Product SummaryRAD's IPmux-8 TDM pseudowire access gateway and IPmux-16 TDM pseudowire access gateway are modular, carrier class solutions, using TDMoIP technology to deliver E1/T1, E3/T3 or channelized T3 services over IP, Ethernet and MPLS networks. Located at multi-tenant office buildings, regional POPs and central service POPs, the IPmux-8 and IPmux-16 TDM pseudowire access gateways aggregate TDMoIP traffic from multiple sources. The IPmux-8 TDM pseudowire access gateway and IPmux-16 TDM pseudowire access gateway conform to pseudowire circuit emulation standards defined by the IETF PWE3, ITU-T and MFA Forum. Benefits• Enable a smooth migration to PSNs• Allow carriers to benefit from packet-transport's scalability and cost-effectiveness while maintaining legacy services' performance requirements• Reduce OpEx by minimizing the number of E1/T1, E3/T3 leased lines• Support standard TDMoIP pseudowire technology o Reduce CapEx with scalable, modular design for economical system changes and upgrades Further Product InformationThe IPmux-8 and IPmux-16 TDM pseudowire access gateways convert TDM user traffic data streams into IP packets or frames, for transmission over packet-switched networks (PSNs) via Fast Ethernet uplinks. A TDMoIP gateway at the other end converts the packets back to TDM traffic. These gateways take advantage of packet transport's capacity, flexibility and low-cost, to deliver legacy TDM-based voice and data services without compromising traditional PSTN quality. The IPmux-8 and IPmux-16 employ standard pseudowire emulation edge-to-edge (PWE3) technology, defined by the IETF, ITU-T and MFA Forum. Integrated accessIPmux-8 and IPmux-16 enable economical transport of voice, video and data traffic over PSNs. Offering transparent E1/T1 and E3/T3/CT3 connectivity over Layer 2 and Layer 3 packet networks, they support point-to-point and point-to-multipoint applications in carrier and enterprise environments. User port traffic can be rate-limited, tagged and filtered (based on VLAN classification), while double VLAN tagging (VLAN stacking) can be applied to better engineer the network and allow a granular bandwidth offering. TDM circuit extensionIPmux-8 and IPmux-16 support the following features:• E1/T1 connectivity for any user device with standard E1/T1 interface• Alarm detection with error statistics• SES/UAS statistics, LOS/AIS physical layer alarms and remote/Local Loop test modes In addition, both devices support standard E1/T1 alarms from end to end. Modular designIPmux-16 and IPmux-8 are modular, carrier-class TDMoIP gateways. IPmux-16 is also NEBS-compliant (by special ordering). • E1 and T1 modulesThe IPmux-16 pseudowire gateway supports up to two E1 or T1 modules, including four or eight ports each, for a maximum of 16 E1/T1 channels. The IPmux-8 pseudowire gateway supports up to two E1 or T1 modules with four ports each. • Ethernet modulesIPmux-16 and IPmux-8 incorporate up to two Ethernet modules. Each module provides one or four Fast Ethernet ports with 10/100BaseT, or up to 2 SFP-based ports. Redundancy and load sharing between Ethernet uplinks are thus supported. • E3 and T3 modulesTwo unframed E3 or T3 modules can operate in a single IPmux-16 unit, together with two Ethernet modules. In addition, a channelized T3 module incorporated in central site units with a T3 hand-off interface, to groom the unframed T1 links originating from multiple remote gateways. • Channelized T3 and STS-1 modulesThe above modules transform the IPmux-16 to a grooming device, receiving up to 28 T1 TDMoIP streams and grooming them into channelized T3 at the central site.
