Well to be honest barring the issue of certain channels being placed not in correct order like SD feed being far apart from HD or some channels placed in wrong genre like DD North East bcoz of inadequate empty LCN slots being available ....apart from this LCN arrangement is very good on Airtel Digital TV Platform . 4 Digit LCN implementation will sort out all the above issues and even create proper gaps between different genres on EPG and hence will eradicate the need to change channel numbers of few channels at regular intervals to accommodate New Channels on the platform....also Channel Placement Order will be charged alongside as New Updated RIO agreement r signed with different broadcasters and accordingly Viacom18 HD channels and some others whose addition have been kept on hold bcoz of inability to change LCN of some channels of the concerned broadcaster/s across different genres to comply with slab signed for in RIO will also get addressed as New LCN arrangement will comply with Updated Slab Agreement as signed with various broadcasters thereby aligning these channels too in required order
