Detailed Information on DSL Splitters

ADSL2+ / VDSL2 Splitter

This page provides detailed information about the DSL Splitters offered for sale on page Materials and Tools for Your Telephone Wiring Project These splitters can be used for the DSL wiring installation configurations discussed on pages An Overview of Wiring Requirements to Support Residential DSL Service, Installing the DSL Splitter Near the NID, DSL Splitter Installation in a Star Topology, and Installing the DSL Splitter Near the DSL Modem/Router.

Whole-House "Master" Splitters

These devices offered at HomePhoneWiring.com are true "whole-house" splitters (a.k.a. "master splitters"). If comparing to other "splitters", make sure you are comparing equivalent devices. A true "whole-house" splitter is a filter designed and packaged to support installation in such a manner that all of the voice phone jacks and wiring are isolated from DSL jacks and wiring by one single device. Many devices sold by other vendors are referred to as "splitters", but are simply microfilters with separate voice and DSL jacks, a filtered jack for the phone and an unfiltered jack for DSL. Some are specially designed so that they will only attach to or replace a wall-mount "kitchen" type jack, which is probably not the jack type used where you plan to locate your DSL modem. These other devices probably do not have screw terminals to support connecting cable to extend the DSL data to another location. Some are just a "kit" with a duplex adapter to plug into a wall jack and a normal microfilter to plug in one side of the adapter. While these other devices can technically be called "splitters", they are only suitable for use when the voice signal will only be used at that single location unless microfilters are used at the other locations. Those other devices do not protect the DSL data from high frequency interference generated within the voice wiring and will probably not provide any significant advantage over the normal microfilters that were probably supplied by your DSL provider. In contrast, when the splitters sold at HomePhoneWiring.com are installed in the method recommended on this site, the DSL data is isolated from the voice portion of the inside wiring. This can greatly enhance both DSL and voice signal quality. If comparing splitters, make sure the devices you are comparing can be installed as true "whole-house" splitters. Of course, you should probably also consider whether the vendor can/will respond to requests for advice and assistance. There's already a wealth of advice at HomePhoneWiring.com and I definitely respond to requests for assistance from my customers.

The ADSL2+ / VDSL2 Splitter has RJ-11 jacks for the LINE, PHONE, and MODEM connections and IDC connectors in parallel to each jack. The modem connection can be made with hardwire connection to the IDC connecitons or a 6P2C (RJ-11) line cord between the DSL modem and the MODEM jack of the splitter. The line will normally be connected with a hardwire connection to the IDC conneciton. The LINE jack of the splitter can then be used to temporarily connect a phone or other equipment to test and verify the connection. The cable to the phones will noramlly connect to the IDC connector, but the PHONE jack of the splitter can be used to connect a single phone or any other device that need dial tone in the area of the splitter or to patch to any a structured wiring panel or other device that interconnects the phones.

All permanent wiring will normally be connected direct to the PS-36i-01 without of using the modular jacks. The IDC terminals allow connection of unstripped wires without tools. To terminate wires on the IDC terminals, you simply lift the front of the connector (see left connector in picture at right), insert the unstripped wires in the holes (one wire each), and press down to close the connector. The teeth of the connector will cut through the insulation and connect to the wire.

The PS-36i-01 includes robust ring-trip protection to eliminate video pixelization due to loss of packets that can occur when answering phone calls in the middle of a ring signal. For a technical explanation of "ring-trip" conditions, refer to www.wilcominc.com/documents/WILCOM_FAQ_Ring_Trip-web.doc.
