These side station instruments are similar to the standard intercom sets, with the addition of two lamps associated with the master station lines.

To make a call the micro-telephone is lifted and the appropriate push button is pressed. If the call is to a master station it is indicated there by a lamp and buzzer and is answered by the master operating the relevant key.  If the call is to another side station it is indicated there by a buzzer and is answered by picking up the micro-telephone.

A call from a master station causes the associated line lamp to glow on the side station telephone, even if the latter is engaged, in which case the action of pressing the button of the calling line automatically releases the original connection.  It is not necessary to replace the micro-telephone first.

The red and green push buttons for the two master station lines occupy the left and right-hand end positions of the lowest push button unit, i.e., positions 1 and 5, 6 and 10, and 11 and 15 respectively, on the 5, 10 and 15 line instruments.

N1595A type call and reply sets may also be used as side stations to the N1746 master station telephone, but no provision is made for direct communication between these and the N1732/N1733 intercom side stations.

If it is desired to associate a call and reply telephone with one of the intercom side stations, the former will be of the N1112A type.
