Or use the same approach you had suggested earlier but introduce some tracking objects to monitor the status of your links or simply put the concept of IP SLA as suggested by tony

Hi Hugo Lombard,
At client side, both links terminate on one router mostly cisco 1721 or 1841 series. On NOC side all links terminate on same router but mostly specifuc sub interfaces. Like one serial with different sub-interfaces or Vlans Sub interfaces in terms of fibre connection
Ah, in the case of the VLAN interfaces, you're probably running that trunked into a switch then, and the VLAN subinterface won't show a DOWN when there's a problem?
I think in this case, you're going to have to run an routing protocol of sorts, that will actively monitor the state of the connection, and switch to the serial when the fiber goes down.
Do you manage all the routers on the customers' sides?
