The purpose of this document is to define a framework for an Access Node Control Mechanism between a Network Access Server (NAS) and an Access Node (e.g. a Digital Subscriber Line Access Multiplexer (DSLAM)) in a multi-service reference architecture in order to perform QoS-related, service-related and Subscriber-related operations. The Access Node Control Mechanism will ensure that the transmis...

The purpose of this document is to define a framework for an Access Node Control Mechanism between a Network Access Server (NAS) and an Access Node (e.g., a Digital Subscriber Line Access Multiplexer (DSLAM)) in a multi-service reference architecture in order to perform operations related to service, quality of service, and subscribers. The Access Node Control Mechanism will ensure that the tra...

This paper describes how one can reduce the memory access time with pre-emphasis (PE) pulses even in non-volatile random-access memory. Optimum PE pulse widths and resultant minimum word-line (WL) delay times are investigated as a function of column address. The impact process variation constant WL, cell current, resistance deciding path on optimum discussed. WL modeled fitting curves address a...

The Korean telecommunications services market has recently experienced an unprecedented growth in the wire-line broadband Internet access and mobile telephony markets. At 2004, 11 million households had broadband Internet access, while mobile telephony subscription reached 36 million—the corresponding penetration rates are 73% and 75%, respectively. By contrast, wire-line and wireless voice mar...

Byungjoo Park et al. 301 As broadband access is evolving from digital subscriber lines to optical access networks, Ethernet passive optical networks (EPONs) are considered a promising solution for next generation broadband access. The point-tomultipoint topology of EPONs requires a time-division multiple access MAC protocol for upstream transmission. In this paper, we propose a new enhanced dyn...
