IPmux-24 - Tessco

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
