DS-1. The term “DS-1” Service is a point to point high-capacity Private Line digital transport service (PLTS) that provides transmission of isochronous serial data at 1.544 MBPS and has the capacity of 24 voice equivalent channels. Because the transmission is digital, the signal is clean and free of cross talk, amplified noise and distortion. DS-1 Service channels are provided between customer-designated premises or between a customer-designated premises and a Carrier’s central office. DS-1 Service may be provisioned on copper, fiber and in some instances, microwave radio. In some high-density cities, DS-1 Service is provisioned on a synchronous optical network (SONET)-based interoffice network that connects key serving wire centers.
