damage the PME1_21.
To connect E1 cables between the xDDF-21 and the external DDF:

pair of coaxial cables is used for each E1 and can be prepared on site. The cable end connecting to the
xDDF-21 is terminated with a DIN 1.0/2.3 connector. The connector on the other end of the cable
depends on the connector used in the external DDF. For the connection of coaxial cables, see
