Linguaggio senza pregiudizi

La documentazione per questo prodotto è stata redatta cercando di utilizzare un linguaggio senza pregiudizi. Ai fini di questa documentazione, per linguaggio senza di pregiudizi si intende un linguaggio che non implica discriminazioni basate su età, disabilità, genere, identità razziale, identità etnica, orientamento sessuale, status socioeconomico e intersezionalità. Le eventuali eccezioni possono dipendere dal linguaggio codificato nelle interfacce utente del software del prodotto, dal linguaggio utilizzato nella documentazione RFP o dal linguaggio utilizzato in prodotti di terze parti a cui si fa riferimento.

Informazioni su questa traduzione

Cisco ha tradotto questo documento utilizzando una combinazione di tecnologie automatiche e umane per offrire ai nostri utenti in tutto il mondo contenuti di supporto nella propria lingua. Si noti che anche la migliore traduzione automatica non sarà mai accurata come quella fornita da un traduttore professionista. Cisco Systems, Inc. non si assume alcuna responsabilità per l’accuratezza di queste traduzioni e consiglia di consultare sempre il documento originale in inglese (disponibile al link fornito).

Introduzione

Questa configurazione dispone di un Cisco AS5400 con un PRI (Primary Rate Interface) e supporto per 23 chiamate modem o ISDN, a seconda della chiamata in uscita o in entrata dell'host. È configurato con quattro PRI per consentire connessioni in uscita Async e ISDN. Sono state configurate mappe dialer statiche sul lato della composizione per ciascuna connessione ISDN o Async. Stiamo utilizzando route IP statiche a entrambe le estremità della connessione per evitare il sovraccarico non necessario di un protocollo di routing dinamico. Per aggiungere una località remota è necessario aggiungere una mappa dialer, un nome utente e una route statica per la nuova destinazione sul lato della composizione. Tutti i nodi remoti dispongono di indirizzi IP fissi.

Nota: questo documento non copre le chiamate modem e ISDN in arrivo sui router serie AS5350 o AS5400. Per ulteriori informazioni, consultare il documento sulla configurazione di un AS5350/AS5400 per le chiamate asincrone e ISDN in arrivo.

Prerequisiti

Requisiti

Prima di provare la configurazione, verificare che siano soddisfatti i seguenti requisiti:

  • Accertarsi che i circuiti PRI ISDN siano forniti da Telco per la sincronizzazione telefonica e asincrona.

Componenti usati

Le informazioni fornite in questo documento si basano sulle seguenti versioni software e hardware:

  • AS5400 con software Cisco IOS® versione 12.2(6)

  • Un PRI T1 attivo

  • Modem Nextport con portware 0.6.108.0

Poiché questa configurazione è valida solo per le connessioni analogiche e ISDN di base, è sufficiente una qualsiasi versione del software Cisco IOS supportata sui modelli AS5350 e AS5400. Per eseguire funzionalità aggiuntive, fare riferimento allo strumento Software Advisor per selezionare la versione e il set di funzionalità di IOS appropriate per le proprie esigenze.

Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi.

Prodotti correlati

Questa configurazione può essere applicata anche al server di accesso AS5350 o AS5400.

Questa configurazione può essere modificata per l'uso con le porte PRI E1. Configurare il controller E1 con la codifica della linea, il framing e altre caratteristiche fisiche fornite dalla Telco. La configurazione del canale D (interfaccia Serial x:15 per E1) è simile a quella mostrata di seguito.

Questa configurazione è molto simile alla configurazione di AS5200 o AS5300 per l'accesso dial-out. Fare riferimento al documento AS5300 Dialing out with ISDN/Async (Outbound DDR). L'unica modifica importante tra le due è il comando dial-tdm-clock priority number t1_slot/port usato per assegnare la priorità dell'orologio T1 negli AS5350 o AS5400.

È inoltre possibile modificare questa configurazione per supportare sia le chiamate in ingresso che quelle in uscita. Per ulteriori informazioni, consultare il documento Configurazione di chiamate in ingresso e in uscita sugli stessi circuiti PRI T1/E1

Convenzioni

Verifica

Le informazioni contenute in questa sezione permettono di verificare che la configurazione funzioni correttamente.

Alcuni comandi show sono supportati dallo strumento Output Interpreter (solo utenti registrati); lo strumento permette di visualizzare un'analisi dell'output del comando show.

  • show isdn status: lo stato deve essere: 

    layer 1 = active 
layer 2 = MULTIPLE_FRAMES_ESTABLISHED

    Se il layer 1 non è attivo, la scheda o la porta di cablaggio potrebbe essere guasta o non collegata. Se il layer 2 è in uno stato "TEI_ASSIGNMENT", il router non sta parlando con lo switch. Fare riferimento al documento T1 PRI Troubleshooting per ulteriori informazioni.

  • show isdn service - Per controllare lo stato dei canali B. Per ogni chiamata deve essere presente un canale occupato.

  • show caller: visualizza i parametri per l'utente specifico, ad esempio l'indirizzo IP assegnato, i parametri PPP (Point to Point Protocol) e PPP bundle e così via. Se la versione in uso del software Cisco IOS non supporta questo comando, usare il comando show user.

Risoluzione dei problemi

Le informazioni contenute in questa sezione permettono di risolvere i problemi relativi alla configurazione.

Comandi per la risoluzione dei problemi

Alcuni comandi show sono supportati dallo strumento Output Interpreter (solo utenti registrati); lo strumento permette di visualizzare un'analisi dell'output del comando show.

Nota: prima di usare i comandi di debug, consultare le informazioni importanti sui comandi di debug.

Configurare i timestamp nella configurazione globale nel modo seguente: 

service timestamps debug datetime msec 
service timestamps log datetime msec

Utilizzare i seguenti comandi per la risoluzione dei problemi:

  • debug dialer: quando il routing DDR (Dial-on-Demand Routing) è abilitato sull'interfaccia, questo comando visualizza informazioni sulla causa di qualsiasi chiamata (detta causa di composizione).

  • debug isdn q931: per controllare le connessioni ISDN quando vengono avviate le chiamate in uscita.

  • debug ppp negotiation: per verificare se un client sta passando una negoziazione PPP. Un numero elevato di negoziazioni PPP simultanee può sovraccaricare la CPU del router.

  • debug ppp authentication: per verificare se un client sta passando l'autenticazione.

  • debug ppp error: consente di visualizzare gli errori di protocollo e le statistiche degli errori associate alla negoziazione e al funzionamento della connessione PPP.

Per la risoluzione dei problemi relativi al modem, utilizzare i seguenti comandi:

  • debug modem: per verificare se il router riceve i segnali corretti dal modem.

  • debug modem csm: per abilitare la modalità di debug del modulo CSM (Call Switching Module) di gestione del modem.

Per ulteriori informazioni sui comandi Nextport, consultare il documento sulla gestione dei servizi delle porte su Cisco AS5400 Universal Gateway.
