| Re: What is the capacity/month of a D2 line? said by sturmvogel:What is the capacity/month of a D2 line ? 38mbps * 60 sec/min * 60 min/hour * 24 hr/day * 30 days/month * 1byte/8bits = 12312 GB/mo. Factoring out 15% overhead: 10465GB/mo.
Average subscribers per channel in 1999: 1000. Average subscribers per channel now: 250.
You can do the math from there. | |

kudos:1 | Re: What is the capacity/month of a D2 line? The actual capacity is 43 something. The 38 is after the 15% so we're looking at 12,000 GBytes/month, or 48 users each consuming their 250GB "cap". | |

| | | | | | Re: What is the capacity/month of a D2 line? so what does 2% mean? | |

| | | | | | | Re: What is the capacity/month of a D2 line? 2% is considerably less than 10%.

715/12312GB = 5.8%
Assuming there are 250 people per downstream channel (based on averages), on an equal divide, that's 1/250 or 0.4%
So you have someone who represented 0.4% of the paying subscribers on that segment consuming 5.8% of total capacity.
I don't believe the 250GB cap was ever meant to be a true bandwidth allocation per subscriber, it's simply a point at which to look at taking action to stop the bleeding. | |

| | | | | | | | Re: What is the capacity/month of a D2 line? nothing? | |
