A. Entre ao Cisco 827 e do modo enable, emitem o dsl operating-mode xxx do comando cisco ios onde xxx são seu tipo da codificação de linha.
Nota: A interface ADSL 827 Cisco, por padrão, está no modo de detecção automática e detectará automaticamente a codificação de linha a ser usada quando se conectar ao seu Provedor de Serviço da Internet (ISP).
O seguinte exemplo mostra a configuração da codificação de linha para o G.LITE.
Router>enable Router# Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#interface atm 0 Router(config-if)#dsl operating-mode ? ansi-dmt ANSI full rate mode auto auto detect mode itu-dmt ITU full rate mode splitterless G.lite mode Router(config-if)#dsl operating-mode splitterless Router(config-if)# exit Router(config)# exit Router#write mem Building configuration... [OK] Router#A configuração da exemplo seguinte mostra um Cisco 827 após o seu configurado para o G. LITE.
Router#show running Building configuration... Current configuration : 1198 bytes ! version 12.2 interface ATM0 no ip address dsl operating-mode splitterless !--- This is G.LITE mode. ! endUma outra maneira de verificar que a interface ADSL do Cisco 827 reage do modo do G. LITE é emitir o ATM 0 do controlador da mostra do comando cisco ios. Na saída você deve ver (G. Lite). Por exemplo:
