  3. WIRELESS NETWORKS R2 COURSE • SENALIZACION : • INTERCAMBIO DE DATOS ENTRE CENTRALES DE CONMUTACION • CON EL FIN DE ESTABLECER UNA COMUNICACION ENTRE • USUARIOS, O PARA OFRECERLES FACILIDADES O SERVICIOS • ESPECIALES • Jaime Silva PRELIMINARY MAYO 1996

  4. R2 COURSE R2 Course ACCESS AND INTER SWITCHES PROTOCOLS - CAS protocols (R1, R2) - DSS1 protocols (BRI, PRI) - CCS7 with ISUP Jaime Silva PRELIMINARY MAYO 2001

  5. WIRELESS NETWORKS R2 COURSE MFC - LME SENALIZACION ASOCIADA AL CANAL R2 • (PER TRUNK SIGNALLING, PTS) • - SENALES DE LINEA • - SENALES DE REGISTRO • (LINK - BY - LINK, END - TO - END) R1 CCITT-5 - ANALOGICO - DIGITAL CCS # 7 SENALIZACION POR CANAL COMUN • - MENSAJES ESTRUCTURADOS QUE VIAJAN A • TRAVES DE RED DE SENALIZACION • LINK - BY - LINK ( TUP and ISUP ) • Jaime Silva PRELIMINARY MAYO 1996
