DSL (digital subscriber line) is a technology that uses standard
copper telephone lines with a local loop network that is digital
in nature. There are several types of DSL available:
xDSL |
Generic form of DSL meaning the x can represent the A, S, I, etc.
|
SDSL |
Synchronous DSL, the upload and download speed capacities are the same.
This is the type of DSL offered by Msen.
|
ADSL |
Asynchronous DSL, the upload and download speed capacities are
different with the download capacity (web-browsing speed) being
faster than the upload capacity (sending email speed). This is
the least expensive form of DSL and is generally sold as
residential service.
|
IDSL |
ISDN DSL which uses ISDN transmission technology to deliver data
at 144 Kbps in an ISDL modem bank connected to a router. Used
when a business is too far away for SDSL.
|
Since a DSL connection requires a DSL-ready Central Office in your
telecom provider's facilities, DSL is not available in all geographical
areas and available top speeds vary.

The speed of the local loop to the customer imposes a maximum limit on how fast the connection can possibly go. This is
knowns as the Burst Information Rate (BIR). A customer connection will never be faster than the BIR, although it can be
slower. The maximal speed available on this loop is determined by current DSL technology and is limited by distance from
the central office.
|
The Commited Information Rate (CIR) is the minimum amount of bandwidth reserved for the customer's use from Msen to the
Internet. A customer connection should not run slower than the CIR but it can be faster, if extra bandwidth is available.

Business sDSL services
DSL is typically
oversold by Internet Service Providers, much like Frame Relay.
Many ISPs do not permit the customer to choose their level of service, simply giving the customer whatever is available
and claiming that they are providing a specified level of service. Msen takes a different tactic, we let the customer
choose how much of the bandwidth they always want available. We provide 2 levels of commitment:
50% CIR |
Good balance between cost and quality. Targetted at organizations that primarily do web surfing and file transfers.
Not recommended to provide services.
|
100% CIR |
Highest class of service. Targetted at organizations who want to replace a leased line of similar capacity or provide
web services.
|
All Msen DSL lines are provisioned by default with 8 IP addresses, of which 5 are usable
by customer equipment. Additional IP addresses are available.
Hardware ranges from $750.00 to $1000.00 depending upon customer requirements.
Residential ADSL services
Msen is not offering residential ADSL service at this time.
