At LCC we focus on developing a route-map with the client to design projects with the best possible quality.


  • Designs of different transmission technologies:

    • Mobile access: Radio link networks ( PMW ), FTTN and MBH .

    • Fixed access: FTTH (Fiber To The Home), HFC (Hybrid-Fiber-Cable) and GPON (Gigabit-capable Passive Optical Network) networks.

    • Transport: DWDM , CWDM, Carrier Ethernet, SDH and PDH networks.


  • High Level Design (HLD) activities:

    • Network viability analysis (topology, capacity, unavailability and latency).

    • BoQ of necessary equipment.

    • Knowledge of the hardware equipment of the main manufacturers in the market (Huawei, Ericsson, Alcatel-Lucent, Nokia Siemens and ZTE).

    • Network diagram designs.


  • Low Level Design (LLD) activities:

    • Types of transmission jobs:

      • Equipment swaps.

      • Services balance.

      • New integrations.

      • Route migrations.

      • Equipment expansion.

    • LLD transmission design (interference calculation, radio frequency band assignment, antennas, lambda channel assignment, types of network protection and routing protocols, among others).
    • On-site and remote line of sight analysis for new microwave radio links.

    • Simulations of network configurations (radioelectric spectrum and power balance in fiber optic links).

    • Generation of transmission equipment configuration scripts (OLTs, switches and routers) according to customer regulations.

    • Technical environment designs.

    • Frequency assignment procedures with the Ministry.

    • Management and monitoring of work orders and scheduled jobs.

    • Databases inventory of the main operators in Spain (Orange, Masmóvil, Lyntia, Vodafone and Telefónica).

At LCC we work side by side with the client to ensure each network intervention and deploy the best possible solution.


  • Integration of new transmission equipment:

    • OLT (Huawei MA5800-X7 / X15 / X17) and fiber nodes (Huawei CMC MA5833).

    • Routers (Huawei PTN910 / 1900/3900/6900, ATN910 / 950, NE40, NE8000, Nokia 7750).

    • Switches (Huawei S6320, Nokia 7450 ESS).

    • Radio links (Huawei RTN380 / 950/980, Alcatel MPR9500, Nokia-Siemens Flexipacket A1200 / A2200, Ericsson TN6P / 20P and CN510 / 810).

    • WDM : (Huawei OSN1800 / 6800/8800/9800 and Nokia 1830).


  • MBH, FTTH and WDM migrations:

    • FTTN (Fiber to the node) or MM (Middle-Mile).

    • Transmission equipment swap (PTN, ATN, NE40 or CMC).

    • Creation of WDM MAN (Metropolitan Area Network) and LH (Long Haul) services.

    • OLA and ROADM migrations .

    • Balance & retuning of WDM services.

    • Preparation of scheduled jobs (checking of alarms and IPs, script testing and assurance of viable transmission).

    • Field technician support (on-site).

    • Checklist of “Ready for On Air”.

    • End-To-End 2G, 3G, 4G and 5G routes configuration.

    • Knowledge of the hardware equipment of the main manufacturers in the market (Huawei, Ericsson, Alcatel-Lucent, Nokia Siemens).

    • Knowledge of the network managers of the main market manufacturers: U2000 and NCE from Huawei, DXX and SOEM from Ericsson, SAM from Alcatel-Lucent and TNMS and NetViewer from Nokia Siemens.

At LCC we care, together with the client, about the optimization of processes and continuous improvement of the transmission networks.


  • Enabling performances on transmission equipment.


  • Real-time monitoring and incident analysis.


  • Ad-hoc troubleshooting on network incidents.


  • Checklist of network elements and configurations.


  • Optimized handbook of solutions to network incidents.


  • Implementation of preventive tasks.


  • Babysitting activities on the client.


  • Backoffice for analysis of performance KPIs (DCR, CSSR, RSSI, traffic loss, throughput, micro cuts or latency).


  • Standardization of scenarios in the laboratory.


  • Traffic balance, configuration changes and re-routing of affected services.


  • Reporting on network status, capacity, performance, and recommendations for improvement.

At LCC, thanks to the End-To-End management of transmission projects, we have deep extensive experience in network audit analysis to ensure the quality of every deployment.


  • At each milestone, the necessary checks are carried out to ensure quality:

    • Design audit.

    • Inventory audit.

    • Implementation audit.


  • Process applicable to all layers of the network:

    • Radio mobile access.

    • Transmission mobile access.

    • Fixed access.

    • Transport.

    • Core / BBIP.


  • Active network configurations status audit to anticipate future problems:

    • Ports configuration.

    • Software versions review.

    • Radio links modulations.

    • Full-duplex working mode.

    • Physical interface information (PIR).
