IPmux-16 TDMoIP Gateway • IPmux-16 takes data streams from up to sixteen E1/T1 or up to two E3/T3 ports and converts them into packets for transmission over the network (see Table 1). The addressing scheme of these packets is IP. The frames are transmitted via the Ethernet modules to the network. A second TDMoIP gateway at the remote location converts the IP packets back to TDM traffic. • The primary benefit of IPmux-16 is to allow transparent E1/T1 and E3/T3 connectivity over Layer 2/3 packet networks, both in carrier and enterprise environments • IPmux-16 is a standard IP device, supporting ICMP (ping), ARP, next hop and default gateway capabilities. • IPmux-16 complies with the TDMoIP protocol, working in conjunction with IPmux-1, IPmux-1E, IPmux-8, Megaplex-ML-IP, Kilomux KML.11, and other third-party products that implement the TDMoIP protocol. APPLICATIONS • IPmux-16 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. PERFORMANCE • Type of Service (ToS) of the outgoing IP frames is user-configurable. This allows an en-route Layer-3 router or switch, which supports ToS (or Diffserv), to give higher priority to IPmux-16 traffic for delay-sensitive applications. • IPmux-16 can achieve 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. • An enhanced buffering mechanism compensates for packet delay variation (jitter) of up to 32 msec for E1, 24 msec for T1, and 20 msec for E3/T3. QOS SUPPORT • IPmux-16 supports VLAN tagging and priority labeling according to 802.1 p&Q. • User traffic VLAN-based separation is supported by applying a dedicated VLAN tag to every TDMoIP circuit, and a dedicated VLAN for managing the device. Figure 1. Extending E1/T1 or E3/T3-based Services over IP • Assigned, IANA-registered UDP socket number for TDMoIP simplifies flow classification through switches and routers. OPERATION MODES • Two types of service are offered: Unframed: Full E1/T1 or E3/T3 circuits are transparently extended across the IP network, regardless of framing structure. Structured: IPmux-16 can be configured on a per timeslot basis for fractional E1/T1 services over IP networks. CAS signaling is supported. • Multibundling (grouping timeslots originating from a specific E1 or 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-16 allows internal cross-connect of bundles between its E1 or T1 ports. TIMING • IPmux-16 maintains synchronization between TDM devices by deploying advanced clock distribution mechanisms. The clocking options are: Internal: The IPmux-16 clock’s internal oscillator provides the master clock source for the TDM circuit. Loopback: The transmit clock is derived from the respective port’s receive clock. Adaptive: The clock is recovered from the Ethernet network interface. External: The station clock port is available and may be used to synchronize E1/T1 interfaces. ETHERNET MODULE • Two Ethernet modules can be installed in the IPmux-16 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 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-16 is equipped with two Ethernet modules (see Figure 5). E1 AND T1 MODULES • Each E1 or T1 module provides either four or eight standard E1 or T1 interfaces, which enable connectivity to any standard E1 or 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 are all supported. Standard E1/T1 alarms are supported end-to-end. E3 AND T3 MODULES • Each E3 or T3 module provides a single, standard E3 or T3 interface. • 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 are all supported. Standard E3 or T3 alarms are supported end-to-end. POWER SUPPLY • The IPmux-16 modular power supply supports carrier environments. The maximum power supplied by one unit is 75W with maximum power consumption of 57W. • IPmux-16 features hot-swappable power supplies, enabling service to a power supply (see Figure 4 and Figure 5). DIAGNOSTICS & MANAGEMENT • IPmux-16 supports remote loop and local loop testing. End-to-end alarm generation and end-to-end AIS indication are also provided. In the event that a local E1/T1 port receives AIS, it is passed to the remote port via the Ethernet/IP network. If a local Ethernet port is not connected, an AIS indication will be generated both in the local and the remote devices. • On the E1/T1 or E3/T3 ports, SES and UAS statistics are collected in 15-minute intervals and are stored for 24 hours (96 intervals). E1/T1 physical layer alarms (LOS, AIS, LOF, LCV) are also supported. Figure 2. Extending E3/T3 Circuits over IP/Ethernet IPmux-16 TDMoIP Gateway • IPmux-16 features a dry contact alarm port (with a DB-9 connector), which allows the device to send/receive alarms by opening/closing the contact between the connector's pins. • IPmux-16 monitors LAN and IP layer network condition statistics, such as packet loss and packet delay variation (jitter). The events are stored in log files and SNMP traps are generated. • IPmux-16 performs an internal built-in test (BIT) after power-up. The results of the test are visible via the local terminal. • Software download is supported via the local terminal using XMODEM, or remotely, using TFTP. After downloading a new version of software, IPmux-16 automatically saves the previous version in non-volatile memory for backup purposes. Similarly, copies of the configuration file may be downloaded/uploaded to a remote workstation for backup and restore purposes. • IPmux-16 can be configured and monitored: Locally, via an ASCII terminal or over the local management port Remotely via Telnet or SNMP (RADview Service Center TDMoIP) The RADview Service Center package enables provisioning TDMoIP service and managing the TDMoIP gateways by providing a user-friendly graphical display that allows monitoring and configuring of multiple IPmux devices. Fault isolation, statistics and events gathering are available. The Service Center’s intuitive GUI interface, "point-and-click" functionality and easy-to-follow wizards increase the efficiency and accuracy of the service provisioning process.
