چکیده
In a SONET/SDH network the frame alignment is an important function. This paper presents a component that realizes it and the section layer functionality in a SONET/SDH network. The user can choose between STS-1/STM-0 at 51.48 Mbps or STS-3/STM-1 at 154.44 Mbps operation. There are some components to do frame alignment [1] but here we present a new component with a wider range of functions. The proposed circuit consists of a parallel descrambler, a section alarms indicator and section BIP-8 byte calculator. We introduce all these functions in only one component. This framer can be part of any network element (NE) with section layer function. Moreover, it works with byte flow instead of bit flow. This component can be reused for construction of a framer at higher transmission rate.

In this paper we present the ASIC implementation of STM-1 Framer and De-Framer. This paper mainly focuses on multiplexing digital data, transmitting and receiving the STM-1 frame. The design is implemented using Verilog HDL, simulated on Modelsim and Synthesized on Xilinx ISE 13.2. For power analysis and area calculation, the designed framer and de-framer are analysed using Cadence version 6.1....

We explore the benefits of virtual concatenation in SONET/SDH-based traffic-groomable mesh networks. Our results qualitatively and quantitively demonstrate that virtual concatenation can improve bandwidth efficiency, simplify network control, and balance network load. 1. Background Optical SONET/SDH networks are the dominant infrastructure to support data and voice traffic in backbone and metro...
