Metro area telecommunications providers need to deliver a mix of inherently incompatible services to enterprise customers, who expect compatibility and consistency across all their locations. Under pressure to provide bundled services at lowest possible costs, with fast response to service requests, service providers need to reach all of their customer locations in the most cost-effective way. They need to evaluate the cost of running separate circuits to each location to support disparate services, and have to consider the bottom-line justification for extending services into areas where only one prospect may be lined up. Service providers also need to determine whether equipment. | Overview APPLICATION NOTE Metro area telecommunications providers need to deliver a mix of inherently incompatible services to enterprise customers who expect compatibility and consistency across all their locations. Under pressure to provide bundled services at lowest possible costs with fast response to service requests service providers need to reach all of their customer locations in the most cost-effective way. They need to evaluate the cost of running separate circuits to each location to support disparate services and have to consider the bottom-line justification for extending services into areas where only one prospect may be lined up. Service providers also need to determine whether equipment costs can be justified if that first sale doesn t lead to more business from that location. Historically service providers have had three sub-optimal responses to these challenges Run redundant network links owned or leased circuits to customer locations to provide the mix of packet and TDM time division multiplex services they require. Use dumb gateway devices to aggregate services for transport but sacrifice the ability to monitor performance all the way to the network edge and deliver on service level agreements SLAs . Deploy high-powered SONET add-drop multiplexers ADMs or Layer 2 packet switches to build out the metro network but only for service areas that cost-justify the expenditure. The first option is cumbersome and costly. The second approach is inexpensive but inadäquate to meet customer expectations for network performance. The third strategy is suitable for high-density serving areas but doesn t address new markets or small branch locations of the best enterprise customers. Other options include traditional time division multiplex TDM services such as voice trunks from private branch exchange PBX systems and leased-line data services which still represent substantial revenue. Providers need to determine the best way to win business from customers who .
