Cable Television Laboratories Inc., and its associates have prepared a series of interface specifications known Data over Cable System (DOCSIS) that permit the early definition, design, development and deployment of data-over-cable systems on a uniform, consistent, open, non-proprietary, multi-vendor interoperable basis. This would also back up the cable operators are interested in deploying high-speed data communications systems on cable television systems.

This service allows transparent bi-directional transfer of Internet Protocol (IP) tr ....etc

Local Area Networks are now being used to transport voice and video traffic together with traditional data traffic that they have already supported. And in the case of voice and video applications, not only is these is a need for more bandwidth, but there is also a need for guaranteed levels of receive because these applications are very sensitive to latency and delay.
Inverse multiplexing can be proved as technology that overcomes the bandwidth gap that exists between LAN and WAN. Inverse multiplexing is exactly the opposite of traditional m ....etc

Power over Ethernet (PoE) is a revolutionary technology that extends the already ultra-broad functionality of Ethernet by supplying reliable DC power over the same twisted-pair cable that currently carries Ethernet data.

PoE, modeled after the technology used by the telecommunications industry to supply reliable power to telephones, enables lifeline quality power for IP telephones (VoIP) as well as many other low power Ethernet network devices like wireless access points (WAP) and security cameras.

When locating access points, system des ....etc

ABSTRACT

With internet use continuing to explode, with an increasing number of users switching to IP- based networks, and with data traffic about to surpass voice traffic, network service providers have looking for a faster; more efficient, and less expensive transport technology to handle the heavy volumes of traffic they are experiencing.
With this in mind, many providers have de ....etc

This paper seeks to present ways to eliminate the inherent quantization noise component in digital communications, instead of conventionally making it minimal. It deals with a new concept of signaling called the Signal Code Modulation (SCM) Technique. The primary analog signal is represented by: a sample which is quantized and encoded digitally, and an analog component, which is a function of the quantization component of the digital sample. The advantages of such a system are two sided offering advantages of both analog and digital signaling. ....etc

Abstract


With internet use continuing to explode, with an increasing number of users switching to IP- based networks, and with data traffic about to surpass voice traffic, network service providers have looking for a faster; more efficient, and less expensive transport technology to handle the heavy volumes of traffic they are experiencing.
With this in mind, many providers have decided to carry IP traffic, directly over SONET (synchronous optical network), rather than via frame relay, ATM backbones, or leased lines.
The explosive growt ....etc
