjunction with
		the modem, such as an asymmetric digital subscriber
		line (ADSL) adapter or home networking adapter, refer
		to the documentation for those devices to ensure the
		cords are properly connected.
	2.	Make sure the telephone line works. If you have a
		telephone connected to the modem, try making a call. If
		you do not have a telephone connected to the modem,
		plug a telephone into the same telephone outlet that the
		computer is plugged into (remember to reconnect the
		computer to the telephone outlet after verifying that the
		line is working).
	3.	Make sure you are calling the correct number and that
		you are using the correct communications settings. For
		additional help, refer to the documentation for your
		communications software.
	4.	Make sure no one else is using the telephone while you
		are communicating with another computer.
	5.	If you have Call Waiting, make sure it is disabled.
	6.	If some communications programs work but others do
		not, there might be a configuration problem. For
		additional help, refer to the documentation for your
		communications software.
	7.	Make sure your modem cord is attached to an analog
		telephone line. The local telephone company can
		determine the type of telephone line.
	8.	Make sure the modem is securely installed inside the
		computer. (See “Removing the rear cover” on page 37.)
	If these actions do not correct the problem, run the
	diagnostic programs (see “Running the IBM Enhanced
	Diagnostics program” on page 66). If you need technical
	assistance, see Chapter 7, “Getting information, help, and
	service,” on page 69.
