Using Fiber to Copper Voice Transceivers in RightFax 9.0

if you are wondering what fiber to copper voice transceivers has to do with RightFax, let me quickly clear it up. Due to distance constrains with UTP/STP cable between PABX and the Brooktrout E1 card, Fiber Optic cable has to be used for the connectivity. However as the Brooktrout E1 Fax card does not have a fiber outlet Special Voice transceivers has to be used to convert the fiber optic cable signaling to UTP.

Distance more then 200-300 meters is usually considered as the max distance between for a UTP/STP. If you are troubleshooting E1 connectivity on the RightFax server with the brooktrout card and PABX setting fine, verify the distance between the RightFax server and PABX and if it is more then the above distance then you can use the above solution.

Note: Even if you are using the above scenario, the E1 card configuration will still remain the same. However, PCM copamding setting should be changed according to the region, A-LAW or MU-LAW. The default is MU-LAW To change the PCM companding setting follow the below:
