• Supply of 15x4x1.2 mm High Frequency Cable and 48 Core Fiber Optic Cable to İskenderun-Narlı Line Section and Installation of Necessary Equipment

Iskenderun Narlı route, which has a line length of approximately 195 km, was included among the fiber cable lines with this project. High frequency cables were also laid along with the fiber cable, enabling the use of open line telephones.

After the cable laying and termination was completed by the main contractor, all active devices and their installation and commissioning were completed.

There are 20 stations within the scope of the project. STM-16 and STM-4 SDH devices were installed in 10 and 10 of these stations, respectively. Ericsson brand SDHs were used within the scope of the project. All devices are connected in a hopping ring topology.

The main station of the system was determined as Toprakkale, from where integration was provided to the Adana campus of the 6th Regional Directorate. All components used in the system were designed as redundant.

Thus, both intra-station and inter-station voice traffic and dispatcher line voice traffic can be carried over the SDH infrastructure.
Within the scope of the project, two different needs were defined for voice communication.

Firstly, the need for office communication was solved as a remote subscriber. The second and basic need, the dispatcher system, was solved using the same switchboard. Telesis X1 switchboard was used within the scope of the project.

As a result of the developments made with the manufacturer company by taking into account the requirements of the dispatcher system, a solution accepted by the organization has emerged.

With this system, all voice traffic was recorded with a redundant system. Thus, a line of more than 500 km in total will be completed by our company.
