DSL of most of the companies is shared with contention ratios like 1:5 etc. The 512 kbps of connection provided by LDN or PTCL costs Rs. 1200/ only and one gets average speed of 40 to 55 kBps (320 kbps to 440 kbps). Whereas a CIR or un-shared line of 512 costs more than Rs. 15,000/-. It gives constant 57-59 kBps.
I want to ask why is there so much price difference when the bandwidth diff. is only of 15-20 kBps?
If 512k normal DSL is shared among 5 users, how can each get 40+ bandwidth all day long?
