RAD Introduces Two New Pseudowire Gateways
Ideal for Co-Location of 2G and 3G Mobile Backhaul and Carrier Migration of Legacy Services to PSNs
February 28, 2012
RAD Data Communications, the industry pioneer of pseudowire technology, has introduced two new TDM pseudowire gateways that are ideal
for facilitating economical PSTN access and TDM trunking over wired and radio packet access.
IPmux-4LGE are ideal
for colocation of 2G and 3G mobile backhaul because they enable TDM 2G traffic to be
transported over 3G’s packet infrastructure,” explains Ido Miran, IPmux Product Line Manager at RAD Data Communications.
“Co-location drastically reduces mobile operator CapEx and OpEx by eliminating the need to maintain two simultaneous backhaul
In addition, the pseudowire-empowered IPmux-16L and IPmux-4LGE facilitate carrier migration of legacy services, such as PSTN
access and E1 leased lines for corporate PBX connectivity, from legacy transport infrastructure to IP, Ethernet and MPLS packet
switched networks (PSNs). Enterprises and public utilities can similarly deploy the IPmux solution on top of their private IP/Ethernet
networks or leased VPN connections, for transporting their inter-site TDM voice and data traffic without replacing their existing
legacy equipment or affecting service quality.
“These two new IPmux solutions complement RAD’s existing pseudowire gateways that already have been integrated by Tier 1 carriers
into their network architecture,” Miran states.
Hardware-Powered Pseudowire Engine for Enhanced Performance
Incorporating RAD’s new generation of ASIC processors, the IPmux-16L and IPmux-4LGE feature enhanced pseudowire performance with
minimal processing delay and Ethernet ring protection with sub-50 msec switchover. They can connect over a standard Ethernet fiber ring,
as well as in hub-and-spoke and point-to-point topologies.
The IPmux-16L comes equipped with eight or 16 E1 user ports and on the other side three Fast Ethernet and three Gigabit Ethernet ports.
The IPmux-4LGE is equipped with four E1 user ports, four Fast Ethernet ports and either one or three Gigabit Ethernet ports.
All Fast and Gigabit Ethernet ports on these two versatile products can serve either the user or the network.
The IPmux-16L and IPmux-4LGE support various clocking options to ensure synchronization as any standard TDM device.
They can also recover the original clock with great accuracy, using per-port adaptive clock recovery.
Founded in 1981, RAD Data Communications has achieved international recognition as a major manufacturer of high quality access
and backhaul equipment for data communications and telecommunications applications.
The company's installed base exceeds 12,000,000 units and includes more than 150 carriers and operators around the world,
including AT&T, China Mobile, Deutsche Telekom, France Telecom/Orange, Hutchison, KDDI, Telekom Austria, TeliaSonera, Telstra,
T-Mobile, Verizon, and Vodafone.
RAD is an active participant in industry organizations such as the IETF, Broadband Forum, ITU, and MEF.
