Customers system was hit by power restoration after last weeks CA power shortage.

Only phone with active ringers was Ext.201, which comes out of the P 1 port.
Set plugged in directly at Port 1 indicates NOTHING.

I cross connected Ext. 211 to where 201 was in suite.
But I do not know how to program Ext. 211 to ring on lines 1 - 4.
Any help would be appreciated.
Thank you.
