Yes the soldiers ran or walked suicidally into enemy trenches under machine gun fire.

At the front there was the front line, then there was the support trench and at the back was a reserve trench.

In the same trench, they'd probably just yell down the line or walk. If they were in different trenches, they'd send a runner, someone with a track or some sort of running background to pretty much dodge bullets to get the message to the other trench.
Trench foot
There were differences in the function and importance of trenches. The first one (closest to the enemy) was also called the Front Line or the Fire Line. A 100 yards behind it you had the support trench and again some 100 yards behind, the reserve trench. And then you had the connecting trenches, who were just there so you could get from one trench to the other. There wasn't a real 'hierarchy' anmong trenches: the front line was most important for fighting, but the other two were important for their support facilities, radio and command rooms and as places for soldiers to rest from front line duties.
most combatants at that time NEVER built straight trench's. 1. If a shell struck in to the trench, the shrapnel would go flying everywhere in the trench if it was in a straight line, the "curve" in the trench would deflect the shrapnel. 2. if part of the trench was overrun, resistance could still continue with a zigzag trench. If it was in a straight line, enemy soldiers could just fire there guns in a straight line and kill everyone easily.
A parapet was the front of the front line trench, The top 2-3 feet of the trench consisted of sand bags to absorb bullets and shell fragments. It was in effect a vertical extension of the trench, used to provide cover for the soldiers.
The trench between the front line and the support trench was called a "communication trench." These trenches were crucial for enabling the movement of troops, supplies, and information between the front lines and support positions while minimizing exposure to enemy fire. Communication trenches were often zigzagged to reduce the risk of being hit by enemy artillery.
In the days of trench warfare, they were. In modern times, they are not.
