Large-Scale Integration of Hybrid-Method Digital Subscriber Loops
This paper reports on studies concerning the feasibility of large-scale integrated realization of the circuits needed to provide hybrid-mode full-duplex digital transmission at 80 kbits/s or higher rates over standard local telephone loops. Alternative means of achieving the required 60 dB or so of echo cancellation have been studied in detail. The conclusion is that a combination of analog and...
متن کاملTiming Recovery in Digital Subscriber Loops
Tradeoffs in the design of the timing recovery functions in a subscriber loop receiver are analyzed. The techniques considered are applicable to both the echo cancellation (EC) and time compression multiplexing (TCM) methods of full duplex transmission. Emphasis is on those techniques that lend themselves to implementation in MOSLSI technology, where the objective requirement is that timing rec...
متن کاملTiming Recovery in Digital Subscriber Loops Using Baud-Rate Sampling
Sampled-data techniques are the most practical means of obtaining the necessary signal ,processing functions for timing recovery in the VLSI implementation of a digital subscriber loop transceiver. The sampled-data timing recovery techniques described in this paper are applicable to both echo .cancellation-and time-compression multi-plexing systems. Timing recovery using baud-rate sampling in c...
متن کاملA Planning Method for Integration of Large-scale Engineering Systems
Complex products and large engineering systems require massive efforts to integrate designs at various levels: product and production plans into components, components into sub-systems, sub-systems into systems, and systems into a quality product. We define the product development integration problem as the challenge to coordinate the engineering activities at each level in order to achieve an ...
متن کاملTheoretical and practical limits of next-generation high-speed digital subscriber loops
For the single-pair HDSL (HDSL2), the concept of having different upstream and downstream power spectral densities is highlighted. The signal-to-noise ratio (SNR) at the input of the central office HDSL terminal unit (HTU-C) can be enhanced by boosting the power output of the remote user HDSL terminal unit (HTU-R). Further improvement in performance can be achieved by reducing the HTU-C NEXT in...
