The NTTregional company (east indian west US),for the generalhome which uses the optical fiber data transmission service.It spreadsthe communication service by the optical fiber to general home "FTTH" (Fiber To The Home) it is the service which actualizes plan.
With flat-rate schedule, as for transmission speed being highest, 100Mbps. In order with courseof partto share the access line with the group of users, as for month amount rent it is low amount, transmission speed somewhat becomes unstable. However, as for transmission speed although it has an influence on the utilization circumstance of the user around,like ADSL as for problem at quality level of the circuit because it is not, you can obtain the connected environment which is stabilized at relatively fast transmission speed.
ISDN/PPPoE connectionis adopted sameas ADSL,NTT offers only the access line.As forconnection on Internetbecause Internetservice provider does, separate connection charge
There is a type such as BASIC type, share the 10Mbps circuit with the group of users family type, the apartment type which shares the 100Mbps circuit inside the multiple dwelling house and monopolizes the 100Mbpscircuitto for SOHO to the regionalIP netthe business type where the group of users share the 100Mbps circuit.
Furthermore, as for transmission speed of when 10Mbps is exceeded rather even in BASIC type, because it is, withthe old rooterthere aretimes when throughput of the rooter does not overtake. In this case,as forthe bottleneck it is not the circuit andbecauseit means to occur in the rooter, when transmission speed is slow strangely,it isnecessary to try doubting the rooter.
