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)
3.3.2 AC Power Socket and Switch (On/Off switch for AC):
The power socket provides the power with an input range of AC 110 ~ 240V via standard IEC connector.
3.3.3 DC Power Socket and Switch (On/Off switch for DC):
The power terminal strip provides the power with an input range of DC -75 ~ -36V
3.4 Loopback Mode
The IPM-4SE provides two types of loopback: "E1 Remote Loopback" and "E1 Local Loopback". (Please
refer to Figure 3.4).

3.5 IP Configuration
The IP address, subnet mask address, and Gateway address of the management port (MNT) should be setup
thru RS232 console using CLI commands.
3.6 Interface Configuration
For the LAN configuration, the setting of traffic bandwidth is provided to ensure the quality of service in
TDM circuits with 16 throughput options of 50K, 100K, 150K, 200K, 250K, 300K, 350K, 400K, 800K,
1.6M, 3.2M, 6.4M, 12.8M, 25.6M, 51.2M and 100M, depending on the user's requirement. In addition,
setting 100M option will utilize all the available bandwidth to LAN with no QoS for E1 traffic.
For the E1 configuration, the LEDs will be lit after enabling the E1 channel and user can select the remote
output E1 channel for flexible cross connection purposes. A Jitter Buffer is also used to compensate for the
latency of real network traffic between two devices. The Jitter buffer includes 8 options which are 11, 23, 40,
75, 99, 145, 192, and 239 ms.
