Currently I have a VWIC2-1MFT-E1 and VWIC2-1MFT-G703 to install a voice link E1, and a Cisco 3845 router equipped with PVDM2-32. The only information I have is that the E1 will be channeled and unbalanced, so I would like to know which of the two interfaces I use, what configuration and if I also need something else.
Thank you very much for the attention.
