# Tmonitor Lawful Intercept

TelcoBridges' [Tmonitor](/products/tmonitor/tmonitor.md) provides a high-performance API-based network monitoring development platform for solution developers. Its cost-effectiveness makes the [Tmonitor](/products/tmonitor/tmonitor.md) the hardware of choice for lawful intercept activities.

Tmonitor devices perform non-intrusive, full-duplex monitoring, filtering, and analysis of traffic such as [SS7](https://tmediadocs.telcobridges.com/telecom-references/ss7-and-signalling/ss7) and [ISDN](https://tmediadocs.telcobridges.com/telecom-references/ss7-and-signalling/isdn) signaling, [HDLC](https://tmediadocs.telcobridges.com/telecom-references/transmission-and-lines/hdlc) frames, as well as raw traffic on T1/E1/JI or STM-1 interfaces at line speed, providing up to 100% packet capture. It features highly configurable on-board packet filters so that only relevant information is captured from traffic streams and stored. Tmonitor also allows service providers to also record up to 256 channels of voice traffic in the TM1000 and much higher in subsequent models.

Unlike software-based solutions running on the base station controller, Tmonitor devices impose no additional overhead on the core network equipment. Unlike a hardware probe, Tmonitor creates no additional latency and therefore no performance hit.

**One important note:** The very same Tmonitor hardware that is installed at a service provider and is used to respond to [lawful intercept](/products/tmedia/features-and-solutions/solutions/lawful-intercept.md) mandates can be used to perform [network monitoring](/products/tmedia/features-and-solutions/features/network-monitoring.md) activities and provide [location-based services](/products/tmedia/features-and-solutions/solutions/location-based-services.md). This allows service providers to maximize their investment by achieving additional business objectives, and in the case of location-based-services, actually monetizing the data generated by network activity.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://tmediadocs.telcobridges.com/products/tmonitor/features-and-solutions/features/tmonitor-lawful-intercept.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
