GETTING FDMA WORKING ON A CPN
I will show here the basic configuration of how to get FDMA working on a Lot 10 CPN. All CECOM documentation only shows how to get a JNN working but as CPNs don’t have a GPS to provide timing, we have to do things a little differently. Cabling TFOCA-2 runs from Port 1 on the LOS case to J1 on the STT. In our LOS case, we had to use the spare fiber pair to connect to the CTM-100/C. Serial cable connects from NT2R Serial0/0/0 to the LOS case’s Channel 1 Red. Serial patch from Port 1 NRZ to Channel 1 Black (all on the LOS case). FDMA modem and CTM-100/C installed as labeled in the STT. KIV-7M installed as labeled in the LOS case, COMSEC loaded, and strappings matching the HUB. CTM-100/C Configurations The following setup will allow your CTMs to pull timing through your FDMA modem.
