  1. The ornamental design for an intercommunication unit, substantially as shown and described.

FIG. 1 is a front elevational view of an electronic intercommunication unit showing my new design;

FIG. 2 is a rear elevational view thereof;

FIG. 3 is a left side elevational view thereof;

FIG. 4 is a right side elevational view thereof;

FIG. 5 is a top plan view thereof;

FIG. 6 is a bottom plan view thereof; and

FIG. 7 is a front, top and side perspective view thereof.

The door-phone box of the present design may be used as installed, for example, on a wall at a building entrance or the like in combination with a multifunctional telephone set, so that a manual pressing of the operating button will produce at the telephone set a chime sound of a visitor's calling and a conversation may be made between the door-phone box in the exterior and the telephone set in the interior of a building.
