Solution Strategy & Implementation

Strategic Multi-Site Deployment

PertSol deployed iNterceptor across three critical IPLC locations, establishing a consistent interception framework while supporting the operational requirements of geographically distributed network environments.

Advanced Traffic Capture

PertSol iNteliProbes were deployed to capture mirrored IPLC traffic through existing splitters and optical taps. This approach enabled efficient monitoring while minimizing infrastructure changes and deployment complexity.

Real-Time Interception & Monitoring

The platform enabled near real-time interception of Traffic Content (TC) and Intercept Related Information (IRI), supporting continuous monitoring and secure delivery of authorized information.

Centralized Compliance Framework

A Central Warrant System, Mediator, and iNterceptor Monitors were deployed to streamline lawful access, monitoring, and standards-aligned information delivery in accordance with ETSI requirements.

Scalable & Secure Architecture

The solution leveraged existing infrastructure, supported multiple high-capacity interfaces from E1 to 100Gbe and OTU2 to OTU4, and incorporated encryption and integrity validation to secure intercepted information.
