I have a situation here where one of my customer are using a Huawei 18-31 router and want to make an ISDN connection to HQ, which is using a Cisco 3700 router.
Can somebody help me with an example configuration? I've already try with the attached config, but the ISDN will only lasted for 1-3seconds and then disconnected.
Is anyone have done this before? Connecting ISDN using Huawei and Cisco?? If yes, do you mind sharing the config example with me. Thanks.
Hi Azmir ,
first and foremost thing is check the username and password configured on both the routers.
2.have you configured dialer-list 1 protocol ip permit on both ends.
dubug isdn q921 and debug isdn q931 on 3750 helps in troubleshooting the isdn connection.
can you enable above mentioned commands and paste it in netpro.
I've already check and done what you tell me to do.
But unfortunately debugging at the HQ Cisco router doesn't come out with any messages ( I've already turn on Ter Mon and apply command debug isdn q931 & debug isdn events )
Attached is the Huawei debugging messages.
