Abstract

Det angis en grunnpulsranme som kan benyttes i et synkront nett for grunn- pulsrammer 1 både CEPT- såvel som US-hlerarklet med minst mulig tap av overforlngskapasltec. Den envelope-strukturerte del (SPE) av grunnpulsrainiaen består av 9 linjer (Z) og særdeles av 264 spalter (Sp). Det angis en for slgnailer i CEPT-hierarklet og US-hierarkiet optimal konfigurasjon av hvilke dog hver tillater en overføring av tilstrekkelige signaler av den annen art. Den fortrinnsvise konfigurasjon for CEPT-signaler omfatter 16 hovedblokker (HBla-HBl6a) og to tilleggsblokker (ZBla, ZB2a). Begge tjener til valgfritt belegg med tilleggssignaler, den annen tilleggs- blokk (ZB2a) dessuten også til valgfritt belegg med bruksslgnaler. I 2048 kbit/s CEPT-signaler overfort i den enve- lope-strukturerte del (SPEla) kan det fullstendig innføyes 1544 Icbit/s signaler med noe tap av overføringskapasitet i 34 368 kbit/s signaler i det høyere CEPT-hierarkitrinn som kan følge et felles 139 264 kbit/s hierarkitrinn. Den fortrinnsvise konfigurasjon for US-sig- naler inneholder 21 hovedblokker og 3 eller 4 tilleggsblokker. Denne gmnnpulsranune er egnet for et verdensomspennende dlgitalslgnal-multi- plekshierarkl for et synkront nett.
