IPmux®-216 provides legacy services over packet networks. The device converts the data stream from its user E1/T1 ports into packets for transmission over the network. These packets are transmitted
via the IPmux-216 Ethernet network port to the PSN. A remote pseudowire device converts the packets back to their original format.
IPmux-216 features an internal bridge, operating in VLAN-aware and VLAN-unaware modes. VLAN stacking is 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 flow. User traffic can be prioritized according to VLAN priority, DSCP, IP Precedence or per port.
Ingress and egress rate can be limited per user and network port. Rate limitation is configured per packet type.
- Comprehensive compliance with pseudowire/circuit emulation standards including TDMoIP, CESoPSN, SAToP, CESoETH and HDLCoPSN
- Industry-leading adaptive clock recovery mechanism suitable for cellular backhaul 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, and 8 or 16 TDM service ports
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 pseudowire devices and circuits. The Service Center’s intuitive GUI, “point andclick” 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.
The Syslog protocol is used by IPmux-216 to generate and transport event notification messages over IP networks to the central Syslog server. The Syslog operation is compliant with the RFC 3164 requirements.
SNMPv3 support introduces a user-based security model, enhances authentication and encryption techniques, and ensures management traffic security. Each management and service host has a separate MAC address. As the unit provides one default gateway, the user can also specify static routes to enhance the IP routing capabilities of the management and pseudowire traffic. Software is downloaded 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.
