RAD moves into carrier-class technology

RAD's Pseudowire Gateway Delivers 'Carrier-Class' lease-line replacement technology over IP/Ethernet/MPLS Networks.

In a move which takes its lease-line replacement technology beyond corporate to carrier-class, RAD Data Communications has released the second phase of its IPmux-14 TDM pseudowire gateway.

Using RAD's TDM over IP (TDMoIP) technology for transparent voice and data, the IPmux-14 version 2 enables carriers, service providers and businesses to reduce operating expenses by delivering TDM, data and LAN services over IP/Ethernet/MPLS networks.

The solution offers TDM-based voice, fax, modem, and data services without compromising traditional telephone network quality.

For customers that want to connect offices or remote workers, the Ipmux-14 eases the migration path to internet-based networks by offering both voice and data services over a single, unified, packet-based infrastructure.

It allows providers to cut costs and increase revenues, while preserving business customers' investments in existing telephone equipment.

Telephony and private line/leased line traffic is conventionally carried over connection-oriented synchronous or plesiochronous networks (loosely referred to as TDM networks).

With the proliferation of internet-based networks, there is a need to integrate TDM services into a unified packet switched network (PSN) infrastructure.

This integration requires emulation of TDM circuits within the PSN, a function that can be carried out using pseudowire technology.

This emulation delivers quality of service and voice similar to those of existing TDM networks, and also preserves signalling features.

"As the reliance on the Internet grows, the IPmux-14 plays a important role in reducing the cost burden of all parties by delivering virtually all TDM, data and LAN services over IP/Ethernet/MPLS networks".

"What's more, it addresses issues with voice quality over the Internet by maintaining priority for the voice traffic over the network link," said Grant Notman, UK general manager at RAD Data Communications.

"It's a win-win situation for all".

"The end user benefits as they continue to receive all their familiar services, while carriers and service providers can continue to maintain revenues from legacy services," he explains.

"Both carriers and enterprises will benefit from its compact size, ease of installation and support for multiple legacy and next generation Ethernet and IP-based services".

With a highly advanced clock recovery, the IPmux-14/A can provide high quality TDM pseudowire with 16 ppb clock accuracy while maintaining strict jitter and wander standards compliant with a G.823 synchronisation interface.

"This capability is ideal for deployment in cellular backhaul networks," adds Notman.
