How fast is DSL

Wie-DSL-Breitbandinternet-funktioniertWhat speed is DSL

DSL is the abbreviated word for Digital Subscriber line, Digital subscriber line or DSL works off a DSLAM or Digital Subscriber Line Access Multiplexer which server as an interface device connecting from your location to the DSL providers closest network aggregation point, commonly a Central Office. DSL speed is affected by the wire feet distance from your location to the underlying providers DSLAM. DSL providers require a DSL modem installed on your premises.

Distance is measured in feet and up to 20,000 feet or 4 miles from the DSLAM (typically located in a Central Office).
How fast is your DSL?:
20,000 feet would produce approximate bandwidth 128kbps upload, 384Kbps download.
15,000 feet would produce approximate bandwidth 256k upload, 768kbps download.
10,000 feet would produce approximate bandwidth 400k upload, 1.1Mbps-2Mbps download.
5,000 feet would produce approximate bandwidth 500-768k upload, 3M-5Mbps download.
1,000 feet would produce approximate bandwidth 768k-1Mbps upload, 5M-7Mbps download.
* Distances and speeds are estimated. Actual distance varies and is determined by actual wire feet.

DSL is best used for residential or a web surfer, as the downstream is much faster than the out or upstream.
DSL is also prone to more technical glitches than T1 and has a lower priority of repair for the carrier.

We recommend purchasing DSL through your Global IT representative, or going direct and using the local provider in your area for DSL. The local provider will offer the best QOS and customer service compared to competitors.

DSL does not offer service level agreements (standard of services) so it is a best guess effort.

You can receive static IP’s with DSL.

Dedicated Internet

Internet speed test

Today faster connections well over 100Mbps are becoming more common, and end users expect to test they are receiving the amount of speed they are paying for. When testing a connection faster that 100Mbps you may be surprised that accurate internet speed testing can be limited or affected by several factors.

Several limiting factors when testing bandwidth:
1. Limitations with NIC cardsspeedtest
2. Wi-Fi will almost always test slower than actual. This is due to wireless speed limitations, signal strength and packet loss
3. PC/Firewall/router duplex settings
4. Browser or device slowness (Cache)
5. Old cabling and patch panels limited to 10Mbps or 100Mbps
6. Slower 100Mb switches in between you and the core network switch, firewall or router
7. Other bandwidth traversing in/out from your networking to the internet needs to be factored into the math. For example, on a 100Mbps/100Mbps circuit and test your current usage lets say is about 20/50, your speed should reflect about 80/50.
8. Testing server speed limitations – Because testing servers are free, some companies do not like to pay for upgraded networks, servers and maintenance or additional bandwidth and so they limit the bandwidth for example to 50Mbps or 100Mbps. This bandwidth pipe will be shared across all network tests hitting that server at the same time, and that can be hundreds or thousands of simultaneous tests at one time.
9. Testing server test limitations – In most cases the testing servers are just not capable of testing speeds over 100Mbps per connection or test and when multiple tests are being run. The testing server or network is not capable of sustaining the many concurrent testing requests.

If you try internet speed testing using different speed testing systems, you will notice inconsistent results. This can be due to the current testing server load or software, geographical location of the server, or network configurations that may be different from the other servers.

Also, the most ideal way to test is to isolate out your network by connecting directly into the core switch or router and test from there. No other network devices should be connected during your test. This will rule out any local usage, viruses, or an incorrectly configured device. Read more on our website or test our network speed

Dedicated Internet

What is Dedicated Internet?

InternetWorldComputerIn order to understand what dedicated internet is, we must first define what it is not. Dedicated internet is not Dial-Up, DSL, Cable, or WiFi hotspots. All of these internet types are multiple clients sharing a single point of access to the internet. The speed varies based on usage. This means that if only a couple of people are using the same connection, the internet is relatively fast. However, if everyone decides to use it at the same time, the speed drops significantly. You will notice common slow times in the day, for example around 8 am as everyone starts to arrive at work or 11.30 before lunch or towards the end of the day and evening.

What separates dedicated Internet from the above connection types is that you are the only one using that connection to the internet. This means the speed is always going to be the same from your connection to the hub. When you purchase dedicated internet, you are guaranteed an upload and download speed. These speeds can vary from 1.5 Mbps to 10 Gbps.

Another great thing about dedicated internet is that you can have control over something called Quality of Service (QoS). This enables constant flow connections without timeouts, lag, or packet loss which are noticeable when connecting to websites, especially HTTPS websites that require a secure connection between computers. Voice over IP (VoIP) applications should only be using a dedicated connection and when doing so will sound crystal clear because there are no other users cluttering up your data connection. This is also helpful when streaming or uploading streams to clients by ensuring the viewing experience is smooth and clear.

Dedicated Internet lets you have your own private internet connection without having to worry about speed drops or VoIP and streaming issues. If there ever is an issue, you know it’s not because of your internet connection. It’s probably the website you are connecting to, or you may need to upgrade to a faster speed.
