| Testing and Commissioning of BTS / MW Equipment |
| |
| Aster undertakes the task of testing and commissioning of telecom equipment on site. It usually involves the following:
DLC (Digital Loop Carrier)
We have successfully completed the works of DLC to the reputed clients like, Airtel, TATA with UT Starcom equipment, the project includes:-
|
DLC rack and installation of cards like FXS, PRM, E1 and BRI will be installed by our engineers |
|
FXS cables routed at MDF frame and kroned. |
|
E1 cable routed at TX. rack and kroned. |
|
Power cables routed and connected to DLC rack and power up the DLC. |
|
| |
FSO
FSO projects have been successfully completed for the clients like Vodafone, TATA etc |
| |
|
Installation will be done for two link heads. |
|
Installation of MUX. |
|
Power-up to Mux and link head. |
|
| |
Alignment & Commissioning of linkhead
LOS (Line of Sight Survey) |
| |
Our Engineers prior to MW Installation also do Line Of Sight between these two sites and this. The following are the equipments used by our surveyors to complete the process successfully: |
| |
|
GPS |
|
Binoculars |
|
Altimeter |
|
Compass |
|
Digital Camera |
|
Topographic maps |
|
| |
The surveyors need to reach the site A where the survey has to be conducted and looks towards Site B for the Line Of Sight with the help of above said equipments.
All the obstruction which are observed in the path are recorded and applied in to the Software of Pathloss v4.0 to get determine the height with reference to AMSL (Above Mean Sea Level) of MW antenna and Azimuth be installed to get the LOS cleared. |
| |
MW Antenna Installation |
| |
|
The mounting accessories of the MW antennae will be inspected and the mounting arrangements will be organized for the required orientation. |
|
The antennae, the wave-guide locks, flexible wave guides will be fixed with due care taken to ensure reliable and proper RF connections. |
|
The outdoor radio unit & antenna support arms are finally fixed. |
|
Alignment of Antennae of the link will be done to achieve the required receiving signal level. |
|
| |
Rack Installation
The rack for the installation of indoor unit and other equipment will be installed in the equipment room by grouting the bolts in the floor. The rods will be used if additional support is required.
Installation & Commissioning of Multiplexers in MSC, BSC and Cell Sites |
| |
| |
|
Installing the mux in the rack and powering up from DC Distribution Box. |
|
Installing The NVM (Non Volatile Memory) cards in the Mux. |
|
Installing The DCDB in the rack. |
|
Power tapping from rectifier to DCDB |
|
Installing the tributary cables from mux to Digital Distribution Frame. |
|
Kroning the E1s in their respective krone modules (Tx, Rx). |
|
Labeling the krone modules like TXs and RXs, and tributary cables. |
|
Earthing the rack, and mux, from the earthing bar (less than 1 ohm) in the shelter. |
|
Commissioning of mux. |
|
Giving IP Address for DCC and Ethernet for management purpose. |
|
Checking all kroned E1s with giving local loops from PC by using Bit Error Rate (BER) Meter. |
|
Checking mux Tx power of all out ports. |
|
Checking the transmitting power of both the optical ports using power meter. |
|
Checking mux receiving sensitivity of optical ports by using variable mechanical attenuator. |
|
| |
Electrification in Shelters of Cell Sites
We undertake electrical projects which involves supply of material, earth pit work & shelter electrification.
Earthing System
The Earthing system is designed to achieve the uniform earth resistance of less than 1 ohm at the site. The grounding system consists of the following Sub Systems:
Earthing pits - 4 nos., one for lightning protection of Tower and Equipment Shelter, one for the Electronic Equipment inside the Shelter, one for the DG Neutral DG & Body earth earth and one for AC earth.
Earth conductor runs from the lightning protection system, Principal ground bar maintained as reference in the shelter for electronic equipment, DG neutral and DG body to the respective earth pits.
Resource Support Management
We are also providing resources for Installation, Commissioning and Integration for various esteemed vendors like Lucent, Siemens, Alcatel, Ericsson and Nortel along with latest equipments like Site MT-tels / Site Analyzers, RF Power Meter, High Graded Laptops, Variable / Fixed Attenuator, E1 Tester, Optical Fiber Scope, Frequency Counters, Optical Power Meter, Digital Earth Meter, GPS, Binocular, Digital Camera etc., and other tools.
Our Teams have experience of various systems such GSM, CDMA, WLL etc. from various telecom vendors |
