One pole with two electric lines / two junctions - how to properly represent this in UN?

Question

We have a potential client and they have basically one straightforward YES/NO question - can you represent our situation in UN? If, yes, we are in, if, no, there is no need for us to migrate to ArcGIS and UN.

I said - yes, it is possible, however with my none experience I cannot say that I know how to do it properly. They have one pole that holds two lines with a junction on each side AND the numbering of junctions that hold the line to pole is each in different numbering. They do not want to change the numbering, obviously because the real life markers on poles are as they are in they own way. Please see my Paint masterpiece attached. I keep my fingers crossed for any suggestions or experience!

@AneteZvaigzneLV  - Like John said, it's standard functionality.
This can be achieved using structural associations. We create a electrical junction object called attachment and place it on the electrical lines. These attachments are then associated to the poles.

In the example below - 
We have a pole that holds up Subtransmission, High Voltage and Low Voltage lines. 
Each of these lines has a attachment (Electric Junction) object created on them. 
There exists a association between the point and Pole.

Now we don't really care what these junctions are called but you have an unique ID for the attachments.
The win for us, is that we can return the pole as a result when we trace the network.
