I have a fibre remote ipe card that is tied to a remote site cabinet. The vendor we are leasing the fiber between the sites from is going the have to break the link between the 2 sites to do some repairs to the fiber. What will i need to do, to have the pbx and remote shelf ready for the link to be down. Or will unhooking the fibers on both ends and rehooking them back up after they are finished be all i need to do for the two ends to link back up?
