The 40 driver outputs of the MGO module of channel A are connected to the MRC-TS modules
at Plug A using a 40-way ribbon cable via the appropriate MUT module at the rear of the rack.
The 40 driver outputs of the MGO module of channel B are connected to the MRC-TS modules
at Plug B using a 40-way ribbon cable via the appropriate MUT module at the rear of the rack.
