Figure 5-22 Two MD2s as 4-wire repeater with simultaneous 4-wire tapping of a TIM (for example
TIM 3V-IE)
In most cases, a repeater is placed at a location where there is also an ST7 station that
includes a TIM. For this reason, the schematics show not only the connection of two MD2s to
form a repeater but also how a TIM is tapped into the 2-wire or 4-wire cable at the location of
the repeater.
