Chapter 1 Introduction 1.1 Overview IPmux-8 and IPmux-16 (referred to as IPmux-8/16) are TDM pseudowire access gateways. IPmux-8/16 modules enable TDM circuits to be emulated over Packet Switched Networks (PSN). The devices convert the data stream coming from the TDM ports into configurable-sized Ethernet frames that are transported over the Ethernet port and vice versa.
Chapter 1 Introduction Installation and Operation Manual Applications Three typical applications are illustrated below: • Figure 1-1 shows IPmux-8/16 extending E1/T1-based services over IP. • Figure 1-2 shows enterprise connectivity over campus or Metropolitan Area Networks. • Figure 1-3 shows IPmux devices managed by the RADview Network Management System. Figure 1-1. Extending E1/T1-Based Services over IP Figure 1-2.
Installation and Operation Manual Chapter 1 Introduction Figure 1-3. IPmux Devices Managed by RADview Network Management System Features E1/T1 frames or DS0 bundles are transported over the network based on IP addressing. E3/T3/CT3 ports and framers are available for IPmux-16. Ethernet link redundancy to the network is supported when IPmux-8/16 is equipped with two Ethernet modules. The unit supports one or two 1- or 4-port Ethernet modules.
Chapter 1 Introduction Installation and Operation Manual IPmux-8/16 maintains synchronization between TDM devices by deploying advanced clock distribution mechanisms. The clocking options are: internal, loopback, adaptive, and external (for IPmux-16). IPmux-8/16 complies with the TDMoIP protocol. Management IPmux-8/16 can be managed via a local terminal, Telnet, or via RADview, RAD’s Network Management system. IPmux-8/16 has a DB-9 port for the local terminal connection for monitoring and control.
Installation and Operation Manual Chapter 1 Introduction The CT3 module provides: • Increased IPmux-16 T1 capacity - up to 56 T1 channels (28 × 2) on a single chassis – two CT3 modules in the same chassis • Transmission of up to 28 bundles per CT3 card – each bundle containing an unframed T1 as per G.
Chapter 1 Introduction Installation and Operation Manual VLAN-Based Bridging VLAN-based bridging is performed in according to IEEE 802.1Q requirements. Up to 64 VLANs are supported per 4-port Ethernet module. At ingress the bridge supports tagged, priority-tagged and untagged frames. 1-Port Ethernet Module The 1-port Ethernet module includes one full duplex Ethernet network port with autonegotiation support.
Installation and Operation Manual Chapter 1 Introduction • Total Transmitted Packet per Second (pps) – a previous IPmux-16 Ethernet module had a limitation on the total transmitted packet per second (pps) rate (see Throughput Limitations and System Usage Control). This limitation is not relevant for the current Ethernet card. • Larger Ethernet frame size support (see Throughput Limitations and System Usage Control).
Chapter 1 Introduction Installation and Operation Manual Two network topologies are supported: • Star (point-to-multipoint): Multiple remote locations transport one bundle each to a central site that is capable of grooming the bundles into its E1 or T1 channel (see Figure 1-7). • Mesh: Any-to-any connectivity is supported at the bundle (DS0) level (see Figure 1-8). Internal Cross-connect IPmux-8/16 allows for internal cross-connect of bundles between its E1/T1/CT3 ports.
Installation and Operation Manual Chapter 1 Introduction 1.2 Physical Description IPmux-8 and IPmux-16 are compact, easily installable standalone units. Rack mounting kits are available. Figure 1-5. IPmux-8 3D View Figure 1-6. IPmux-16 3D View The control port and indicator LEDs are located on the front panel of IPmux-8/16. For further details, see Chapter 3. Fuses, power supplies, and interface connectors are located on the rear panel of IPmux-8/16. For further details, see Chapter 2.
Chapter 1 Introduction Installation and Operation Manual 1.3 Functional Description IPmux-8/16 Ethernet modules connect the device to the network. Configuration and management are provided via the IPmux-8/16 local terminal, Telnet application, or SNMP such as RADview, RAD’s network management system. IPmux-8/16 modules support E1/T1 interfaces. E1/T1 bundles, composed of several timeslots (1–31 for E1, 1–24 for T1), can be defined.
Installation and Operation Manual Chapter 1 Introduction Operation Modes IPmux-8/16 operation modes for E1/T1 are: Note • Unframed • Fractional • Fractional with CAS. For IPMux-16 with E3/T3 TDM interfaces, unframed is the only operation mode. Unframed In the unframed mode, the incoming bit stream from each port (regardless of framing) is converted into UDP/IP over Ethernet frames. This option provides clear channel end-to-end service.
Chapter 1 Introduction Notes Installation and Operation Manual • Internal clock – the Tx clock is received from an internal oscillator. • External clock (IPmux-16 only) – the Tx clock is taken from the external clock input (ordering option). For CT3, there is an additional option to take the timing from an internal T1 line, as long as this T1 port is in adaptive mode. The other T1 lines can take their timing from this T1. • E3/T3 cannot use external clock as a clock source.
Installation and Operation Manual Chapter 1 Introduction Figure 1-10. IPmux-8/16 in External Clock Mode – E1/T1 E3/T3 Note Only IPmux-16 has E3/T3 ports. This topology enables point-to-point connectivity; in Figure 1-11 both IPmux-16 units have direct E3/T3 connectivity. In this timing configuration both mesh and star bundle connection topologies are supported. Figure 1-11.
Chapter 1 Introduction Note Installation and Operation Manual For E1/T1, when there are several bundles from different sources at the same E1/T1 port, the bundle that is used for adaptive clock regeneration for the port is the first bundle of every port. For example (E1): Bundle number 1 for port 1, bundle number 32 for port 2, bundle number 63 for port 3, bundle number 94 for port 4, etc.

Installation and Operation Manual Chapter 1 Introduction VLAN, according to IEEE 802.1p&Q, adds four bytes to the MAC layer of the Ethernet frame. The contents of these bytes: MAC layer priority and VLAN ID, can be set by the user. In this mode, only VLAN format frames are sent and received by IPmux-8/16. The following figure describes the VLAN tag format. 81 00 8 802.1D Tag Protocol Type (802.1QTagType) 6 VID CFI = 0 user_priority 5 4 1 Priority 8 1 VLAN ID Figure 1-15.
Chapter 1 Introduction Installation and Operation Manual PDVT (Jitter) Buffer IPmux-8/16 is equipped with a Packet DVT (Delay Variation Tolerance) buffer. The PDVT buffer or jitter buffer is filled by the incoming packets and emptied out to fill the TDM stream. • A jitter buffer overrun occurs when it receives a burst of packets that exceeds the configured jitter buffer size + packetization delay. When an overrun is detected, IPmux-8/16 clears the jitter buffer, causing an underrun.
Installation and Operation Manual Chapter 1 Introduction Where: N= TDM bytes/frame 48 TS = number of assigned timeslots (in unframed mode= 32 for E1, 24 for T1) Note For a bundle that contains a few timeslots (i.e. 1 to 3), the recommended number of TDM bytes/frame is 48 in order to prevent excessive packetization delay.
Chapter 1 Introduction Installation and Operation Manual Ethernet Redundancy With two Ethernet modules, IPmux-8/16 supports Ethernet redundancy to back up TDMoIP traffic if there is a failure in the Ethernet line. The system assigns the same IP and MAC addresses to each Ethernet interface, so that if a failure occurs, the data and management traffic will automatically switch to the second Ethernet module. The switching is transparent to the remote IPmux, and the switches and routers in the network.
Installation and Operation Manual Chapter 1 Introduction The switch modes are described later in this section. They are: • Transparent Note • Untagged • Tagged • Double tagged. When processing traffic IPmux-8/16 switch utilizes four queues for frame forwarding. This is why the switch combines VLAN priority into four groups 0–1, 2–3, 4–5, 6–7, preserving the initial hierarchy (frames with 0–1 priority are forwarded before frames with 2–3 priority).
Chapter 1 Introduction Installation and Operation Manual Table 1-5. Mode A Ingress Egress If a tagged frame enters a transparent port, it is switched to the other transparent port The transparent port transmits the frame unmodified (tagged) If an untagged frame enters a transparent port, it is switched to the other transparent port The transparent port transmits the frame unmodified (untagged) Table 1-6.
Installation and Operation Manual Chapter 1 Introduction Table 1-8. Mode D Ingress Egress If a tagged frame enters an untagged port, it is switched to the other untagged port The untagged port removes the tag, andtransmits the frame untagged If an untagged frame enters an untagged port, it is switched to the other transparent port The untagged port transmits the frame unmodified (untagged) Table 1-9.
Chapter 1 Introduction Installation and Operation Manual Table 1-11. Mode G Ingress Egress If a double-tagged frame enters the transparent port, it is switched to the double-tagged port • If the double-tagged port is not a member of the first VID of the frame, the frame is discarded • If the double-tagged port is a member of the first VID of the frame, it removes the firs tag and transmits the frame tagged.
Installation and Operation Manual Chapter 1 Introduction You can configure the TDM bytes/frame parameter in N × 48 bytes, where N is an integer from 1 to 30 (for E1/T1 or CT3) or 5 to 30 (for E3/T3). If you configure TDM bytes/frame to a higher value, you will reduce the IP/Ethernet overhead segment of the total packet, and thus can significantly reduce the total Ethernet throughput. On the other hand, packetization delay are increased; this contributes to a higher end-to-end delay.
Chapter 1 Introduction Installation and Operation Manual Default Gateway Configuration IPmux-8/16 supports a default gateway configuration. Normally, the default gateway should be on the subnet where the user wants to manage IPmux-8/16. Management IPmux-8/16 is designed for unattended operation. The IPmux-8/16 configuration (the complete collection of its operating parameters) is determined by a database stored in non-volatile memory.

Chapter 6 Troubleshooting and Diagnostics Installation and Operation Manual while the switches are responsible for giving the priority according to the VLAN info. Verify that the IPmux traffic has the highest priority in the relevant Ethernet network. ToS There are several RFCs (RFC791, RFC1349, RFC2474) that define how the IP ToS should be configured. The ToS is a byte located in the IP header (Layer 3).
Installation and Operation Manual Chapter 6 Troubleshooting and Diagnostics Normally these problems are solved by giving priority to the IPmux traffic over all other traffic. As can be shown, even though there is sufficient bandwidth, there might still be cases in which the traffic will be transmitted from all the sources at the same time and thus create a momentary load on the network element (router/switch), even when this load that does not exceed the available bandwidth.

Appendix B Boot Sequence for Downloading Software This appendix provides a description of the IPmux-8/16 boot procedure. The IPmux-8/16 software is stored in the flash memory in two sections, in the boot sector and in the file system. The boot sector holds a boot program that calls up the rest of the program from the file system. The file system can hold two compressed copies of the IPmux-8/16 code. One copy is called the operating file, and the other is called the backup file.
Appendix B Boot Sequence for Downloading Software Installation and Operation Manual Boot Sequence The IPmux-8/16 boot procedure comprises the following stages: 1. The boot program searches for the operating file in the file system: If the file exists, a message appears on the screen and the program continues. If the file does not exist, the boot program searches for the backup file, renames the file to Operating file (a message appears on the screen) and continues.
Appendix C SNMP Management This appendix provides specific information for IPmux-8/16 management by SNMP (Simple Network Management Protocol). The SNMP management functions of IPmux-8/16 are provided by an internal SNMP agent. The SNMP management communication uses UDP (User Datagram Protocol), which is a connectionless-mode transport protocol, part of the IP (Internet Protocol) protocol suite. This appendix covers the information related to the SNMP environment. C.
Appendix C SNMP Management Installation and Operation Manual Management Information Base (MIB) The MIB includes a collection of managed objects. A managed object is defined as a parameter that can be managed, such as a performance statistics value. The MIB includes the definitions of relevant managed objects. Various MIBs can be defined for various management purposes or types of equipment.
Installation and Operation Manual Appendix C SNMP Management MIBs Supported by the IPmux-8/16 SNMP Agent The interpretation of the relevant MIBs is a function of the SNMP agent of each managed entity. The general MIBs supported by the IPmux-8/16 SNMP agent are: • rfc1213.mib (except the interfaces view which is supported via RFC 2233) • ianaiftype.mib (defines the ifType) • rfc2233.mib (IF-MIB) • rfc1493.mib • rfc2665.mib • rfc1907.mib • rfc2493.mib • ces.mib • rfc2495.
Appendix C SNMP Management Installation and Operation Manual In general, SNMP agents support two types of access rights: Read-Only: The SNMP agent accepts and processes only SNMP getRequest and getNextRequest commands from management stations which have a Read-Only community name. Read-Write: The SNMP agent accepts and processes all the SNMP commands received from a management station with a Read-Write community name.
