🔧 Tata ILL Installation Process: Step‑by‑Step Guide

Rohit, the CIO of a mid‑size e‑commerce firm in Gurugram, noticed that during flash‑sale events his order‑processing app slowed down dramatically, causing cart abandonments and revenue loss. After a quick audit, he realized the shared broadband pipe was the bottleneck and decided to switch to a dedicated Tata Internet Leased Line (ILL). What followed was a clear, step‑by‑step journey from the first phone call to the moment the green light turned on and the new link went live.

1. Free Site Survey – First Foot in the Door

The process officially starts with a free site survey. Positive Communication’s technical team visits your premises, checks the existing cabling, notes the point‑of‑presence (POP) locations, and measures the distance to the nearest fiber hub. This on‑site check determines whether a direct fiber drop is possible or if a last‑mile copper fallback is needed.

During Rohit’s survey, the engineer discovered a vacant duct in the building’s basement that could accommodate a new fiber strand, saving weeks of civil work. The survey report, delivered within 24 hours, includes a heat‑map of signal strength, a list of required equipment, and a rough timeline.

2. Feasibility & Design Check – Is It Really Possible?

After the survey, the design team runs a feasibility analysis. They cross‑verify the distance, check for any right‑of‑way constraints, and run a capacity simulation to ensure the chosen bandwidth (10 Mbps, 100 Mbps, 200 Mbps, or 1 Gbps) will be delivered without degradation.

For Rohit’s 200 Mbps requirement, the simulation showed a clear path with 0.5 dB loss, well within the acceptable margin. If any issue arises—like a blocked conduit—the team proposes an alternate route or a micro‑trenching solution.

3. Order Placement & Contract Signing – Locking the Deal

Once feasibility is confirmed, you receive a formal quotation (see ILL pricing page for current rates). The contract outlines the SLA (99.9% uptime with financial credit on breach), monthly fees, GST, and the minimum contract period.

Positive Communication offers a 2‑hour exact‑quote turnaround, and the contract can be signed electronically. Rohit signed a 12‑month agreement for 200 Mbps at ₹35,000 + GST per month.

4. Fiber Laying & Civil Works – Getting the Pipe in Place

With the order in hand, the deployment team schedules civil works. Depending on the distance, this may involve trenching, pulling fiber through existing ducts, or using aerial routes. The team coordinates with the building’s facilities manager to avoid disruption to other tenants.

In Rohit’s case, the fiber was pulled through the existing duct in 3 days, and a splice‑closure was installed at the entry point. The work is logged in a field‑service app, and a photo‑evidence packet is shared with the client for transparency.

5. Router Configuration & Static IP Allocation – Making It Work

After the fiber is live, a Cisco‑compatible router (or any approved device) is installed at the client’s demarcation point. The NOC configures the router with the static IP block provided by Tata TTBS, sets up VLAN tagging, and applies QoS policies to prioritize critical traffic like ERP and VoIP.

Positive Communication’s 24×7 NOC monitors the link during the first 48 hours, fine‑tuning parameters based on real‑time traffic patterns. Rohit’s IT team received a detailed configuration guide, and a remote session was scheduled to walk them through the firewall rules.

6. Go‑Live, Testing & Handover – The Green Light

Once the router is configured, a final end‑to‑end test is performed: ping latency, packet loss, and throughput checks using tools like iPerf. The SLA guarantees 99.9% uptime, and the NOC provides a performance dashboard accessible via the client portal.

After the test cleared all thresholds, the link was officially marked as “Live”. A handover document summarizing the configuration, contact points, and escalation matrix was handed over to Rohit’s team.

From the initial call to the go‑live, Rohit’s entire journey took 18 days – well within the industry average for a 200 Mbps ILL.
