This contribution proposes for Recommendation G.812 (1) a holdover specification for Clock Type II that is consistent with the current specification of 10 per day and is not broken into aging, temperature, and initial offset components and (2) a modification to the output wander TDEV mask, to apply only to Types II and III, to make the mask consistent with the respective wander generation TDEV ...

1 Loss System For a background review, I started the summer vacation scholorship by looking at loss systems. In a telecommunication context, this means that a new coming call is blocked (or lost) if there is no free circuits for that call. First of all, I made myself familiar with the notations. In a loss system, let C be the total number of circuits available, n be the number of circuits in us...

Telecommunication Networking

Toady’s telecommunication network serves as an essential platform in our society for exchange of information in its various possible forms, viz., voice, data and video, and thus helps us in living the life of this modern era. Networking practices have evolved almost over two centuries with an unbelievable range of technologies, services and standards, calling for accommodation of heterogeneous ...

We define a family of high-rate binary LDPC codes for ADSL. We present simulation results that show the performance that can be achieved by these codes on a binary additive white Gaussian noise (AWGN) channel. LDPC codes exhibit performance very close to the capacity limit with moderate decoding complexity and are thus well suited for channel coding applications in ADSL systems.
