{{>toc}} h1. Siemens FastLink FastLink is a family of devices forming a (primarily) [[PDH]] transport network technology by Siemens. It serves the following functionalities: * transport of (leased) digital subscriber lines (typically 2 Mbps) over copper (1-pair G.SHDSL, 2-pair HDSL) and fiber (UG2 or proprietary single-fiber bi-directional system) * add/drop multiplex of digital subscriber lines, e.g. from E1 (2 Mbps) to E3 (34 Mbps) * optionally, add/drop multiplex up to STM-1 (electrical or optical) * optionally, subscriber line termination of (leased or switched) POTS + ISDN lines ([[V5_Access_Multiplexers]]) * optionally, cross-connect functionality FastLink would typically be deployed as a _transport network_ by a telecom operator around the year 2000. They would deploy a number of multiplexers at various points of presence, from where they would run HDSL, HSDSL or optical lines to the respective customers that subscribed to a variety of digital services. Between the points of presence there would typically be a ring, either at the E3 or (probably more often) at the STM-1 level within the digital hierarchy. h2.
