2.2 Circuit Switched Services - AT&T

Contract # GS00T01AHD0002Proposal to add Federal Telecommunications Service – Long Distance (FTS-LD)2.2.1.2 Switched Voice Service Transport Requirements(C.2.2.1.2)The SVSs are served by a common set of network elements, with transport betweenthese elements provided on AT&T’s WIN. AT&T’s WIN transmits ___________ofall domestic traffic using high-speed fiber-optic technology and is ___________digital for all traffic. AT&T has more high-capacity fiber to more places than anyother carrier. The bottom line for the end user is that ___________ of all domesticcalls are completed on the first attempt.2.2.1.2.1 Basic Service Description (C.2.2.1.2.1)The FTS-LD SVS will support connections for voice or analog data up to at least 9.6kbps using an ITU-TSS V.32 modem and 28.8 kbps using and ITU-TSS V.34modem. It will allow voice calls initiated from on-net locations and off-net locations,after verification of authorization codes, to be connected to all on-net and off-netlocations by direct station-to-station dialing.SVS will comply with ANSI T1.101 and all applicable Bellcore and ANSI standards,primarily Bellcore’s BOC Notes on the LEC Networks, and ANSI ISDN and SS7standards.The SVS, like Circuit Switched Data Service (CSDS), and ___________are servedby a common set of network elements, with transport between these elementsprovided on the AT&T WIN. These are as follows:+ Switching ⎯ Performs switching and call management for the AT&Tswitched network services+ Signaling ⎯ Provides SS7Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this proposal.q:\mcghee\vol_1sec2d_r.docI-2-80
