Fiber Optic Cable Attachment: Connect the fiber cables between the Flex Point T1/E1 converters. The transmit (Tx) must attach to the receive (Rx) side and the receive (Rx) side must attach to the transmit (Tx) side. Note: Use fiber cables that are compliant with the specifications that are outlined in fiber cable specifications.

Remote loop-back (R+L/LB) This switch will allow the entire fiber segment to be tested at either of the Flex Point T1/E1 converters without having to set switches on both units. When set in this mode of operation, the local unit is switched in a local loop-back mode. And in addition to the local loop-back mode of operation, the fiber Tx port will be further encoded to carry a remote loop-back protocol.
