Redundancy applied at the wrong place. Now it's "whatever provider
has problems, you will have problems in *both* cases".
Since you have another circuit available, more useful redundancy would
be "4x STM1 from provider A -> GE A, 4x STM1 from provider B -> GE B".
If that's not feasible, you could check with your STM<->GE conversion
box whether it can be configured to drop the GE circuit if not all 4 STM1
are up - I can't say whether your box can do this, but it might
(similar to the "multilink min-links..." setting in a cisco dialer).
