Advice 1: Why you need a splitter

To be able to connect to the Internet through a telephone line, one modem is not enough. Splitter - a device that will split the signal from the server and the other phone while the Internet connection speed and lack of interference with conversation.
Why you need a splitter
Once I developed a regular telephone, no one could come to the idea that the telephone wires ever be used for digital signal transmission. Therefore, for the functioning of the Internet and phone on one line I had to use a special separation device.

Why you need a splitter

If a high-frequency signal (Internet, ADSL) will run simultaneously with low-frequency (PSTN), the phone will constantly hear interference in the form of noise (the electronics of the phone will "try" to decode the RF signal). On the other hand, the low frequency component of the signal will "slow down" the transfer of information from the server, because the modem will count bass signals for the mistake should be corrected.

To protect both signals (analog telephone and a digital computer) from the mutual influence of the used filter (or splitter) connected between the telephone cable, modem and telephone handset. Externally, the crossover is a small box made of plastic that has one input for the telephone cable and a pair of outputs for camera and modem.

How does splitter

Getting on the input frequency band filter divides into 2 parts: one for the telephone signal, the other for the ADSL signal. As a result of division, the device emits for each output socket of the appropriate frequency. Telephone equipment, which includes machines, Fax machines, answering machines, etc., receives frequency range to 3400 Hz, and the modem – all frequencies by 25000 Hz.

If the room has several phones on the same cable, the splitter placed at one outlet. In this case I have to pull a separate wire to the ADSL modem outlet. It is not very convenient, since it will have to shift to crossedout) telephone line to the modem and phone can work simultaneously. The problem can be solved through the use of microfilters. These devices have a single output, one input. Such a filter is mounted in front of each telephone handset. Sometimes, for convenience, manufacturers are producing a telephone wire, where already built a microfilter in the form of thickening. In some cases, the device is mounted directly in the junction box. Splitter, in fact, advanced microfilter. The latter works exactly the same as his colleague: divides the frequency range to allow the phone high-frequency signals; and prevents the penetration of low frequencies to the modem.

Advice 2: How to connect a splitter

Connecting the Internet to your computer through ADSL connection is performed by connecting a phone line and modem. To ensure correct operation of the modem and phone at the same time, you should use a splitter. Splitter is a kind of filter which can separate frequency channels on a few branches.
How to connect a splitter
You will need
  • - ADSL modem;
  • - connecting cable;
  • - splitter.
Modern PBXs allow for the transfer via a single cable several frequency signals, for example, a standard telephone line and Internet. A few years ago this technology was still unknown, so access to the Internet and making calls to the subscriber's number were produced separately. Today splitter allows you to perform this "category of priorities."
For good communication, to exclude all the twisted wires on the path from the PBX to connect to the network adapter. Any breakage even part of the wire leads to the deterioration of the incoming signal, which can lead to unstable operation of the Internet (slow loading speed, increase ping, etc.). In the presence of adhesions or twists it is advisable to call a wizard that will allow you to replace the phone cable is continuously running wire.
The most favorable location of the telephone sockets for the connection of the splitter is the location of the computer as a splitter divides the telephone cable into two components, one of which connects with the network adapter. The remaining cable is connected to the telephone set, which can be transferred to any place by long wires.
Take in one hand and a splitter, and in the other hand the main telephone cable. Connect the plug of the connector cable LINE splitter. On the opposite side of the splitter you will see two connections: for a modem and a landline phone. Connect the plugs of the devices to the corresponding connectors of the splitter (PHONE and MODEM).
After connecting the splitter to the phone line and powered it devices, it is necessary to check operability of the created circuit. Turn on the ADSL modem, and then turn on the computer. If when downloading files from the Internet to your landline phone can receive calls, and hanging up you can share information, hence the connection was properly organized.
