Most of us have started exceeding the bandwidth offered by xDSL/E1/T1 circuits and to top it all we now need "triple play" of services i.e. combined voice, video and data traffic over the same link. Thanks to distance learning the internet is our classroom and time and distance are non issues. With Telemedicine quality healthcare is available right in your home town as you ge

Are IP 67 PoE Ethernet Extenders the Answer for Industrial Connectivity? Originally published in  automation.com By Brad (Biju) Oommen, Networking Solutions Consultant With rapid digitization, Power Over Ethernet (PoE) Ethernet extenders can greatly benefit PoE enabled network devices such as: Radio Frequency Identification (RFID) readers, IP Paging systems, IP cameras, IP phones, IP Horn Speakers, Sensors and Wireless access points. This can be especially true in hard to reach outdoor locations in factory environments and industrial settings. System installers and planners, for such solutions and systems, can avoid running multiple cables dedicated to main AC power and network connectivity. Thus, they can avoid costly installation and maintenance, especially when they are far away from AC power outlets and beyond the reach of wired Ethernet network connections. PoE Ethernet extenders can play a vital role in delivering power and data over var

Addressing the Limitations of Ethernet and PoE

Addressing the Limitations of Ethernet and PoE  By  Biju Oommen Originally published in  Cable Technology Feature Article First standardized in 1983 as IEEE ( News  -  Alert ) 802.3 today’s Ethernet technology with its several variations, is ubiquitous as the de facto transport technology for IP networking. The technology has been continuously developed and enhanced over the decades since its initial implementations. Among the latest expansions is the capability to transmit electrical power over the network cabling along with the data. To date, Power-over-Ethernet (PoE) technology has vastly expanded the kinds of applications that system integrators and installers can support. Many more are expected to emerge Yet the technology does have some pesky limitations:  namely distance, cable type, and available power at remote stations. 1)Distance A standard Ethernet segment is limited to 328 feet (100 meters) in length over standard-gauge CAT5 cable. That restricted reach c

eSBCs: Required for Secure, Interoperable Real Time Unified Communications

By Biju (Brad) Oommen Originally published in  Communications Applications News Session refers to the RTC session between two endpoints.In the Digital Age, as a part of the digital transformation for unified communications (UC), organizations worldwide are retiring legacy ISDN/TDM primary rate interface (PRI) voice systems. They are replacing it with Session Initiation Protocol (SIP) based voice and real-time-communications (RTC) services. Whether you are an Over the Top (OTT) provider of SIP trunking or an Internet Telephony Service Provider (ITSP)—or even a subscriber— the enterprise session border controller (eSBC) is a multi-function platform that can provide valuable services for SIP interconnections (real-time communications). The acronym SBC breaks down as follows: Border refers to the crossing point between two networks with disparate trust levels: e.g. your enterprise network and the service-provider network. Controller refers to the ability of the platform to control th
