A leased line should be more stable than a DSL connection. While there may be guarantees for a DSL connection, a leased line has typically more enforceable guarantees and you should get more decent technical support or even rebates for downtime. Don't expect bursts with a leased line, though. If you get a 64kbps leased line, that's it. While also fairly stable (although nowhere near leased line quality), DSL connections should be more "burstable" and if you have a good connection, you should be able to saturate your line as much as the telco's cap and total bandwidth will allow you. DSL is also more dependent on the quality of your telephone line, and your distance from the nearest telco hub. This is the reason why before getting a DSL connection your telephone line must be prequalified first. And even if your line is qualified for DSL, the farther you are from the telco hub, the more erratic your connection will be. With a leased line, on the other hand, they will actually lay cable down for you, so distance-related issues are taken into consideration beforehand, so again quality should be much more consistent. Most of the time the difference between a DSL connection and a leased line is significant, though, so you will have to factor this in depending on your intended use. Here at The Leather Collection, for example, we have a corporate PLDT 256kbps DSL connection. While there are downtime, and there are no guarantees about this or about transfer rates, this is much cheaper than even a 64kbps leased line connection, and we are definitely not limited to "just downloading". > follow up question, how may PCs do think that a 64k leased line w/ 32 > CIR can support? It depends on the usage patterns of your users. On typical days our MRTG graphs report an average of between 5KB/s to 10KB/s going through our DSL connection. But when I download ISOs even if the rest of the company is asleep I saturate our 256kbps connection by doing almost 30KB/s until the downloads are done (typical ISOs are 650MB each). Considering the costs, and considering that you probably already have a fairly reliable upstream connection, you may want to try DSL out to supplement your main link. This should give you an idea about the quality of the DSL connection to your servers (if you plan on using this in the University of Baguio). > pasensya na medyo off topic mga questions ko .... foul na ba ito? please > let me know :) No, your questions are not foul. They are off-topic, though. --> Jijo -- Federico Sevilla III : <http://jijo.free.net.ph/> Network Administrator : The Leather Collection, Inc.
