Cisco Router E1/T1 Configuration

Cisco Router E1 Configuration

*. E1회선 개통 시 라우터와 통신을 위한 설정 방법입니다.

*. 아래 Config 는 Cisco Router 2901 의 설정 예제입니다.

1. 먼저 card type 을 정의해 줍니다.

yourname#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

yourname(config)#card ty

yourname(config)#card type e1 0 1

yourname(config)#card type e1 0 2

yourname(config)#card type e1 0 3

2. 채널라이징을 해줍니다.

yourname(config)#controller e1 0/0/0 

yourname(config-controller)#channel-group 1 timeslots 1-8 ?

  speed  Specify the speed of the underlying DS0s

  <cr>

yourname(config-controller)#channel-group 1 timeslots 1-8 spe

yourname(config-controller)#channel-group 1 timeslots 1-8 speed ?

  56  56 Kb/s

  64  64 Kb/s

- 채널 그룹별 timeslot 값은 ISP 업체에서 제공하는 회선번호 및 채널 관련 정보와 일치해야 합니다.

- card type 및 controller 설정을 하기 전에는 해당 interface 가 나타나지 않습니다.

3. 해당 interface 에 ip address 를 할당합니다.

yourname(config)#int s0/0/0:1

yourname(config-if)#ip add 1.1.1.1 255.255.255.0

yourname(config-if)#int s0/1/0:1

yourname(config-if)#ip add 2.2.2.2 255.255.255.0

yourname(config-if)#int s0/2/0:1

yourname(config-if)#ip add 3.3.3.3 255.255.255.0

yourname(config-if)#int s0/3/0:1

yourname(config-if)#ip add 4.4.4.4 255.255.255.0

yourname(config-if)#end

4. interface 상태를 확인합니다.

yourname#sh ip int bri
