Alternative routes before EllaLink comes into operation
would be one of the Brazil-Africa cables (one to Cameroon,
the other to Angola) and then to Europe.
Are you talking about SAex?
There is SACS as well.
Brazil-Angola cable is SACS, which for an European route would be paired with WACS to go from Angola to Portugal.
Brazil-Cameroon cable is SAIL, which to get to Europe would be paired with ACE to go from Cameroon to Portugal or France.
