Assuming that the station 100 is asigned to ports 1 or 2 and that they are in Att class 0. Nite switch can be tested manually by pressing the following with the fone on hook..

Press Feature + 80 + Feature. If this does not work and the above criteria have been met you may have to get a service tech to enable manual nite servive in the operator CLS.. If this works you can program from that fone a manual nite button buy doing .

Fone on hook. Feature + redial + press button to program + #80 + ANS + Feature + Feature. This will give you a nite toggle button.
