Figure 22 - 4-Wire E&M Type 1 (Rev A Main Board)

Figure 20 shows the GTI telephone interface configured per Table 2 for 4-Wire E&M, Microwave. Eight wires are needed to connect to the telephone company side, and 1000 ohms must be installed in series with the E-Lead. The interface interprets the absence of E-Lead current as an idle condition. The interface provides an opened-loop M-Lead for an idle condition and a closed-loop for a busy condition.

Figure 22 shows the GTI telephone interface configured per Table 2 for 4-Wire E&M, Type I. Six wires are needed to connect to the telephone company side, and 1000 ohms must be installed in series with the E-Lead. The interface interprets the absence of E-Lead current as an idle condition. The interface provides an open M-Lead for an idle condition and applies -48 V for a busy condition.
