Appendix B : Ethernet Cabling Guidelines

Introduction

The 3300 ICP system transmits voice communications over a data network using Voice over Internet
Protocol (VoIP). Electrical interference in the environment can reduce the quality of the voice and data
signals that are transmitted over Ethernet cable. Desktop computers, printers, servers, lighting, and other
office devices place a high demand on the electrical infrastructure and increase the risk of electrical inter-
ference. You can minimize electrical interference and improve network efficiency by following the cabling
guidelines detailed in this appendix.
: Special testing equipment is available from Mitel Product Support. This equipment can verify
