(b) The block and schematic diagrams of patching modules included the

designations for REC, SEND, DROP, LINE, EQUIP, and MON to correspond to the

jack appearances of circuits and leads on the module front panels.

drawings, the tip and ring leads on the

line side are identified simply by

T and R, and on the equipment side as T1

and R1.

This facilitates lead

identification at the patching module

terminal boards, as shown in figure

(d) Figures 1-6 and 1-5 show monitor jacks on the line side only. This

is also reflected in the front panel layouts of figure 1-4, where each jack

set column contains only a single monitor jack. This arrangement, with the

monitor jack on the line side, is the minimum requirement stated by MIL-STD

188-310A. In some of the arrangements there is an additional monitor jack

on the equipment side to permit monitoring of the signal to the equipment.
