With the migration to Synchronous Digital Hierarchy, which uses the concept of logical rings, for backbone transmission systems, one of the major concerns that has been brought up repeatedly is a method in which to bring sub-rate circuits from one ring to another without having to decompose the entire backbone data stream to its individual circuits. This is critically important since the backbone data rate can be as high as 10 Gigabits per second or greater and may carry several thousand circuits, ranging in data rate from less than 2.4 Kilobits per second to 2.5 Gbps (STM-16). One potential means of providing this capability in cross-connection locations is to implement cross-connection clusters between the rings. This requires detailed planning of the network infrastructure prior to providing the first customer services, in order to avoid having disruptions to that service at a later date. As shown in this paper, the consequences for failing to plan and implement a strategy allowing for expansion and flexibility in the network build-out phases can have a significant impact in terms of revenue and reliability later during routine network operations, especially when service is needed for new customers.
