Examples of DS-1 in a sentence

  • Should the Parties desire to share the cost of Facilities and Trunks, when Facilities larger than DS1 are dedicated to provide traffic under this Agreement, they will separately negotiate the terms for such sharing; otherwise, Carrier shall be fully responsible for costs of such Facilities and Trunks.

  • When such Out of Exchange Traffic is Section 251(b)(5) Traffic, Non-toll VoIP-PSTN Traffic and ISP-Bound Traffic that is exchanged between the End Users of OE-LEC and AT&T-21STATE, the Parties agree to establish a direct End Office trunk group when traffic levels exceed one DS1 (24 DS0s) to or from an AT&T-21STATE End Office.

DS-1. - means a dedicated, high capacity, full duplex channel with a nominal line speed of 1.544 Mbps asynchronous serial data having a line signal format of either alternate mark xxxersion (AMI) or B8ZS and either Superframe (D4) or Extended Superframe formats. DS-1 Service has the equivalent capacity of 24 voice grade services or 24 DS-0 Services. AMI can support 24 56 Kbps channels and (ESF) B8ZS can support 24 64 Kbps channels.
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.
