RET – Browser Application
The CCU runs a web-server. RCUs and CCUs, as
part of a network, can be configured and controlled
through a standard browser, e.g. Netscape, Internet
Explorer – no additional software is required. The
RET system can be controlled over a long distance
directly on site.
The connection to each CCU is easily generated
simply by typing in its own individual IP address.
The website which appears contains all the
required control functions for normal service and
installation. In addition to permitting the configuration
and control of the connected RCUs and TMAs,
the CCU program also displays the device status,
command history list and various types of system
errors. Via the alarm interface all AISG alarms can
be read off.
It is also possible to perform CCU software updates.
The browser application is a helpful tool for

the installation team on site, especially during the
initial configuration of a RET system.
Each CCU, and with it each of the connected
RCUs, can be addressed and controlled individually.
Therefore, the browser application also offers a
practical solution for responding to new situations
by changing the individual downtilt angles quickly
and easily.

An OMC may control hundreds of sites. The
IP/Browser solution is not suitable for the easy
control of more than one CCU. Access to the
various CCUs takes place in a serial form, which
consequently takes up rather a lot of time. Further
adverse features of such a Browser solution for an
OMC are:
– No reference to site names.
– With HTML the whole page has to be transferred,
even if only one value changes (very time
consuming, especially with a modem).
is only required for new adjustments.
– The CCU access is organized by the ASM automatically.
– Fast transfer rates due to reduced data quantity
(especially with modem mode).
– Explorer enables “family-tree” structure, giving
regions and site names.
– The ASM offers the basis for a customized interface
connection to the OMC software.

Optimised solution: Antenna System Manager
The Antenna System Manager is a type of SNMPbased
software installed on the OMC computer.
The ASM offers the following features:
– The number of controllable CCUs and connected
AISG devices is unlimited.
– The current data is collected and permanently
updated in the OMC computer. The CCU access
