Analogue DID trunks, are as basic a CO trunk you can have as a 2-wire ckt. Since they are one-way service, one end is called DPO (Dial Pulse Originate), and the other end is called DPT (Dial Pulse Terminate).They use reverse battery loop signaling with start signal option types of Wink Delay, or Immediate. They are NOT Ground-start or Loop-start, and they don't have any dialtone! When using a 4-wire voice path, separate transmit and receive, the circuit expands to another signaling pair for type one E/M, although you can have a 2-wire voice with E/M also in the simplest version.
When you move the DID ckt to DS1, the channel is equivalent to 6-wire E/M, that is one pair each for transmit audio, receive audio, and signaling in both directions.
Now depending what you are ordering on the DS1 will determine how you will configure the channels. Is the DS1 being terminated on a 100D module in slot 5 in the Magix or some other arrangement? If they are going to be only DID trunks, and you are using Wink-start signaling with a four digit feed, then the configuration in your printout is correct. What about your DS1 parameters? Who is the provider, and what kind of CO switch are they using?
