Hi all,
I have a Cisco 2821 router with VWIC2-2MFT-E1/T1 to connect to PSTN via E1 PRI. I think that all the configurations are OK (as I had done a case before and the configurations are the same) but Layer 2 cannot go to MULTIFRAME_ESTABLISHED.
Could anyone give me some explains or instructions.
Thanks and regards,
hoanghiep
