CAT previously used an analog phone system that had high maintenance costs. They wanted to enable communication across phones, mobiles, and PCs while reducing costs. AIT designed a solution using Cisco's Unified Communication System which allowed CAT to transition to an IP telephony system running on their IP network. This provided the same features from any device connected to the IP network, reducing costs for maintenance and adding new phones.

WI-TEK FTTX POE SOLUTION
The document describes Wi-Tek's FTTx PoE switch solution for ISPs. The switch can be powered remotely using power from a customer's location via a Wi-Tek PoE router or injector. This eliminates the need for on-site power and saves money for ISPs. The switch then provides power to other network devices like ONUs using PoE output ports. This provides a cheap way for ISPs to build fiber networks and deliver uninterrupted internet service to customers without incurring power costs.
WI-TEK POE SOLUTION FOR CCTV
Power over Ethernet (PoE) allows network cables to carry electrical power to devices like IP cameras and wireless access points. It simplifies installation by providing power and network access over a single cable. PoE works by using spare wire pairs in Ethernet cables to transmit power to compatible devices from a PoE switch or injector. This allows devices to be placed anywhere within the cable's transmission distance without needing separate power cables. Wi-Tek produces PoE switches that can transmit power up to 250 meters, allowing more flexibility in camera placement.

What is PoE?
Power over Ethernet (PoE) is a networking feature that lets network cables carry electrical power over an existing data connection with a single Cat5e/Cat6 ethernet cable. PoE technology relies on the IEEE 802.3af and 802.3at standards, which are set by the Institute of Electrical and Electronics Engineers and govern how networking equipment should operate in order to promote interoperability between devices.

The document discusses how Phybridge PoLRE switches can help organizations eliminate infrastructure barriers to migrating to IP telephony. The switches leverage existing copper wiring to provide power and Ethernet connectivity over long distances, allowing organizations to deploy IP phones without needing to upgrade cabling or add new network switches. This provides significant cost savings compared to traditional IP migration approaches. The switches create a robust and secure IP network that supports not only IP phones but also additional applications like security cameras and wireless access points. Several case studies show how large organizations successfully used Phybridge switches to migrate thousands of users to IP with minimal disruption and costs.

Why Not Choose a PoE Switch?
The Power over Ethernet (PoE) lets Ethernet cables supply the power for network devices, at the
same time as transmitting data in the normal way. Typical PoE users are businesses adding to their
network or adding VoIP phones in buildings where new power lines would be expensive or
inconvenient. So why not choose a PoE switch? PoE switches give you an easy way to add PoE
devices to your network. The plug-and-play switches will automatically detect whether connected
devices are PoE or PoE+ and send power accordingly.

A Quick Look at the PoE Switch
When installing a network, one of the first things users consider is whether to use fiber optic cable or copper cable. Although both copper cable and fiber optic cable can transmit an acceptable signal, fiber optic cable is the most desired choice with today’s growing bandwidth requirements over long distances. This article will share eight reasons why users should choose fiber optic cable over copper cable.

Fiber optics based schemes modeling and simulation of QoS for Wi-Fi scenario...
Wireless Fidelity (Wi-Fi) network is created on the IEEE 802.11 standard. Connections for local devices in homes and business arenas are provided by Wi-Fi units. With the growing demand as well as penetration of wireless services, the wireless networks users now assume Quality of Service (QoS) besides performances comparable to what is accessible from secure networks. In this paper, OPNET Modeler is used as module and for the simulation of a fiber optic-based Wi-Fi network within a fixed local area network. The aim of this paper is to evaluate their Quality of service (QoS) performances in terms of Wi-Fi voice-packet delay and End-to-End for both Wi-Fi base fiber and Wi-Fi base line. Many scenarios, with same Physical and MAC parameters, have many subnet networks are implementing with fiber optics baseline in addition to Wi-Fi baseline, were created in the network OPNET simulation tool for obtaining the results. The results of simulation reveal that base line demonstrated more delay than base fiber.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

High performance Serverless Java on AWS- GoTo Amsterdam 2024
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
