Chapter 1 Introduction Chapter 1. Introduction 1.1 Welcome In telecommunications, TDM over IP (TDMoIP) is the emulation of time-division multiplexing (TDM) over a packet switched network (PSN). In the case of the IPM-4SE, TDM refers to E1 signals, while the PSN is based on Ethernet. TDM over IP is a type of pseudo wire (PW). However, unlike other traffic types that can be carried over pseudo wires (e.g.

Chapter 2 Installation Chapter 2. Installation 2.1 Introduction The Installation chapter will cover the physical installation of the IPM-4SE, 4-Port E1 IP Multiplexer, the electrical connections, interface connections and cabling requirements. A brief overview of the functional components such as main unit and management options will also be outlined in this chapter.
Chapter 2 Installation 2.5 Electrical Installation With an AC power model, AC power is supplied to the IPM-4SE through a standard IEC C14 3-prong receptacle, located on the rear of the unit. Any national power cord with IEC C13 line plug may be used to connect AC power to the power module. With a DC model, DC -48V is connected to the terminal block located on the rear of the module, observing the proper polarity.
Chapter 2 Installation 2.7 Basic Configuration and Diagnosis The IPM-4SE units are shipped in pre-configured pairs. One is labeled CO (central office) and the other labeled CPE (customer premises equipment). Simply place the CO unit towards the E1 clock source (SDH multiplexer, BSC, carrier, etc.) and place the CPE unit connecting to the E1 recovery equipment (DSU/CSU, BTS, customer, etc.).
Chapter 3 Configuration and Operation Chapter 3. Configuration and Operation 3.1 Description IPM-4SE consists of the front panel and the rear panel. The views and description of front and rear panels are shown in Figure 3.1 and 3.2. The IPM-4SE units are shipped in pre-configured pairs. One is labeled CO (central office) and the other labeled CPE (customer premises equipment). Be sure to carefully check the model's sticker.
Chapter 3 Configuration and Operation 3.3 Rear Panel Introduction There are three parts to the rear panel of the IPM-4SE, shown in Figure 3.2. Figure 3.2 IPM-4SE 4-Port E1/T1 Rear Panel View 3.3.1 WAN Interface: The Ethernet WAN interface is an RJ-45 connector with LED There are green and yellow LED indicators: • Green Link (Link Up/Down Status) • Yellow Act (TX/RX Active Status) 3.3.
Chapter 3 Configuration and Operation 3.7 Fault Report The alarms/status of NE node can be reported thru RS232 or Telnet (CLI command). The resource of alarms is only from TDM interface (E1) and the acronym alarm names are shown as follows. E1LOS: (E1 Loss of Signal) No E1 line connected to the specific E1 port. E1AIS: (E1 Alarm Indication Signal) AIS (all 1’s) signal input from the specific E1 port. PWLBIT: (Pseudo Wire L bit) Remote E1 port failure condition (LOS or AIS).

EX: srcnet 192.169.1.28 255.255.255.0 192.169.1.
Chapter 3 Configuration and Operation 3.10 Factory Default Scripts When delivered from the factory, the units are paired as CO and CPE for immediate point-to-point use, with all 4 E1s enabled, unframed, and LAN enabled. Because these units operate at Ethernet Layer 2, we address the remotely connected pseudowire by MAC address. If the device sticker has been lost, or if the MAC address has been inadvertently changed, the MAC for both the MNT port and WAN port can be viewed through the CLI.

Chapter 3 Configuration and Operation 3.11.4 Using the IPM in a Routing Environment The IPM-4SE is designed for use in an Ethernet environment (Layer 2). However, with proper configuration, the IPM-4SE will work in a routing environment. Knowing the Router MAC is the key. It is very easy to discover the router’s MAC address. From a PC, open a command window, ping the gateway, then check the ARP table using the command arp –a. Make note of the gateway MAC on each subnet that has an IPM.
