What is DSL? Top of page

DSL stands for Digital Subscriber Line. DSL technology increases the information-carrying ability of traditional copper wires. DSL enables high-speed multimedia services such as video-on-demand, very high-speed Internet access, distance learning, remote corporate LAN access, and videoconferencing. While wires carrying analog signals are generally limited to 56 kilobits per second, once the switch to digital is made and DSL technology is employed, these same wires can support data rates well over a megabit per second.
 
Types of DSL

Symmetric DSL (SDSL) - This type of DSL is for Business customers. The speed of downloading and uploading data is the same. This service does not use your existing phone line. A dedicated data line is installed for SDSL service.
 
ISDN DSL (IDSL) - IDSL is an option for business customers who are between 17,000 feet and 25,000 feet from the Central Office or who have fiber in their loop. IDSL is 128K only. You cannot upgrade to a higher speed.

Asymmetric DSL (ADSL) - This type of DSL is for Residential users. ADSL uses your existing phone line. You can talk on the phone and surf the Internet at the same time. Download speeds are faster than upload speeds.

How does it work? Top of page

DSL is a very high-speed connection that uses the same wires as a regular telephone line.

DSL is a distance-sensitive technology: As the connection's length increases, the signal quality decreases and the connection speed goes down. The limit for DSL service is 18,000 feet (5,460 meters), though for speed and quality of service reasons many DSL providers place a lower limit on the distances for the service.

You might wonder, if distance is a limitation for DSL, why it's not also a limitation for voice telephone calls. The answer lies in small amplifiers called loading coils that the telephone company uses to boost voice signals. Unfortunately, these loading coils are incompatible with DSL signals, so a voice coil in the loop between your telephone and the telephone company's central office will disqualify you from receiving DSL. Other factors that might disqualify you from receiving ADSL include:

Bridge taps - These are extensions, between you and the central office, that extend service to other customers. While you wouldn't notice these bridge taps in normal phone service, they may take the total length of the circuit beyond the distance limits of the service provider.
Fiber-optic cables - DSL signals can't pass through the conversion from analog to digital and back to analog that occurs if a portion of your telephone circuit comes through fiber-optic cables.
Distance - Even if you know where your central office is (don't be surprised if you don't -- the telephone companies don't advertise their locations), looking at a map is no indication of the distance a signal must travel between your house and the office. The total loop length could be more than the distance you are from the central office.

DSL Equipment

DSL Modem
This is the point where data from the user's computer or network is connected to the DSL line. The modem can connect to a customer's equipment in several ways, though most connections are USB or 10 base-T Ethernet connections.

DSLAM
The DSLAM or DSL Access Multiplexer is the equipment that really allows DSL to happen. A DSLAM takes connections from many customers and aggregates them onto a single, high-capacity connection to the Internet. DSLAMs are generally flexible and able to support multiple types of DSL in a single central office, and different varieties of protocol and modulation. In addition, the DSLAM may provide additional functions including routing or dynamic IP address assignment for the customers.

The DSLAM provides one of the main differences between user service through DSL and through cable modems. Because cable-modem users generally share a network loop that runs through a neighborhood, adding users means lowering performance in many instances. DSL provides a dedicated connection from each user back to the DSLAM, meaning that users won't see a performance decrease as new users are added -- until the total number of users begins to saturate the single, high-speed connection to the Internet. At that point, an upgrade by the service provider can provide additional performance for all the users connected to the DSLAM.

How much does it cost and what does it include? Top of page

Galaxy Internet Services offers DSL at an exceptionally competitive price. The Business DSL service includes 50 Megabytes of web space for your Company webpage and up to 10 free email addresses for your employees "@yourcompanyname.com". It also comes with a free dialup account for employees to use on the road or from remote locations. The value of these free added services is $34.90 per month. Below is a table of the monthly cost for each DSL speed that Galaxy offers:

Speed Email Web Hosting Starting At Setup Fee
Up to 384k 10 Addresses 50 Megabytes $149 Yes
512k 10 Addresses 50 Megabytes $199 Yes
768k 10 Addresses 50 Megabytes $249 Yes
1.1M 10 Addresses 50 Megabytes $299 Yes
1.5M 10 Addresses 50 Megabytes $399 Yes
2.0M 10 Addresses 50 Megabytes $489 Yes

Is DSL available at our location? Top of page

Our DSL service is widely available on the East Coast. Please call to find out if it is available at your location. One of our Sales Representatives can pre-qualify your address over the phone.

Reasons why DSL may not be available at your location.

1. The Phone Company's Central Office in your town or city must have the equipment for DSL (DSL Access Multiplexer). Not every Central Office has this equipment. 2. Even if the Central Office in your town has the DSLAM you need to be within 17,000 feet for SDSL or 25,000 feet for IDSL. 3. Other factors that may impact DSL availability are fiber optics, load coils, or no facilities (i.e. you may not have an available copper pair at your location or the DSLAM at the Central Office may not have an available termination point for your circuit).

What is the installation process? Top of page

To use Galaxy's DSL service you need a data line installed at your location and a DSL router which connects to the data line. The following is the sequence of events to have DSL installed at your location:

Step 1) Our service department will contact you in 2-3 weeks from the time you placed the DSL order with a status on your new data line, most orders should have had a DSL data line installed by Verizon at this stage.

Step 2) We will then contact you again 7 to 10 days later to schedule a date and time for our technician to come out and install the DSL Router at your location.

Step 3) Our service department will email or fax you the DSL set up instructions for your computer/network.

Step 4) If necessary Galaxy's technical support department will work with you over the phone to help you with the final configurations for your computer/network.

What equipment is needed? Top of page

Galaxy will provide a full-featured DSL Router to connect your computer/network to your new DSL service. In order to connect to this Router, you will need the following:

1) Ethernet card or USB Ethernet adapter installed in your computer. (These are typically available for $25 to $50 at most computer stores).

2) Ethernet cable to connect your computer to the DSL Router (10base-T/RJ-45)

If you are connecting the Router to an existing LAN Hub or Switch, you will need an Ethernet Cross-Over cable (10baseT/RJ-45 type).

Galaxy recommends purchasing the Ethernet card once Galaxy has notified you that your local bell operating company approves your DSL circuit.

Please plan accordingly, so your installation will go smoothly.

Do we own the router or does it remain the property of Galaxy? Top of page

In most cases the router remains the property of Galaxy Internet Services. The router must be returned if you terminate your DSL service.

When does billing begin? Top of page

A refundable security deposit equal to one month of service is due within 10 days of the date that you submit the DSL contract. The setup fee and first month of service are due within 10 ten days of the day that your DSL router is active and can receive and transmit data over the Internet.

How secure is DSL? Top of page

The DSL router comes configured with what is called Network Address Translation (NAT). The router has one external IP address which is exposed to the Internet, but internally there are over two hundred private IP addresses available for your workstations. Because there are private IPs behind the router which are not exposed to the Internet the DSL router essentially acts as a basic Firewall/Proxy.

What if my business moves? Top of page

There is a $300.00 relocation fee. The re-provisioning process will take 3-6 weeks.

What if I need to cancel before the One Year Contract is up? Top of page

The cancellation fee is $300.00 if you cancel before the one year contract is up. There is no cancellation fee if you cancel after one year.

What if I want to change the speed of the DSL service? Top of page

There is a $100 dollar fee to change the speed of your DSL circuit. (Note: this fee may be reduced or waived if you are significantly increasing the speed of your circuit.)

What if I need extra IP addresses? Top of page

The DSL router can be reconfigured to use public static IP addresses. There is a  $25.00 fee to reconfigure the router from NAT to static IP addresses unless the request is made before the installation of the router. (Note: You do not need static IPs to run your own web server or mail server or to use PC anywhere as long as you are not running more than one of each.)

Can my business run its own web server or mail server? Top of page

Yes. If you transfer your Company domain to Galaxy we can do Address and/or MX records to the IP of your router and then map the appropriate ports to the internal IP address of your server. If you have a real static IP on your server we can do Address and/or MX records directly to the public IP address of your server. If you choose not to transfer your domain to Galaxy the web hosting company you use can do Address and/or MX records as described above.

Does Galaxy offer Virtual Private Networking (VPN)? Top of page

Yes, Galaxy does support VPN. Please call to find out more about our VPN capabilities.

Do you support PC anywhere? Top of page

Yes, Galaxy does support PC anywhere. Our DSL routers have dedicated ports for PC Anywhere that can be opened and mapped to the internal IP address of the PC Anywhere computer.
