TSP / Telco Link Assurance Engineer based at Mumbai

Job Description:

Shift Pattern: 24/7/365 Rotational Shifts

Role Overview

The TSP (Telecom Service Provider) Link Assurance Engineer is responsible for
monitoring external carrier backhaul, dark-fiber transport, and third-party telecom
underlay circuits (such as Airtel, Tata, Jio, Vodafone-Idea, or BSNL). When a telco
circuit goes down or degrades, this engineer immediately logs the incident, drives
end-to-end coordination with the respective service provider's NOC and field teams,
and ensures service is restored within contracted timelines to maintain 99.5% link
uptime.

Key Responsibilities

 24/7 Telco Circuit Monitoring: Continuously monitor upstream carrier links,
leased line interconnects, and inter-city backhaul circuits on NMS platforms
for down states, high packet drop, latency spikes, and optical degradation.
 Immediate Telco Ticket Logging: Log incident tickets with the respective
TSP/Telco service desk within 5 minutes of a link failure, capturing exact
Circuit IDs, timestamps, and interface error logs.
 Aggressive Escalation & Follow-up: Track active outages against the telecom
provider's escalation matrix (L1 L2 Circle Operations Head), conducting
continuous follow-ups to drive rapid restoration.
 Loopback & Fault Localization: Run soft and hard loopback tests at local
media converters, Provider Edge (PE) ports, or telco demarcation units to
identify whether faults lie in the local loop, carrier fiber span, or last-mile
terminating equipment.
 Field Team Coordination: Dispatch and coordinate with on-ground fiber
splicing teams and telco patrollers for OTDR testing, fiber cut identification,
and optical power budget restoration.

 Link Restoration Verification: Confirm circuit stabilization post-restoration by
checking interface CRC error counters, packet-drop metrics, and running
continuous ping/latency sweeps before closing vendor tickets.

 RFO & Outage Logging: Collect valid Reason for Outage (RFO) documents
from carrier service desks and maintain accurate historical logs of link
downtime and vendor performance.

Key Performance Indicators (KPIs)

 Overall Link Uptime: Maintain monthly uptime across all monitored third-party
telecom circuits.
 Mean Time to Log (MTTL): Raise incident tickets with the respective telco
provider within of link-down alarms.
 Mean Time to Restore (MTTR): Coordinate restoration to achieve for
logical/equipment issues and for external physical fiber cuts.
 Telco Escalation Compliance: 100% adherence to defined escalation matrix
timelines when telecom providers fail to update tickets.
 RFO Collection Rate: Secure verified, written RFOs from telecom vendors for
100% of Sev-1 outages within 24 hours of normalization.

Candidate Qualifications & Skills

 Experience: 1–3 years of experience in an ISP NOC, telecom NOC, or carrier
coordinator role.
 Domain Knowledge: Solid understanding of telecom circuit types (ILL, P2P
Leased Lines, MPLS underlays, Dark Fiber, DWDM wavelengths) and carrier
demarcation handoffs (SFP transceivers, Media Converters, Ethernet).
 Basic Networking: Fundamental understanding of TCP/IP, ping/traceroute
diagnostics, interface link states, optical power levels (/ dBm), and loopback
testing.
 Coordination & Communication: Clear, assertive telephone and email
communication skills to effectively escalate issues with carrier NOCs and field
engineers under high pressure.
 Education: Diploma or bachelor’s degree in Electronics &
Telecommunications, Computer Science, IT, or equivalent.
