4 What is the likely impact of moving a conventional company architecture to a comple

network?

Local analog phone service can be completely outsourced to cost-effective provid

The Ethernet VLAN structure is less complex.

A shared infrastructure is created resulting in a single network to manage.

QoS issues are greatly reduced.

There is less bandwidth competition between voice and video streams.
