IPmux-216 TDM Pseudowire Access Gateway 

IPmux-216 TDM Pseudowire Access Gateway, Two popular models are IPMUX-216/AC/16T1/UTP/UTP/UTP,  IPMUX-216/ACR/16T1/NULL/UTP/UTP.

IPmux®-216 provides legacy services over packet networks. The RAD IPmux-216 converts the data stream from its user E1/T1 ports into packets for transmission over the network. The frame format of these packets is IP or MPLS. These packets are transmitted via the IPmux-216 Ethernet network port to the PSN. A remote pseudowire device converts the packets back to the original user traffic format. Two popular models are  IPMUX-216/AC/16T1/UTP/UTP/UTP, IPMUX-216/ACR/16T1/NULL/UTP/UTP.

The ASIC-based architecture of the IPmux-216 provides a robust and high performance pseudowire solution with minimal processing delay. The IPmux-216 supports various legacy over packet transport types, including TDMoIP, CESoPSN, SAToP, HDLCoPSN. Proper balance between PSN throughput and delay is achieved via configurable packet size. A jitter buffer compensates for packet delay variation (jitter) of up to 180 msec in the network.

Ethernet networks – outgoing pseudowire packets are assigned a dedicated VLAN ID according to 802.1q and marked for priority using 802.1p bits. IP networks – outgoing pseudowire packets are marked for priority using DSCP or IP Precedence methods. MPLS networks – outgoing pseudowire packets are assigned to a specific MPLS tunnel and marked for priority using EXP bits.

End-to-end synchronization between circuits is maintained by deploying advanced clock recovery mechanisms. Clock recovery conforms to G.823 and G.824 traffic interface using G.8261-defined scenarios. Advanced clock recovery conforms to G.823 synchronization interface using G.8261-defined scenarios and achieves 16 ppb clock accuracy. The system clock ensures a single clock source for all TDM links. The system clock uses master and fallback timing sources for clock redundancy. IPmux-216 also provides system clock input and output via an external clock port.

TDM INTERFACE of the IPmux-216
8 or 16 E1 or T1 ports provide connectivity to any standard E1 or T1 device. E1 and T1 interfaces support:

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)

IPmux-216 provides the following Ethernet ports:
One network port
One network/user port
One user port.

The Ethernet ports accept a wide range of Gigabit and Fast Ethernet SFP-based fiber optic interfaces. One or two ports can be ordered with built-in 10/100BaseT interfaces. The IPmux-216 can also be ordered with Fast Ethernet interfaces only (IPmux-216/FE).

IPmux-216 features an internal bridge, operating in VLAN-aware and VLAN-unaware modes. VLAN stacking can be used for traffic separation between different users or services, by defining a service provider VLAN ID per customer or service. When VLAN stacking is used, a service provider VLAN tag is added to the user traffic and removed from network traffic. Both service provider VLAN ID and service provider VLAN priority can be defined. IPmux-216 provides four priority queues for each port or pseudowire traffic. User traffic can be prioritized according to the VLAN priority, DSCP, IP Precedence or per port basis. Ingress and egress rate limitation can be activated per user and network port. The rate limitation is configured per packet types.

IPmux-216 can be configured and monitored locally via an ASCII terminal, or remotely via Telnet/SSH, 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.

IPmux-216 performs RADIUS client authentication. Using SSH and SSL encryption protocols allows secure communication over potentially insecure IP-based networks. 

Software download is supported via the local terminal, using XMODEM, or remotely, using TFTP. After downloading a new software version, IPmux-216 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.

The following RFC 2495 E1/T1 physical layer performance statistics are available:

IPmux-216 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.

Fault propagation initiates service port alarms, e.g. E1/T1 LOS, to reflect packet network fault conditions. Alarms detected at service ports are propagated to the remote pseudowire device via the packet network. Diagnostic loopbacks can be activated inband.

Performance monitoring is provided by Ethernet and IP-layer network condition statistics, such as packet sequence errors (loss or misorder) and packet delay variation (jitter), which are monitored and stored by the device.

RAD’s TDM PW OAM mechanism ensures connectivity verification, round trip delay measurement and pseudowire configuration mismatch prevention.
