Hi all…
Can I have a E1 to mikrotik? because the E1 has a WIC-1T interface end point, and we know mikrotik has ethernets port so I did search on the web and I did not see any cable converter or something stuff, so if you have some clues it would be great!!!
Thanks and have a nice day 
T1 is 24 channels, and E1 is 30 ( I believe so ). You need an E1 interface, not a T1 interface. You cannot interchange them. I believe the only synchronous interfaces that mikrotik supports are FarSync I believe. Look in the manual for synchronous interface support.
Yes, only Farsync are supported,
