Vdsl installation

These loading coils are incompatible with DSL signals because the amplifier disrupts the integrity of the data. This means that if there is a voice coil in the loop between your telephone and the telephone company's central office, you cannot receive DSL service. Several other factors might disqualify you from receiving ADSL:. In the next section, you'll find out why. VDSL can achieve incredible speeds, as high as 52 Mbps downstream to your home and 16 Mbps upstream from your home.

But VDSL's amazing performance comes at a price: It can only operate over the copper line for a short distance, about 4, feet 1, m. The key to VDSL is that the telephone companies are replacing many of their main feeds with fiber-optic cable. In fact, many phone companies are planning Fiber to the Curb FTTC , which means that they will replace all existing copper lines right up to the point where your phone line branches off at your house.

Instead of installing fiber-optic cable along each street, FTTN has fiber going to the main junction box for a particular neighborhood. The gateway takes care of the analog-digital-analog conversion problem that disables ADSL over fiber-optic lines. It converts the data received from the transceiver into pulses of light that can be transmitted over the fiber-optic system to the central office, where the data is routed to the appropriate network to reach its final destination.

When data is sent back to your computer, the VDSL gateway converts the signal from the fiber-optic cable and sends it to the transceiver. All of this happens millions of times each second! On the next page, you'll find a chart that lists the variations and how they compare to each other. There are several variations on DSL technology. In fact, there are so many that you will often see the term xDSL , where x is a variable, when the discussion is about DSL in general.

As you can see, VDSL provides a significant performance boost over any other version. But for VDSL to become widely available, it must be standardized. DMT divides signals into separate channels, each 4 kilohertz KHz, or 1, cycles per second wide.

One way to think about it is to imagine that the phone company divides your copper line into different 4-KHz lines and attaches a modem to each one.

You get the equivalent of modems connected to your computer at once! Each channel is monitored and, if the quality is too impaired, the signal is shifted to another channel. This system constantly shifts signals, searching for the best channels for transmission and reception. In addition, some of the lower channels those starting at about 8 KHz are used as bidirectional channels, for both upstream and downstream information.

Monitoring and sorting out the information on the bidirectional channels, and keeping up with the quality of all channels, makes DMT more complex to implement than other carrier technologies, but also gives it more flexibility on lines of differing quality.

ADSL " ". Transceiver - At the customer's location, there is a DSL transceiver, which may also provide other services.

Bridge taps - These are extensions, between you and the central office, that service other customers. Fiber-optic cables - ADSL signals can't pass through the conversion from analog to digital 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. UniFi service installation is subjected to location service coverage availability as well as technical and civil testing requirements.

Installation appointments are subjected to earliest time slot availability. Customers will be required to call TM back once the work is completed, for the UniFi installation appointment. TM will not be responsible for providing concealed internal wiring during UniFi installation.

All related charges will be borne by customers. Customer or an authorized representative must be available for the duration of the UniFi service installation so as to understand and sign-off on the installation process. Charges for Change of Appointment: Any installation appointment that is cancelled or postponed less than 24 hours of the scheduled appointment will be subject to a RM penalty fee.

Re-appointment will be subject to time slot availability and the RM installation fee will be imposed. All UniFi equipment provided will be subjected to a one 1 year warranty period.

The customer is however, required to assist in providing the TV and at least a four-socket extension cord to complete the installation.

Only 1 TV set will be installed with wired broadband connection Only TM provided phone will be installed for Phone service. If customer unreachable during first TM visit, application will be cancelled on the 8th day from 1st appointment date.

Please contact option 3 within said period to avoid order cancellation. Customer shall indemnify TM against a claim by any party including building owner or management corporation for any damage not due to the fault or negligence of TM.
