RAD Releases v.2 of Its IPmux-14 TDM Pseudowire Gateway

RAD Data Communications has released version 2 of its IPmux-14 TDM pseudowire gateway, which supplies Ethernet, TDM and HDLC-based services over packet switched networks (PSNs). HDLC-based services include Frame Relay, X.25 and transparent PPP transmission.

Using RAD's patented TDM over IP (TDMoIP) technology for transparent voice and data, the IPmux-14 TDM pseudowire gateway enables carriers and service providers to take advantage of the new IP/Ethernet/MPLS networks to deliver TDM-based voice, fax, modem, and data services without compromising traditional PSTN quality. HDLC pseudowires support HDLC-based data with bandwidth optimization by suppressing HDLC idle flags.

The IPmux-14 TDM pseudowire gateway converts TDM user traffic data streams from four E1/T1 ports or a serial port into IP packets or MPLS frames for transmission over the PSN via a Fast Ethernet uplink, either UTP or fiber. Another TDM pseudowire gateway at the remote side converts the packets back to TDM traffic. A low port density version, the IPmux-14/2, offers two E1/T1 ports instead of four.

The IPmux-14 TDM pseudowire gateway offers extended, Layer 2-based, TDM and Ethernet integrated access capabilities. The product enables wire-speed bridging between the user LAN and the Ethernet WAN. User LAN traffic can be rate limited, tagged and filtered (based on VLAN membership) and double VLAN tagging (VLAN stacking) can be applied to better engineer the network and allow a granular bandwidth capacity offering.

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