Switch Module.

entered your Dial numbers correctly.

problem.

Switch Module ECS digital port may be offline or
disconnected. Or you are connected to an incompatible
communication device. The ISDN link has too many errors to
maintain a valid connection. Try changing your ISDN Connect
Rate from Auto to 56k.
