application)
NG Services : Converged (quad play- voice, data, video & mobility)
NG Access : High speed (Broadband) IP based connectivity
(ADSL,VDSL, WiMax, Cable TV, FTTH)
NG Transport : Ethernet, IP-MPLS, RPR, T-MPLS
NG Mobile : 3G+, 4G
NG Internet : IPv6
NG Interconnect : Capacity and Quality based
NG Licensing : Unified, Converged
