IP phones connected via an Ethernet service to a softswitch in a service provider network give users the simplicity of automatic adds, moves, and changes, the benefits of a PBX, and line-speed performance for key data applications. Another key application for enterprises is unified communications, the integration of voice mail, e-mail, and personal contact databases. Managing telephone calls can provide an important efficiency boost for all workers if they can pre-identify who is calling and determine if they need to take that particular call or pass the call on to a more appropriate associate. A service POP approach to call center services may make financial sense for enterprises in the future. Networks must become simpler.
Transport networks are increasingly optical, and what are being transported are wavelengths.
Intelligent networking systems that can manipulate and route wavelengths will give carriers greater flexibility in operating their network and greater ease in adding new, popular IP-based applications.
