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. 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 Inc. "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 minimizes ports at the Radio Network Controller (RNC) and the Base Station Controller (BSC) when aggregating traffic from multiple cell sites. Support for up to 28 DS1/E1 ports and 8 Ethernet ports allows for continued growth of the existing DS1/E1 infrastructure while supporting the transition to Ethernet capable cell station equipment. SONET/SDH fiber 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 311 Mbps.
