-This leg of the [[Current Broadcast Network]] carries the video and audio feeds from the [[G/046|studio]] through to the [[Broadcast Hub|central distribution hub]] where it is distributed out to the various destinations on campus. It is now the oldest part of the network, having been in it's current form since the station moved to [[G/046]] in 1994.

 In P/S/016 the audio cables are joined straight on to the 6-pair Rediffusion audio contribution cable which runs to the [[Broadcast Hub|Hub]] (originally to LTC). The unbalanced video is fed into a line driver in order to drive one half of the shielded twisted pair Rediffusion video contribution cable to the Hub.
-These contribution cables go back up into the ceiling void, and then back along the corridor to the concourse, and into the pipe under it, now taking the right turn by the porter's lodge to head through the building and out into the covered walkway towards Central Hall.

This duct goes across the bridge (exactly how is unknown), then into the underground duct past the front of Central Hall, before coming back up to reach the Hub. This run consists of unbroken Rediffusion cabling.
-The two Black Redddifusion cables emerge from physics (it looks like from the roof!), and are draped onto the covered walkway, where they go into a hole (lake side) inside the walkway, over the bridge. Then out of a hole on the other end of the bridge(on the side facing the main bit of the lake), this is draped onto central hall stairs in a nice pile (Thankyou contractors for laying the cable across the bridge!).
-What would have been the continues two reddiffusion cables start off in a man hole (whose cover is 2 foot from the Vented doors of central hall) and travel the underground duct past the front of Central Hall, before coming back up to reach the Hub. The run consists of Rediffusion cabling. It just needs connecting from the stairs to the man hole.

+In 2011, the long-awaited construction of a new SU building on the site of the old dining room and bar resulted in the removal of a section of covered walkway connecting Physics and the now-James College building. The cabling running through this section was cut, severing the connection from G/046 to the rest of the network, and was eventually left coiled on the roof of the new building upon it's completion in June 2012. No attempt was made to reconnect the lines as the network was by then rarely used, with IP distribution becoming the norm. Cabling remains on the roof to this day.
+In September 2016, the line coming into G/046 were cut in an effort to tidy up the control room cabling. The exterior cabling is still present.
