We use these networks to connect us with our coworkers and to collaborate with customers in doing the business of the firm. This chapter reviews the dangers that threaten our telecommunications networks and the attributes unique to these networks that require special processes to restore them after a disaster.

While the need for two distinct networks is slowly changing with the increasing use of VoIP (Voice-over-Internet Protocol) for sending voice communications over the Internet, many organizations will have to maintain both for the foreseeable future. Fortunately for our planning purposes, both types of networks have very similar issues that affect disaster recovery
