Kind of bored at work at the moment so I started mining some DSL network stats I found interesting. Number of active services - ~3,300,000 Number of active DSLAMs - 15,768 (plus another 1,377 dedicated network hubs) Least customers on a single DSLAM - 1 Most customers on a single DSLAM - 2,148 Smallest DSLAM in the network - the Extel LL-ADSL C8/R8-AS, 8 customers maximum Largest DSLAM in the network - the NEC AM31, 2304 customers fully equipped Some of the smallest DSLAMs are fed by a single 2Mbps link. The largest has multiple gigabit links available (although in practice they only need a tiny fraction of that) 33.3% of the network runs on what can be characterised as "low bandwidth" links, ie 2-16Mbps. The remainder is a breakdown of ATM STM-1, gigabit fibre, and EoSDH software configurable links via ad/dropmux as required. The network is comprised of the following hardware: Alcatel - 69.8% NEC - 29.2% Extel - 1% 66.7% of the network is ADSL capable. The ADSL1-only equipment can be so for a number of reasons, including older model electronics, insufficient bandwidth to offer high speed services, or locking to ADSL1 in software due to technical reasons. Some of the larger ISPs run around 6-700Mbps traffic across a balanced redundant gateway pair per state. Click to view full size! The smaller ones… are a bit smaller than that! (yes, that’s the *national* feed for one ISP.) Click to view full size!
