A multi-drop in-house ADSL distribution network

In this paper, we propose an all digital, multi-drop in-house asymmetric digital subscriber line (ADSL) distribution network, utilizing the existing wiring on customer premises. The proposed in-house network is based on a simple quadrature phase-shift keyed (QPSK) signaling format with frequency diversity. The network signal resides between approximately 1.5 MHz to 20 MHz of the frequency band and will not interfere with existing POTS and ADSL signals. The proposed in-house ADSL network will allow multiple users in the same household to share a single, high speed (6+ Mbps) ADSL line with only one ADSL remote transceiver unit plus a number of inexpensive service modules. This flexible, cost-effective solution will, therefore, eliminate the need for expensive internal rewiring or wireless distribution of ADSL signal to service multiple users in the same household
