Data SheetIPmux-24TDM Pseudowire Access GatewayTDM circuit emulationover packet-switchednetworks• Comprehensive support for pseudowire/circuit emulation standards includingTDMoIP, CESoPSN, SAToP, CESoETH and HDLCoPSN• Industry-leading adaptive clock recovery mechanism suitable for cellularbackhaul over packet-based networks• Carrier-class/environmentally hardened device• Extensive OAM and performance monitoring capabilities• Three auto-detecting Gigabit or Fast Ethernet SFP- or UTP-based ports, andone, two or four TDM service portsIPmux®-24 provides legacy services overpacket networks. The device converts thedata stream from its user E1/T1 ports intopackets for transmission over thenetwork. The frame format of thesepackets is IP or MPLS. These packets aretransmitted via the IPmux 24 Ethernetnetwork port to the PSN. A remotepseudowire device converts the packetsback to the original user traffic format.PSEUDOWIRE FUNCTIONALITYThe ASIC-based architecture provides arobust and high performance pseudowiresolution with minimal processing delay.The Access Company

IPmux-24TDM Pseudowire Access GatewayThe unit supports various pseudowireencapsulation methods, including TDMoIP,CESoPSN, SAToP, CESoETH (MEF 8) andHDLCoPSN.Proper balance between PSN throughputand delay is achieved via configurablepacket size.A jitter buffer compensates for packetdelay variation (jitter) of up to 180 msecin the network.PSEUDOWIRE QoS/CoSEthernet networks – outgoing pseudowirepackets are assigned a dedicated VLAN IDaccording to 802.1q and marked forpriority using 802.1P bits.IP networks – outgoing pseudowirepackets are marked for priority usingDSCP, ToS, or Diffserv bits.MPLS networks – outgoing pseudowirepackets are assigned to a specific MPLStunnel and marked for priority using EXP bits.PSEUDOWIRE TIMINGEnd-to-end synchronization betweencircuits is maintained by deployingadvanced clock recovery mechanisms.Clock recovery conforms to G.823 andG.824 traffic interface usingG.8261-defined scenarios.Advanced clock recovery conforms toG.823 synchronization interface usingG.8261-defined scenarios and achieves16 ppb clock accuracy.The system clock ensures a single clocksource for all TDM links. The system clockuses master and fallback timing sourcesfor clock redundancy. IPmux-24 alsoprovides system clock input and output viaan optional external clock port.TDM INTERFACEOne, two or four E1 or T1 ports provideconnectivity to any standard E1 or T1device.The E1 and T1 interfaces feature:• Integral LTU/CSU for long haulapplications• G.703 and G.704 framing modes• CAS and CRC-4 bit generation (E1)• D4/SF and ESF framing (T1)• Robbed bit (T1).Figure 1. 2G/3G Cellular Backhaul

Data SheetETHERNET INTERFACEThe following Ethernet ports are available:• One network port• One network/user port• One user port.The Ethernet ports accept a wide range ofGigabit and Fast Ethernet SFP-based fiberoptic and electric, as well as built-in UTPinterfaces.The unit can also be ordered with FastEthernet interfaces only (IPmux-24/FE).ETHERNET CAPABILITIESIPmux-24 features an internal bridge,operating in VLAN-aware andVLAN-unaware modes.VLAN stacking can be used for trafficseparation between different users orservices, by defining a service providerVLAN ID per customer or service. WhenVLAN stacking is used, a service providerVLAN tag is added to the user traffic andremoved from network traffic. Bothservice provider VLAN ID and serviceprovider VLAN priority can be defined.IPmux-24 provides four priority queues foreach port or pseudowire traffic flow. Usertraffic can be prioritized according toVLAN priority, DSCP, IP Precedence or perport.Ingress and egress rate can be limited peruser and network port. Rate limitation isconfigured per packet type.ETHERNET RINGThe unit employs Resilient Ethernet Ringtechnology to construct a self-healingEthernet fiber ring topology (ringresiliency is similar to that of SDH/SONETnetworks). In case of link failure on anysegment of the ring, the pseudowiretraffic is rerouted within 50 ms. A singlering supports up to 16 nodes.ETHERNET LINK PROTECTIONThe unit supports link aggregation (LAG)based on 802.3ad requirements.Dual homing technology (1:1) allowsIPmux-24 to be connected to twodifferent upstream devices.PSEUDOWIRE TRAFFIC PROTECTIONPseudowire traffic can be backed up atthe pseudowire connection level. Thisallows setting a different path for theprimary and secondary PW bundles. Bothbundles can be routed to the same ordifferent destinations and operate in the1+1 and 1:1 modes.In the 1:1 redundancy with two remotedevices the PW bundles in the remoteunits operate in the “mate” mode. In thismode each device monitors traffic activityon a mate bundle and transfers data onlywhen the other bundle is inactive.Figure 2. Private or Leased Line over PSN

IPmux-24TDM Pseudowire Access GatewayETHERNET SERVICE OAM (802.1ag)The unit uses the end-to-end Ethernetlayer OAM protocol for proactiveconnectivity monitoring, fault verification,and fault isolation, according to the IEEE802.1ag and ITU-T Y.1731 requirements.LINK OAM (IEEE 802.3ah)Link-layer OAM according to IEEE 802.3ahis used for fault indication and loopbackactivation response.MANAGEMENTIPmux-24 can be configured andmonitored locally via an ASCII terminal, orremotely via Telnet/SSH, Web browser orRADview.Management traffic can run over adedicated VLAN.The RADview Service Center and ElementManager packages control and monitorpseudowire devices and circuits. TheService Center’s intuitive GUI, “point andclick”functionality and easy-to-followwizards increase the efficiency andaccuracy of the service provisioningprocess.IPmux-24 performs RADIUS clientauthentication. Using SSH and SSLencryption protocols allows securecommunication over potentially insecureIP-based networks.The Syslog protocol is used by IPmux-24to generate and transport eventnotification messages over IP networks tothe central Syslog server. The Syslogoperation is compliant with the RFC 3164requirements.SNMPv3 support introduces a user-basedsecurity model, enhances authenticationand encryption techniques, and ensuresmanagement traffic security.Software is downloaded via the localterminal, using XMODEM, or remotely,using TFTP. After downloading a newsoftware version, IPmux-24 automaticallysaves the previous version in non-volatilememory for backup purposes. Similarly,copies of the configuration file may bedownloaded and uploaded to a remoteworkstation for backup and restorepurposes.OAM AND DIAGNOSTICSThe following RFC-2495 E1/T1 physicallayer performance statistics are available:LOS, LOF, LCV, RAI, AIS, FEBE, BES, DM, ES,SES, UAS and LOMF.IPmux-24 performs an internal built-in test(BIT) after power-up. The results of thetest are visible via the local terminal.LAN and IP layer network conditionstatistics, such as packet loss and packetdelay variation (jitter) are monitored andstored by the device.Fault isolation, statistics and event loggingare available.Fault propagation initiates service portalarms, e.g. E1/T1 LOS, to reflect networkfault conditions. Alarms detected atservice ports are propagated to theremote pseudowire device via the packetnetwork.Preserves investmentin legacy equipment inmigration to PSN

Data SheetDiagnostic loopbacks can be activatedinband.Ethernet and IP-layer network conditionstatistics, such as packet sequence errors(loss or misorder) and packet delayvariation (jitter), are monitored and storedby the device.RAD’s TDM PW OAM mechanism verifiesconnectivity, measures round trip delayand prevents pseudowire configurationmismatch.The carrier-class version of IPmux-24includes an alarm relay mechanism. Theminor and major alarms are forwarded toa remote alarm device via dedicated pinsof the external clock RJ-45 connector.ENVIRONMENTIPmux-24/H is an environmentally hardenedversion intended for street-cabinet andcellular-tower installations.Notes: The /H version requires temperaturehardened SFP transceivers.Figure 3.
