Legacy telephone services are transmitted in Gigabit Passive Optical Network (GPON) by non fractionated E1 data streams, known as native Time Division Multiplexing (TDM), or by circuit emulation service (CES). We propose a new technique for transmitting those E1 streams in a more efficient bandwidth allocation scheme, by fragmenting E1 signals without using circuit emulation techniques. The proposal, based on the combination of spatial and temporal switching, has been simulated in a hardware… CONTINUE READING
