Preface This white paper analyzes several methods of connecting a Digital Subscriber Line Access Multiplexer (DSLAM; and splitter) to the outside plant. Analyzed methods include dedicated pair count, protected jumper, wire-wrap management cabinet and the KRONE Asymmetric Digital Subscriber Line (ADSL) delivery solution. The analysis primarily focuses on remote equipment deployments serving lines provisioned on pair-gain or Digital Loop Carrier (DLC) systems. General ADSL has emerged as the broadband access technology of choice for most telephony providers throughout the world. While the initial deployment of DSLAMs rushed to keep pace with burgeoning customer demand, current conditions require greater consideration of regulatory and economic factors. Increased scrutiny mandates no less than optimal deployment of capital spending. In contrast to dial-tone, DSL is not ubiquitously available. While the location of DSLAM deployment is critical, the efficiency of the equipment’s interface with the outside plant is paramount. Slight idiosyncrasies in this interface can result in substantial service interruptions (both voice and data), underutilization of the DSLAM and dramatic increases in operating expenses. ADSL service is unique in that it can be deployed on the existing cable pair, sharing the line with voice dial-tone. While this equates to cost savings for the operating company and subscriber, it also comes with some deployment issues. The customer’s dial-tone must be interrupted and then re-routed through the DSL equipment to be combined with the data. The combined voice and data must then be connected back to the cable pair. .
