RAD IPmux-11


IPmux-8 TDMoIP gateway from RAD provides a compact, simple to configure and easily scalable solution for transporting TDM E1/T1 services over IP and Ethernet-based networks. IPmux-8 takes data streams from up to eight E1/T1 ports and converts them into packets for transmission over the network. The addressing scheme of these packets is IP. The packets are transmitted via IPmux-8ís Ethernet ports to the network. A second TDMoIP gateway at the remote location converts the IP packets back to TDM traffic. The primary benefit of IPmux-8 is to allow transparent E1/T1 connectivity over layer 2/3 packet switched networks, both in carrier and enterprise environments. IPmux-8 is a standard IP device, supporting ICMP (ping), ARP, next hop, and default gateway capabilities. IPmux-8 complies with the TDMoIP protocol. It works in conjunction with RADís IPmux-1, IPmux-1E, IPmux-16, Megaplex ML-IP, Kilomux KML.11, and other third-party products that implement the TDMoIP protocol. IPmux-8 features a dry contact alarm port that can serve as a general-purpose input port. The alarms are classified into three categories, stored in the Event Log, and can generate a system trap that is sent to the NMS.

IPmux-8 application


IPmux-8 achieves end-to-end processing delay as low as 1.7 msec, using high-performance buffering and forwarding techniques.
IP packet size is configurable.
Greater packet length results in greater processing delay, yet a smaller bandwidth overhead.
Enhanced buffering mechanism compensates for packet delay variation (jitter) of up to 32 msec for E1 or up to 24 msec for T1.

IPmux-8 supports VLAN tagging and priority labeling according to 802.1 p&Q.
VLAN-based separation of user traffic is supported by applying a dedicated VLAN tag to every TDMoIP circuit.
The Type of Service (ToS) of outgoing IP packets is user-configurable. This allows an en-route Layer-3 router or switch, which supports ToS (or Diffserv), to give higher priority to IPmux-8 traffic for delay-sensitive applications.
Assigned, IANA-registered UDP socket number for TDMoIP simplifies flow classification through switches and routers.

Two types of service are offered:
- Unframed: Full E1/T1 circuits are transparently extended across the IP network, regardless of framing structure.
- Structured: A bundle of timeslots can be configured for fractional E1/T1 services over IP networks. CAS can be enabled.
- Multibundling (grouping timeslots originating from a specific E1/T1 port) can be performed for up to 31 bundles per E1 port and 24 bundles per T1 port, for transport over the network. Both mesh and star topologies are supported.
- IPmux-8 allows internal cross-connect of bundles between its E1/T1 ports.

IPmux-8 maintains synchronization between TDM devices by deploying advanced clock distribution mechanisms.
The clocking options are:
- Internal: The deviceís internal oscillator provides the master clock source for the TDM circuit.
- Loopback: The transmit clock is derived from the respective portís receive clock.
- Adaptive: The clock is recovered from the Ethernet network interface.

- Two Ethernet modules can be installed in the IPmux-8 chassis, providing the uplink to the packet network.
- Each module supports a single 10/100BaseT or 100BaseFx port.
- IPmux-M/ETH/UTP, IPmux-M/ETH/MM-LC, and IPmux-M/ETH/SM-LC modules support re-ordering when packets arrive from the network in the wrong order, without considering them as lost packets.
- Ethernet link redundancy to the network is supported when IPmux-8 is equipped with two Ethernet modules. E1 AND T1 MODULES
- Each E1/T1 module provides four standard E1/T1 interfaces, which enable connectivity to any standard E1/T1 device (see Ordering).
- Integral LTU/CSU can be enabled for line protection and long haul applications.
- Alarm detection and insertion are supported together with error statistics, SES/UAS statistics, LOS/AIS physical layer alarms and remote loop/local loop test modes. Standard E1/T1 alarms are supported end-to-end.

- Power supply is available for AC or DC.
- IPmux-8 features optional redundant power supplies.
