RAD Introduces Next Gen Pseudowire Gateway for Cellular Backhaul Transport Providers

March 27, 2007: RAD Data Communications, the telecommunications industry pioneer of pseudowire technology, has announced that it will unveil its feature rich, IPmux-116 pseudowire gateway at CTIA 2007, to be held March 27-29 in Orlando, Florida.

"The IPmux-116 is the next generation in pseudowire access solutions," states Eitan Schwartz, Vice President of Pseudowire and Carrier Ethernet at RAD Data Communications, Inc. "What makes it unique is that it combines high-performance ASIC technology with a comprehensive feature set optimized for the transport providers. This includes accurate regeneration of timing on a per port basis to support multiple customers' timing needs, in-band facility loopbacks to allow customers to test their circuits independently of the transport provider and VLAN-aware switching with ingress and egress rate limiting to provide tunable bandwidth. Also important to note is that the IPmux-116 is the only pseudowire gateway capable of supporting all modes of TDM emulation, including SAToP, TDMoIP, CESoPSN and HDLCoPSN," he explains.

The flexibility of the IPmux-116 helps the cellular backhaul transport providers meet the specific needs of mobile operators. Because these providers host multiple operators at each tower, they must be able to simultaneously support each operator's chosen backhaul technology - from delay sensitive CDMA to timing sensitive GSM and UMTS. RAD's ASIC , however, also enables the IPmux-116 to transport backhaul traffic over IP, Ethernet or MPLS networks using any of the standard TDM emulation technologies," Schwartz states.

Delivering carrier-class TDM services requires sophisticated clock recovery technology. RAD has solved this problem by incorporating into its ASIC an advanced adaptive clock recovery mechanism. This mechanism conforms to the G.823 sync interface using G.8261-defined scenarios and achieves 16 ppb clock accuracy. Clock redundancy can be achieved through a system-timing feature that uses master and fallback timing sources. Furthermore, timing can be input or output to external peripherals through an optional external clock port. RAD's timing solution not only supports each operator's separate clocking requirements, but can also lock each operator's ports to their BSC/MSC timing source. "The IPmux-116 is truly a one-box solution for the transport provider to service multiple operators," Schwartz concludes.

RAD's compact, 1U-high IPmux-116 can be ordered with eight or sixteen pseudowire ports, one or two Ethernet network ports and one or two Ethernet user ports to meet the specific demands of each transport provider and the requirements of each site. It is fully manageable and offers a full suite of OAM capabilities. The product is also equipped with a redundant AC/DC power supply.
