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. ATM, Frame Relay, and Ethernet), TDM is a real-time bit stream, leading to TDM over
IP having unique characteristics. In addition, conventional TDM networks have numerous special features, in
particular those required in order to carry voice-grade telephony channels. These features imply signaling
systems that support a wide range of telephony features, a rich standardization literature, and well-developed
Operations and Management (OAM) mechanisms.
One critical issue in implementing TDM PWs is clock recovery. In native TDM networks the physical layer
carries highly accurate timing information along with the TDM data which is easily recovered using phase-
locked loop (PLL) techniques. However, when emulating TDM over PSNs this synchronization is absent.
TDM timing standards can be exacting, and conformance with these may require innovative mechanisms to
adaptively reproduce the TDM timing.
Another issue that must be addressed is TDM over IP packet loss concealment (PLC). Since TDM data is
delivered at a constant rate over a dedicated channel, the native Ethernet network may have bit errors. All
PSNs suffer to some degree from packet loss, and this must be compensated when delivering TDM over a
PSN.
1.2 Product Description
The IPM-4SE series is a "Multi-service (TDM and Ethernet) Over LAN/MAN" bridge, which transports one,
two, three, or four ports of ITU-T G.703 E1 and one LAN into Ethernet packets. Its target application shown
in Figure 1.2 is the transparent E1 port interconnection via the Ethernet network (using Ethernet packets).
Based upon RFC3916, the IPM-4SE series employs the latest Circuit Emulation System over packet
technology.

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).
PWRBIT: (Pseudo Wire R bit) Packet loss occurred at remote E1 port.
PWSEQNUMERR: (Pseudo Wire Sequence Number Error) Packet loss occurred for specific E1 local
port.
JBUFEMP: (Jitter Buffer Empty) Buffer empty occurred at specific E1 port. (typically from link
down or mis-configuration.) If link is good, increase the jitter buffer at the expense of latency.
JBUFOV: (Jitter Buffer Overflow) Buffer overflow occurred at specific E1 port. There is probably a
problem with bi-direction throughput of the Ethernet WAN link.
3.8 Save Configuration
After changing the configurations from CLI or Telnet, the "SAVE" action should be done to store the
configuration into non-volatile storage. This can avoid loosing settings if the device is rebooted or powered
off/on.
3.9 Command Line Interface Setup
3.9.1 Using HyperTerminal™ as Local Console Terminal
When logging into the HyperTerm, set up the terminal port as follows:
•Bit rate: 115200bps
•Data bit: 8
•Parity: none
•Stop bit: 1
•Flow control: none
•Login password: admin (factory default)
3.9.2 Telnet in for Remote Console Terminal
If using the "Telnet" command in an Operation System, such as Windows or Linux, the default port of the
IPM-4SE is 8888 instead of the standard port 23 for security issue. The default IP address of the management
port is 192.168.1.1 and net mask is 255.255.255.0. The IP address, therefore, of the Telnet Client needs to be
set in the IP range 192.168.1.2 to 192.168.1.254 and the same net mask. An example of a command line in
Windows would be the following:
C:\WINDOWS\system32> telnet 192.168.1.1 8888
The factory default login password in both serial console CLI and Telnet modes is "admin". The CLI user
commands are listed in the following table for detail and implemented on CLI and TELNET modes:
3.9.3 Setting CLI (Telnet) login password
Important: DO NOT FORGET the password once changed or you must return the unit to factory. There is no
back-door password or any recovery procedure.

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. Below is an example.
3.10.1 Determine Device MAC Address
CLI>m 4321
====== CLI: MW Test Functions ======
m 4321 OUI(xx:xx:xx)
===== Config: HW/SW MAC = 1 (HW_MAC).
===== Config: OUI-Addr = 00:02:AB.
===== Config: eth0 Addr = 00:02:AB:16:CD:13. <== this is NMS MAC Source
===== Config: eth1 Addr = 00:02:AB:16:CD:12. <== this is WAN MAC Source

The factory default scripts allow the units to connect with 4xE1 over any LAN environment. To quickly
modify these two scripts for your LAN:
1. Change the ‘srcnet’ IP address to the new IP you want for the WAN port.
2. Change the ‘ipset’ to the IP, Subnet and GW for the MNT (management) port.
3. Change the ‘ceschset’ IP address to be the WAN destination for the PW (the opposite IPM)
4. Make sure the ‘ceschset’ MAC address is the actual MAC address of the destination unit (opposite
IPM).
