Case studies
Romtelecom – AXE 10 Project
Intrarom participated in a huge project for digitization and modernization of fixed telephony network of the national operator Romtelecom. Within this project, during the period 2000-2004, Intrarom produced, installed and ensured the support for more than 1.000.000 digital lines as well as for different transmission equipment and networks, using latest technologies and equipment produced by INTRACOM for transmission and access systems, and by INTRACOM under ERICSSON license for AXE 10 exchanges.
Romtelecom - Network Synchronization Project
Network synchronization is important for switching, transmission and data networks, such as Plesiochronous Digital Hierarchy (PDH), Synchronous Digital Hierarchy (SDH), and Asynchronous Transfer Mode (ATM) networks. It is essential that the telecommunication systems in these networks is synchronized to meet the Quality of Service (QoS) demanded by network users. For the synchronization of Romtelecom fixed network, INTRAROM developed a three-level structured network with 93 nodes. The network uses high precision clock, Cesium based and GPS synchronization equipment. For this network a unique central node provides the network management for the whole system. The equipment supplier is Oscilloquartz Company from Switzerland, one of the world’s leaders in design and manufacture of high-quality quartz crystal oscillators, which demonstrated to be a very good partner, by delivering besides the equipment, know how, training and on site support.
Romtelecom – DWDM Project
The Dense Wavelength Division Multiplexing is a transmission technology that combines, on the same fiber, different wavelength, each transmitting a different channel. With this technology the bandwidth of the existing optical network will be increased, in effect one fiber will be transformed into multiple virtual fiber. The DWDM – based network is able to carry different type of traffic (SDH/SONET, IP, ATM) at higher speeds (2,5Gb/s, 10Gb/s, Ethernet Gb/s). This new network can be managed from one central point due the new management platform MV38 provided by Marconi. The optical network elements are represented by:
| - |
optical terminal multiplexers/demultiplexers with or without in line amplifiers and with optical add drop function. |
| - |
optical repeaters represented by wideband amplifiers that can amplify all the 32 wavelengths supported by the system. |
The project was subdivided in two phases, each phase including one ring of DWDM equipment (in total 32 nodes). During the project, INTRAROM provided teams of trained engineers, which based on the technical data sent by ROMTELECOM, executed activities of site survey, designed the floor plans for the DWDM system, devised the network diagram and materials list.
The equipment supplier is Marconi Company from Italy, which demonstrated to be a reliable partner, by delivering besides the equipment, know how, training and on site support.
Transelectrica Project – Romanian National Power Grid Company
The project consisted in a complex ICT system in order to lead to Transelectrica integration in UCTE (The Union for Coordination of Transmission of Electricity). This created the frame for real time data exchanges between the Romanian national electricity company dispatching center and those of the neighbor countries. The project benefited of Phare funds.

Network architecture is based on Cisco, Sun and HP technologies, these assuring state-of-the-art solutions for infrastructure, intercommunication and services.
The implementation had a high level of complexity because it did not take place in a close, private environment, but it was performed SS7 signaling and traffic interconnection with the fixed telephony network.
The offered services are: long-distance national Services (prepaid and postpaid), International Services, Voice VPN Services, PC-to-Phone Services and Supplementary Voice Services (Call Forward Unconditional, Calling Number Delivery Blocking (CNDB), Call-by-Call selection of CND/CNDB, Three-way calling, Malicious Call ID, etc).
Romtelecom – Corporate Data Network - CDN Project
In order to leverage the advantage of an impressive backbone and core infrastructure, Romtelecom started an ambitious program of upgrading its Corporate Data Network. Intrarom will deliver LAN and WAN equipment, together with the related implementation and technical support services. The result after the first phase is one of the most extended countrywide IP networks, based on CISCO technology.
Romtelecom CDN network was designed to fulfill the requests for high performance and high availability for all mission critical applications that forms the core of incumbent operator’s information technology infrastructure. The CDN Network is the main data network in Romtelecom and it covers all country from the main sites to the smallest ones (app. 150 sites).
For this reason the “turn-key” project contains the state of the art elements in all the implementation fields: WAN/LAN equipment, Network Management System, Security and related services, based on Cisco technologies.
Romtelecom – IP MPLS Network Project
Intrarom implemented IP-MPLS Core and Edge Network for Romtelecom, a next generation technology from CISCO that adds a high degree of flexibility to the existing transport network and represents a significant step in the transition from the traditional circuit-switched networks towards IP-centric architectures. Such a technology opens the way for a whole new range of convergent services.
Main Business objective for Romtelecom MPLS network is to provide IP VPN, L2 services. The IP MPLS backbone of Romtelecom will be a consistently hierarchical network with a clearly dedicated core, which interconnects network edge (aggregation) layer.
There are six Points of Presence, which are the core sites distributed around the country, and twenty-seven Points of Presence, which are the edge sites.
The interconnection among core routers follows the required topology, which is driven by the optical (DWDM) transmission infrastructure.
The interconnection between the edge and core routers will be provided by Ethernet services of the underlying SDH infrastructure. The SDH will provide point-to-point links for each edge-core connection.
The technology was implemented using Cisco equipment.
