Nelle piattaforme router Cisco 2600, 3600 e MC3810 per la segnalazione E&M digitale, alcuni slot temporali T1/E1 possono rimanere bloccati nello stato EM_PARK. Questa condizione è visibile quando si esegue il comando show voice call summary. Questo documento spiega come risolvere il problema.
Questo output mostra che alcuni intervalli di tempo sono nello stato EM_PARK. Una fascia oraria nello stato EM_PARK non viene utilizzata per le chiamate vocali.

Le informazioni fornite in questo documento si basano sulle seguenti versioni software e hardware:
Hardware: Cisco 2600, Cisco 3600, Cisco VG200 e router MC3810
Software: tutto
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.
Nel server T1 CAS, ad esempio, la segnalazione di inizio sink (wink start), quando il PBX viene scollegato, lo slot del tempo laterale del router/gateway rimane nello stato di inattività (EM_ONHOOK) fino a quando una destinazione remota non risponde alla chiamata. Lo stato dell'intervallo di tempo del router cambia in EM_OFFHOOK quando la destinazione remota risponde alla chiamata.
Se la chiamata non si connette, il router/gateway riproduce i toni di riordino in banda al chiamante. Poiché lo stato del canale sul lato del router è ancora EM_ONHOOK, il router non può interrompere il canale. Dopo che il chiamante si è disconnesso, il PBX deve modificare lo stato del canale da offhook a onhook.
In alcuni casi, i PBX non inviano i messaggi onhook, con l'aiuto delle transizioni ABCD. Il router ha a disposizione una soluzione per questa risposta chiamata falsa. Senza una soluzione alternativa falsa, i canali si trovano in uno stato EM_PARK a tempo indeterminato. Per ulteriori informazioni, vedere la sezione Risposta falsa.
Nota: le chiamate possono essere bloccate nello stato EM_PARK su alcuni canali T1 se lo chassis del router del gateway voce non è collegato elettricamente correttamente. Per ulteriori informazioni sulla messa a terra elettrica, consultare la guida all'installazione dell'hardware.
Per ulteriori informazioni sulle convenzioni usate, consultare il documento Cisco sulle convenzioni nei suggerimenti tecnici.
Esistono due possibili motivi principali per cui la fascia oraria è bloccata nello stato EM_PARK:
Il DSP (Digital Signal Processor) è danneggiato e presenta problemi hardware o software.
Lo switch PSTN/PBX invia un segnale di offhook continuo al router e non lo rilascia.
Queste sono le soluzioni al problema:
Se gli slot temporali del sistema sono bloccati nello stato EM_PARK, controllare i DSP. Per controllare i DSP, consultare il documento sulla risoluzione dei problemi del DSP su NM-HDV per i router Cisco serie 2600/3600.
Se i DSP sono attivi, il problema può riguardare lo switch PSTN/PBX o il Cisco IOS® (il router/gateway non avvia la procedura di risposta errata). Per ulteriori informazioni, vedere la sezione Risposta falsa.
Il router/gateway Cisco attende un valore predefinito di 30 secondi (usare i comandi timeout wait-release e timeout call-disconnect per modificare questi valori) dopo aver stabilito che l'intervallo di tempo deve essere impostato dal PBX su onhook durante la riproduzione del tono di riordino.
In caso contrario, il router sposta l'intervallo di tempo nello stato EM_PARK e avvia un altro timer della durata di 10 secondi. Se il PBX non si aggancia ancora dopo la durata di 10 secondi, il router inganna il PBX. Il router invia una risposta falsa di una durata di un secondo e poi si aggancia.
Dopo aver inviato al router il segnale di risposta falso, il router avvia un altro timer di cinque minuti. Se il PBX si aggancia, il timer si arresta e il router passa dallo slot orario allo stato EM_ONHOOK. Altrimenti, dopo cinque minuti invia un altro falso segnale di risposta di una durata di un secondo. Il router ripete questa procedura finché il PBX non si aggancia. Il router forza il PBX a cancellare la chiamata.
Nota: questa transizione di risposta non viene aggiornata ad alcun record contabile poiché la chiamata effettiva viene cancellata. Ma il PBX lo interpreta come una risposta e l'utente probabilmente si paga per la chiamata di durata di un secondo.
Se il DSP associato all'intervallo di tempo nello stato EM_PARK è attivo e integro e il problema persiste, eseguire i comandi debug vpm all e debug vtsp all per verificare se Cisco IOS tenta di inviare la risposta falsa.
Nota: è necessario eseguire i debug per più di cinque minuti.
Nota: nella maggior parte dei casi, se il DSP è guasto, il router non implementa la soluzione alternativa falsa. per ulteriori informazioni, fare riferimento a Risoluzione dei problemi di DSP su NM-HDV per i router Cisco serie 2600/3600.
Questo output di debug mostra come una fascia oraria si blocca in EM_PARK e come funziona la soluzione alternativa delle risposte false.
