Microwave radio tower with dish antennas against a dusk sky

Networks builtfrom the towerto the core.

Telecommunication consulting and systems integration. We procure the equipment, design the licensed links and deploy the core, access and voice layers — then hand you a network that is documented, monitored and supported.

Seven disciplines, one integrator

Most projects stall where one vendor's scope ends. We carry the whole chain — procurement, radio design, core routing, access, voice and monitoring — under a single engineering team.

Licensed microwave radio design

Path surveys, link budgets, frequency coordination and licensing paperwork, then installation, alignment and acceptance testing on site.

  • Path profile and Fresnel clearance studies
  • Frequency coordination with the regulator
  • 1+1 hot standby and space diversity builds

Cisco core network deployment

Routing and switching built to a documented design — from distribution switches through to BNGs and the edge that carries subscriber traffic.

  • Cisco router and switch configuration to standard
  • BNG and subscriber termination integration
  • OSPF, BGP and MPLS design and migration

Checkpoint firewall deployment

Perimeter and internal segmentation with Checkpoint security gateways, policy sets written around how your business actually moves data.

  • Gateway and management server build
  • Rule base, NAT and VPN configuration
  • Log review and change control handover

FTTH and FTTx, end to end

From the core through the BNG and into the OLT, out to the splitter and the customer's ONT — designed, spliced, tested and documented.

  • OLT integration into the core and BNG
  • Splicing, OTDR testing and as-built records
  • Residential and business drop provisioning

VOIP for call centres and hotels

Voice platforms sized for real call volume — contact centre queues, recording, and private intercom for hotels, estates and corporate campuses.

  • Call centre queues, IVR and agent routing
  • Hotel and campus private intercom systems
  • SIP trunking and PSTN gateway integration

Linux and Windows server deployment

Infrastructure services built properly the first time: DHCP, DNS and Active Directory, hardened, patched and handed over with runbooks.

  • DHCP, DNS and Active Directory design
  • Linux server builds and hardening
  • Backup, patching and documentation

Network monitoring with Zabbix and Cacti

If it isn't measured it isn't managed. We deploy the monitoring stack, build the templates and tune the alerting so the right person hears about it first.

  • Zabbix and Cacti deployment and templating
  • SNMP polling, graphing and capacity trends
  • Alert routing to your NOC or ours

Twelve years of field deployments, not slideware.

Core Telecomms Network Services Company Limited was started by engineers who spent their early careers on towers, in exchanges and in data centre aisles. That background shapes how we work: we survey before we quote, we test before we hand over, and we leave behind documentation your own team can use.

How we engage

Microwave & transmission

Links that hold their margin in the rainy season

We design every hop with real fade margin, not the optimistic number on a datasheet. Path surveys are done on site, antennas are aligned to specification, and acceptance tests are recorded so you can prove the link performs when the weather turns.

Where a route needs resilience, we build 1+1 hot standby or space diversity and configure the switching so a failure is invisible to the traffic above it.

Core, access & fibre

One rollout from the core to the customer's ONT

Core routers, BNGs and OLTs are integrated as a single design, so subscriber traffic is provisioned end to end rather than patched together after the fact. We handle the Cisco configuration, the fibre splicing, the OTDR testing and the as-built records.

For ISPs and estates rolling out FTTH, that means fewer handover gaps between contractors and a network that is ready for activation on day one.

Uptime is a design decision, not a promise.

Every network we hand over carries a documented design, a tested acceptance record and a monitoring stack watching the links, the routing and the services. When something degrades, you see it on a graph before your customers feel it — and you have a named engineer to call, not a ticket queue.

Five ways to bring us in

Whether you are building from greenfield or steadying a network that has grown faster than its documentation, we scope the engagement to fit the job.

Greenfield build

You have spectrum, a site or a licence and a blank sheet. We run the survey, produce the design pack, procure the equipment and build the network through to acceptance — including the monitoring that keeps it honest afterwards.

Subject to site access and survey availability

Two engineers, one day on site. We review your existing links, routing, fibre and monitoring, then leave you with a written findings report and a prioritised remediation plan — yours to act on with or without us.
