Inleiding

In veel omgevingen is het nodig om een toegangsserver te configureren om inkomende oproepen van zowel asynchrone als ISDN-gebruikers te accepteren. Deze gebruikers zouden naadloos met het netwerk kunnen verbinden alsof ze fysiek aanwezig zijn. Vandaar dat deze instelling veel wordt gebruikt om netwerkconnectiviteit te bieden voor reizende en telegebruikers evenals kleine Office-Home Office (SOHO)-sites.

Dit document behandelt hoe u een Cisco 3600 Series router kunt configureren om inkomende asynchrone oproepen op ISDN T1 (PRI of kanaalgekoppelde signalering [CAS]) te accepteren. Deze configuratie bevat alleen het minimale minimum dat vereist is voor de Network Access Server (NAS) om de oproep te accepteren. Afhankelijk van uw behoeften kunnen extra functies aan deze configuratie worden toegevoegd.

Opmerking: Deze configuratie toont niet hoe u Async-dialin via BRI op een 3600 Series router kunt configureren. Raadpleeg voor meer informatie het document Connectiviteit met de modem en een Cisco 3640 BRI.

Voorwaarden

Vereisten

Er zijn geen specifieke vereisten van toepassing op dit document.

Gebruikte componenten

Deze configuratie is ontwikkeld en getest met behulp van de onderstaande software- en hardwareversies.

Cisco 3640 Series router met een 1-poorts gekanaliseerde T1/ISDN-PRI netwerkmodule (NM-1CT1-CSU) en een 24-poorts netwerkmodule met digitale modem (NM-24DM).
De Cisco 3640 router voert Cisco IOS®-softwarerelease 12.1(5)T9 uit.
Eén T1 PRI-circuit.
Eén T1 CAS-circuit.

De informatie in dit document is gebaseerd op apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als u in een levend netwerk werkt, zorg er dan voor dat u de potentiële impact van om het even welke opdracht begrijpt alvorens het te gebruiken.

Verwante producten

Deze configuratie kan worden gebruikt op elke Cisco 3600 Series router met een T1/E1-netwerkmodule en de netwerkmodule voor digitale modem.

Voor een voorbeeldconfiguratie met behulp van de AS5x00 Series routers, raadpleegt u het document Een toegangsserver met PRI’s configureren voor inkomende asynchrone en ISDN-oproepen.

Deze configuratie kan ook worden aangepast voor gebruik met E1- of PRI-poorten. Configureer de E1-controller met de linecodering, vormgeving en andere fysieke eigenschappen die door de Telco zijn geleverd. De PRI D-kanaalconfiguratie (interface-seriële x:15 voor E1s) is gelijk aan de configuratie die hier wordt getoond.

Conventies

Zie de Cisco Technical Tips Convention voor meer informatie over documentconventies.

N.B.: Als u aanvullende informatie wilt vinden over de opdrachten die in dit document worden gebruikt, gebruikt u het IOS-opnamegereedschap (alleen geregistreerde klanten).

Netwerkdiagram

Dit document gebruikt de netwerkinstellingen die in het onderstaande schema zijn weergegeven.

Taken vooraf configureren

Task One

Bepaal het nummer van de sleuf waarin de digitale modems zijn geïnstalleerd. Gebruik de opdracht Show diag EXEC om de sleuf te bepalen waarin de module geïnstalleerd is. Hieronder staat een voorbeelduitvoer van de opdracht show diag EXEC:

acc-3640-6a#show diag
Slot 0:
        CT1 (CSU) Port adapter, 1 port

! -- NM-1CT1-CSU is in slot 0. ! -- The T1 interfaces are addressed as controller t1 slot/port. ! -- In this example, controller t1 0/0. 
        Port adapter is analyzed 
        Port adapter insertion time unknown
        EEPROM contents at hardware discovery:
        Hardware revision 1.1           Board revision D0
        Serial number     22677234      Part number    800-01228-04
        Test history      0x0           RMA number     00-00-00
        EEPROM format version 1
        EEPROM contents (hex):
          0x20: 01 26 01 01 01 5A 06 F2 50 04 CC 04 00 00 00 00
          0x30: 68 00 00 00 00 12 19 00 FF FF FF FF FF FF FF FF

Slot 1:
        Digital Modems Port adapter, 24 ports

! -- Digital modems are in slot 1. Note that there are 24 modems.

        Port adapter is analyzed 
        Port adapter insertion time unknown
        EEPROM contents at hardware discovery:
        Hardware revision 0.3           Board revision UNKNOWN
        Serial number     0             Part number    00-0000-00
        Test history      0x0           RMA number     00-00-00
...
... 

! -- Irrelevant Output omitted

....

Task Two

Bepaal de lijnnummers of het asynchrone interfacebereik dat bij de modemmodule hoort.

Raadpleeg de tabel in het document Hoe asynchrone lijnen worden genummerd in Cisco 3600 Series routers om het lijnbereik te bepalen.

In dit voorbeeld is de netwerkmodule voor digitale modem in sleuf 1 van de Cisco 3640 router. Verwijzend naar het document dat hierboven is genoemd, bepalen we dat het lijnnummerbereik 33 tot 64 is. Aangezien onze modemmodule echter slechts 24 poorten heeft, is het bereik alleen lijnen 33 tot 56 (de resterende 8 lijnen zijn niet gebruikt).

Tip: U kunt de onderstaande formule ook gebruiken om het lijnbereik te vinden:

line number = (<slot> * 32) + <unit> + 1

Vandaar dat bij ons voorbeeld het beginlijnnummer (1 * 32) + 0 +1 = 33 is en het eindlijnnummer 56.

Configuraties

Het volgende is voorbeelden van configuraties voor een Cisco 3640 router die asynchrone oproepen accepteert. Het eerste voorbeeld gebruikt een T1 CAS-circuit, terwijl het tweede monster een T1 PRI-circuit gebruikt. Kies de juiste configuratie, afhankelijk van het T1/E1 circuit dat u hebt.

Verifiëren

Deze sectie verschaft informatie die u kunt gebruiken om te bevestigen dat uw configuratie correct werkt.

Bepaalde opdrachten met show worden ondersteund door de tool Output Interpreter (alleen voor geregistreerde klanten). Hiermee kunt u een analyse van de output van opdrachten met show genereren.

ISDN-status tonen - garandeert dat de router correct met de ISDN-switch communiceert. In de uitvoer, controleer of Layer 1 Status actief is, en of de Layer 2 Status staat = MULTIPLE_FRAME_ESTABLISHED verschijnt. Deze opdracht geeft ook het aantal actieve oproepen weer.
gebruikersnaam voor de beller - toont parameters voor de specifieke gebruiker zoals de toegewezen IP-adres, PPP- en PPP-bundelparameters enzovoort. Als uw versie van Cisco IOS-software deze opdracht niet ondersteunt, gebruikt u de opdracht showgebruiker.
Toon dialer kaart - Toont geconfigureerde dynamische en statische dialerkaarten. Deze opdracht kan worden gebruikt om te zien of er een dynamische dialerkaart is gemaakt. Zonder een dialerkaart kunt u geen pakketten routeren.

Problemen oplossen

Deze sectie bevat informatie waarmee u problemen met de configuratie kunt oplossen.

Bronnen voor probleemoplossing

Gebruik de volgende bronnen voor probleemoplossing zoals vereist:

Problemen oplossen bij inkomende modem - voor analoge gespreksproblemen oplossen.
PRI asynchrone modem - extra informatie over het oplossen van analoge gespreksproblemen.
T1 Problemen oplossen -Gebruik dit stroomschema als u vermoedt dat het T1-circuit niet goed werkt.
Loopback-tests voor T1/56K-lijnen - Om te controleren of de T1-poort op de router correct werkt.

Opdrachten voor troubleshooting

Bepaalde opdrachten worden ondersteund door het gereedschap Uitvoertolk, waarmee u een analyse van de opdrachtoutput kunt bekijken.

Opmerking: Voordat u debug-opdrachten afgeeft, raadpleegt u Belangrijke informatie over debug-opdrachten.

debug dialer - Hiermee geeft u informatie over het foutoptreden van DDR weer over de pakketten die op een dialerinterface worden ontvangen. Deze informatie kan helpen om ervoor te zorgen dat er interessant verkeer is dat de dialerinterface kan gebruiken.
debug ISDN Q931 - Geeft instellingen voor oproepen en verwijdering van de ISDN-netwerkverbinding weer (Layer 3).
debug van modemactiviteit - Hiermee geeft u modemactiviteit op een toegangsserver weer. De uitvoer toont wanneer de modemlijn de status verandert.
debug van modemCCS - Een EXEC-opdracht om problemen bij Call Switching Module (CSM) op routers met interne digitale modems te voorkomen. Met deze opdracht, kunt u de volledige reeks van het overschakelen van inkomende en uitgaande oproepen overtrekken.
debug PPP-onderhandeling - Informatie over het PPP-verkeer en -uitwisselingen tijdens de onderhandelingen over Link Control Protocol (LCP), Verificatie en Network Control Protocol (NCP). Een succesvolle PPP-onderhandeling opent eerst de LCP-staat, dan Verifieert en tenslotte onderhandelt NCP. Tijdens LCP-onderhandelingen worden multilink-parameters vastgesteld, zoals Maximum Get Reconstruction Unit (MRRU).
debug van PPP-verificatie - displays PPP-verificatieprotocolberichten, inclusief CHAP-pakketuitwisselingen en PAP-uitwisselingen (Wachtwoord Verificatie Protocol).
debug van PPP - Hiermee worden protocolfouten en foutstatistieken weergegeven die bij de verbindingsonderhandeling en -handeling in PPP zijn gekoppeld.

Hieronder staan enkele debug-uitgangen voor succesvolle oproepen (met T1 CAS). Let op de bouten en de opmerkingen in de resultaten. Vergelijk de uitvoer die u behaalt met het onderstaande resultaat.
