At locations where the TCF is removed from the Earth terminal, portions of the DCSS will be located at both the TCF and Earth terminal, interconnected by a radio relay or cable. Troubleshooting and corrective maintenance are completed to the module level by station forces with the unit in place. Operational configuration provides additional NRZ data rate options of 3.088 Mbps per port and 6.176 Mbps per port. The multiplexer set operates in both synchronous and asynchronous modes with any combination of port data rates whose combined rate does not exceed 12.352 Mbps. Synchronous data is multiplexed into the MBS using a fixed-rate conversion.
Asynchronous data is multiplexed using positive bit stuffing.
