The design in figure 98 is a suggestion how to build up a generic E1/T1 platform. With
the selection of the appropriate components the same circuitry is also able to handle the
return loss and impedance to ground requirements of ETSI. For more details of this
circuits, please refer to the appropriate application notes listed on the following page.
