EMX Broadband Multi-Access System EMX - an introduction EMX is an advanced, state-of-the-art, Broadband copper Multi-Access System based on newest SHDSL technology of transmission. The EMX system is the most economical solution for introducing Broadband Internet Access in combination with POTS telephony. EMX provides multiple POTS services in combination with Ethernet-data channels with speeds up to 2 Mbps - all over one copper pair! It allows the carrier to deploy affordable Broadband solution without major investments in copper infrastructure in a very simple and efficient way. PROBLEM: One of the main issues telcos and/or internet providers are facing today is how to increase the Broadband Internet penetration. The main problem for incumbents (ILECs) is lying in copper access network. Many times there is a lack of free cables and sometimes clients are too far away from the switch to be reached by ADSL broadband technology. Also cables are soon getting "saturated" because of ADSL high Power Spectrum Density. Besides that, there are many customers connected over narrow band pair-gain systems. There is no way to provide ADSL Internet access to the customers having telephone service provided over ordinary narrow band pair-gain system! For CLECs on the other hand the main problem is how to use the rented cables in most economical way.

EMX system answers to all above mentioned problems. In first place EMX system is a very cost-effective and resource-saving method of servicing multiple Broadband Internet customers over existing copper lines. In the classical ADSL scenario, for example, 4 separate copper twisted-pairs are needed to connect 4 clients with Internet access. On the other hand EMX's innovative design can service up to four POTS & Broadband Internet clients over only one twisted copper pair. By using G.SHDSL technology it also ensures best performance in different kind of cables in terms of reach and coexistence with other transmission technologies in the cable. By means of repeaters the already extended reach in comparison with ADSL can be almost doubled. Thus EMX is a simple solution to leverage fast increase of Broadband - Internet and telephony penetration!

• Connect more POTS subscribers over one copper pair in access network
• Connect more POTS & Broadband-Internet subscribers over one copper pair in access network
• Solve problem of connecting distant Broadband Internet subscribers, which ADSL can not reach
• Solve the problem of interferences of different transmission technologies in the same cable
• Replace ADSL blocker technologies, like narrow band pair gain systems (PGS) or twins, and Provide Broadband Internet Access to all customers
• Provide total POTS & Broadband-Internet solution for SOHO customers over single copper pair
• Simply economize the existing copper infrastructure for mass Broadband Internet Access deployment
