Summary
Modern telecommunications and applications need increased carrier capacity for wide area transport service. In the past, the T1 system has provided this service and will continue to do so for many years. SONET represents second-generation digital carrier technology, which will eventually supplant the T1 technology. Fortunately, SONET is designed to support the T1 technology, which facilitates its placement into the pervasive and ubiquitous infrastructure.
