T1/E1 및 디지털 모뎀 네트워크 모듈로 Cisco 3600 라우터 구성
목차
소개
많은 환경에서 비동기 및 ISDN 사용자 모두로부터 걸려오는 전화를 수락하려면 액세스 서버를 구성해야 합니다. 이러한 사용자는 마치 물리적으로 존재하는 것처럼 네트워크에 원활하게 연결할 수 있습니다. 따라서 이 설정은 주로 이동 및 재택 근무 사용자와 SOHO(Small Office-Home Office) 사이트를 위한 네트워크 연결을 제공하는 데 사용됩니다.
이 문서에서는 ISDN T1(PRI 또는 CAS(Channel Associated Signaling) 회로에서 수신 비동기 통화를 수락하도록 Cisco 3600 Series 라우터를 구성하는 방법에 대해 설명합니다. 이 컨피그레이션에는 NAS(Network Access Server)가 통화를 수락하는 데 필요한 최소 베어(bare minimum)만 포함됩니다. 필요에 따라 이 구성에 추가 기능을 추가할 수 있습니다.
참고: 이 컨피그레이션에는 3600 Series 라우터에서 BRI를 통한 비동기 다이얼인을 구성하는 방법이 표시되지 않습니다. 자세한 내용은 Cisco 3640 BRI를 사용한 모뎀 연결 구성 문서를 참조하십시오.
사전 요구 사항
요구 사항
이 문서에 대한 특정 요건이 없습니다.
사용되는 구성 요소
이 구성은 아래의 소프트웨어 및 하드웨어 버전을 사용하여 개발 및 테스트되었습니다.
-
1포트 Channelized T1/ISDN-PRI Network Module(NM-1CT1-CSU) 및 24포트 NM-24DM(Digital Modem Network Module)이 포함된 Cisco 3640 Series 라우터
-
Cisco 3640 라우터는 Cisco IOS® Software 릴리스 12.1(5)T9를 실행하고 있습니다.
-
T1 PRI 회로 1개
-
T1 CAS 회로 1개
이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다. 이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다. 라이브 네트워크에서 작업하는 경우, 사용하기 전에 모든 명령의 잠재적인 영향을 이해해야 합니다.
관련 제품
이 컨피그레이션은 T1/E1 네트워크 모듈 및 디지털 모뎀 네트워크 모듈이 있는 모든 Cisco 3600 Series 라우터에서 사용할 수 있습니다.
AS5x00 Series 라우터와 관련된 샘플 컨피그레이션은 수신 비동기 및 ISDN 통화에 대해 PRI를 사용하여 액세스 서버 구성 문서를 참조하십시오.
이 컨피그레이션은 E1 또는 PRI 포트와 함께 사용하도록 수정할 수도 있습니다. Telco에서 제공하는 라인 인코딩, 프레이밍 및 기타 물리적 특성으로 E1 컨트롤러를 구성합니다. PRI D-channel 컨피그레이션(E1의 경우 Serial x:15 인터페이스)은 여기에 표시된 것과 유사합니다.
표기 규칙

구성
이 섹션에는 이 문서에서 설명하는 기능을 구성하기 위한 정보가 표시됩니다.
참고: 이 문서에 사용된 명령에 대한 추가 정보를 찾으려면 IOS 명령 조회 도구(등록된 고객만 해당)를 사용합니다.
네트워크 다이어그램
이 문서에서는 아래 다이어그램에 표시된 네트워크 설정을 사용합니다.
사전 구성 작업
작업 1
디지털 모뎀이 설치된 슬롯 번호를 확인합니다. show diag EXEC 명령을 사용하여 모듈이 설치된 슬롯을 확인합니다. 다음은 show diag EXEC 명령의 샘플 출력입니다.
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

Serial number 22677234 Part number 800-01228-04

작업 2
모뎀 모듈과 연결된 회선 번호 또는 비동기 인터페이스 범위를 확인합니다.
행 범위를 결정하려면 Cisco 3600 Series Routers에서 How Async Lines are Numbered in Cisco 3600 Series Routers(비동기 회선 번호 매기기 방법) 문서에서 찾은 표를 참조하십시오.
이 예에서는 Digital Modem Network Module이 Cisco 3640 라우터의 슬롯 1에 있습니다. 위에서 언급한 문서를 참조하여 라인 번호 범위는 33~64입니다. 그러나 모뎀 모듈에 24개의 포트만 있으므로 범위는 33줄부터 56줄까지입니다(나머지 8개의 라인은 사용되지 않음).
팁: 아래 표시된 공식을 사용하여 라인 범위를 찾을 수도 있습니다.
line number = (<slot> * 32) + <unit> + 1
따라서 예를 들어, 시작 라인 번호는 (1 * 32) + 0 +1 = 33이고 최종 라인 번호는 56입니다.
구성
다음은 비동기 호출을 수락하는 Cisco 3640 라우터의 샘플 컨피그레이션입니다. 첫 번째 예에서는 T1 CAS 회로를 사용하는 반면 두 번째 샘플은 T1 PRI 회로를 사용합니다. 보유한 T1/E1 회로에 따라 적절한 컨피그레이션을 선택합니다.
