Technical Glitch

I was reading an old novel ... The plot was based on the background of 80's or before ...
It was a crime thriller , and the turning point of the whole thriller was a "Technical error" !!

You all probably remember that , before Mobile Phone , there used to be Land Telephones , through which people used to communicate with each other ... As the Telecommunication Technology was in it's primitive stage , many "Technical Errors" used to interrupt the service ...

One of such error was "Cross Connection"...

Well... As I never had any personal experience of this , so I can only try to understand and describe it as it was narrated in the Novel...

During a Phone Call between Two Caller through Land Telephone , sometimes some Third Party accidentally get access into the ongoing conversation ... Then it called as "Cross Connection" ...

As I am not a technical person , so I can't really say why this used to be happened !!

The closest thing I can relate to this , is "Wrong Number" !!!

As many times we get calles from unknown people and find out that it's nothing but a "Wrong Number"...
Though , many times , those "Wrong Number" calls look suspicious ... Like it was more of some kind of "Human Error (Preeplanned)" rather than a "Technical Error" !!

But anyway...
This idea of "Cross Connection" seems very interesting and dramatic to me (Though some may consider it as a serious Privacy issue) !!

Just imagine !!!
You and your Love , in the middle of an intimate passionate conversation over the phone , and suddenly you guys hear the sound of a deep breathing from an unknown unexpected source !!!!!
