New applications and increasing inter-office traffic are drivers for change in data and voice convergence according to network access equipment manufacturer, RAD Data Communications.
Its recent launch of new compact interface converters has been designed for carriers still relying on extensive deployment of SDH/SONET rings to transport traffic, as well as users wanting wide area networking out of LAN services.
Billed as carrier-class solutions for transporting Ethernet over fractional E1, E1/T1 or xE1/T1, RAD has positioned the two converters as alternatives for ISPs and carrier backhaul applications, or for carriers seeking new ways to provide high bandwidth Ethernet services to customers.
The RIC-155 GE, a Gigabit Ethernet-over-STM-1 gateway, is designed to deliver Gigabit Ethernet traffic over SDH and PDH networks. The RIC-155A has two Fast Ethernet ports to convert two different flows of Fast Ethernet traffic over an STM-1 link.
The carrier space has a mixture of PDH, SDH and ATM transport networks and lately introduced IP technologies, so the question of how to converge data and voice whilst still being compatible still provides opportunities according to RAD Australia general manager, Udi Furman.
“SMEs had and still have separate lines for data and voice and the introduction of VoIP technology gave a great push for convergence,” he said. ““When VoIP was introduced in 2000, it still wasn’t ready as a carrier-class service, so a stop gap market was created.”
With the increasing presence of IP, and specifically VoIP, Furman said the two new products were not stop gap solutions for increasingly redundant technology.
“Convergence of data and voice has always been an issue,” he said.
