IPmux-11 TDM Pseudowire Access Gateway DESCRIPTION • IPmux-11 is a TDM pseudowire access gateway extending TDM-based services over packet switched networks. It also serves as an Ethernet-based access device. TDMoIP PERFORMANCE • IPmux-11 provides a legacy over FEATURES • TDM pseudowire CPE/CLE, • • • • • • • offering TDM circuit emulation over a packet-switched network (PSN) and controlled Ethernet access Built on TDMoIP technology, implementing the emerging IETF, MFA Forum, ITU-T and MEF standards for Pseudo-Wire Emulation Edge-to-Edge (PWE3) E1/T1 emulation over MPLS, IP and Ethernet networks Support for both framed (full or fractional) and unframed E1/T1 Configurable jitter buffer to compensate for network packet delay variation Dedicated external clock port Ensures TDMoIP priority by QoS marking: ToS, VLAN priority or EXP bits Operates opposite other members of RAD’s TDMoIP family of products (IPmux-1E, IPmux-14, IPmux-8/16, Gmux-2000, Megaplex ML-IP) • One Ethernet network port; two Ethernet user ports, offering Transparent Ethernet bridging User data bandwidth and access control through rate limiting and VLAN filtering VLAN tagging and double tagging • Typical applications: E1/T1 (voice or data) leased line replacement PBX PSTN access Multiservice TDM/Ethernet CLE/CPE • Management via ASCII terminal, Telnet host, Web terminal or SNMP-based network management station • Provisioning and monitoring of TDMoIP services using the RADview Service Center for TDMoIP applications • Compact, 1U high enclosure PSN solution transmitting E1/T1 streams over packet switched networks. The device converts the data stream from its user E1/T1 port into packets for transmission over the network. The addressing scheme of these packets is IP or MPLS. These packets are transmitted via the IPmux-11 Ethernet network port to the PSN. A remote TDMoIP device converts the packets back to TDM traffic. • High-performance buffering and forwarding techniques are used to achieve end-to-end processing delay as low as 3 msec. • Configurable packet size allows to achieve proper balance between PSN throughput and delay. • A jitter buffer compensates for packet delay variation (jitter) of up to 300 msec in the network. • Assigned, IANA-registered UDP port number for TDMoIP simplifies flow classification through switches and routers. IPmux-11 TDM Pseudowire Access Gateway TDMoIP QoS • IPmux-11 supports VLAN tagging and priority labeling according to 802.1p&Q. TDMoIP packets are assigned a dedicated VLAN ID and 802.1p bit. • The ToS or Diffserv of the outgoing TDMoIP packets are user-configurable. This allows the TDMoIP packets to be given a higher priority in IP networks. • EXP bits are used for QoS marking of the TDMoMPLS traffic in MPLS networks. TDMoIP TIMING • Synchronization between TDM devices is maintained, by deploying advanced clock distribution mechanisms. The clocking options are: Internal – the master clock source for the TDM circuit is provided by IPmux-11’s internal clock oscillator Loopback – the transmit clock is derived from the E1/T1 port’s receive clock Adaptive – the clock is recovered from the PSN External – an external clock source to synchronize the device via its station clock port. • System clock ensures clock resilience by using master and fallback timing sources for clock redundancy. IPmux-11 also provides system clock output via external clock connector. TDM INTERFACE • One standard E1 or T1 port provides connectivity to any standard E1 or T1 device. • E1 and T1 interfaces support the following: Integral LTU/CSU for long haul applications G.703 unframed and G.704 framed modes CAS and CRC-4 bit generation (E1) D4/SF and ESF framing (T1) Robbed bit (T1). ETHERNET INTERFACE • IPmux-11 provides the following Ethernet ports: One network port (UTP or fiber optic) Two user ports (both UTP or UTP and fiber optic). • Each Ethernet port supports: Port-based rate limiting for bandwidth control Port-based VLAN membership for ingress traffic restriction Port-based VLAN tagging Double VLAN tagging (VLAN stacking) Bridging and filtering. ETHERNET CAPABILITIES • IPmux-11’s internal Layer-2 Ethernet switch provides three Ethernet ports. One port serves as a network interface and the other two serve for user Ethernet traffic. • Each Ethernet port supports: Configurable port-based rate limiting for bandwidth control Configurable port-based VLAN membership for ingress traffic restriction Configurable port-based VLAN tagging; a VLAN tag is added resulting in a double tagging (VLAN stacking) when an already tagged frame is switched. • The device supports standard IP features, such as ICMP (ping), ARP, next hop and default gateway. APPLICATIONS Figure 1. LAN and TDM Services over a Fiber Optic Ethernet Link IPmux-11 TDM Pseudowire Access Gateway DIAGNOSTICS • External and internal loopbacks can be used to check TDM link connectivity. • The following E1/T1 physical layer performance statistics are available: LOS, LOF, LCV, RAI, AIS, FEBE, BES, DM, ES, SES, UAS and LOMF. • IPmux-11 performs an internal built-in test (BIT) after power up. The results of the test are visible via the local terminal. • LAN and IP layer network condition statistics, such as packet loss and packet delay variation (jitter) are monitored and stored by the device. • Fault isolation, statistics and event logging are available. • To enhance fault condition reporting capabilities, remote IPmux-11 transfers RDI, LOS and AIS conditions received from the remote E1/T1 device to the local E1/T1 device via the PSN. MANAGEMENT • IPmux-11 can be configured and monitored locally via an ASCII terminal, or remotely via Telnet, Web browser or RADview. • Management traffic can run over a dedicated VLAN. • The RADview Service Center and Element Manager packages control and monitor TDM over IP (TDMoIP) devices and circuits. The Service Center’s intuitive GUI, “point-and-click” functionality and easy-to-follow wizards increase the efficiency and accuracy of the service provisioning process. • Software download is supported via the local terminal, using XMODEM, or remotely, using TFTP. After downloading a new software version, IPmux-11 automatically saves the previous version in non-volatile memory for backup purposes. Similarly, copies of the configuration file may be downloaded and uploaded to a remote workstation for backup and restore purposes. Figure 2.
