E&M Interface Types

There are five different types of the E&M interface and the MVP210/410/810 models support them all; but Type IV is largely unused and will not be detailed in this section. The figures below will show the pin assignments for the MVP RJ48 connector when used in the E&M jacks on the back of the unit as well as how the signals are used for types one, two, three and five. Common ground between the MultiVOIP and PBX is required for all E&M Types except Type II. Two and four wire audio is available for all E&M Types and is shown in figure 4-9 below.
