> ITU G.983 ATM-PON approved standards:

> G.983.1(1998): optical layer, transmission convergence layer, and ATM layer for BPON systems

> G.983.2 (2000): operations channel protocol and message set (OMCI) between the BPON OLT and the ONT

> G.983.3 (2001): alternative wavelength plan including additional wavelength band for downstream video broadcast or for bi-directional transport of data using DWDM

> 155 symmetrical to 622 Mb/s asymmetrical shared by homes for voice and data

> Guaranteed Quality of Service through ATM: CBR, VBRnrt, VBRrt, UBR…

> FSAN committee as a major source of input (Service Provider oriented)

Video over RFVideo over RF

> BPON OLT’s serve Voice, HSI and CATV video

> Can deliver video from a RF video head end

> Utilizes 1550nm transport for analog and digital video services out of the Coax connector on the ONT

> Leverages mature CATV infrastructure

> No home wiring re-work

> Can be deployed with or without a set top box

> Channel switching at the STB or TV

> US RBOC purchasing of this approach will improve component cost (FTTP)
