Abstract

A Digital Subscriber Line Multiplexer (DSLAM) is an access box that provides xDSL (ADSL, ADSL+, ADSL2+, SHDSL and/or VDSL) broadband and voice services to subscribers via metallic lines. A Next-Generation Digital Loop Carrier (NGDLC) or Broadband Loop Carrier (BLC) is an access box that provides Plain Old Telephone Service (POTS), lease-lines and xDSL services to subscribers. DSLAM or NGDLC access boxes can be installed in the center of high-density urban areas. Besides providing xDSL to business customers via metallic lines it is proposed to equip these boxes with additional Wi-Fi (Wireless-Fidelity, i.e. IEEE WLAN 802.11, etc.) features (Fig. 1). With this feature the services can be accessed wirelessly (PDA, Smartphone, notebooks, etc.) by the customers. - The Wi-Fi circuit pack and antenna can be fully integrated within the access box. Optionally an external antenna can be used to enlarge the area of service. - Wi-Fi security can be enabled to allow access to subscribers only. - The access box can provide the wired and the wireless service simultaneously. An Optical Line Terminal (OLT) in an Optical Access Network (OAN) provides the network-side interface to the OAN and is connected to one or more Optical Distribution Networks (ODN). An Optical Network Unit (ONU) provides the user-side interface of the OAN and is connected to the ODN. An Optical Network Terminal (ONT) is an ONU used for Fiber-To-The-Home (FTTH) application that includes user-port functions. An OAN provides both: broadband and narrowband services to residential and business subscribers.
