Configurazione e risoluzione dei problemi di segnalazione T1 CAS

Introduzione

Questo documento spiega le configurazioni necessarie per implementare il sistema di segnalazione associato al canale T1 (CAS).

Prerequisiti

Requisiti

Prima di provare questa configurazione, accertarsi di soddisfare i seguenti requisiti:

Questo documento si basa sul funzionamento di Digital T1 CAS (Robbed Bit Signaling) sui gateway IOS. Leggere questo documento per comprendere i vari tipi di metodi di segnalazione CAS. Questo documento funge anche da guida per la configurazione dei diversi tipi di segnalazione CAS.

Prima di implementare la segnalazione E1 R2 in un router Cisco AS5300, verificare che la versione del software Cisco IOS® in uso sia compatibile con Cisco VCWare nel modulo E1. Se le versioni non sono compatibili, i moduli DSP (Digital Signal Processor) nella scheda voce non verranno caricati e non verrà eseguita l'elaborazione del segnale vocale. Per verificare la compatibilità delle versioni, consultare la matrice di compatibilità di Cisco VCWare per Cisco AS5300.

In genere, se la versione di Cisco VCWare non è compatibile con il software Cisco IOS, è possibile verificare questa condizione immettendo il comando show vfc slot_number interface come mostrato di seguito:

5300#show vfc 1 interface
Rx: in ptr 18, outptr 0
Tx: in ptr 14  outptr  14
0 in hw queue, 0 queue head , 0 queue tail
Hardware is VFC out-of-band channel
Interface : state RESET DSP instance (0x61048284)
dsp_number 0, Channel ID 0
TX outstanding 0, max TX outstanding 0
Received 18 packets, 1087 bytes, 0 giant packets
0 drops, 0 no buffers, 0 input errors
121 bytes output, 14 frames output
0 bounce errors 0

DSP module 1 is not installed
DSP module 2 is not installed
DSP module 3 is not installed
DSP module 4 is not installed
DSP module 5 is not installed

Nell'output precedente, le istruzioni "DSP module number is not installed" (Il numero del modulo DSP non è installato) mostrano che le versioni non sono compatibili per quel numero di modulo. Di seguito è riportato un esempio di moduli DSP in cui è caricata la versione corretta di Cisco VCWare:

5300#show vfc 1 interface
Rx: in ptr 24, outptr 0
TX: in ptr 15  outptr  15
0 in hw queue, 0 queue head , 0 queue tail

TX outstanding 0, max TX outstanding 8
Received 0 packets, 0 bytes, 0 giant packets
0 drops, 0 no buffers, 0 input errors
0 bytes output,  0 frames output
0 bounce errors 0

Per controllare la versione di Cisco VCWare installata, immettere il comando show vfc slot_number version vcware, come mostrato di seguito:

5300#show vfc 1 version vcware
Voice Feature Card in Slot 1:
VCware Version : 4.10
ROM Monitor Version : 1.2
DSPware Version :
Technology :  C542

Nota: verificare che la versione della tecnologia Cisco VCWare (c549 o c542) corrisponda alla tecnologia DSP Voice Feature Card installata (DSPM-542: supporto vocale a densità singola, o DSPM-549: supporto vocale ad alta densità).

Convenzioni

Per ulteriori informazioni sulle convenzioni usate, consultare il documento Cisco sulle convenzioni nei suggerimenti tecnici.

Configurazione

In questa sezione vengono presentate le informazioni necessarie per configurare le funzionalità descritte più avanti nel documento.

Nota: per ulteriori informazioni sui comandi menzionati in questo documento, usare lo strumento di ricerca dei comandi (solo utenti registrati).

Configurazioni

Per eseguire la segnalazione CAS sui router Cisco serie 2600/3600, è necessario un High Density Voice Network Module (NM-HDV).

Il comando ds0-group (o cas-group, a seconda della versione di Cisco IOS) deve essere definito sui controller T1 (Cisco AS5xxx e router 2600/3600).

Per configurare CAS, utilizzare la procedura seguente:

1. Impostare il controller T1 collegato al PBX (Automatic Branch Exchange) o allo switch. Verificare che il frame e il codice di linea di T1 siano impostati correttamente.

   • Frame T1: FSE o SF

   • Codifica di riga T1: B8ZS o AMI

   • Origine orologio T1: interno o linea

   Nota: tenere presente che i diversi PBX hanno requisiti diversi sull'origine dell'orologio.

2. Utilizzare questa sequenza di comandi per definire la segnalazione della linea sulle piattaforme AS5xxx:

   5300(config)#controller T1 0
   
   5300(config-controller)#
   ds0-group 1 timeslots 1-24 type ?
   
   e&m-fgb              E & M Type II FGB
   e&m-fgd              E & M Type II FGD
   e&m-immediate-start  E & M Immediate Start
   fgd-eana             FGD Exchange Access North American
   fgd-os               FGD Operator Services
   fxs-ground-start     FXS Ground Start
   fxs-loop-start       FXS Loop Start
   none                 Null Signaling for External Call Control
   r1-itu               R1 ITU
   sas-ground-start     SAS Ground Start
   sas-loop-start       SAS Loop Start
   <cr>

   Nota: se si desidera raccogliere informazioni DNIS (Dialed Number Identification Service) su un controller T1, è necessario configurarle manualmente sul server di accesso. Per raccogliere il DNIS (DTMF) a doppia frequenza per E&M-fgb in una configurazione T1 del controller, usare il comando ds0-group 0 timeslot 1-24 type e&m-fgb dtmf dnis. Per raccogliere DNIS multifrequenza (MF) per E&M-fgb, utilizzare il comando ds0-group 0 timeslot 1-24 type e&m-fgb mf dnis.

3. Utilizzare questa sequenza di comandi per definire la segnalazione sulla linea sulle piattaforme Cisco 2600/3600:

   3600(config)#controller T1 0
   3600(config-controller)# 
   ds0-group 1 timeslots 1-24 type ? 
   
   e&m-delay-dial       E & M Delay Dial
   e&m-fgd 			 E & M Type II FGD
   e&m-immediate-start  E & M Immediate Start
   e&m-wink-start       E & M Wink Start
   ext-sig              External Signaling
   fgd-eana             FGD-EANA BOC side
   fxo-ground-start     FXO Ground Start
   fxo-loop-start       FXO Loop Start
   fxs-ground-start     FXS Ground Start
   fxs-loop-start       FXS Loop Start
   none                 Null Signaling for External Call Control
   <cr>

   Con il software Cisco IOS versione 11.3, la sequenza di comandi è la seguente.

   peggy(config)#controller T1 0
   
   peggy(config-controller)#cas-group 1 timeslot 1-15 type ?
   
   ...

   Nota: se si esegue l'aggiornamento dal software Cisco IOS versione 11.3 alla versione 12.0, il nuovo comando sostituirà automaticamente quello precedente.

Nel documento vengono usate queste configurazioni:

• Cisco 5300 configurato per E&M-FGD DTMF DNIS

• Cisco 5300 configurato per E&M-FGB

• Cisco 3600 configurato per E&M FGB (wink-start)

Verifica

Attualmente non è disponibile una procedura di verifica per questa configurazione.

Risoluzione dei problemi

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

Procedura di risoluzione dei problemi

Seguire queste istruzioni per risolvere i problemi relativi alla configurazione. Per ulteriori informazioni sulla risoluzione dei problemi, consultare il documento sulla personalizzazione di E1 R2 con il comando cas-custom.

1. Verificare che il controller T1 0 sia attivo. Se il cavo è spento, controllare i frame, la codifica della linea, l'origine dell'orologio, gli allarmi, sostituire il cavo, riposizionare la scheda e così via.

2. Se si utilizza un Cisco AS5300, verificare che i DSP siano installati correttamente con il comando show vfc slot number interface.

3. Per i trunk FGD configurare il Direct Inward Dial (DID) sul peer POTS (Plain Old Telephone Service), in modo che le cifre ricevute vengano utilizzate per scegliere un peer in uscita.

   Nota: su Cisco AS5300 è necessario configurare l'opzione "dnis" per richiedere DNIS.

4. Attivare alcuni dei comandi debug mostrati nella sezione seguente e studiare gli output

5. Verificare la comunicazione tra il router e il PBX o lo switch.

   • La linea è bloccata?

   • Il router riceve/invia cifre?

   • Scopri da che parte sta cancellando la chiamata.

   • Se possibile, utilizzare le versioni software Cisco IOS più recenti disponibili sul sito Cisco.com.

Determinazione della segnalazione su un router Cisco AS5xxx

Può essere difficile determinare il tipo di segnalazione di cui si dispone guardando i debug di un router. Tuttavia, è possibile fare una buona ipotesi su quale dovrebbe essere il segnale. Il comando debug riportato di seguito è abbastanza affidabile (soprattutto quando tutti i canali sono inattivi) nel determinare il tipo di segnalazione. È consigliabile verificare innanzitutto la segnalazione in questi debug, in quanto possono rilevare gli errori di provisioning più comuni e non così ovvi. Come al solito, prestare attenzione quando si attivano i debug sul router. È consigliabile attivare il debug solo se si ha familiarità con le relative funzionalità. Tenere presente che non tutti i debug sono disponibili per ogni piattaforma NAS (Network Access Server).

Comandi per la risoluzione dei problemi

Lo strumento Output Interpreter (solo utenti registrati) (OIT) supporta alcuni comandi show. Usare l'OIT per visualizzare un'analisi dell'output del comando show.

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

• debug serial interface - Visualizza informazioni su un errore di connessione seriale.

• show controller t1: visualizza lo stato del controller specifico per l'hardware del controller.

• debug cas: per la segnalazione della linea sulle piattaforme Cisco AS5xxx.

• debug vpm signal: per la segnalazione di linea su piattaforme Cisco 26xx/36xx.

• debug vtsp all: abilita l'output di tutti i messaggi (cifre) scambiati tra il PBX e il router.
