Call disconnects immediately after an attempt to connect; NO CARRIER may be displayed on the local terminal device; CHECK SPEED LED lights.

The speed of the far end device is higher than the speed of the local terminal device.

Change the speed of the local terminal device to match that of the far end device. If the speed of the far end device is not known, set the local terminal device to the highest speed available.

The far end device is set up for half-duplex or synchronous operation.

The 7400B Data Module cannot communicate with a far end device that is operating half-duplex or synchronous. This problem can be resolved only if the far end device can be reconfigured for full- duplex, asynchronous operation.

The telephone number was dialed incorrectly.

The far end device is not busy, but the PBX has restricted access to the called device.

Check the number of the far end device that you wish to call and try the call again.

This situation can only be resolved by having the PBX readministered to remove the access restriction.
