4 2. Predmet špecifikácie Tento dokument je technickou špecifikáciou účastníckych prípojok dátových sietí a slúži pre záujemcov o zriadenie dátových služieb. Bližšie informácie v prípade potreby poskytneme prípadným záujemcom priamo v našom obchodnom zastúpení : SWAN, a.s. Borská 6, Bratislava info@swan.sk Akékoľvek zmeny, ktoré budú mať vplyv na činnosť KZ budú zverejnené a dostupné priamo v našom obchodnom zastúpení. 3. Koncový bod siete Koncový bod siete kde sa pripája KZ tvorí účastnícka zásuvka ukončená podľa nasledujúcej fyzickej špecifikácie pre jednotlivé typy rozhraní. Používané typu rozhraní pre jednotlivé rýchlosti: Rozhranie Prenosové rýchlosti X.21 do 2 048kbit/s G.703 od 2 048kbit/s do kbit/s G.957 n x 155Mbit/s (STM-1, STM-4) IEEE Mbit/s, 100Mbit/s, 1000Mbit/s Technická špecifikácia účastníckych rozhraní dátových sietí (v1.1) 4/4
5 4. Fyzické parametre rozhrania 4.1 Rozhranie X.21 Fyzické prevedenie rozhrania tvorí rozoberateľný spoj s 15-vodičovým konektorom podľa ISO 4903 s nasledovným priradením signálov: Okruh podľa ITU-T Popis okruhu Smer signálu Vývod A Vývod B G Ground DTE - DCE 8 - T Transmitted data DTE - DCE 2 9 R Received data DTE - DCE 4 11 C Control DTE - DCE 3 10 I Indication DTE - DCE 5 12 S Signal Element Timing DTE - DCE 6 13 B Byte Timing DTE - DCE Rozhranie G.703 Rozhranie je určené k pripájaniu zariadení vyhovujúcich odporúčaniu ITU-T G.703 pre rýchlosti n x 64 kbit/s. Fyzické prevedenie pre balancovanú termináciu rozhrania tvorí rozoberateľný spoj s 8-vodičovým konektorom podľa odporúčania CCITT G.703 s nasledovným priradením signálov: Okruh podľa ITU-T Popis okruhu Smer signálu Vodič A Vodič B T Transmitted data DTE - DCE 1 2 R Received data DTE - DCE 4 5 S1 Transmit ground 3 - S2 Recieve ground 6 - Pre nebalancovanú termináciu sa používa dvojica BNC konektorov a kábel s impedanciou 75ohm.
