2. Operations and Maintenance Terminal
2.1. Introduction to the OMT
The Operations and Maintenance Terminal (OMT) software runs on all of the devices in the iDAS system. The
interface to the OMT is WebOMT. WebOMT is based on a web browser and is compatible with most common browsers
such as IE and Google Chrome. WebOMT is customized for the IDAS and is used for query, debugging and configuration.
An NMS can only connect to the Master AU, therefore the Master AU is known as the host. However, to maintain the
IDAS system locally, a technician can access the whole system through any one of the devices in the IDAS system (Master
or Slave AU, EU or RU). For example, the technician may connect a laptop to the RU, log into the WebOMT and query the
DAS topology. The device name on the topology diagram is a URL link to the WebOMT on the selected device. Therefore,
by clicking on the device’s name, the technician can access any other device easily, regardless of which device’s WebOMT
they initially logged into.
2.2. Accessing the OMT
There are several methods for accessing the OMT:
 Wired access
 Wireless access
 USB access
Unless indicated otherwise, the examples use the Windows XP operating system and Internet Explorer 8 web
browser.
2.2.1. Wired Access to the OMT on the Master AU
In the IDAS system, the Master AU is defined as the host, with the other AUs, EUs and RUs defined as slaves. See
Section 3.6 for Master/Slave AU selection.
The default IP address of the AU is 10.7.3.200, while the slaves have no fixed IP address. The IP addresses of the
slaves are assigned by the host automatically, based on the network topology.
To set up wired access to the OMT, use the following procedure:
1. Connect a PC to the CONSOLE port on the front panel of the Master AU with a network cable.
2. Change the TCP/IP properties (see Figure 2-1):
