2 R2 COURSE Jaime Silva MAYO 2001 PRELIMINARY Based on Q.400 Series ITU-T Recommendations R2 Course ACCESS AND INTER SWITCHES PROTOCOLS R2 OVERVIEW LINE SIGNALLING REGISTER SIGNALLING SIGNALLING PROCEDURES

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

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

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

6 R2 COURSE Jaime Silva MAYO 1996 WIRELESS NETWORKS SENALIZACION R2 (MFC-LME ) CON SISTEMA DIGITAL ( PCM ) DE MULTIPLEX ENTRE CENTRALES LAS SENALES DE REGISTRO VAN POR EL MISMO CANAL TELEFONICO POR DONDE HABLAN LOS USUARIOS CUANDO QUEDE ESTABLECIDA LA COMUNICACION.
