TDM pseudowire gateway promises to maximize transport operators' investments in fiber rollouts
RAD Data Communications, a specialist in pseudowire technology, has announced the launch of a new TDM pseudowire access gateway that is designed to enable transport operators to maximize return on investment from their fiber rollouts.
"The IPmux-216 TDM pseudowire access gateway justifies the cost of fiber build-outs because it allows transport operators to offer multiple E1s or T1s with the highest degree of timing accuracy on the market," explains Eyal Gabay, Senior Product Line Manager at RAD Data Communications. "RAD engineered into its ASIC two crucial assets that the competition can't offer - guaranteed accurate timing and support for multiple clock domains over Ethernet," Gabay continues. "This allows transport providers to utilize their fiber by backhauling mobile traffic simultaneously from different cellular operators, with each one being able to rely on its own clock to guarantee synchronization - in the past, a sore point for pseudowire circuits, but with careful forethought and engineering RAD has met the challenge."
The heart of the IPmux-216 is said to be a 'unique' multi-standard pseudowire ASIC processor, developed in-house by RAD, that supports a full range of pseudowire flavors, including TDMoIP (RFC5087), CESoPSN (RFC5086), SAToP (RFC4553), and HDLCoPSN (RFC4618). Pseudowire technology is typically used to extend E1/T1 and DS3 services transparently over IP, Ethernet and MPLS networks.
The IPmux-216 enables transport operators to support multiple customers and multiple timing domains with a single pseudowire device while maintaining stringent timing distribution and clock recovery mechanisms on a per-E1/T1 basis. With this critical capability, transport operators can ensure that they profitably utilize the IPmux-216's full throughput and provisioning capacity, regardless of whether it is servicing a single customer or multiple customers.
Mobile operators and retail carriers require that transport providers, such as cable MSOs deliver E1/T1 circuits over their packet switched networks. These wholesale services must be comparable to traditional E1/T1s, including support for in-band facility loopbacks, fault propagation and other Operations, Administration and Maintenance (OAM) tools. The IPmux-216 provides these capabilities and is, therefore, ideal for wholesale E1/T1 services for mobile backhaul and Multi-Tenant Units (MTUs).
RAD's IPmux-216 converts up to 16 E1/T1 TDM data streams into packets for transport over Ethernet, IP and MPLS networks. It also offers SFP-based fiber or copper Ethernet interfaces that support Fast Ethernet and Gigabit Ethernet. The IPmux-216 pseudowire gateway supports a wide range of management, networking and security-related protocols, including RADIUS, SSH/SSL and SNMPv3.
