Telecom consolidation is driven largely by the need for scale efficiencies, made more urgent as telecom players increasingly compete on price.

A neck injury may cause damage to the phrenic nerve. Symptoms of a phrenic nerve injury may include difficulty breathing. A pacemaker may be surgically implanted into an individual that has difficulty breathing due to phrenic nerve damage. Physical trauma is the most common cause of damage to phrenic nerves.
The phrenic nerve is a nerve that originates in the neck (C3-C5) and passes down between the lung and heart to reach the diaphragm. It is important for breathing, as it passes motor information to the diaphragm and receives sensory information from it.There are two phrenic nerves, a left and a right one.The phrenic nerve originates mainly from the 4th cervical nerve, but also receives contributions from the 5th and 3rd cervical nerves (C3-C5) in humans.here are two phrenic nerves, a left and a right one.
