From what I can gather the bulletin was presented from New Broadcasting House - presumably also using their gallery but routed to air via MediaCity.
Out of interest would the bulletin have been sent via an OB truck to MediaCity or would they have had an ISDN link through to MediaCity?
There are internal Raman fibre circuits in/out of New Broadcasting House in Manchester and in/out of Media City in Salford I believe - so you just book a path between the two, just as you would between either location and any other BBC centre.
(NB ISDN is not used for broadcast video links as its data rate is orders of magnitude too low. ISDN delivers 64kbps or 128kbps - whereas most standard internal SD BBC vision circuits are 270Mbs (and previously were 140 or 34Mbs) - ISDN is routinely used for commentary and some audio contributions - though really you need to use the 128kbps dual-bearer system for semi-decent sound quality)

So where have today's bulletins come from?
