Chapter 1 Introduction 1.1 Overview IPmux-16 is a modular TDMoIP gateway. IPmux-16 modules enable up to 16 E1 or T1 circuits to be extended over IP networks. The device converts the data stream coming from the E1 or T1 ports into configurable-sized IP packets that are transported over the Ethernet port and vice versa. IPmux-16 offers end-to-end synchronization for TDM applications and large buffers, to compensate for the delay variation inserted by the network.

IPmux-16 Installation and Operation Manual Chapter 1 Introduction Features Management IPmux-16 can be managed via a local terminal, Telnet, or via RADview, RAD’s Network Management system. IPmux-16 has an RJ-45 port for the local terminal connection for monitoring and control. Software upload and download and configuration can be performed via the local terminal or via RADview. T1 T1 ports and framers comply with ANSI T1.403 standards. The T1 jitter performance is according to G.824, TR-62411.
IPmux-16 Installation and Operation Manual Chapter 1 Introduction tolerance at the receiving end, causing buffer underflows and errors to occur. IPmux-16 supports VLAN tagging and priority. Mode of Operation IPmux-16 can operate in three different modes: • Unframed full E1/T1 over UDP over IP over Ethernet • Fractional E1/T1 over UDP over IP over Ethernet • Fractional with CAS over UDP over IP over Ethernet.
IPmux-16 Installation and Operation Manual Chapter 1 Introduction buffer begins to overfill, the regenerated clock frequency increases to avoid overflow. If the buffer begins to empty, the Receive clock decreases to avoid underflow. • Internal Clock In this mode, the Transmit (TX) clock is received from an internal oscillator. This mode is useful for testing and diagnostic purposes. Standards G.703, G.704, G.706, G.823, ANSI T1.403, TR-AT&T62411, G.824, IEEE 802.3, IEEE 802.3D, 802.
IPmux-16 Installation and Operation Manual Chapter 1 Introduction Front Panel The control port and indicator LEDs are located on the front panel of IPmux-16. For further details see Chapter 2. Rear Panel Fuses, power supplies, the dry contact connector, and interface connectors are located on the rear panel of IPmux-16. For further details see Chapter 2. 1.3 Functional Description IPmux-16 modules support E1 or T1 TDM interfaces. The E1 and T1 modules have either four or eight ports.
IPmux-16 Installation and Operation Manual Chapter 1 Introduction Bundles composed of several timeslots (E1: 1-31, T1: 1-24) can be defined. Each bundle can be connected to a different destination bundle anywhere on the network. Up to 496 sub-E1 or 384 sub-T1 remote bundles can be attached to one central IPmux-16. Multibundling enables concentrating many remote sites with few timeslots to the same TDM channel at the central site.
IPmux-16 Installation and Operation Manual Chapter 1 Introduction • Adaptive: In this mode, the E1 or T1 Tx clock is regenerated using the Adaptive method. In this method, the fill level of the buffer receiving packets is monitored. If the buffer begins to overfill, the regenerated clock frequency increases to avoid overflow. If the buffer begins to empty, the clock decreases to avoid underflow. • Internal Clock: In this mode, the Transmit (Tx) clock is received from an internal oscillator.
IPmux-16 Installation and Operation Manual Note Chapter 1 Introduction When there are several bundles from different sources at the same E1/T1 port, the bundle that will be 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.

Packet Delay Variation PDVT (Jitter) Buffer IPmux-16 is equipped with a Packet DVT (Delay Variation Tolerance) buffer. The PDVT buffer or jitter buffer is filled by the incoming IP packets and emptied out to fill the E1/T1 stream. The buffer begins to empty out only after it is half full in order to compensate for packet starvation from the Ethernet side.
IPmux-16 Installation and Operation Manual Chapter 1 Introduction Ethernet Throughput Configuring the TDM bytes per frame (TDM bytes/frame) parameter, per bundle configuration, can reduce Ethernet throughput (bandwidth or traffic travelling through the Ethernet). This parameter controls the number of TDM bytes encapsulated in one frame. The TDM bytes/frame parameter can be configured to nX48 bytes where n is an integer between 1 and 8.

Appendix B SNMP Management Appendix B provides specific information for IPmux-16 management by SNMP (Simple Network Management Protocol). The SNMP management functions of IPmux-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. B.
Appendix B SNMP Management IPmux-16 Installation and Operation Manual • getNextRequest: Command for retrieving sequentially specific management information from the managed entity. The managed entity responds with a getResponse message. • setRequest: Command for manipulating specific management information within the managed entity. The managed entity responds with a getResponse message.
IPmux-16 Installation and Operation Manual Appendix B SNMP Management MIBs of general interest are published by the IAB in the form of a Request for Comment (RFC) document. In addition, MIBs are also often assigned informal names that reflect their primary purpose. Enterprise-specific MIBs are published and distributed by their originator, who is responsible for their contents.
Appendix B SNMP Management IPmux-16 Installation and Operation Manual SNMP Communities SNMP delimits management domains by defining communities. Each community is identified by a name, which is an alphanumeric string of up to 255 characters defined by the user. The IPmux-16 SNMP agent defines strings of up to 10 characters (case sensitive, numeric and alphabetical). Any SNMP entity (both managed entities and management stations) is assigned a community name by its user.
Appendix C Telnet C.1 General Telnet, which stands for Telecommunications Network, is a protocol that gives you the ability to connect to a remote machine, by giving commands and instructions interactively to that machine, thus creating an interactive connection. In such a case, the local system becomes transparent to the user, simulating a direct connection to the remote computer.
