Mappers upgrade Ethernet over Sonet
Second generation Ethernet over Sonet/SDH framers are targeted at carrier grade packet transport networks enabling advanced Ethernet services to businesses and residential triple-play services.
Service providers are migrating their radio based access network from copper facilities carrying DS1/E1 to fibre facilities utilising Sonet/SDH signals to deliver richer packet services to their cellular customers.
An efficient method of transporting a mix of Ethernet and TDM traffic between cell sites and basestation controllers is required for a smooth transition from ATM over DS1/E1 connectivity to Ethernet over Sonet/SDH connectivity in the radio access network.
Radio transmission products that primarily provided DS1/E1 or DS3/E3 transport over radio links are now being required to support the proliferation of Ethernet interfaces on today's network equipment to increase bandwidth capacity and add support for Ethernet services.

Compact and fast dual gigabit Ethernet
Advantech, industrial computer manufacturer and automation innovator, releases its PICMG-3.1-compliant PCI Mezzanine Card (PMC), the MIC-3665.
Next generation Sonet/SDH features such as the Generic Framing Procedure (GFP), Virtual Concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS) are ideal for multiplexing TDM and Ethernet traffic for transmission over radio links.
Sonet/SDH capable radio transmission products inherit all of the carrier grade attributes of Sonet/SDH such as reliability, performance monitoring and secure remote management while providing the capability to mix radio and wireline segments to form a Sonet/SDH ring network.
"New packet-based services are placing higher bandwidth demands on cellular backhaul networks and radio transmission links", said Richard Deboer, CEO, Galazar Networks.
"The world is migrating to Ethernet interfaces and the ability to transport Ethernet simultaneously with existing TDM signals is critical to the migration of the transport network infrastructure required to support new services".
The unique combination of Fast Ethernet, Gigabit Ethernet, DS1/E1 and DS3/E3 client interfaces make RadioNode ideally suited to providing efficient multiplexing of the variety of signal formats in today's radio access networks.
Inherent support for low order UPSR/SNCP rings allows efficient sharing of bandwidth and minimises ports at the radio network controller (RNC) and the basestation controller (BSC) when aggregating traffic from multiple cell sites.
Support for up to 28 DS1/E1 ports and eight Ethernet ports allows for continued growth of the existing DS1/E1 infrastructure while supporting the transition to Ethernet capable cell station equipment.
Sonet/SDH fibre infrastructure in the radio access network also provides increased immunity to costly service interruptions caused by tower lightning strikes.
In radio transmission applications, RadioNode's 0:2 Sonet/SDH interface protection used in conjunction with VCAT and LCAS allows Ethernet traffic to be split over two diverse links providing resiliency to radio link interruptions and effectively doubles the contiguous transmission capacity to 311Mbit/s.
Building on Galazar's reputation of delivering more than just devices with rudimentary software, its colocated team of experienced IC, hardware, software and system designers minimise customer time to market by working together to define, develop, verify and support these solutions as end-to-end systems.
Through proprietary tools and processes we are able to provide extensive software, documentation, troubleshooting tools, reference platforms and application design information to customers.
Galazar offers comprehensive device management software, including advanced capabilities such warm start, interrupt management and a wide variety of troubleshooting tools that are field proven by customer deployments.
RadioNode and associated software is available now.
