A1.5 LSD Interface
The LSD interface is for the transmission of low speed data.
This interface in this variant is not in use.
A1.6 HSD Interface
This interface can be used as transparent data interface (High Speed Data).
This interface in this variant is not in use.
In addition on this socket the outputs of the three signalling relays are availa-
ble.
