Site Update

Main 4.5 meter Dish is back to service after we replace the ODU.

The original ODU get spoiled after a power failure.

We have did a User Acceptance Test with JSAT YSCC on 28 and 31 October 2005.

Future Plan We will do a maintenance on all the power cable and data cable

Proposed UDL Mesh Spectrum Allocation(nett spectrum usage unchanged, increased link BW)

Otherwise, we can reduce nett spectrum**Need to consider DVB-S MPEG-TS header overhead
