architecture, carriers can exploit the unique QoS attributes of ATM (and
eventually Internet protocol [IP]) to fashion profitable telephony-grade
broadband voice alternatives. Convergence switching is the means for carriers to Web ProForum Tutorials

The International Engineering Consortium 7/14 marry the reliability and scope of their PSTN investments to the cost and
operational efficiencies of their ATM networks.
As they move toward an integrated voice and data infrastructure, network
carriers will begin to enjoy reduced provisioning cycles and improved and
integrated network management and operations. No longer will carriers require
separate telecommunications management network (TMN) and simple network
management protocol (SNMP) help desks, operations support systems (OSSs),
personnel, and management centers. This simplification will result in decreased
service-delivery costs and, therefore, increased profitability. Convergence
switching also enables carriers to offer new, innovative services that protect their
customer base while expanding geographic and vertical market penetration.
Carriers will benefit from leveraging their existing data infrastructure to fashion
telephony-grade, cost-effective, profitable broadband voice services through the
use of a converged switching architecture. Self-Test
1. Convergence technologies completely interoperate with the existing PSTN
2. Analysts predict that data will consume __________ percent of the world’s
bandwidth by 2003.
3. Which of the following will carriers not do as a result of shrinking telephony
revenues and profitability?
a. increase the number of overlay network platforms
b. cap investment in traditional circuit switches
c. migrate to a converged switching infrastructure
d. provide more enhanced services
